OWC Pro Reviews

Impressive Design

By Stephen
Rated 5 out of 5
Date: 2022-01-23

Beautiful design, all-metal construction, easy to install the hard drive. I like that the hard drive mount screws have rubber grommets for noise reduction and shock absorption. I've purchased cheaper hard drive enclosures, but never again after buying this one. You get what you pay for.

Solid Machine

Works fully as advertised. Solid machine, Small CONS: fan is louder than I'd like (as noted by other reviewer). The Thunderbolt 3 cable is too short to be realistically useful.

Using this with a 1TB WD Black drive as a backup for my Synology NAS, connected by eSATA. Well packaged unit complete with cables for all 3 interfaces, plus a power brick and cord. Compact metal enclosure, no fan so no noise. Nice addition to my system and as always great service and shipping from B&H.

Enclosure does not work as described.

Very disappointed. I ordered this to use with a Western Digital 8TB HD. It does NOT work. Spoke with OWC. Their answer was I guess our enclosure is not compatible with that drive. The OWC enclosure specs say it supports drives much larger, so the size is not an issue, but they seem to have no idea of what hard drives they support. before purchasing the 8Tb HD, I called OWC and specifically asked them if the HD was supported. They said 'yes'. No word of but some drives will not work. This 8Tb HD works fine if I connect it internally.

great quality,fits 18 tb ultrastar great.

No longer working

Worked fine for a year. About a month ago it started disconnecting. It was once a week, then once a day, then it lasted about 30 minutes, and now it won't connect at all. Tried different hard drives, ports, cables, etc. with no luck. I recommend getting something else.

LOUD!

The drive works as advertised; however, it's LOUD on all accounts. The fan noise is loud when the drive is idle. In addition, it's even louder when the drive is working and being accessed. I would not have purchased this if I knew how loud it is!

Good Quality Enclosure

Quality of enclosure seems top-notch and it was available with the hard-to find eSATA port. I bought it to use with a 4 TB WD black HD to add capacity to my DirecTV DVR. Unfortunately It didn’t work well (picture hangs up and pixelates a lot) but it’s a HD compatibility issue with the DirecTV box, not the OWC enclosure. It did the same thing when I mounted the HD internally. I’ll use enclosure and HD for backup with my desktop.

Can two separate computers access the files on the RAID at once?
Asked by: Abe
To expand on previous answer: yes, but only if you connect the enclosure to one host computer and share volumes/folders from the host (create network shares). Then, of course, those volumes/folders are shared with any computer that has rights to them, within the limits of the host's operating system.

Does this device support RAID 1 for two HDs with different capacities? Specifically, will it support a Western Digital 5TB WD50EZRZ and a 6TB WD60PURZ in a 5TB RAID 1 configuration?
Asked by: Keith
Technically it will work, but you will only get the lesser of two capacities. In this case, you would lose 1TB. This is the same with any RAID device, unless specifically stated otherwise with a unique software RAID such as "beyond RAID".

How does this device compare to the Akitio ...

How does this device compare to the Akitio Thunder 3 RAID Station? 1.) Power delivery for the Akitio device is 27W— what is it for the OWC device? 2.) Have any of the chipsets been changed— from what to what? 3.) Is the OWC RAID controller compatible with drives from the Akitio RAID controller? 4.) Would you recommend an Akitio RAID Station owner buy the OWC Pro Dock— as a second enclosure— or would it make more sense to buy a duplicate Akitio?
Asked by: Demian
It is essentially identical, but the firmware is much newer, I would not attempt to swap drives from an Akitio unit to an OWC unit unless you are willing to reformat the disks.

How does this Mercury Elite Pro Dock compare to a new "20TB G-Raid with Thunderbolt 3". I'm planning to put 10TB Gold drives in the OWC. OWC claims to have a higher MB/s than WD. Any experience? What about fan sound? I just tested a G-Raid and was pretty quiet.
Asked by: Giuseppe
The numbers are accurate in my testing. The fan is not silent though, it has to move too much air to properly cool the drives.
