TB4 speed. Excellent cooling. Use RAID-0 for max speed. Daisy chaining works.
I am using a pair of these SSD enclosures to provide 4TB (main data storage) and 8TB (TimeMachine backups). I have these guys configured as RAID-0 storage for speed. Speed is > 2GB/sec and < 3GB/sec for large sequential file copying. I wanted to keep costs down, so instead of getting TB5 enclosures and TB5 rated SSD chips, I got the less expensive TB4 versions. Plenty fast enough for my purposes. When push comes to shove, TB4 is just as good as TB5 for random access I/O - which is what 90% of my workload consists of. Make sure to turn on the fans (there is a button). When I ran my first TimeMachine backup, the 8TB enclosure got hit. The fan cooled it off VERY nicely. These enclosures can be daisy chained. I have the 8TB connected after the 4TB. Very nice. Dead quiet.Have been using these guys for about 2 months with no issues. Value for $$$ is excellent. I recommend for anyone serious about using SSD for their main data storage and first level backups. I have used these guys on a 27” iMac and am currently using them on a Mac Studio.

As far as I can tell all it does is light up the LEDs when plugged in.
I have 6 m.2 ssds I want to pull data off of, then use 2 as extra space for work. I inserted two of my m.2 drives to start pulling data off of them, and...This doesn't do anything when plugged in, I used 4 different computers, two macs, one windows, and a linux computer. I initially plugged it into my mac pro, no response, no devices detected, nothing.Red power light came on with the included power supply, when plugged into the mac pro, the two blue ssd lights come on, but nothing was seen by the mac pro.I then plugged it into my windows laptop. I unplugged the power, and put the power back in. Red light on, blue lights on, no reaction from windows. I opened up the device manager, unplugged, plugged it back in. Blue lights come on, but no reaction from the device manager.Repeated this with another windows computer, and my ubuntu laptop. No devices I plugged it into gave any indication that it was connecting, as if the cable just existed to light up the blue leds.I plugged a device into the secondary plug, and it charged it. I plugged a monitor in, nothing as well.Basically, as far as I can tell, the device just lights up the LEDs and acts as a power pass through, and does nothing else.I tried each m.2 drive separately after trying the first two, the first two were 970 evo's, the other for were 990 pro's. They were all working immediately before I pulled them from the computer 20 minutes before trying them in this enclosure. None of the drives worked, the device was never detected by any of my computers, and I returned it because it's expensive junk as far as I'm concerned.

Amazing enclosure — simply the best
This is, quite simply, one of the best investments I've ever made. And I mean that. I'd been looking for AGES for a dual NVMe SSD stick enclosure that is small, utilizes Thunderbolt connectivity, and — most importantly — runs COOL. Well, this one checks EVERY box. This enclosure is incredibly simple to set up… and it INCLUDES thermal paste strips which you can place on top of your SSD sticks! It has a small fan (you can optionally turn "on" or "off") which is INCREDIBLY quiet (you can barely hear it a couple feet away) but powerful! I've run the most demanding tasks on the SSD NVMe sticks which I installed inside… and the entire time, the enclosure remains cool. And I mean quite literally COOL to the touch. I will be recommending this to all my friends and fellow feature film editors. Bravo, guys.

Not reliable as a RAID 1 device. On failure, both drives end up corrupted.
I installed dual 4TB Samsung 990 Pro PCIe 4.0 NVMe M.2 SSDs with the hope of using this device in a RAID 1 configuration to provide a redundant backup of my projects while I worked on them. But, unfortunately, any power interruption to the device corrupts both NVMe drives. For example, if your wife unplugs your wall adapter so she can move it to another outlet. Or, for example your dog bumps the cable. Boom. All your data on both drives is gone. I am so disappointed. I reformatted both and tried again, only to have it happen again. In the two days I have had the drive, I have lost both volumes 3 times. I'm lucky I was just testing and still had other backups. I'm using a Thunderbolt 4 port and do enjoy the speed. But I bought this for the redundancy, and it just doesn't do that.

Works Great! Some caveats, though.
Used this for months until I replaced it with Thunderbolt 5 enclosures. Very reliable! Since these have their own dedicated power source, they work better in my experience than enclosures powered by the computer's USB bus. Fan has an annoying pitch so I bought an external fan (https://amzn.to/4c9qysr) to blow on it . I bought 2 of these enclosures and turned the four SSDs into a RAID 0 array. Given that RAID arrays test drives/enclosures harder than normal use, I can safely recommend these.Heads up, the included power brick is large and the cable (I feel) is not long enough for power users. I have an adjustable height desk and the included cable wasn't cutting it. So I bought 2x of these https://amzn.to/428vwkoI found the brick wasn't reliably staying securely plugged into my uninterruptible power supply, so I used these https://amzn.to/4j8oDq3 and it felt much more secure.
