Quotes from the Reviews - What People Say about:

Boot

Boot:
"Running it to boot windows only and broke in under a year."
_
"I got a blue screen and then it failed to boot to windows."
_
"Fast boot up and no more annoying harddrive spinning sounds."
_
"My wife was growing frustrated that her computer took so long to boot up."
_
"First tool I used I would get an error on boot."
_
"For me, enabling UEFI boot on my weird hybrid system actually added to the boot time."
_
"No warnings, no errors, just failed to boot up."
_
"Sure enjoy the quick boot time."
_
"(everything includes every program that would auto boot after windows) After this past fabulous year and some odd months, I will never have the patience for my OS being on an HDD again."
_
"I have had the Sandisk Extreme 240GB running in my Mac Pro for over a year and no problems, the very fast boot time of 16 sec hasn't changed in a year."
_
"Very pleased having this as my boot up HD in my new PC build! "

Capacity

Capacity:
"Buy when it's on sale, because the price fluctuates a lot, but I've got no complaints whatsoever, and I prefer the 240GB rating over others who claim 250 256 for what is really the same amount of SSD; ultimately, being an SSD, it will degrade, and I'd rather have the overhead for that built-in than rely on more capacity that slowly just goes away."
_
"The downside to upgrading is a more limited storage capacity."
_
"Unfortunatly it's capacity isn't the best, you must buy an external hard drive to keep most of your data."
_
"Both OWC and OCZ have already issued firmware updates that correct the problem, giving their customers the full speed capacity of their SSDs."
_
"Boot times are lightning fast and the capacity is just nice."
_
"It was also nice to spend under $350 for this much SSD capacity."
_
"I bought a late 2012 Mac mini, moved the SSD to the extra bay on the mini (keeping the 1TB internal hard drive inside it as well), and have created a screaming little monster of a machine (also max-ed out its RAM at 16GB).As soon as SanDisk and the other SSD manufacturers get the capacity of these drives up to that of rotational drives at reasonable prices, which will take a couple of years, I suppose, the rotational drive will be rendered completely obsolete."
_
"At about $1 Gb at the time, it was one of the cheapest drives available in this capacity and the best performing."
_
"Great capacity and speed."

Controller

Controller:
"Even Samsung who in frustration tried to corner the reliability market with controller of their own can't get it right!"
_
"This thing is at this point as reliable as a paper weight due to controller failures."
_
"That shouldn't mean the Ultra Plus is actually inferior, because well, although I've had nothing but good experience with it, the Extreme uses Sandforce 2nd generation controller and that has generated quite a few unhappy customers as far as I know."
_
"Research on this issue leads me to consider the built-on controller for this SSD may be failing."
_
"I noticed this SSD s not fully compatible with some motherboard controllers from reviews here and some web forumsMy MSI G70 serious Laptop (Sata3) with all tests I have done I barely crossed 210-240 mb s write readAnd I didn't get even 50 % of the rated performance."
_
"This Drive is equipped with the Sandforce 2281 Controller that is know to have a defective Firmware Version 5.0.1. which has broken TRIM."
_
"This thing is at this point as reliable as a paper weight due to controller failures."
_
"The new extreme II have a Marvel controller (the best, most stable high end SSDs use Marvel) that Sandisk was forced to write their own firmware for and they did so plus added another level of cache over the top of everything."
_
"I guess that's the difference between a reliable micron controller vs a dirt cheap chinese made sandforce, with a known history of issues."
_
"Samsung has a great SSD Memory Controller and provides excellent SSDs that have a great reputation for reliability."

Cost

Cost:
"What I did not like: Well, other than the cost of the drive as compared to non-SSD units, I have no complaints."
_
")- Only negative is cost."
_
"Beware of the hidden costs if you do this like I did:~$18 Power eSATA ESATA+USB to Slimline SATA 7+6P 13Pin Cable for connecting your removed optical drive."
_
"I admit, I wasn't looking for the best performing drive, and the cost was a factor as I mainly wanted to upgrade my system for the right price."
_
"SSD prices are well above standard hard drives in price per MB, but if you are looking to speed up your system, this will not disappoint and it's well worth the cost."
_
"This has been the most cost effective upgrade to my desktop."
_
"Add the 240 as storage with enough RAM to make a ramdisk and u can fly Since my days with Pentium 4x86 machines I have never seen anything as fast as these for the cost AMAZING"
_
"I bought this as one of Amazon's Warehouse Deals, so the cost was very reasonable."
_
"Compared to upgrading to a new iMac, it's definitely cost effective."
_
"Happily, cost per GB for SSD's are dropping and this is makes the upgrade even more cost effective."

Firmware

Firmware:
"Further, using the SanDisk Toolkit to update the firmware to R211 failed totally even after several attempts."
_
"New firmware contain TRIM improvements but you won't be able to upgrade as sandisk's firmware iso can't benormally burned to usb stick and booted from there (shame on apple here too)."
_
"I'm still hopeful that SanDisk tech support will come up with a better solution, but for now be advised that if you have a new Mac Mini or iMac with USB 3 ports, it's likely that you will not be able to apply firmware updates to this SSD inside those machines."
_
"Update:Apparently the problem with the firmware update software is that it does not work properly with Macs that have USB 3 ports."
_
"One caveat: It will probably come shipped with older firmware that exhibits a TRIM problem, causing performance degradation over time."
_
"After checking that the firmware is outdated, I updated the firmware from their website by burning the ISO and reboot."
_
"I would recommend checking the firmware right away before installing anything."
_
"SanDisk has continued to provided firmware updates which is great."
_
"I also have a Crucial M4 in another computer and I was able to run it's firmware update on this machine, so I know it's possible."

Installation

Installation:
"It ruined my installation and I had to reinstall."
_
"Installation is no problem but if you are restoring an image from an old hard drive the size should be smaller than your new SSD."
_
"Coupled with that, the computer suddenly(as in my graphics card is new and had zero problems before hand) started throwing blue screens over my video card(this problem continued even after removing the SSD the only way to solve the problem was to move it from 16x to 8x) I tried a transfer installation the first time, e. g tried to migrate OS with Sandisk software(DO NOT TRY THIS) from spinning disk to SSD,this failed, and lead to non-stop blue-screening, so I did a clean install, and the blue screen slowed down from once every couple of minutes to once or twice an hour."
_
"The physical installation was no problem, however the software was."
_
"Drive failed 94 days after installation."
_
"Again, I was pretty worried that I'd made a mistake with the purchase, but trying it again with my later laptop's installation cd (OS 10.6.3) I was able to retrieve her back-up through time machine with no hitches."
_
"The installation was extremely easy, transferring data was ridiculously fast (over 100GB in roughly 30 minutes)."
_
"Easy installation and quiet."
_
"I would recommend checking the firmware right away before installing anything."
_
"No problem fitting drive & installing OS W7 and then updating FW."
_
"Installation was quick and painless (note: make sure you have a torx screwdriver so than you can loosen up your hard drive's mounting bracket)."

Power

Power:
"The hard drive requires extra power if you are cloning your drive externally and that is the first problem."
_
"I have owned this piece of ______ for 2 weeks and am now unable to power it."
_
"In the case of my 2nd drive, I received a unit with a flimsy SATA power connector."
_
"(Especially if it is a standard mechanical drive) Now you know where it is and if the primary drive fails then remove the PC computer's power and unplug the failed drive and plug in the archived one and you are back in business."
_
"Here are the R211 improvements:- Improved TRIM Latency, TRIM Performance, Background Garbage Collection, Error Handling and Power Management- Fixed the normalized value calculation for SMART Attribute Power-On Hours."
_
"Beware of the hidden costs if you do this like I did:~$18 Power eSATA ESATA+USB to Slimline SATA 7+6P 13Pin Cable for connecting your removed optical drive."
_
"I should mention that the 17 seconds (as well as the 1:32 time), is starting from the moment I push the power button to boot up the computer."
_
"It use to take the laptop 3 to 4 minutes to boot from power on to able to work on it."
_
"Time from pressing power button to being able to type password on the login screenOriginal hard drive 1:09SSD 0:26Test 2."
_
"I was really looking forward to this at I've heard it uses less power, more reliable."
_
"The power benefits are also nice since laptops running on SSDs instead of HDD can last about 10-15% longer on the same battery charge when compared to HDDs."

Price

Price:
"Buy when it's on sale, because the price fluctuates a lot, but I've got no complaints whatsoever, and I prefer the 240GB rating over others who claim 250 256 for what is really the same amount of SSD; ultimately, being an SSD, it will degrade, and I'd rather have the overhead for that built-in than rely on more capacity that slowly just goes away."
_
"For the money, this drive is hard to beat."
_
"Read their writeup of these drives (Sandisk Extreme 480GB and Samsung 840 500GB), and you'll see that Sandisk is offering a great price on a great SSD, while Samsung is giving you their budget technology (not bad but not as good as the Samsung Extreme) at the same price as the Sandisk Extreme."
_
"So no this is not a good price vs value."
_
"The second disadvantage is the price per megabyte of a SSD versus a HDD."
_
"The only drawback is the price."
_
"If it says Sandisk Extreme, it's probably the best item for the money."
_
"Great SSD cheap and durable."
_
"Great price as well."
_
"Really good price, good performance and reliable, would recommend"
_
"A great solid disk with a good price."

_
"-----------------------------------------------------------------------------------------This is probably the fastest and most reliable SSD in its price class...except for it failing to deliver its rated speed due to defective firmware."
