Review: My second one - superb. - It was time for me to upgrade as I'd filled by previous one of these. They work so well I just bought another five years later. Highly, highly recommended.
Review: Happy - I bought this to replace a 15 year old TS-469L NAS that was having some transfer speed issues which I couldn't figure out. I realised I only ever connected to it from one computer so it made more sense to have it as a DAS for that computer so that I didn't have to mess around with endless Samba nonsense. Got it up and running quickly. Transferring from the computer's NVMe SSD to a WD60EFRX holds a constant 200MB/s on large file copies. Far far better than the TS-469L, which transferred at about 100MB/s internally, and seems more reliable. My only complaint is the locking mechanism absolutely sucks. It doesn't line up very well and has a tendency to spin round and round if you don't get it at the right angle. It's also only held in place with a push-fit circlip which is prone to popping off. Not too big of a deal for me as I don't use them. Note also that early versions of the TR-004 had a different JMS chipset to this one so older reviews may not reflect the current product.

### ⭐⭐⭐⭐ Cheap way of building a hardware RAID
*by M***T on 6 November 2022*

This is sold as an expansion caddy for a QNAP NAS – but I'm using it as directly attached storage for my home server. It functions perfectly well as an external caddy, and provides a little more functionality than a standard 4-bay external caddy, at a price that's competitive with other reputable brands. The Interface is USB-C, so it's pretty straightforward to connect to a PC or Mac. There are dip-switches on the back that allows the user to select between RAID 0, RAID 1 and RAID 10 – or leave the caddy in JBOD mode, so your computer recognises individual disks inside. I was a little wary of this – assuming one false move with the dip-switches would wipe everything – but after moving the switches, you still have to press and hold a button before anything useful/calamitous can happen. The buttons and switches are nice and sturdy, so there's no danger of doing anything accidentally. There's a big 120mm fan on this, which means it turns a little slower and runs a little quieter than on units with an 80mm equivalent. It's doing a good job of keeping everything cool. Running with minimal load, the 4x12TB WD CMR drives I have inside are running at 35°C for slots one and four, and 37°C for two and three. Setup as RAID 0, when copying 32TB of data to the drive, temperatures peaked at 55°C (S.M.A.R.T status) is viewable through the QNAP external RAID Manager software that comes with the device. I've had not particular problems with that. It did have a crazy day of going off-line in 12-second bursts four or five times. Can't figure out what caused that, may have been nothing to do with the unit – but it's been up now for two months and, that day apart, has ran like a sewing machine. Speed-wise, it doesn't seem to be particularly quicker than using a software RAID system like SoftRAID. My files copied at around 7GB per minute, which is what I'd expect from a JBOD caddy – but the Mac Mini to which this is attached seems much more spritely with this Hardware RAID attached than it did running a software RAID. So, overall, I'm very happy with the purchase.
