Windows 10 1511 (Nov update) SSD issues (100% usage,low speed,freezes)
Hello,
I'm running out of ideas on this one.
I've been facing multiple issues post Nov update, I already managed to fix corrupted Nvidia drivers and few others.
My SSD which is my System drive started behaving very strangely.
Hardware:
Lenovo Y580
SSD: Adata SX300 64 GB
Issues noticed:
- file transfer (within SSD) speed drops from 300 mb/s to below 1 mb/s - Imgur: The most awesome images on the Internet
- 100% disk usage & very high latency while performing minor or major i/o operations. Screenshot taken at the same time as above - Imgur: The most awesome images on the Internet
There's no single process seem to be causing this - Imgur: The most awesome images on the Internet
This causes System to freeze for/every few minutes and overall bad performance.
What I've tried so far:
- safe mode (same symptoms)
- disabling Superfetch/Prefetch/Readyboot/BITS/Search
- disabling Windows Defender
- running HD Tune & others (no bad sectors, disk condition is ok, SMART shows ok)
- updating SSD firmware & driver
- updating windows AHCI driver
- disabling MSI mode (https://support.microsoft.com/en-us/kb/3083595)
- disabling file indexing & defrag
- removing all recent Windows updates (Nov update cannot be rolled back)
- running sfc & dism (found only minor errors related to GPU driver), chdsk is ok
Did anyone notice antyhing similar?
Any ideas? Do you think it's hardware or software related?
Sorry for poor grammar. I will apreciate your help.
