If I remember right was about £120.
However I wonder if I have anything outside of the very basic consumer retail warranty, as although these originally had a lengthy Intel warranty, Intel has now fobbed of the whole product line to another company who now have it listed as a EOL product with no way to get firmware, to register it etc.
This was very likely the reason for the heavy discount.
The drive is definitely considerably slower than my consumer drives in certain tasks, noticeably in single threaded i/o. As an example my 860 EVO sata SSD beats it in single threaded 4k, although it will beat that on sequential.
At the time I got this NVME prices hadnt yet crashed so ultimately was still good value, I am using it for my heaviest write type workloads of which I will appreciate NAND performance.
It does of course have certain niceness, 30% factory over provision vs the consumer standard of under 5%, power loss caps which allows the drive to ignore all fsync at the drive level (so will be fast in certain fsync workloads), the chunky heatsink it runs really cool, so because of the factory over provisioning I wouldnt care about filling up this drive, I manually over provision my ssd's normally at 10%.
