4 Bay RAID Hard Drive Enclosure, Yottamaster Gaming-grade RGB 4 Bay RAID Enclosure Support RAID 0/1/3/5/10/JBOD(SPAN)/PM, Aluminum 4 Bay HDD Enclosure for 3.5"/2.5" HDD/SSDs - [DF4RU3]

I have bought this unit mainly to have a nice datastore in my home network. The unit has been equipped with 2 WD RED PRO 8 TB in RAID 1 mode and been attached to a Raspberry Pi 4 in order to serve as a backup station for my computers. The design is very stylish and fairly elegant. Trays are well build but once the disk are inserted you have to pull them with care in order not to brake the plastic parts holding the drives. RGB fan color is a plus but it would have been nice to control the colors (or switch it off) as well as step down its RPM, as its quite loud to my taste. The unit fits into a 10" rack, but mind you, you need angular connectors for both data and power in order to fit it in.Overall I am very satisfied with the purchase.

Really impressed with this device. Loaded with 5 x 2TB drives and configured as RAID 5 in no time.Fan is very quiet and throws a nice coloured pattern out the back of the unit! Drive drawers are plastic and could break if not handled well, but I don't think I will be pulling these in and out that often, so not a problem. Would recommend this unit.

Only had this a couple of days but it works very well. The only downer is the fan never stops and is a bit noisy.I have four SSD drives in it so they don't get that hot, I tried disconnecting the fan which obviously makes this silent but was a bit worried about the built-in power supply with no cooling, the drive temperature went to 7C above ambient.So did my old trick of getting a slim quiet fan and also fitted a 12v to 5v power supply in line, eg running the 12v fan at 5v. The hard drives are back at 3C above ambient (as they were with original fan) happy days and the unit is virtually silent.Note the fan never turns off, so I have the mains disconnect when I power off my PC. Powering the enclosure up at the same time as the PC is not a problem as Windows always sees the drives.If the drive powered the fan off or adjusted it's speed depending on temperature this would have been 5 stars, it is takes a bit of work but can be made almost perfect.

But the fan (despite the description) is not that quiet, and nor does it spin down when the disks aren't under operation. It's louder than my 6 corsair fan cooled PC. So minus one star for each point, since this was the influencing factor behind my purchase. On the plus side it does look nice on the desk and the HDDs are easy to install, fix into place and slot the trays into the chassis. So if you don't mind the extra fan noise then this is an excellent purchase, the RGB feature of the fan is a nice touch to lighten up the desk environment without being intrusive or distracting.

After reading through the blurb and getting a little confused, I went for it any way. Basically, if you want to install a brand-spanking new HDD, you'll need to format it once you've fitted it in a caddy drawer. If, like me, you want to add pre-used drives with data already in them, just screw them into one of the drawers, and you're ready to go. Works like a charm. I have 3 drives in this 5 drawer, a total of 26 TBs. The read/write speed is just fine, with very little start up lag. It's a solid piece of kit, and worth the price, IMO. 5 Stars.

I bought this literally on looks alone. It can support up to 80tbs and I am on 12 using 4tb Drives, so can go up to 5x16 which should be a way off.When you plug this in Windows it recognises the drives separately in disk management and all that is needed is initialization. I then configured storage sense with parity as I wanted redundancy with expansion ability (i.e. to add larger to the array when funds permitted). They do an array version of this also. This worked straight out of the box and the only problem was the supplied screws didn't fit (too small and short), so I just pushed the drives in loose-not professional but heigh ho.

Wanted to update this a few years down the line, it failed after two years.

Pros = Well-built, and robust, easy to use, great finishCons = It takes, what seems to feel like forever, to initialize. I regularly access small files on the drives throughout the day and have to wait for it to initialize every time I access a file if it powers down; it is tortureConclusion = If it was not for this, I would rate it a 5, but this issue ruins the whole experience.
