Looks slow for an NVMe?



Quoted speeds mean nothing, its just willy waving from the manufacturers. In reality its probably 90% the performance of a Samsung 970 EVO at less than 50% of the price

Excellent price with 5 year warranty. Thank you @Brutes
Not bad - prices seem to be coming down!

Voted hot, I have 2tb version of this.
Decent price for a respectable 512Gb NVMe
1tb model of this drive available from scan for £98.87 if anybody needs higher capacity, that's before any delivery cost.

This is the same article I found yesterday. Good info, helped me understand the differences a lot better.
I've seen reviews of this. It's a QLC SSD and it's really ~SLOW~ for copying a large amount of files. You're much better off with a normal TLC SATA SSD.

Every review i've read puts this in the middle of the pack in it's capacity class, in the real world, you wouldn't notice in most workloads, even when the up-to 76GB of SLC cache is full, you still get decent r/w performance, i'd be interested to read a review that shows otherwise and what they had to do in order to exhibit the issue.

Famous video. (It's the same with the Crucial p1 QLC SSD. Once the SLC cache runs out it slows down to a mere 150Mb/s from 1600Mb/s.) There's a reason why the intel 660p is so cheap, right? Once the SLC cache runs out it has to write in QLC mode so it's much slower and then you'lll regret it.

If you watch the video, it’s conclusion is effectively that it’s while technically it’s inferior to SLC/MLC/TLC, the overwhelming majority of users and usage scenarios will never experience any slow down. Would I put one in a server I write 15TB/day to? No, but it’d be fine for general workstation/desktop usage where you don’t routinely write several TB’s a day - as this example is a 512GB drive, that seems an unlikely usage scenario. I went shopping after this deal got posted and picked up a 2TB 660p for £149, you can’t argue with the VFM of that in an appropriate usage scenario.
