Quotes from the Reviews - What People Say about:

Battery

Battery:
"It would help to have that extra peace of mind in the event of a UPS failing (batteries could have wore out and it is difficult to do frequent testing of the unit since you would have to switch off the power outlet and probably have a normal load on it to have the test be efficient)."
_
"Turn this feature off, you'll get less wear on your SSD, and the laptop will sleep and wake faster -- however, the one disadvantage is, if your battery goes completely dead, your system will lose its operating context, just like any computer when you yank the power."
_
"Unfortunately, my laptop gets about 1 3rd less battery life."
_
"I have an SSD in my laptop (Asus U20A) and it has benefited from slightly longer battery life, and lower temps as well as snappier operation."
_
"Works VERY well with Windows 8.1 Pro on older hardware (8530w), actually increased my battery life by a good 30 mins to 1 hour by upgrading."
_
"No problem since I got it - my Lenovo starts Super Fast, has a excellent extended battery life and run work related programs far better than that Fruit brand can handle."
_
"Everything runs smoothly and battery life improved as well."
_
"The battery still performs exceptionally well, even 4 years after the initial purchase, and the overall experience feels like I bought a new computer, but it's within the familiar housing."

Boot

Boot:
"Kept the old SSD as a backup in case I have a boot problem"
_
"I purchased this to replace the failed boot drive on my laptop."
_
"I was only hoping to get below 40 seconds but I was amazed that it cut down the cold boot time to an absurd 24 seconds after I reloaded all of the same software on the 840 Pro."
_
"My windows o. s. takes 13 seconds to boot, and I have a lot of junk on my system (services to start)."
_
"It used to take almost 3 minutes to boot before with all the extra junk that has to load."
_
"(OK, it am a fool, but I bought the same drive as a replacement when this failed because it was my boot drive and I couldn't wait for the RMA process."
_
"Windows boots very quickly (under 20 seconds), and overall responsiveness is great."
_
"Pros:Excellent read write speedsGreat boot SSD no problemsGood lifespan so far, 1 year plusCons:None so farOther Thoughts:Great drive worth buying."
_
"A Windows laptop that used to take 5 to 7 minutes to boot, now is ready to work in well under one minute."
_
"Pros:- So nice to boot my computer in a few seconds!"
_
"Runs fast and is the perfect size for a boot drive! "

Cable

Cable:
"I had to by the cable to link this to my USB2 connection and that was a bit scary but after all that it worked."
_
"i cant do a really long review but since i bought an ssd my computer has been running sooo much faster i mean i didnt even realise how much does it change your computer speed so this will definetly be a likeonly one dislike that i didnt know it doesnt come with cables and slot to get it to work on the pc so u should consider buying the cables wiht it if u wanna make it work on your pc"
_
"I had an issue when I installed it, but after a trip to the Apple store found the SATA cable was broken."
_
"Some people claim a SATA TO USB cable comes with the drive, but when I purchased both the 840 and 840 Pro drives, there was no cable included...I would have been really upset if I didn't have one, but luckily I have a backup device that I can use to get the SSD going with Samsung Data Migration."
_
"I know it's just a SATA connector + Power connector integrated into a single USB cable, but that would make imaging this thing a little easier on a laptop where you don't have any spare SATA & Power ports like you would on a desktop motherboard."
_
"I won't knock a star off for this since I knew about it going in, but it would have been nice if this had come with a SATA cable."
_
"I also think that for the price, Samsung could include a simple USB cable to make it easier for you to connect your drive as they suggest for migration purposes: my 830s each came with the cable and this one does not."
_
"- Make sure you plug the SATA cable into a SATA III Intel port for best results, and download the latest chipset drivers from your motherboards site."
_
"Luckily I was able to duct-tape the SATA cable to the SSD and it hasn't failed yet."

Case

Case:
"Kept the old SSD as a backup in case I have a boot problem"
_
"Beware, does NOT come with a mounting bracket so if your case doesn't already support SSD's then you'll need to purchase one separately! "
_
"I held out as long as I could, and pulled the trigger when I ordered a replacement work PC (Dell Latitude E5430 - highly *NOT* recommended, btw).In any case, before I ever turned on the computer, I replaced the 7200RPM drive with a 256GB 840 Pro and went from 4GB of crap Dell RAM to 8GB of Crucial RAM."
_
"Disk software is junk (as is usually the case).Other thoughts: Hook one up to realize how truly retarded and mythological Windows Experience rating really is."
_
"In order of reliability importance, I want my data drives to be the most reliable, and secondly my boot drive because I can always reinstall the operating system in a worst case scenario."
_
"It's also sleek and compact to fit in anyone's case."
_
"I was pleasantly surprised when this was not the case."
_
"It was easy to install into the Hard Drive Bays in my case and connecting the appropriate cables was a snap."
_
"well that is not the case."
_
"I used the Silverstone Tek 3.5-Inch to 2 X 2.5-Inch Hard Drive HDD SSD Bay Converter, Silver (SDP08) and had no problems installing this drive in my desktop tower case."

Connection

Connection:
"I had to by the cable to link this to my USB2 connection and that was a bit scary but after all that it worked."
_
"Together with the added memory I am able to perform a several thousand character search (DNA sequence) through a several million character sequence in about a minute (was not possible before).There were issues with the original installation where my boot was still around ~40 seconds, and if the computer was rebooted after losing complete charge it would have wifi issues and not being able to connect unless I restarted again."
_
"(Problem ended up being the SATA Ribbon connecting the hard drive to the logic board) However I LOVE this new drive."
_
"The only issue I had was that the SSD connector broke off the FIRST time I tried connecting the SATA cable."
_
"internet connection is total junk."
_
"I have older mobo and CPU, Asus Sabertooth X58 and Intel i7 960 and they run great connected to the SATA 3 ports."
_
"I also think that for the price, Samsung could include a simple USB cable to make it easier for you to connect your drive as they suggest for migration purposes: my 830s each came with the cable and this one does not."
_
"Don't forget to enable AHCI in your BIOS and make sure you are using a 6gb SATA 3 connection for best performance."
_
"The Samsung 840 Pro seemed to have a really good read write rate for the price (even if my SATA connection can't harness it all), and if I remember correctly, the best power consumption in the price range."
_
"Also if you have a fast internet connection at home, this allows you to take full advantage of it.."

Controller

Controller:
"Amazingly easy setup, included software allows you to clone prior drive for an easy upgrade, this does not use the intel sandforce controller so it does have have a bug which can cause BSOD problems when going into power saving mode."
_
"Also, make sure you have SATA 6GB s. My motherboard did have it but the controller is not very good so the large sequential writes are significantly slower specs."
_
"This review is actually 3 reviews in one because the first Sata3 controller I purchased did not work with the Samsung 840 Pro Series model# MZ-7PD512 512 gig SSD -- a problem with the controller not Samsung's SSD."
_
"Well it turns out those old Marvell controllers suck and give BSoD with SSD drives."
_
"nothing short of mind blowing, I got 2 of these babies in RAID0 (RAID 0 is when you get them working together for twice the speed and size of one)it gives me a 1GB s write and read speeds, using them with intel's built in RAID controller for the Z77 chipset and it's been great since, start up and shut down are almost instant, and my games don't take much time as it used to, and I was using a 10,000 RPM velociraptor 600 GB (RAID 0 same config) and yes it's worth it."
_
"Pros:FAST, Reliable, Easy to useSupports Sata 3 (6.0gbps)SSD controller is very well designed and programmedSoftware takes care of most optimizationWorks great with Windows 8Sturdy DesignVery thin and lightCons:None that I can tell so far."
_
"From looking around on the web, people don't seem to be super happy with the SandForce controller, a big part of the reason I chose this one."
_
"I highly recommend this controller if you are using it with the Samsung 840 Pro Series MZ-7PD512 512 Gig SSD."

Packaging

Packaging:
"Poor quality control as the packages should not have been shipped when the seals had been broke and the packages had obviuosly been opened."
_
"I wish moving the OCZ I had to the other system was as quick and easy, unfortunately OCZ doesn't package any imaging software with their similarly priced drives."
_
"The problem is that the manual that comes with the basic package describes only USB way of cloning and does not tell you that it will not work with the SATA interface."
_
"Wasn't sure if the drive was in good order since amazon did a horrible job of packaging the SSD but it seems to be in good order so they get a pass this time."
_
"Packaging: My only complaint is the cheapskate packaging."
_
"Packaging was great, and the product had world-class fit and finish."
_
"Packaging is nice and pretty.. and you get 2 Samsung stickers!"

Power

Power:
"I do not know how well this SSD compares to other SSDs in the same price power range, but I have been greatly satisfied with the purchase and recommend this for the 2010 macbook pros."
_
"We have not been able to find any better drives for our power users' laptops."
_
"Keep in mind that when you buy a SSD, you should seriously consider buying a power backup such as a UPS to prevent damage to your SSD investment due to power surges outages."
_
"Amazingly easy setup, included software allows you to clone prior drive for an easy upgrade, this does not use the intel sandforce controller so it does have have a bug which can cause BSOD problems when going into power saving mode."
_
"I use network simulators on my HP laptop and my HDD hard drive was not able to take the power of the simulators so I purchased the Samsung 840 pro series."
_
"While it is so fast that I barely even remember what a loading screen looks like and I wait for nothing, what is arguably more important, is that With the proper power settings in windows, I have this machine able to go in and out of sleep mode in under a second."
_
"Even after it 'looked' like it was ready to go, things were opening or working in the background, and it was a shade over seven minutes from press of the power button to actually being able to use the internet."
_
"I know it's just a SATA connector + Power connector integrated into a single USB cable, but that would make imaging this thing a little easier on a laptop where you don't have any spare SATA & Power ports like you would on a desktop motherboard."
_
"Highly recommended for power users of VFX and high grade software."
_
"Once you've installed your new hard drive in your MacBook put it all back together (alternately you can just plug in the power just to verify that you're all set which if you're new to doing this I recommend it) and turn it on."

Price

Price:
"Since my old HDD was failing, this was a good purchase and a good price at the time."
_
"Well....I guess the only complaint is that I could buy a 512GB one now for the price I paid 9 months ago but that's just how HDD pricing goes."
_
"I was so disappointed to waste this extra money for even worse performance."
_
"to get a replacement.... the price is up 40$ i am NOT happy."
_
"Everyone works very hard for their money and as we learned in business law....Caveat Emptor Let the buyer beware."
_
"While the 850 pro was released I still recommend this one over the 850 since the 850 pro counterpart is only 4% better in performance it is 30% higher in price per gb, which I don't see being worth the money in a increase you wouldn't be able to notice very well."
_
"Best price."
_
"Incredibly fast and a great price."
_
"The value (performance for the price) is excellent."
_
"Since my old HDD was failing, this was a good purchase and a good price at the time."

Quality

Quality:
"Samsung makes a quality SSD, no failure yet, but I have only owned it for little over +7 months."
_
"Amazon - my friend, started my Hero Jeff Bezos who has yet to become a zero and never will as long as Mr. Bezos is in charge (unlike it's brick and mortar counterpart which started out with all the right stuff by a great hard working Midwestern fellow named Sam which has now become nothing more than a Chinese product distribution outlet with a dubious reputation for quality, customer service, cramped, dirty, crowded interiors, long customer lines, and belligerent customers and store personnel - I think I'll stick with internet shopping whenever possible)."
_
"It is an SSD you cant really go to wrong with Samsung quality and I pray it is reliable."
_
"A quality SSD is one of the single best upgrades you can do to refresh an aging laptop and make it feel like new again."
_
"This drive has excellent quality."

Raid

Raid:
"You will not noticed any big user problem; however, in some raid 0 applications Microsoft may not recognize them as totally erased ( a problem with most ssd, except Intel?"
_
"As fast, if not faster than my old SAS setup in RAID, which this replaced when one drive failed."
_
"I have a good backup strategy so RAID 0 failure is not a concern."
_
"Only downside I had seen was that their software doesn't work in raid 0."
_
"I've had 4 Crucial M4's fail simultaneously in a RAID environment due to a firmware bug."
_
"Since the Samsung tool does not see drives in a RAID configuration, I am totally unable to update the firmware."
_
"i am using this to do Raid 0, it performs really well, and have no problems so far"
_
"Running 10 of these in an Adaptec raid 1 array for more than a year with no problems."
_
"After some research, I was able to get to boot in either IDE or Raid(AHCI) Mode, but the SSD said AHCI disabled and the speed was only marginally increased."
_
"this SSD works well the Magician software stinks (no RAID), its performance is not worth the extra cost."
_
"They behave well with my LSI raid card, and don't get dropped or falsely failed."

Read:
"Great reads and writes no hang ups or problems."

"Sequential Read : 498.693 MB sSequential Write : 344.846 MB sRandom Read 512KB : 421.340 MB sRandom Write 512KB : 364.018 MB sOnly problem, it's a little too expensive."
_
"I read reviews of people saying that it doesn't as well with AMD, but even if that's true, I still noticed a HUGE difference."
_
"Another drawback that these drives have (as you may have read in other reviews) is the hard limit on writes to the drive."
_
"The Magician Software did not read the upcoming failure."
_
"The drive's performance will almost immediately start to degrade from a stellar 550 Mb S Sequential Read Write and in in excess of 100,000 and 90,000 Random Read Write Input Output Operations per Second to less than 70,000 and 36,000 in three weeks depending on Bytes Written."
_
"Pros:Excellent read write speedsGreat boot SSD no problemsGood lifespan so far, 1 year plusCons:None so farOther Thoughts:Great drive worth buying."
_
"Interesting enough, on a win7 64 machine with 8 GB ram, after enabling rapid mode in Samsung Magician the benchmark sequentian read and write both were well past the rated speed mark on the bar and the random read writes improved dramatically."
_
"Works very well with read and writes as expected (around 500MB s R W on black diamond)."
_
"The 840 Pro is a solid, reliable hard drive with quick read and write times."
_
"Great reads and writes no hang ups or problems."

Reliability

Reliability:
"Yes this is the general benefit of SSD's however, this Pro has had no issues with read write speeds and they are among the best, if not the best, in reliability."
_
"No problems with either SSD on either machine after months - and from what I read about the 840 series reliability, I don't ever expect to have problems with them."
_
"Note that the advertized faster speed of evo applies towards its 500gb and 1tb versions only, The rest evo gb versions are slowerAlso with the slight better performance of evo, there is a drawback of reliability, which i didn't want to take my chances with."
_
"Great performance and reliability."
_
"I found that Samsung SDDs were near the top in terms of performance, but absolutely the undisputed best when it comes to reliability."
_
"I've been running these drives for several months now, so I believe that these drives will provide great reliability (knock on wood)."
_
"Only a couple of days old so time will tell on reliability, but so far I'm happy."
_
"Really happy with the performance & reliability."

Reliable:
"These drives are probably not the best performance per dollar drives, but they are very reliable."
_
"I hate this kind of thing, but it says it keeps the SSD more reliable."
_
"It is an SSD you cant really go to wrong with Samsung quality and I pray it is reliable."
_
"OCZ hasn't had the great reputation for reliable SSDs, but since they acquired Indilinx and stopped using the SandForce controller they have gained a lot of the SSD market back and have far more reliable SSDs."
_
"I know there are other discs out there that are faster, but I don't care about all the geeky benchmark speed tests - I wanted a pain free, reliable SSD, and after daily use for 1 1 2 years, I am very happy, and glad I got at least the 256GB version as it's big enough to store my photos on."

Setting

Setting:
"Samsung migration also failed to mention Win7 settings necessary to set up the target disk for good operation - delving into the dungeon that is Samsung's support (http: answers."
_
"There are some articles describing ways to modify the BIOS on computers to add this ATA Security setting if it is missing, but the instructions are rather complicated to modify the BIOS."
_
"Luckily one came w the Data Doubler I ordered from OWC, which now holds the HDD as a data drive in place of the optical drive (now in an external enclosure).Nothing bad to say about the drive so far - the only problems I ran into were with transitioning data & settings, and setting this to be the boot drive - all Mac OS X issues."
_
"I do have some advice to those who are intimidated with switching to SSD: do read up the many useful articles on the web to understand how you can check and change the settings in your computer to avoid frustration during data migration and setup."
_
"While it is so fast that I barely even remember what a loading screen looks like and I wait for nothing, what is arguably more important, is that With the proper power settings in windows, I have this machine able to go in and out of sleep mode in under a second."
_
"The Samsung Magician software seems to work fine, though, and is a great way to make sure your settings for this drive are configured exactly the way you want them."
_
"Samsung migration also failed to mention Win7 settings necessary to set up the target disk for good operation - delving into the dungeon that is Samsung's support (http: answers."
_
"I would recommend searching the internet for guides on setting up an SSD as your operating system drive before you begin."

"Installed this Samsung SSD into a new build, no problem with this drive, and it's really fast, and thr accompanying software and utility are also good."
_
"I thought something wrong, but how many time I try to do again, and it's same performance."
_
"Now I tried to copy the same file to and from the 840PRO SSD, the performance starts the same between 450MB s - 475MB s but the problem it drops down badly to 100-250MB s and stays like that till the end of the transfer."

Transfer

Transfer:
"And data transfer rates with USB 3.0 moving and copying is just ridiculous."
_
"The HD interface was only SATA 2, which can't take advantage of the 6GB SATA 3 transfer rate."
_
"To make a long story short, the migration disc that is supplied with this unit did not transfer the data immediately at the first attempt but at the second attempt it indicated that my original hard drive, which was also a solid state drive, was ready to be removed and my data had successfully been copied."
_
"I originally bought this to boost file transfer speeds on my laptop, and as an upgrade over a damaged HDD."
_
"My laptop isn't very low performance either, the SSD says it's connected to a Sata 6GB s port, (or so it says in magician) and the laptop even has Windows 7 Ultimate on it, I just don't get WHY file transfers are still so painfully slow."
_
"Data TransferThe main problem for me was the data transfer since I was completely swapping out my hard drive."
_
"Very easy to transfer the system from the hard disk."
_
"Pros:+ Quick file transfers.+ Great GB per $ ratio."
_
"Good but won't transfer more than two partitions"
_
"Easy data transfer and installation!"

Windows:
"Quick note - Samsung has not released Samsung Magician for Windows 10 yet so I am unable to use the rapid mode until then."
