CENMATE Aluminum 2 Bay 10Gbps Hard Drive Enclosure with Cooling Fan for 2.5“/3.5" SATA HDD/SSD with USB A/C 3.2 Gen 2, Support Hot Swappable, Tool-Free HDD Enclosure, DAS(NO RAID/NAS)

I admittedly haven't had this DAS for long (at the time of writing this review), but I will keep this review in mind and edit it should any of the below change. I was running Ubuntu Server 24.04 with Frigate (Linux-based NVR software) at home, but as I added cameras over time, the old server was a little too weak. I moved the Ubuntu/Frigate install to a higher powered micro tower which solved the first set of problems, but of course I had no room for a 3.5" HDD for the video storage in the replacement system, which is where the Cenmate 2 bay unit comes into the picture. I have a single 6TB drive in it. It's USB'd right into my micro tower. Ubuntu mounts it via UUID on startup, and Frigate takes over recording footage to it without issue. So far, it's a very boring unit - which is exactly why I like it. I was concerned about throughput speeds, so for kicks I generated a bogus 10 GB file and transferred it from the onboard NVME SSD in the micro tower to the WD Purple within the Cenmate DAS. It sustained 170 MB/s transfer. According to random searches online, that WD Purple is expected to handle about 180-200 MB/s write speed, so seeing 170 MB/s sustained write made me pretty happy. I should note, I am not using the included USB cable. I read a few reviews that suggested the included USB cable is problematic for some folks, so I opted to use my own existing USB A/USB C cable from the get-go. Another concern I had was the behavior of the unit in the event that the power switch is left "on" but power is lost and then restored, as it's critical for my particular setup that the DAS simply always be on if power is available. I decided to test this right out of the gate, so once I unboxed the DAS, I put my HDD in it, flipped the power switch on, and then after that I plugged it into the wall outlet for the very first time. It lit up and I could feel the drive motor spinning up. I tested this in total 3-4 times, and each time it simply fired up the drive since the switch was set to "on" already. While this may seem like a "duh" thing, some different units I compared contained some reviews that suggested even if they had an explicit on/off toggle (like this Cenmate does), if power is lost, and then restored, some of these other units reportedly still required turning the switch off and then back on. This didn't seem to be the case with the Cenmate, which is great as this would have been an instant deal breaker where I would have returned it. In my setup, it's a requirement that if power is lost and then restored, that the DAS kick on automatically since the NVR micro tower is also simultaneously booting up which would be expecting the storage drive to be present to begin recording feeds. It was a relief to see that the Cenmate behaved as I hoped it would with auto-power-on after power is restored. I can't comment on using two drives in the unit as I haven't had a need to yet, but with a single drive it does the job well so far. It's simple, but I needed simple as well as predictability. Given I have an available bay open, it is tempting to pick up another matching HDD and doing some sort of Linux LVM group to span the two drives for more CCTV storage, but that's a project for another day. No issues with this relating to Linux. My Ubuntu Server install simply saw the drive when I ran "blkid", I added it as an automatic mount point, rebooted, and there it was - ready to be used. The jury is still out on long term reliability. For now, I rigged up a script on the Linux system using the Cenmate DAS along with my uptime monitor server which will check for the presence of the Cenmate/CCTV HDD every 5 minutes and email me if there's an issue. I'm hopeful this will reveal no surprises over time, but if it does, I'll update my review here. For now, it's serving my Linux/Frigate NVR micro tower just fine and ticks what few (but important) boxes I needed.

I’ve been using this hard drive bay with my home computer for a few months. It has worked flawlessly. The speed is sufficient for backing up to the Western Digital 8 TB drives I use. There is a constant low level of fan noise when located on my desktop. I expect the noise to not be noticeable once I move the bay to underneath the desk. I like the disk mounting trays as they are easy to use and don’t require tools. The trays are not very sturdy, but acceptable for home use. Connection to my Mac mini was simple without any issues.

Nice multi-disk enclosure, easy to install HDDs, and worked as advertised. I loaded 4 HDDs I had on-hand, two 4TB and two 2TB, and it read each one without any problem. But (and there's always a "but"), the fan makes a lot of noise. I read the reviews by others that mentioned the fan noise, but thought they might be exaggerating. They weren't. My wife said she could hear it from another room. I ended up returning it and purchasing an 8TB HDD.

This is a DAS (Direct Attached Storage) device which means you can plug it directly into a desktop or laptop and the computer will see each hard drive in this just like it would if you had installed it into the computer. Because this uses the fastest USB version (at the time I purchased anyway) the transfer rates are even faster than what my old computer was via internal SATA connections. Either way I'm using mine on a laptop with 4 drives for a Plex server and its working excellent and can load and play 4K files from the 7200 RPM drives I have it in which my other computer wasn't capable of doing and only worked correctly on SSD drives. The huge storage capability of this made it a no brainer for my plex server and because there are no screws required for the drives to be installed that was super easy. I was a bit concerned about the noise level that people had mentioned in other reviews. In my case I put this in my office where it stays on 24/7 and its no different than having my other computer running fan noise wise. So you can hear it running but its nothing I would call loud. If you prefer silence though it might be best to put it in a room you aren't in constantly or maybe in a further back area of the room not as close to you. But it is absolutely not loud, just a low fan noise and doesn't bother me at all and I sit about 5 feet away. Setting this up was about as easy as it could possibly be. I just connected it to power and to the laptop with USB-C, popped my drives (WITH DATA on them still) out of my old computer and put them into this enclosure with no tools required, slid the sleds back in one at a time and they started showing up on the computer within seconds. IF you buy a brand new drive do the same thing but then go to Disk Management and initialize the drive and assign drive letter/etc. and you'll be good to go in no time!

Device seems well built, but when I installed two SATA WD Gold 16TB drives, the device did not recognize either of them. The drives worked properly in other devices. This device simply kept flashing the blue light for each drive, and there was nothing in the instructions about what a flashing blue light meant. (Per the instructions, a properly functioning recognized drive should show a solid blue light.) I then installed two Seagate 8TB drives, and again, all I got was flashing blue lights. I then installed the 8TB drives into an older device, and they worked fine. I then installed the 16TB drives into the same older device and the drives did not power up. I installed the 16TB drives in two other devices, and they did not power up in any of the three other devices. This unit fried my two 16TB drives. I am not happy.

I think this is a great product. It seems very well constructed and includes everything you can think of. I am replacing my tower desktop that has multiple SATA hard drives, and purchased this device to attached similar drives (2TB and 8TB) via USB 3.2 instead of SATA. I was concerned about the speed of the device, but I did some benchmarking and the USB connected drives on the Canmate and MiniPC actually operated maybe 5 to 10% better than the similar SATA-mounted drives on the old desktop. The new MiniPC has a faster CPU, not sure how that affects disk benchmarking performance. So, being concerned about performance bottleneck on USB to the drives, is a non-issue. I also tested an SSD drive in the device, and all the scores were noticeably better than the HDD, except for the sequential writes actually dropped about 5%. I am using one drive for backups, so I think sequential right speeds are important, but the other is for scratch data where I think random read/writes are more likely. In otherwords, changing one drive to an SSD will most likely, but not always, offer me better performance. If I had to make one complaint, the fan can get a little loud. While initially setting it up, I had the fan facing me, and it was noticeably loud. Turning the device around to it's normal position helps, and being in an office environment helps drown it out. I suppose if I really wanted to I could upgrade the fan myself to a silent drive, but I don't want to void the warranty. Over all, I am pleased with the cost, construction, performance and operation of the device. It seems like a simple device, so I'm hoping that it will be lasting several years.

This works if you do not expect RAID or Storage Spaces. Both drives are displayed with the same ID, so they can't be addressed separately by mirroring software. It works fine as a drive array for two separate disks. It's quiet and we've had no issues with transfer speed or reliability.

Great backup storage, for those with extra drives setting around. I love the easily removable bays, and how easy it is to add the drives. For full size drives, there is side rails that pressure fit into the side screw holes of the drives, taking just seconds to attach. For 2.5 drives, the rail closest to the drive needs to be removed, which is easy to do, as it just snaps off the drive bay, and then you use the included screws to attach drive to bay.. which is quick and easy to do. The drive bays inset and engage smoothly. The power adapter and usb cable are included. And love that there is on/off switch on back of chassis. I added drives, went into the Manage Function in "This Computer" in Windows - initialized drives and added drive letters - and voila - drives present and available. Unit works great, and file transfer speeds are adequate. AS for FAN NOISE - I saw reviews that complained about this - HOWEVER - on my unit fan noise was negligible, with the fans in my desktop computer being louder. Maybe mine features an upgraded fan, so for me I am very satisfied. Would buy again (and I have ordered the Raid ready model), and would recommend this unit.

Goed

Ottimo prodotto in metallo che da immediatamente un'impressione di robustezza e che consente di riutilizzare 4 hard disk o SSD Sata. Il montaggio è molto semplice e non richiede, nel caso di HD da 3,5, viti o attrezzi che, comunque, sono forniti dal produttore. Una volta collegato gli hard disk vengono immediatamente riconosciuti da Windows 11 come dischi singoli, non e' quindi adatto ad un uso Raid. La ventola non è molto rumorosa ma piuttosto potente e funziona perfettamente, la connessione USB 3.2 rende i trasferimenti molto veloci. Utile anche la possibilità di spegnere l'intero HUB. Vista che la qualità costruttiva, il prezzo, rispetto ad altri prodotti similari, e' molto competitivo. Logistica Amazon eccellente come sempre. ,

Sharp corners on the HDD bays where you press the release mechanism, some of the bays do not go in smoothly and the HDD bays are made of plastic and feel flimsy. So build quality is less than desirable considering the price. But other than that everything works.

Excelente producto... se instala en nada y los discos son facil de montar... tampoco me molesta mucho el ruido

Die Festplatten ließen sich leicht einbauen. Die Inbetriebnahme war ein Klaks nur der Lüfter könnte bisschen leiser sein. Ansonsten gutes Produkt.
