MAIWO External SAS/SATA Hard Drive Enclosure for 2.5/3.5 inch SSD/HDD, SAS to USB3.1 Converter, 22TB Storage Expansion, Plug and Play

Have the SAS version and it has lit up every SAS or SATA drive I have thrown at it so far. It worked with a 22TB drive which my other case failed to do. Zorin OS saw it and allowed me to format and use it very fast. Pushed 150GB of data to it out of the chute from my NAS out of the chute with no issues and a sustained transfer rate of ~100MB/sec (GigE network limited.) The SMART function on the drive I installed worked just fine. Now the shell is aluminum but the sled/board carrier is simple plastic. So heat with a drive like the Western Digital Ultrastar DC 570 22TB WUH722222ALE6L4 (admittedly an enterprise NAS drive expecting of active cooling) will not result in a happy drive by any means. IE: the drive will for sure cook. Mine, without the shell in my open room at 74F, was idling at 117F. This means that though it will in fact present most any drive to your USB port. But just because one can do a thing doesn't necessarily mean one should. For the IT types, likely the target of this unit since it is a SATA/SAS device, you will wanna leave the shell off at the least. With those limits in mind I highly recommend the case just based on the function. with

A SAS enclosure that actually works properly. Supported my 2.5 inch ssd 3.84tb sas drive with no issue. The holes for the smaller drive actually line up unlike other brands.

Works and was the only game in town when I bought it, but it's very, very slow unfortunately. The issue is that the initio controller they used is limited to 80MB/s (yes, you read that correctly). The board miscommunicates the actual data transfer rate to the operating system; benchmarking under linux disks application reveals that the write speed is limited to roughly 80MB/s. It was the only option for a external SAS/USB enclosure when I bought it back in 2025 but it looks like there's different options available now. "The Initio INIC-1611 provides an advanced solution to connect SATA devices to USB or SATA Host with integrated CPU and embedded SRAM/ROM. To provide high performance and cost effective solution, the INIC-1611 integrates USB-PHY Mass Storage Class Bulk-Only USB function, SATA link/PHY core and microprocessor into a single ASIC. The INIC-1611 provides the data transfer rate of up to 60 MB/sec connecting to a 1.5G SATA interface. " It's not a huge deal for my use case because I'm using rsync and most of my data doesn't change between backups, but if you're moving tons of data around look elsewhere.

This is the first SAS to USB enclosure I've had that actually does what it advertises. Had problems at first with drive seating. Hard to push the drive into the connector on the enclosure. Transfer rates are similar to SATA. Up to ~120MB/s, but not what you'd normally get with SAS drives and a real controller. SAS are enterprise drives normally found in data centers with good cooling. Drives in this enclosure run HOT, but don't know about longevity. You wouldn't want this running 24/7 on your desk.

250 MB sequential read. (verified with both packaged cables as well as my own usb 3.0 cable) This is SLOW. This is at least 20x SLOWER than it should be, and barely faster than my old consumer grade 5400 RPM external HD. The enclosure is NOT built well. It looks nice, but the piece that contains the SSD slides around. You can't push the power button without sliding the SSD around, and this would definitely not be good to travel with.
