OWC Drive Dock USB-C Dual Drive Bay Solution, USB 3.1 Gen 2, for Mac and PC, (OWCTCDRVDCK)

Recommend before purchasing to have/get a PCI-E USB-C card (if your system doesn't have one built in) from a reputable company (the card I use is from SONNETT). If anyone will be using a Thunderbolt connection, be sure to go to the OWC website and download their latest firmware and drivers before using. After setting up and before you transfer, be sure to format your empty drive first and then go to your DISK MANAGEMENT and enable "Write Cache" for performance (you'll have to use your OS to eject the disk if you check this feature). Depending on what format disk you're using (I.E. - HDD, SATA SSD) you'll get close to 980mb. Just be aware that this unit does not do offline cloning. It has to be operated with your respective OS. If anyone is using HDD, I suggest a higher capacity drive (min 7200rpm/265mb cache). SATA SSD's are a better choice. This drive is perfect for people who have laptops and for those who would like to have a clean and uncluttered workspace. Solid construction and design. Worked like a charm for me and didn't have to deal with the hassle of installing the disk in an external case.

So far so good. Working well now will have to see how it goes over time.

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.

After going through two of the cheaper $30 docks I decided to get this one and now I'm wondering why I didn't get this sooner. Build quality is fantastic. It just feels professional to use. It is also well thought out. Cheaper units have a single on/off button. This has a main on/off switch AND two additional on/off buttons for the bays. This means you do not need to power down both drives to remove one. For some reason OWC is the only brand with the smarts to build the power supply into the dock. The power bricks and DC connectors on the cheaper units always annoyed me. It just seems like an obvious thing to do given how hollow they are. Having a simple two prong power cord makes cable management and plugging into a power strip so easy. Speaking of, the included power cord is comically short. Like three feet. I needed a 10ft long cable for my setup anyways though, so the fact it was easy to swap out with another standard two prong cord is a big plus. This drive bay does not have a native cloning function but I actually prefer this. I would never blindly trust the cheaper units to clone drives. I'd much rather use software that will actually tell me what it is going to do. I was always nervous about accidentally hitting the clone button and wiping data. With the OWC I don't have to worry. Overall completely satisfied!

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.

I replaced a many year old one of these because one slot died. I use it to save backups of both SSDs and Hard drives. It’s easy to use and pretty quick. It will work on 2 slots at the same time. Came with a usb-c cable.

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.

Not a long term review, and I'll update if any issues.... Bought primarily to replace a slow HDD dock, and it is certainly quick with USB 3.2 Gen 2, it can transfer @ upto 10mbps. Another useful feature was the ability to switch off each drive separately, a royal pain normally if you have 2 HDDs mounted and have to switch the whole unit off in almost all other docks to remove/swap one disk. Quality, OK it is not cheap (much like Apple kit), but you get what you pay for 'generally' and it looks very well made, they have gone way further than what is needed to do the job. Just one thing that most dual docks have is the offline clone facility, it does not have this, it wasn't something I wanted, especially after 'someone who will remain nameless' hit the button once on my other dock and caused me a lot of grief. So, to sum up, built like a tank, great quality, this company care about making a solid product and it shows. Just look at the thickness of the aluminium casing in the second photo. Also, if you are an apple 'fanboy' and I'm a recent convert after many years with Windows PCs, It rocks next to my Mac Studio.

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.

Nach einer katastrophalen Erfahrung mit einer Dualschacht Dockingstation von RSHTECH (Modell DE-RSH-DS02), die reihenweise die Dateisysteme von Festplatten korrumpiert hat, bin ich auf dieses Juwel der Firma OWC gestoßen. Die Station ist sehr robust, wertig verarbeitet und nimmt 3,5er und 2,5er SATA HDDs sowie SSDs auf. Das Netzteil ist im Gehäuse integriert, weswegen dieses schon etwas größer ausfällt. Beide Schächte verfügen über separate Geräteschalter und werkeln unabhängig mit Asmedia ASM1151 USB-SATA Bridges und Labs Vl820 USB 3.1.Gen 2 (10 gbps) Controller. Anbei ein Crystalmark Performance Benchmark der OWC Dockingstation mit einer Samsung SSD 870 EVO angeschlossen an einem 10 Gb/s USB-PC-Port. Die SSD wird von Samsung mit max. 560 MB/s Lese-, 530 MB/s Schreibgeschwindigkeit beworben ... da geht schon was!!! :-) Die OWC Dockingstation ist jetzt seit über 6 Wochen hier im täglichen Einsatz und versieht rocksolide ihre Funktion. Dafür vergebe ich die volle Punktzahl und kann das Produkt sehr empfehlen.

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.
