5 Bay Hard Drive Enclosure, Aluminum USB C 3.5" HDD Enclosure for 3.5 & 2.5 Inch SATA HDD/SSD, Support 90TB(5x18TB) Direct Attached Storage DAS, Non-RAID [PS500C3]

Yottamaster 5 Bay 2.5 & 3.5 Inch SATA Hard Drive Enclosure, 6Gbps USB C HDD/SSD Enclosure with Fan, Up to 80TB(5x16TB) Direct Attached Storage (DAS) for Data Backup NAS Expansion [PS500C3] Large DAS enclosure that holds up to 5x 2.5/3.5 SATA hard drives. Thick brushed aluminum outside casing. As others have indicated, the front door is a little bit on the light weight side. It has a plastic frame with a very thin aluminum cover. But then again, you only need to open it when you are swapping or installing drives. So far, the preinstalled 80mm fan has been keeping the hard drives cool. Even though I only fire it on for short time periods to backup data to the unit and access stored data. It does not run constantly, so my temperature readings may not be the same as a User that has it running all the time or extended time periods. Fan is quite at only 35 to 40 decibels. Brand new hard drives will need to be formatted before installing it in the DAS enclosure. I was able to install two drives that had data stored on them with no issues with accessing the data after installation. Fine and coarse mounting screws included. Just what I needed for my Archive drives.

I know there are a lot of negative reviews and was thinking some of those could be discounted, well, not this time. So, the other negative reviews, believe them. Pros: - Looks decent in the package, on the desk, it looks like a gray mailbox. - I'll try to say a second nice thing, but can't think of any. Cons: - The enclosure amplifies the noise of a magnetic disk. I decided to use all solid state disks. - If you are looking for a single enclosure for multiple disks, it is that. Expect a single operation to be slow, and a second concurrent operation will cripple it. - If you have a Mac, this product is an afterthought. It is constantly dropping connections and you can't rely on it for Time Machine backups or really any continual file sharing activity on another networked Mac. This is not an Apple problem, this is a cheap enclosure problem. - If you want a true USB-C device, you need a USB-C to USB-C cable. So expect to spend more on a cable to connect this. Seriously, these people are trying to cripple their own products. - It's cheap plastic and aluminum. Will it last? I suppose if you don't drop it. - If you think it will run better on Windows, it runs like trash on Windows too. Happily I haven't lost data on it yet. But after a few hours of using it, I am very done with this product. It's going back. Save money and use multiple enclosures that are docked. It will actually work for you.

Rock solid addition to my storage situation. Easy to install drives, has a small footprint, and just works. USB-C connection goes straight into my Mac but could just as easily be into a hub. I have already bought two and often recommend this to friends as a cheap, reliable solution for drives you have lying around or wish to consolidate.

It works most of the time. Can't complain too much for the price. There are better units out there. Pros: Drive trays are nice and fit well. Drive click into place. All drives connect, nothing disconnects during transfers. Speeds are good. Cons: Sometimes, it shuts down on startup if full of disks. Seems like the power adapter doesn't provide enough power for all the drives powering on at once. Add 3 or 4 drives, let them power on, then add the last one. Door is pretty flimsy. Unit sometimes makes this extremely high pitched screech.

It will work flawlessly for about a week or two, then start struggling two weeks after that. After about a month, it starts making this horrible buzzing and clunking sound and you're lucky if you can access any data on any drive in a reasonable time frame. I've purchased 5 of these now, and every one of them has died the exact same way. Buzzing, clunking, then dead. One of these even killed a HDD of mine. Completely corrupted it. Avoid this brand. The cheap controllers they use on there can barely handle the load they claim it can, and has potential to mess up your drives! How fortunate for Amazon that every time one of these dies, it's a week or two outside of their return policy. Bah. Spend more money on a different brand. These aren't it. The money I've wasted on these I could have bought two of the Sabrents I had my eye on and been set. I should have known better though, so if I'm mad at anyone for the waste of money, it's me. Don't make the same mistake I did.
