Drive Dock USB 10Gb/s Dual Bay SATA Drive Solution | Access two 2.5/3.5-inch SATA drives via USB-C or USB-A - Internal power with independent power switches - For Mac and PC

Replaced similar dock that was eSATA. USB C was just as fast as native eSATA but with better ability to disconnect and reconnect. After reading reviews, I decided on the OWC because one of my backup drives is a 10TB. It was immediately recognized. My eSATA dock would only recognize one drive at a time. This OWC recognizes both, even though it connects through just one USB C cable. I recommend Tripp Lite cables. This unit came with a cable but I used a 3'3" Tripp Lite. I am using two SATA HDDs for backup of internal NVME SSDs. I did a file copy from one HDD in the dock to the other HDD in the dock, and even though the unit connects to my 4 port card with only one USB C cable, I get FULL SPEED transfer between the two drives! I have not tested the clone function but I could not be happier. I upgraded from an older USB 3.0 dock and 3.1 has no speed limits for your HDDs. WORTH the extra $ over the cheaper units on Amazon. ALSO: I saw a review that the power buttons on top had a cheap feel. I disagree. I think they are fine. Out of all the docks I have owned, THIS one has the power and data ports on the SIDE, NOT the back, so the orientation of the "DRIVE 1" AND "DRIVE 2" indicators is sideways. I wish I could twist them to the proper orientation, but that would not even subtract a star.

I've been wanting to implement an offline backup rotation of my NAS data for a while. I was looking for a clean USB Drive solution where I could easily plug in a drive, have the backup run, and then store it back away when done. Most USB drive adapters can do this no problem, but I did want something a little more robust, cleaner looking, with modern USB connections. This OWC Dual Drive bay device fit the bill perfectly. To the point of cleaner looking, I have a personal aversion to power bricks; I rather the device be larger and use a conventional power cable than have to keep track of power brick with a quasi-proprietary connector. If this is "a thing" for you, in early 2022 this device is the only option available that I could find to meet those requirements. This ticks a lot of boxes, but also is possibly the most expensive option at just under $100. So far so good, it's working great for me so far, but will update this review later if anything changes. Side note, it may be my monitor, but on the Amazon product screens the device looks white in color, in reality it's a sparkly metallic gray. I experienced the same color differences with Unifi network devices. TL:DR Pros: +no external power adapter, simple power cord +USB-C +works on my Synology NAS using the USB Copy app. Also worked perfect on my Windows 10 PC. +materials: metal and build quality seem solid +clean looking Cons: -kind of pricey

This is a serious upgrade from my old Orico HDD dock / duplicator. Here's what I like about the OWC dock: This feels quite sturdy compared to many others I've used. Each HDD comnection is on a separate plane with a separate power button. The others I've used have the HDD docks on the same connection. With my old one, if I had a drive connected and I inserted another drive, it would disconnect the already connected drive. This meant I couldn't insert a drive while the other was working. With this OWC dock, I can insert a second drive without interruptions. The lights are very visible and informative. If a drive is inserted but not on, the light will be off. Turn the plane on and the number lights up blue. When the HDD is actively operating, it blinks red and blue. And when the drive is unmounted, it "snores" in blue. Press and hold the power button to power down the drive, and then it won't be spinning when you pull it out. There doesn't seem to be an offline duplication tool, which is fine. I had my Orico docks for a long time, and I've only used the duplicator once. I still have one of my Orico docks for duplication if needed. As far as speed goes, it's fine. Speed often depends on the drive. My WD RED drives are slower than my WD BLACK drives. But it's plenty fast enough for the job. Time will tell regarding reliability.

For reference, I sent back a cheapo dual dock that blatantly mischaracterized its capabilities. Be aware that the cheap units DO NOT support hotplug. If you pull or add a drive, the other will be unmounted momentarily. The performance of the cheap unit I had was also horrendous. Good with one drive, but barely better than USB 2 with both. I mean, that's the whole point. The OCW unit however is premium. Each bay is 100% independent. I used it to zero out roughly 30 drives (3.5 and 2.5, HDD and SSD) and it worked flawlessly, both drives operating at full speed. It takes a lot for me to spend 3x on something that looks equivalent, but trust me-- this is in a different league. CONS: * The buttons are fiddly and instructions are not super clear on how to power up / down each bay. It can look powered down but not be, you have to hold the button longer-- * It's expensive. * Provided cables are comically short. Had to buy my own. PROS: * It's legit. No hardware shortcuts. * Looks great, has some weight to it. TLDR; Don't waste your time with the no-name junk. This thing is quality and it's USB 3.1 gen 2, you won't need a new dock until SATA is phased out.

Everything OWC is built very well and some of their products I have had for years and all are still working well. They might cost a little more than the competition but we'll worth the additional cost if longevity is a factor.

Not much to say other than I’m glad I bought it, and it’s a great solution if you have bare drives. Works great with all my Macs. Plug and play.

pay the extra - this is the best dock i've had so far (and i've had quite a few). the orientation of the controls takes a bit of getting used to and it's a bit larger than most other dual drive docks, but the build quality is great, really solid. yes the buttons are a bit wobbly, but not as bad as some of these reviews suggest - it's not like it won't register when you press on them, or that your finger is going to completely slip to one side of the button. speed is excellent, it is definitely faster than regular usb. currently using 10 TB wd reds in it, but i've tried an 18TB wd drive (shucked from an easystore) and that worked fine as well. using it on a 2020 imac, matches up very well looks-wise, and haven't had a single issue with it so far. get it!

Surprisingly bad piece of equipment. Highly unusual for OWC. Bought 1 and exchanged for another due to problems....thinking it would solve the problems I saw....which....happened all over again. Note that I used the OWC supplied cable in all my testing of the OWC unit. Issues: 1) It took almost 2 minutes to read a 2TB HDD on a USB 10 GBPS port vs less than 2 seconds using an USB 3.0 HDD dual drive by Newertech on the same 3.2 GBPS port. 2) Black Magic crashed when trying to do a speed test on this drive while in the OWC. 3) On the OWC I was unable to eject (a software eject) the drive on my MAC - I had to force eject. No problem on the old NewerTech. 4) OWC would read the drive in question but would not format via Disk Utility - said there was an error. Said there was an error. Put same drive in the NewerTech and it read it just fine, reformatted as well via Disk Utility. Going to test this against a USB 3.2 Startech - which BTW failed as well. Writes never exceeded 10MB/S....Apparently the MAC M4 Mini does not like USB 3.2 docks - but it does like USB 3 dual docks...since my 4th purchase (one by SSK)...worked as per spec. So I recommend sticking with the older tech USB 3 models since they work.

E molto solido, e fatto in allumino la parte inferiore e di un buon spessore, la parte superiore e in plastica. Ho apprezzato moltissimo la possibilità di abilitare o disabilitare uno alla volta le singolo Drive Bay. Si abbina bene al mio Mac Studio.

Très pratique et fonctionne exactement comme ce à quoi je m'attendais. Le fait de pouvoir changer uniquement un HDD (ou SSD) sans éjecter l'autre est vraiment pratique.

I had bought another dock a Sabrent with the ASMedia 1352R which has to reload both drives if one is pulled out taking up to 10-30 seconds or never re-initializing, this for me completely ruined my productivity sorting out 32-35 hard drives of varying sizes and capacity. This thing while not perfect is miles better having 2 independent ASMedia 1351 Chips one of each drive and a VL820 USB 3.1 Gen 2 bridge to tie them both together. The speeds are ALMOST SATA 3 6-Gbps, not all the way there but compared to the other dock I had the speed when running benchmarks drop to 200MB/s or less while this OWC dock sustains around 450-500 while bench-marking two SSD drives at the same time. I tested Two 128GB MLC drives and one 240GB MLC in a few benchmarks simultaneously like ATTO and Crystal disk mark, it performed very well and could not ask for much more. OWC like both struggles with Mixed random Read/Write not getting up to true Sata III speed, Still more consistent than the Sebrent but it's almost on point for Sequential Read/Write with just under the max 550 Read/Write. This thing is well build enough a far cry from the other dock feeling heavy enough not to get pulled off my desk and not having any catching issues with my hard drives getting stuck on the flaps. The two power on/off buttons while nice are a bit cheap feeling a shame since other wise this thing is built well enough inside and out, having good quality SMD aluminum caps inside and a decent looking PCB, the PSU on the other hand is nothing special, just a generic 65 watt PSU more than enough to power both drives with no problems. You may want to get a little desk fan or rig a pc fan to keep things cool over long sessions of use. If I had to sum up how I feel using this thing it's, it works very well, has some minor problems with QC my aluminum has a pitted defect, but overall it's miles better than anything else out there, I'd like to see better but this is the best right now. So if you need a dock and have a lot of hard drives or SSD's to work with get this dock, you will not be disappointed with the overall performance. After using this dock I would never go back to cheap docks that just don't work right, get one if you have a lot of hard drives or need speeds that are overall consistent on both USB-C 10-Gigabit and usable on 5-Gigabit USB 3.0. with both drives copy/reading constantly.

Wer über einen USB 3.2 Gen2-Anschluß vom Mainboard verfügt, sollte umsteigen! Die Daten werden rasend schnell übertragen und das spart Zeit. Im Vergleich zu den 30 Euro-Geräten ein echter Vorteil! Würde ich jederzeit wieder kaufen. Achtung: Klonen von HDD's geht nicht!

Compared to the 5 bay Orico Drive, this OWC unit is twice as fast and does not sleep the HDDs. On Mac Time Machine, have no issues using the OWC Drive Dock but sometimes have issues with the 5 bay Orico Drive, when the HDDs are sleeping too long. The other good thing is the OWC Drive Dock has two bays, with its own power button for each HDD bay. The issue with 5 bay Orico Drive, is when you insert or remove one drive from the HDD bay, it will disconnect and reconnect all drives, making the Mac show "Drive was removed improperly" error.
