MAIWODual Bay Raid Enclosure for 3.5" SATA HDD,2 Bay Hard Drive Enclosure with Cooling Fan,4 Raid Modes,USB3.0 HDD Bay for 44TB Capacity Expansion

This dual-bay enclosure is a fantastic value at under $60, perfect for building a budget-friendly NAS or media center. It's easy to set up for basic storage needs and reliably handles larger drives, unlike some cheaper enclosures. With RAID modes, fast USB 3.0 speeds, a sleek but unintrusive look, extra usb ports for daisy chaining, and a relatively quiet cooling fan, it offers solid performance and features for the price.If you're looking for an affordable and dependable way to expand storage or create a simple NAS, this enclosure is a great option. It's user-friendly and performs well, especially considering the price point.

Hard drives go in, i mean thats about all it needs to do, the raid settings could have been a bit better they got bumped and knocked it (donno if switches were the best idea) but otherwise runs great!Dont put a hdd in here if theres anything ALREADY on it you wanna keep cause you'll have to knife fight a koloa bear to keep it* (alzo setting up raid wipes the drive)8/10

This disk enclosure worked for six months and stopped. And what's crazy is I was using it for backups, so I used it maybe once a month in that period of time.Troubleshooting is pointless as the manual is in pure "chinglish" and has very little info anyway. I will not be buying any products from MAIWO again. I wish I could say the same about any products from China too.

Ordered this Raid controller system to use as a remote backup for a server I have. This Raid controller is very easy to setup and using a VPN and dedicated IP address I was able to create an offsite backup location to protect data. This raid controller is very quite and very easy to setup. It took maybe ten minutes to get everything configured and start backing up data. This controller is very compact as well and fits very nicely in my backup location. This raid controller is also very sturdy and can easily take a significant hit without sacrificing data.Overall, this is a really easy to use raid controller.

This is on par with other HDD enclosures in terms of its functionality and features. The form factor is a little less compact than others I've used. I don't actually use the built-in raid functions. I find with these kinds of enclosures it's better and more reliable to set it up so each drive is it's own external drive and if you want raid then use software raid in Windows or something like that. Overall it's a decent option and works well, but there's not a while lot setting this apart from others like it so pick your poison.

You can put two ssd cards in it but can only hold up to 44tb with both so make sure you you don't go over that or you'll miss it up I've been using it and haven't have any issues with it

Was working as a drive mirror, today both disks are functional but empty.

For a 3 star review, a drive bay enclosure should be able to hold the number of drives it advertises, connect at the speed it advertises, and do it without letting the drives become corrupted. 4 and five star reviews means the enclosure has surprise features that make it easier to live with.TL;WR: If you have an Intel/AMD based system, this might even be a 5 star dual bay drive enclosure. If you're on ARM, it's really a one or a two star enclosure. Both platforms it connects at the advertised USB 3.0 5Gbps bandwidth, and is UASP capable. RISC V? Thar be dragons! (a.k.a. I have no idea)Curious how this still managed to pull out a 3 star rating? Buckle up and read on...As stated above, on an intel(ish) based system, this enclosure rocked. It connected by uas on Fedora, and offered speeds that were only bottlenecked by the drives themselves. If you have an Arm based PC, it's rougher; a MacOS with an M2 chip, it was ridiculously slow. On a Linux based SBC (my intended application), this thing absolutely will corrupt the data on your drives if you don't take extra-measures.Quick aside on MacOS: I've got a M2 Macbook Air that I attempted to play with this enclosure on, just to see if worked on a "mainstream" OS. As stated, it was ridiculously slow, and I suspect it's because the USB bus was getting reset very (very, very) often, but that's just conjecture. My Mac wasn't the targeted system, so I spent no more time on this side quest.On my Fedora PC (my daily driver), running very vanilla (*ahem* "old") x86_64 hardware, this enclosure offered the best speed I've seen in an enclosure (bar my Crucial X8 external SSD). So my drives were partitioned, formatted, and had gibibyte after gibibyte written to them to make sure there were no problems. No hint of problems monitoring via dmesg. Surprise number 1, the enclosure allows SMART monitoring, something a majority of budget enclosures don't offer. On an intel system this makes it a 4 star enclosure. To boot, even torturing the drives, with the fan on high on the enclosure, the temperature never crept above 42C, which leads to surprise number two: this enclosure emits almost no noise even with the fan setting on high. 5 stars.The only chink in this things armor, on x86_64, is that this thing needs an overly complicated adapter to use a 2.5 in drive. Since it's 2024, and NVMEs rule the land, and 3.5 drive are targeted for big Homelab/Enterprise storage systems, easily taking 2.5 drives on a dual bay enclosure should be a no brainer feature to include, but seemed to get overlooked. (hint - look at the Orico 2.5 to 3.5 drive bay adapters)When I connected the system to my Rockchip based SBC, that's where everything good was undone. My first couple of boots weren't even successful because the filesystems couldn't be mounted. Checking logs, it was having issues mounting /var, and even after succeeding I'd see the following stanza repeated over and over:kernel: sd 0:0:0:1: [sdb] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=DRIVER_OK cmd_age=10skernel: sd 0:0:0:1: [sdb] tag#0 CDB: opcode=0x2a 2a 00 0c fc 5d a2 00 00 68 00kernel: I/O error, dev sdb, sector 217865634 op 0x1:(WRITE) flags 0x800 phys_seg 2 prio class 2kernel: EXT4-fs warning (device sdb5): ext4_end_bio:343: I/O error 10 writing to inode 14647308 starting block 108932817)kernel: buffer_io_error: 154 callbacks suppressedkernel: Buffer I/O error on device sdb5, logical block 58600154kernel: usb 4-1: reset SuperSpeed USB device number 2 using xhci-hcdThe root of the problem is the Sharkoon chipset (Duck, Duck, Go: "Sharkoon will it play" on askubuntu.com). The answer to the problem is to blacklist the chipset (ID: 0x152d:0x0561) from the uas kernel driver. Once using the standard usb-storage driver, everything is stable, albeit 20% slower (the price of giving up UASP), so that takes this from a 5 star device to a 4 star device.If you're going to advertise your device as MacOS and Linux compatible, you NEED to make sure that's the truth for all hardware platforms a common consumer might use (and ARM based SBCs *cough*raspberry pi*cough* are common enough to be considered mainstream). Down to 3 stars.
