T480 - slow NvME C: drive

2020-04-30, 15:16 PM

Hello,

I have got 2x T480 with 256GB NvME SSD /Intel SSDPEKKF256GB8L) and I have noticed very strange behavior when copying files. Drives on both these systems go absolutely slow when copying files on C: drive, or when copying files from D: drive (separate NvME drive in WWAN slot). 

 

Speeds oscillates between 90-300MB/S in few seconds into copying simple *.avi files

Here is screenshot from CrystalDiskMark. I’m note if it’s ok or not, those number are not saying much to me.

This behavior persists on both machines. One is equipped with secondary NVME drive, which has pretty similar behavior, maybe with little less oscillating performance. 

 

Is it normal behavior? On the other hand, systems are pretty snappy (as can be expected from quadcore i5 + NvME). Am I missing something?

 

Thank you for all your answers!

Slow in the CrystalDiskMark results. Also in file transfers, but this depends on many things. Check that the SSD firmware is up-to-date.

Both systems are up to date based on what Lenovo Vantage says.
