CS900

I have a pure SSD server. your drive choice is terrible for a use case like a storage/remote server. the CS900 has no DRAM, so there is no write cache. the initial speed is because the PC on the receiving end is using its system ram as a cache, and once that fills up, you are back to the actual writ

The pny CS900 has no problem yet it is slow but in simple storage it cannot be used in native OS

So, the PNY CS900 is a very low end laptop Sata SSD and not suitable for anything other then a low end workstation or a low end laptop. I would not use them for anything like ZFS or hosting VM disks. they are DRAM-Less and rely on the controller direct IO access to NAND no PLP, so they do not cache

If the laptop has already 2.5" HDD in it, then you should be able to swap it for as sata 2.5" SSD like you found. Just be aware you need some USB to SATA adapter, for the data transfer / OS clone from HDD to SSD, if you don't have any other means for that. Ps. Do mind that CS900 like to fail, it's c

I am referring to the large amounts of complaints of overheating and failures in reviews. Also complaints that once the cache is saturated it hits 250mb/s speeds for longer loads. Apparently they also did bait and switch QLC in while advertising TLC. it has 8% 1 star reviews on amazon vs the micron/

You might find this helpful. The PNY CS900 appears to be of cheap overall quality hence poor performance is to be expected. If your mainboard supports, I would invest in a proper Gen4 NVMe instead of relying on a SATA SSD.

Oh, glad it worked for you! I'm having the same problem but using the PNY CS900 lol. I don't really know what else I can try then. Maybe another version of OPL? Any suggestions? Thanks!

Your stress tests mean nothing if the issue is intermittent and not load-dependent. Random stutter + freeze, no thermal throttle, normal usage readings? That screams storage I/O hiccups or power delivery instability. That PNY CS900 SSD is a known weak link. DRAM-less, budget-tier, and it WILL choke
