[SOLVED] Slow performance on M.2 SSD

[prahadan]

I upgraded my Dell Optiplex 5050 by replacing the standard HDD boot drive with a WD Green 240GB PCIe SSD. For the majority of tasks (booting, everyday activity) it is lightning fast, but I've noticed that when working with larger files for video editing or transferring/unzipping large files, performance seems to really slow down. The SSD frequently maxes out at 100% in the task mgr causing a bottleneck and the system grinds to a halt. What's happening?

These are the results of the AS SSD Benchmark: https://drive.google.com/file/d/1J9JmNGKbR2_yYzDD9MgtRNXcS2zxfHLL/view?usp=sharing

Any thoughts on what the issue might be? Could it be related to the BIOS settings, driver or controller?

Thanks,
Dan

The WD Green is one of the slower performers from the mainstream manufacturers.

Large file activity fill up the cache, and it slows down to near or below HDD speed.

There is no setting you can change for this.

Anything with the word "Green" in it from WD is not something you want for performance.

if dealing with large files you want more than 240GB, generally speaking the bigger the drive, the more cache/speed it has.

I would suggest replacing it with a larger 1TB NVME drive.

Be sure this next SSD is an NVME!!!!!!You will get more like 3000/mbs instead of 500.

Welcome to the SSD tier list. SSD or Solid State Drive is a storage device containing non-volatile flash memory, used in place of hard drive because of its much greater speed. Unlike a hard drive, a solid state drive doesnt have any moving parts. It has two main components - A flash controller an...

If it not too late I would return the Green 240gb.

Super helpful, thanks for your replies.

The WD Green has been a big upgrade on the previous HDD boot drive in general, so I'm happy enough for now. As I did the upgrade myself, I just wanted to make sure that I hadn't made an error in the setup that was causing the SSD to slow down when working with larger files, but it sounds like the benchmark stats are to be expected for this setup.
