I have a Kingston mSATA SSD (Kingston SSDNow mS100 64GB mSATA Internal Solid State Drive SMS100S2/64G) I bought about 6 months ago. When I tested it with AS SSD Benchmark right after the first installation, the speed wear about 210 MS/s read and 120 MS/s write. Kingstons states 255 MB/s read and 170 MB/s writes so it checked out.
Over the last few days I started to feel the SSD is getting slow, so tested it again. I was very surprised I got 50 MB/s read and 13 MB/s write speed. It is a massive speed degradation, especially the read part.
Is this normal? I am suing Windows 8, the SSD and OS both support trim. I have about 15% free disk space.
Is your Windows 8 installation optimized for SSD? If not, you might be writing to the SSD way too much and might end lowering the SSD life. – Peter – 2013-02-07T11:59:04.043
@Peter I used SSD Tweaker from the start, so no indexing etc.. – Igor Kulman – 2013-02-07T12:00:39.770
It would be a pain but if you could clone the drive, do a secure erase and then write back the clone you could test if the degradation was due to writes over time. – Brad Patton – 2013-02-07T15:49:19.263
