Recently I've noticed considerable slowdowns of my Surface Laptop 1. After doing a CrystalDiskMark test, I notice that the write speeds are significantly lower than the read speeds.
SMART diagnostics come back 'OK'.
The drive inside is a Toshiba THNSN0256GTYA.
Does this indicate that the drive is about to fail, or could there be another cause of this issue?
Are there any other diagnostic tools I could use?
Sadly, in this laptop the drive is not user replacable, meaning a drive failure would be the end of the line for this laptop :(.
Any help is greatly appreciated.
