Yottamaster10Gbps 5 Bay USB C Hard Drive Enclosure Daisy Chain, Type-C External HDD Enclosure Support 2.5" & 3.5" SATA HDD/SSD up to 5X18TB, Non-RAID DAS Support 270TB Storage Expansion [FS5C3]

With no drives attached, this idles at 3w, and roughly 3w per additional idle drive attached, so power consumption is good.80mm rear fan is very quiet but does have a slight hum that you can hear from close by. You could swap it for a Noctua if you wanted, its just screwed in, and you can access the back of the unit just by unscrewing the rear screws with a torx bit.Its detected and ran without issue, a whole variety of 2.5 and 3.5 mechanical drives I threw at it, but does seem to be picky with SSDs. Your mileage might vary.

Bought a pair of these (which I'm about to return) to replace some Orico enclosures that only suffer from bad airflow. Physically these are very nice, the cooling is a lot better, and the (no key) locking bays feel nice and secure. Build quality is really nice, and they *feel* very good.Sadly they are unusable. Despite anything you may find online there is no way to turn off the sleep timer on these (non-RAID) - directly contacting Yottamaster had a reply from them stating that they do not support that option, and the official software / firmware for this does nothing.Additionally plugging known good drives (Toshiba 10tb) in has resulted in generating actual SMART disk errors on most of them (even to the point of Linux marking them as read-only) - this was not related to the drives being awake or otherwise, and placing them back in the Orico bays (and a new Orico bay that I just bought for data migration) has resulted in no further errors (where they were gaining up to 20 errors per day!!)If they sort out these issues then I really like them - the features would make them very useful if they fix these issues - but I know I won't be buying from the brand again as a result of this...

Avoid at all costs. As others have said - used as a straightforward DAS and once under load for a while it will corrupt at least one drive requiring a reformat and loss of data. Thus useless for Plex etc.Return window is only 90 days and customer service is a joke - email to a Chinese rep who stopped replying after the first two emails - have been trying every couple of days since but don’t hold out hope.Now an expensive paperweight and shelling out for a more reputable brand - should have done that it the first place.Choose something else.

The product looks nice, however I couldn't open 3 of the 5 slots. Therefore I will be returning it.

I used this as a JBOD device for Proxmox to expand a current cluster, absolutely rubbish, drives seems to constantly be getting corrupted while in this device. Initially thought it was the drives however I have since put them in a different device (Dedicated NAS) and had no issues with them since.~I highly suggest you avoid if the data you are putting on is important.
