4 Bay Hard Drive RAID Enclosure with Cooling Fan for 2.5/3.5" SATA HDD/SSD with USB A/C 3.0＋eSATA Cable, 3.5 Hard Drive Reader Supports 80TB Capacity, 8 RAID Modes, DAS(NO NAS)

This review is for the raid-enabled version of the 4-bay enclosure.Installing 4 8TB WD blue drives went smoothly.The drives took a little bit of convincing to snap into the trays on one side, but they will fit just fine without any modifications.Bonus that full 3.5" hard drives are toolless, so that was a breeze.I used only the non-raid mode, and all four drives appeared over the Esata link to my PC (Esata cable included). Unfortunately, I can't speak to how well the raid modes work.I moved a large file to one of the drives and observed a sequential write speed of around 160MB/s. The same drive connected internally clocked 190MB/s. for many use cases this won't matter.I also had this connected to a PCI Esata card, so that could have been at play as well.I decided this enclosure wasn't for me due to the level of noise that comes from the fan. I wouldn't call it loud, but this was going in my living room and I am super picky about having it silent while watching movies. if I can hear it at all from 10 ft away, it's a no-go for me. My PC is way overbuilt for absolute silence, and I just can't expect that from, likely any external drive enclosure. If it were a bit quiter It might have worked for me.I'm not even knocking off a star because it is actually is a good value for a DAS and is fairly quiet, just not quiet enough for my use case.

I think this is a good value. I loaded it up with 4 drives and changed the dip switches and this is where the missing star comes in. There are no instructions on how to operate this thing and there are also no videos on youtube etc explaining it. I honestly cannot remember how you do it now, I believe it is hold a button down while plugging in the power to get it to change modes. It comes in JBOD mode. I emailed the customer service and they emailed me back with the instructions in just a few hours so if i could give them 4.5 stars I would. Its not that hard to throw an extra paragraph in the little instruction manual that comes with it.It's not noisy for me like others are complaining, I can't even hear it.The one thing I haven't tested is it's ability to restore a bad disk. I am about to buy another one of these and I plan on doing some experiments with it by failing a hard drive and plugging a new drive in to go through the process of a rebuild.I am about to install the new one in my office so data integrity is very important.

Very happy with this unit. Assembled all my surplus Sata drives into it and we now have 3.5 TB of storage. The RAID hardware can configure several ways.

The unit arrived and was set up within a only a bit of trouble. My drives fit in without the modifications listed on this Amazon page. It took some patience to fit the first drive. Once it was in, the drive was very secure. I suggest you work with the tray without modification to keep the toolless operation. Screws and a driver are included if needed.Once I got it running and visible on my computer I plugged it into the ESATA port on my NAS and it was immediately recognized. This gives me an additional 12TB of space. I am using reconditioned server drives, so redundancy is required.The main problems is the poor manual. It is very small making it hard to read the tiny font and diagrams. Take a photo of the page and read it on your phone.The instructions are insufficient for proper set up. The QR code on the back is labeled "software" but no software is required. Instead the QR code leads to instructions to complete the RAID setup. All that is required is a simple reset procedure but you have to know to do that.Once I did the reset, the device worked just fine.Contrary to the promotions on this Amazon page, is far too noisy to leave in an occupied room. The two inch fan is very loud. Fortunately I have a isolated server space where my NAS is located.Even though it is an attractive price, it far too loud to be not suitable for apartment use. DO NOT buy this for use in your family room for video streaming.

Super easy to mount drives! No hardware needed!At first I couldn’t figure out how to get the enclosure to switch to RAID mode (I’m using RAID5) but once I read the online instruction manual (the included instruction manual is very small and I couldn’t read it very well), and noticed the fact that the reset button needs to be depressed WHILE THE UNIT IS BEING POWERED UP, it worked perfectly!Meanwhile, I had sent an email to their support dept. and they got back to me with the same advice within about 12 hours. Pretty great, especially considering the great price!

It took me several hours to get the drives to read and partition. The setup is a struggle. It appears to be working well. I initially didn't install the drives as a raid to get them formatted. I don't know if I had that it would have gone faster. They were 4 drives I had from a buffalo nas that died. The instructions are very small but if you go to the website you can download a PDF although enlarging that blurred out all the images but at least the text is readable.
