Experience of QLC drives - Be aware

[sityeuropa]

I've started to swap out my Crucial P3 drives as the performance when you have filled them a little is very bad.
The more storage that is used on them thhe more this will diminish the write speeds. I don't know the exact numbers but when copying big files you will constantly hit bottlenecks.

After 250GB the transfer will drop to around 80MB sec

They are worse than a Crucial MX500 for copying large files.

I knew about the Cache but just just wasn't expecting the drops to be as low as 100 MB for single file transfers.
Probably did just assume with how old the MX500 SSD was and the jumps advertising GB/sec write speeds. Surely it wouldn't be as worse in that area than it.

Didn't know MX500 is TLC so I suppose it makes sense as they are still around £220 for 4tb.
