Quotes from the Reviews - What People Say about:

Adapter

Adapter:
"I had not taken the hard drive out of its packaging (I bought it at a warehouse store and it was in painful packaging, so I figured I would just deal with it when I got my adapter)."
_
"I'm confused what the actual intended use for this adapter is...For Use With Backup Plus Portable Drives."
_
"I had a thunderbolt cable from a previous thunderbolt adapter that did not work so I was pleased to be able to test this product once more (and hoped it would work)."
_
"The worst thing about this Seagate adapter is that it doesn't come with a Thunderbolt cable, which at this time of writing is the better part of $40.With that out of the way, I plugged in my Samsung 830 256GB SSD and ran some tests."
_
"The other downside is that a Thunderbolt cable is not included with the adapter."
_
"There are a few downsides to this adapter."
_
"Well designed and flexible Thunderbolt adapter for a 2.5 drive."
_
"Because of this adapter I ended up getting 3 compatible external seagate drives."
_
"Hopefully seagate will continue with this form factor and will keep making compatible adapters in the future so I can keep my drives and use them with newer adapters."
_
"Would be nice to find drive enclosures made for this adapter though."
_
"I own the Desktop adapter version too, and that has worked great since day one - this version, though works to access a HDD for about 10 minutes, then makes my machine freeze."

Cable

Cable:
"I had replaced the first cable as it was damaged shortly after I started testing (it didnt come with a cable which is very odd as its not usable without one).The drives also did not fit as snugly as my other seagate enclosure."
_
"Amazon doesn't make it clear that this DOES NOT include the cable."
_
"First off, this device does not come with a Thunderbolt cable, something that they don't make clear on the packaging or this listing."
_
"Be aware: the only drawback is that this does not come with the Thunderbolt cable - so if this is your first Thunderbolt accessory, you need to buy a cable separately."
_
"The Only downside is that there is no Thunderbolt cable included, which costs around $40 extra."
_
"It also seems to get quite hot at times and finally, it does not come with a thunderbolt cable which is pretty ridiculous."
_
"I think it's a bit pricey as well, especially since it doesn't include a cable."
_
"Installation was easy; basically just plug in the Thunderbolt cable and slide the drive onto the sled."
_
"I placed a couple SSDs in a few and use them with all the GoFlex cables to have great, fast external drives to carry."
_
"now i gotta search for a good thunderbolt cable."
_
"It would be nice if Seagate could include a Thunderbolt cable given the price premium."

Connection

Connection:
"The connections are different and are not compatible."
_
"I tried a number of USB3 adapters and drive enclosures and most, if not all, of the devices that bridged the SSD to the computer had a negative affect on the connection speed (read and write).So far, the Seagate Backup Plus Portable Thunderbolt Adapter has been the clear winner."
_
"However, it worked for the first week only then it ceased working and my Mac is not able to see any of the Hardrives connected to it."
_
"I popped the USB Adapter off the drive, inserted this new Thunderbold adapter and was able to connect to my new MacBook Pro with no problem."
_
"It provides a nice way to leverage thunderbolt connections for external drives and bare SSD's"
_
"I had a slower Seagate USB 3.0 HD that is from the same group, and it connected perfectly as well, although the bottom part of this device makes it not as elegant as the USB 3.0 connection."
_
"I have gotten good transfer rates from all the drives I have used this to connect to my computer."
_
"That's why I'm giving it 4 starsI've been very happy with my purchase, and would recommend this to anyone looking for a way to connect hard drives to their Apple computer and get the fastest speed available from their hard drive."
_
"I have been researching the fastest and most cost effective way to connect a SSD to a computer via a Thunderbolt or USB3 connection."

Cost

Cost:
"The Only downside is that there is no Thunderbolt cable included, which costs around $40 extra."
_
"Here are the negatives: - The cost to configure this technlogy isn't cheap."
_
"This has added several useful years to this machine, so the cost was easily justified."
_
"I am giving a 4 star because of the cost though it is the most cost effective way to harness the power of thunderbolt"
_
"It is the fastest and most cost effective option I have found."
_
"[...]But overall a good interface for the fastest portable storage ( at a reasonable cost ) when paired with an SSD."

Port

Port:
"Its main drawback is that it has only one Thunderbolt port so has to be at the end of the chain or plugged directly to the computer."
_
"This is a pretty great device with crucial ssd m4 I see 250mb s read write which is a big improvement over fw800 and esata and usb3.0 that i also have only big negative here is only one TB port."
_
"This Seagate docking port works without issue - I would love it except for the price which trends on the luxury side of computing."
_
"Well it may be if you're short on USB 3.0 ports or don't have said ports on your Apple computer...but outside of that scenario I fail to see any tangible benefits."
_
"First, unlike the desktop version of this adapter which has two ports, there is only one port on the portable version so you won't be able to daisy chain multiple drives."
_
"works well and frees up a USB 3 port"
_
"I just wish it had a USB 3.0 port, it works well with what it has."
_
"We are happy with this Seagate Backup Plus Portable Thunderbolt Adapter (Adapter only, will need a thunderbolt cable and a Seagate Desktop HD).Your computer will need to have a thunderbolt port (thunderbolt ready) as well."
_
"Well it may be if you're short on USB 3.0 ports or don't have said ports on your Apple computer...but outside of that scenario I fail to see any tangible benefits."
_
"This is a little slower than a direct connection to a SATA III port, but still very impressive!"

Price

Price:
"That would make it 5*.It's not the best value for the money but still a great product."
_
"This Seagate docking port works without issue - I would love it except for the price which trends on the luxury side of computing."
_
"I didn't run multiple iterations of the test, so take this with a grain of salt, but for my money, its hard to see why you would choose Thunderbolt, if your machine supports USB3."
_
"Here are the negatives: - The cost to configure this technlogy isn't cheap."
_
"Nice affordable Thunderbolt unit."
_
"Cheap for a Thunderbolt device, portable, and has good ventilation."
_
"To be able to convert my drives to thunderbolt is well worth the price."
_
"For the price andfor the sake of good engineering and convenience."
_
"If you need to transfer large video files from computer to an external hard drive this is well worth the money."

Read

Read:
"I am not sure if it is good for the long haul, and I have read that the Seagate could wipe out the hard drive due to some magnetization issues, but I have not had that problem."
_
"I got the read write speed upward 4000MB s. That got to be wrong somewhere (using Samsung Magician Benchmark) but then I used HD tune and CrystalDiskMark and got the same result."
_
"The problem was that the read write speeds were half of what I could get with a NexStar 6G USB 3.0 enclosure from Amazon with UASP (model is NST-266S3).So, it works fine as a Thunderbolt adaptor when its the spinning disk that determines the read write speeds."
_
"Has no problem maximizing SSDs' read write bandwidth."
_
"I read some of the reviews on this the one thing I found missing was what were some of the use cases and how people were applying this in their workflow."
_
"I tried a number of USB3 adapters and drive enclosures and most, if not all, of the devices that bridged the SSD to the computer had a negative affect on the connection speed (read and write).So far, the Seagate Backup Plus Portable Thunderbolt Adapter has been the clear winner."
_
"Every drive was able to be read and copy files, most of these drives came from XP and Win7 laptops."
_
"With a 7200 RPM seagate momentus I got well over 50MBs read & write, peaking at 60MBs on some operations when testing via Black Magic Speed Test (Mac OS X).I'd recommend the device for multiple reasons:1."
_
"Using the AJA and BlackMagic Design drive speed testing apps, the Samsung 840 Pro had read speeds of approximately 420MB s and write speeds of approximately 400MB s. This substantially beat the read and write speeds I was able to achieve using any of the USB3 to eSATA adapters enclosures I tested."
_
"This is a pretty great device with crucial ssd m4 I see 250mb s read write which is a big improvement over fw800 and esata and usb3.0 that i also have only big negative here is only one TB port."
_
"But, if you compare the speed when using an SSD, it is clear that the write (223 MB s) and read (351 MB s) are quite impressive."

Speed

Speed:
"I plugged an OWC 6G Mercury SSD into it no problem and it works perfectly and is super fast."
_
"I got the read write speed upward 4000MB s. That got to be wrong somewhere (using Samsung Magician Benchmark) but then I used HD tune and CrystalDiskMark and got the same result."
_

_
"I tried a number of USB3 adapters and drive enclosures and most, if not all, of the devices that bridged the SSD to the computer had a negative affect on the connection speed (read and write).So far, the Seagate Backup Plus Portable Thunderbolt Adapter has been the clear winner."
_
"Using a 1 TB portable Backup Plus drive, and three different adapters I ran performance tests using XBench 1.3.The (not very easy to read) results are below."
_
"I have a Mini-Mac (early version, USB-2 but no USB-3 ports), along with several Windows PC's, and I was looking for a way to connect an internal-style 2 terabyte hard drive to the Mini-Mac with good speed."
_
"I plugged an OWC 6G Mercury SSD into it no problem and it works perfectly and is super fast."
_
"Works great and is very fast!"
_
"Just LOVE how fast it works!"
_
"Fast & easy."

Transfer

Transfer:
"I purchased this portable adapter to transfer data off of my 3.5 drives... only to find out they're not compatible."
_
"File transfer is weird, I suspect it uses a buffer to copy - the progress bar seems to fly at first, then looks like suddenly pauses as though it has died for awhile, and then suddenly it is done copying."
_
"I have gotten good transfer rates from all the drives I have used this to connect to my computer."
_
"peed file transfer ... amazing , far, but far better than USB 3.0.Any SATA 2.5 HDD works with this interface, it will not look pretty, but it works and works well."
_
"I love seagate now I can make my portable hard drive more faster with thisit makes the transfer way easy and doubles the speedthe adapter easy to plug just remove the usb 3.0 and add the thunderbolt"
_
"The transfer speed is what is most appealing as well as it's dependable handling of data streams."
_
"I plugged in a Lacie 2tb hard drive into the port on the back of the adapter (daisy chain) and this feature worked well with no loss in speed during transfer test."
