USB 3.1 Type C 8 Bay 3.5-inch Hard Drive Enclosure - USB 3.1 Gen 2 10Gbps Support UASP/S.M.A.R.T / 12TB Hard Drive (H82-SU31C)

I got this to declutter the shelf where my home media server lives. Instead of having 4 USB drives sitting on the shelf I now have this one box connected via USB-C to a mini-PC with no internal storage beyond an NVMe SSD.It's very quick and works perfectly well but does NOT support hardware RAID. One could make a software RAID using Windows 10/11 Professional, note that the specs state this enclosure does not work with Linux. I have not tested it with Linux.The sync button is interesting. With sync turned on the enclosure powers up and down with the computer to which it is attached but will not recover from a power failure, that requires a human intervention to push the power button on the front.I cannot really fault this enclosure, for the price it is a great deal.

I got my original boxes that were USB 2.0 and eSATA and have used them non-stop for over 10 years... they are simple to use but required a esata card with port multiplier to use, which made them a bit complicated to set up. The only situation I had for all those years was a power supply for one that died and had to be replaced. When COVID hit, one of the boxes died and I replaced it with a newer esata/USB 3.0 model but it was used as all new stock were impossible to find. And 2 years later, that is the box that has now died on me, but it is possible that it's due to power surges and such as these last few months, the city has had a lot of problems due to many storms and such, and it may have also damaged my UPS that should have prevented damage to my devices including these boxes... I'll never know.But that said, this box is replacing that other one (and is the exact same) and I will hope that it will last as long as my other older boxes that are still going strong so far.These boxes are simple to use, with only one annoyance of needing a small handle to be installed on the drives. The fans are very silent and aside the situation that requires me to get a replacement, have been very solid and working very well for a lot of year.In time I will most probably need to replace them for a more modern setup as the old boxes are supposedly limited to 4TB drives (while the newer ones are able to use much larger drives) and will switch to USB 3.0 (or better) and leave the eSATA in the past so to prevent the headaches I've had due to that.I almost went with the 8-bay boxes, but reviews have been alarming in reference to the number of issues that people have had compared to the 4-bay ones, so I'll have to see when the time comes.But for now, these boxes have been great, have been through constant use (24/7) and I've enjoyed them greatly, and for a price range that left all competition far behind.

The unit itself seems good BUT the inserts for 2.5" disk are special and expensive. Each is 11.00 odd so that needs to taken into account when you buy

Good for having 8 drives connected to you pc via 1 cable. Temps are acceptable with high fan setting.performance is the same if you had your hdd connected to sata port.moving files from one drive to another inside the enclosure sometimes drops after 100GB or so with an error.Causes longer bios time, my system goes to 106 s bios time.

Runs way too hot and fan noise is unbearable.Sitting on a wooden desk out of sunlight and well away from any heating source at idle WD 8TB Red NAS drives are cooking at over 60 Deg C.Very poor airflow design inside the chassis leads to the 80mm fan running like the radiator fan on a car on a hot dayOther than that, great transfer speeds even in RAID 1, easily achieves 150Mb/Sec for write when transferring large files. Then it gets hot and bothered after a couple of minutes and fan kicks in and never stops until powered down.
