I have a computer that I put a 256 GB 850 EVO SSD on about a year ago. I have had intermittent slowdowns accessing some files.
AIDA64 reports the drive is slow at the beginning and OK in the middle and end. Random and buffered looks a little slow also. Another benchmark program would barely run one day and it was fine a week later. I am running Win7 64 and have used samsung magician to optimize (trim?) but do not run it normally.
I have another computer with a 500 GB 850 EVO and no problems. Both computers have the SSD as the boot drive and storage hard drives. I have included a snapshot.
I do not understand trimming the drives, am I doing something wrong? Smart reports lifetime writes is 1TB and 99% remaining drive lifetime.
