    Pretty Good USB 3.2 Gen2x1 (10Gbps) to SATA 6Gbps Dock
    5 Stars
    Pretty Good USB 3.2 Gen2x1 (10Gbps) to SATA 6Gbps Dock
    The SDOCK2U313 uses an ASMedia ASM1352R chip, which is one of the best USB 3.2 Gen 2x1 to SATA chips currently available. The ASM1352R supports hardware RAID0 (Strip), RAID1 (Mirror), JBOD, and Span (BIG) but Startech states they have not made them available in this product. You will need to use software for that, no biggie. SMART, UASP, 4Kn, and TRIM are supported.The SDOCK2U313 advertises it can operate at Full Speed USB 1.0 (12Mbps), High Speed USB 2.0 (480Mbps), SuperSpeed (5Gbps), and at SuperSpeed+ (10Gbps). Having 10Gbps capability is a benefit over 5Gbps because 5Gbps only has an effective throughput of 500 MB/s and 10Gbps has an effective throughput of 1200 GB/s. SATA III has an effective throughput of 600 MB/s and can saturate 5Gbps. Essentially, a faster SATA dock will not be possible and this will be the last SATA dock you will ever need, which is nice (unless you want to dabble in SAS drives).Linux lsusb lists this device as bInterfaceProtocol = 98 and Driver=uas, which verifies that UASP can be used.The included USB 3.0 A to B cable oddly isn't Startech branded and only weighs 1.50 oz, with a diameter of 4.9 mm. A Startech branded USB 3.0 A to B cable of the same length weighs 1.85 oz, with a diameter of 5.5 mm, implying better conductors and shielding. According to the Startech website, both USB cables are only rated to 5 Gbps. If you are wanting to connect this dock to a USB C or Thunderbolt port, I would recommend the Startech 1m USB C to USB B cable (10Gbps) or Startech 2m USB C to USB B cable (5Gbps) to ensure the best performance from this dock. I personally would like to see a better cable included but this one will work.Older designs of this dock had separate power buttons for each drive. This newer design only has a single power button. Makes no difference to me but if you are anal-retentive, you might not like that.FYSA: According to the manual, "When you have two drives inserted in the docking station and you remove one of the drives, the other drive temporarily disconnects as well."

    Verified Purchase
    This is our second StarTech product. They all work great. USB 3.1 and 3.0 connections are very stable. StarTech quality over the last 4 years has solidified our confidence in their solutions, so we plan to continue to purchase their stuff. Our other product from StarTech was their External Drive Enclosure for 2-HDD USB 3.0 which also perform very well.

    This unit replaced a similar inferior product by Thermaltake Duet HDD Docking Station which kept getting disconnected and causing file system errors.

If you are wanting to connect this dock to a USB C or Thunderbolt port, I would recommend the [[ASIN:B00YEDRSRM Startech 1m USB C to USB B cable (10Gbps)]] or [[ASIN:B0727R2MDY Startech 2m USB C to USB B cable (5Gbps)]] to ensure the best performance from this dock. I personally would like to see a better cable included but this one will work.

    Older designs of this dock had separate power buttons for each drive. This newer design only has a single power button. Makes no difference to me but if you are anal-retentive, you might not like that.

    FYSA: According to the manual, "When you have two drives inserted in the docking station and you remove one of the drives, the other drive temporarily disconnects as well."

    3.0 out of 5 stars Expect better build quality for the cost

    First I ordered a used one in "Good" condition – it went up in smoke as soon as I turned it on. Got a new unit and it's working better. However, I had a disk inserted in slot 2 from which I was copying data, and in the meantime inserted a disk into slot 1. This caused the disk in slot 2 to abruptly re-attach to my system which interrupted the copy. I would expect it to handle hot-swapping better. I'm get about 23 MB/sec copying from an old laptop SSD rated for 400+ MB/sec but I don't know what the bottleneck is.

    5.0 out of 5 stars Saved what I thought was lost

    I found it very useful in consolidating drives. The ability to power much larger drives is very useful. I have managed to consolidate five drives onto a new NAS. I have also reused three of those drives, saving enough money to cover the cost of the dock.

    I has a laptop that literally caught fire. I thought the drive was burned up. Turned out I was able to retrieve the files after scrapping the remains of the laptop. Without the dock, I am not sure I could have recovered the files

    1.0 out of 5 stars If you're looking for a reliable dock--look elsewhere

    This is the most unreliable USB dock I've ever used. I've emailed back and forth to tech support and we haven't been able to come to any conclusion as to what's going on with it. When I have two drives in it and I need to transfer data or perform a clone, three out of four times, it will randomly disconnect from the computer--causing whatever application I'm running to crash. I thought that it might be my computer, so I tried the same procedures on another workstation and had the same problem. I've connected up another brand dock to my system and had it perform the same tasks without issue. If you're looking for a reliable dock--look elsewhere.

    I bought this to connect two 6TB sata drives to a small gigabyte Brix ultra compact computer. Data transfers are very fast! If you don't need the RAID protection a NAS can offer - this is a great alternative to get lots of space hooked up to small machines.

    5.0 out of 5 stars Excellent dual drive dock
    Reviewed in Canada on December 23, 2018
    Verified Purchase
    This dual dock works as advertised, with super quick transfers. It doesn't look as "cheap" in person as the photos seem to show. It was one of the things that made me second guess purchasing it, but was pleasantly surprised once I did receive it. Quite solid, and doesn't transfer the vibrations of connected hard disk drives to the table as much as a previous single drive dock I had did. The power connector at the back seems a little bit flimsy, as at least one other reviewer mentioned, but I don't plan on moving this dock around much, so it shouldn't be an issue.

    All my HDD Docking Stations are from StarTech, simply because they never fail and they never break!
    A quality product from a very good Brand with high Service for its Customers.
    They last for years, I only have to buy new ones when the Hard Disk Capacity outgrows the capacity of the Docking Station. The old Docking Station is then easily sold second hand.

    Ottimo prodotto. Funziona egregiamente e non ha dato problemi di sorta nei pochi giorni durante i quali l'ho utilizzato.

    Sarebbe arrivato anche un paio di giorni prima rispetto alla data prevista se non fosse che GLS, come al solito, fa finta di non conoscere il mio indirizzo. Non metto la quinta stella per questo motivo. Sono dovuto andare di persona presso l'ufficio locale di GLS per ritirare a mano il pacco dopo tre tentativi andati a vuoto. Francamente sono stufo, da utente Prime, di avere continui disguidi grazie alla pessima professionalità di GLS.

    3.0 out of 5 stars Does not work on my dell g5 5500 RTX 2060 and windows 10 (but does on older windows 7 machine).

    Well, I did contact support, to find out that I should have tested in on 2 machines. I would say that if one is having the same machine as in title, with windows 10, the drives never stay connected long and do not allow any activity by user. Often not showing at all. any port.

    Tested on old Dell xps17 laptop, with the real OS windows 7, and it works fine there.. Since I made this review, I put a middle range starring rating (although chat support was effective), this might be a review of the Dell laptop USB port system.. I will try to update.. with new information.
