Lexar 8TB NM790 SSD PCIe Gen4 NVMe M.2 2280 Internal Solid State Drive, Up to 7000/6200 MB/s Read/Write, Compatible with PS5, for Gamers and Creators, Black (LNM790X008T-RNNNU)

Snagged one of these pre Black Friday for CAD$668. That's a decent price: earlier this fall I got the 4TB version for CAD$275. Both of those sticks are now in my UGreen NXP4800 NAS box, running Kubuntu 24.04. I've given them a solid workout now, with several TB of data in/out, and both Lexar NVMe sticks have performed very well. Fast, no sign of any slowdowns under load, and they run cool. The 8TB is in the 45-47C range, and the 4TB at 30-33C, very safe temperatures. Anything below 70C is fine, really, and these don't even get close.A great deal at the sale price, not so good at the "normal" $900+ numbers.

Works, always have important data backed up on spinning rust when possible though.

It suffers a similar problem to other lower value M.2 SSDs and the old Samsung 980 - it performs very well until the cache buffer fills up, then the data transfer rate throttles right down. I use this drive for video files (so large files that want contiguous blocks of memory. Initially, it starts off transferring at about 2200 Mbps (Using blackmagic speed test), but for a sustained 5 minute test, the speed throttles right down to more like 800Mbps, and this is very likely to the cache/buffer filling up. You are better off getting the WD Black SN850 or the newer generation.

I bought this drive to place in my Thunderbolt 5 dock and use as storage for all the samples I use in music production. Installation was easy and my Mac recognized the drive and formatted it to APFS with no problems. Blackmagic speed test results for Thunderbolt 4 connection are 2183.6 MB/s write and 3110.8 MB/s read. As long as you're not editing H.265 12K video in real-time, this drive is fast enough to use as an external work drive on an M4 Mac Mini for video editing.

Fast and easy to install. Only negative is it is very expensive.
