Sabrent USB 3.0 to SATA External Hard Drive Docking Station for 2.5" or 3.5"' HDD, SSD [Support UASP] (DS-UBLK), Black

This review is for the "SINGLE" slot version. No (copy or clone) option.DS-UBLK has decent quality of construction for price. 3.5" Hard drive fits snug withno stress on hdd connectors. Eject mechanism works very easily. There is noquestion whether or not the hdd is fully engaged or fully ejected. I have not testedwith 2.5" drive. USB UASP xfer rates make a world of difference over standard BOT or"Turbo" protocols. Ensure your mobo has UASP port or you will only see standardUSB 3.0 BOT or turbo speeds. No driver was necessary. I did notice a significantperformance variation depending upon the type of file system used. The file type alsocontributed to speed fluctuation. Larger video ie. MP4 files xferred fastest. I'mguessing the same would hold true for any USB UASP device.GPT w/ NTFS = 100-150 MB/s (conistent)MBR w/ exFAT= 130-170 MB/s (burst only - actually slower than above GPT / NTFS)MBR w/ NTFS = 90-110 MB/s (consistent)MBR w/ FAT32= 70-90 MB/s (consistent)I saw no difference between standard and dynamic disk.Test hdds:All hdds have Win write cache turned off and device cache turned onInternal hdds:*(2) 1TB WD SATA3 Raptor @ 10k rpm data drives (Raid0)External USB hdd:*(1) 4TB WD SATA3 SE NAS @ 7.2K rpm (backup drive)I saw no significant difference of data xfer speed between internal to externaland vice versa. I believe this is because I reached the limit of my single backupUSB drive performance both read and write.I have two identical backup drives, one for the car and one for the office. Theyare exchanged once per week. I saw no difference in performance between two drives.I was able to (initialize / format / create & delete volumes) while connected tothe external USB dock both in Win and Dos window using Diskpart. I also createdan image of SSD system drive in DOS with USB 3.0 Win PE drivers and UEFI mobo.I docked one star because Win7 identifies the hdd connected to the USB dock bythe Dock's chip# not the actual hdd. It's really no big deal. Crystal diskmarkand WD Lifeguard still see the drive, they just identify it as the USB chip#.I hope this helps:)UPDATE 9/4/14Tested with (2) 2.5" Kingston HyperX 120GB SSDs. One internal, one USB dock.The USB dock performed flawlessly.* GPT / NTFS partitions.* Xferred 30GB of MP4 / AVI movie files.* Performed partitioning / formatting / backup imaging / cloning in DOS, Dos box and Win7.** I was suprised there was very little difference in xfer rates (with MP4 / AVI) between my mechanical hdds and the SSDs. The internal WD 10k raid0 hdds tested with the WD 7.2k NAS USB dock saw ~150MB/s while the SSDs saw ~170MB/s (sustained, not burst). I was expecting more of a difference in favor of the SSDs ... go figure.

My 2010 iMac finally fried and I was told by Apple computer people that it's too old to be fixed. When I turned the thing on, the screen looked like a mix of Space Invaders and an Apple logo. It wouldn't even boot past that first logo screen. I searched the internet relentlessly to try and find a way to move files over to my new computer but after 2 different cables and 4 different start-up modes, nothing worked. That's when I saw a helpful blurp on the interwebs about using your old internal hard drive as an external hard drive. The casing to put the hard drive in was fairly expensive for a good one though, but as I looked at various reviews, I found this amazing toaster-like apparatus! I ripped apart my iMac, which was surprisingly easy to do, pulled out the brain, and dropped it into this toaster and hit the button. BOOM - instant external drive. I got all my files transferred over for about $20 which was way cheaper than the firewire to thunderbolt adaptor and other cables that failed.Mind you, this probably isn't the best solution for long term use of your old hard-drive but it was a life-saver in a pinch. The exterior plastic on this thing is thin so I don't see it lasting long with continued use. The pop-up eject button on the back was a nice little feature though and it works with the laptop sized and regular sized hard drives. Had I not found this item, I hate to think of how much I'd have to pay some zit encrusted, hygiene lacking, basement dwelling, computer "expert" to transfer my files over to a hard-drive for me, all whilst syphoning off my tax forms and other personal files so he can get credit cards in my name and then order all sorts of adult products to fill the emptiness of his relationship-less soul.Anyway, what I mean to say is that if your computer dies and you've never done a back-up (like me) - then this thing is well worth the money!

I have given this dock 1 out of 5 simply because I have 5 fully working sata drives and this dock recognised 1. The others were either not mounted or it stated they were protected disks which they weren't. I have a powered sata to usb connector which recognises every disk but isn't as convenient as this dock would have been. But there was nothing I could do with this device to make it work. There are no driver files and there are no firmware updates on the manufacturer's website. Very disappointed.

Sabrent USB 3 Hard Drive Dock.Comes with leads to connect to laptop/PC. Is supplied with both EU and UK plugs.Accepts both 3.5 and 2.5 inch SATA and SAT2 desktop type hard drives, one at a time.Connects to laptop/PC via USB 3, but you can also use USB 2 ports, although the transfer rate will be slower than if using USB 3.Very simple to use, it’s plug and play, no drivers needed: connect up to laptop/PC and plug dock into power supply, the dock supplies power to the hard drive as well as reading data off it, so no separate power supply is needed. Insert hard drive the right way round and press the on button on unit. The drive in the dock shows up as another drive on your laptop/PC. The contents of the drive to be read can then be accessed. If the drive is dead though (a failed hard drive) then it cannot be read.Working drives can be hot-swapped without causing any problems.I transferred data off my hard drive using the simple copy and paste method and it worked flawlessly. Good product.

I concur with everything that Mr. Coles has typed below, however, as a word of warning I did come unstuck when I first plugged this in as the brand new HDD that I'd purchased for this hadn't been formatted properly, and subsequently, the Docking Station couldn't read it, and it wouldn't show up as a new HDD on my Computer, until that process was completed. My other small problem is that of the 8 other already used HDDs that I have extracted from old machines, this couldn't read 3 of them, one kept revolving with a clicking sound whirring away like mad, but, couldn't be viewed, the other 2 cannot even be formatted to be seen by this machine, so, unless I'm doing something fundamentally wrong, I'm unable to extract data from those, unfortunately. This machine is easy to set up and you get 2 plugs, 1 UK and 1 European, the USB cable is about 9 inches long, and you get a small booklet included to get you started straight away.

I bought this to use with an Asus Prime B350M-A motherboard. I plugged it into one of the onboard USB 3.0 ports and it appeared to be working fine until I actually inserted a hard drive. The drive came up in Windows 10 as unformatted even though it was indeed formatted and full of data. Even worse, when I took the drive out and reconnected it via SATA, I found the data had been corrupted. Luckily, I had it all backed up elsewhere. This issue was repeatable after I tried another hard drive. I updated the device's firmware as advised by the manufacturer, but this did not help. In the end, I found it works flawlessly when plugged into the onboard USB 3.1 port instead. Don't know why.Once working, it is great and I have now been using it for months with no further problems!

Well it worked once. Since then nothing.It powers up appears to spin the disc but the disc doesn't load. It is not the disc at fault as that works fine in another powered connector,i am using a 2015 iMac with Sierra OS loaded and the system overview shows the Sabrent - but as JMicron - unit loaded in the USB 3.0 bus but no disc loaded despite it being inserted and spinning.No such problem with my other connector.Would I recommend it - not to a Mac user despite it being described as suitable for Macs.Another dust gatherer
