Why does HDTune report better performing drives 2 months after installing them?
- by Rolnik
OK, so this is really weird. I ran HDTune on a newly set-up home-built computer and got the following readings from my drives in mid-November.
SSD 154 MB/s
RAID1 87
RAID0 198 (software installs)
RAID0 98 Swap drive
Today, in January, I run HDTune (same version) and get these results, in MB/s:
SSD 186
RAID1 98
RAID0 241
RAID0 98 (Swap drive)
Here are more details that HDTune reports on the SSD drive:
HD Tune: OCZ-VERTEX Benchmark
Blockquote
Transfer Rate Minimum : 135.4 MB/sec
Transfer Rate Maximum : 219.4 MB/sec
Transfer Rate Average : 185.7 MB/sec
Access Time : 0.1 ms
Burst Rate : 187.3 MB/sec
CPU Usage : -1.0%
To get to my question: Why are my hard drives improving in performance? Most of my logical drives are in some form of RAID, except for the SSD. Will this performance ever deteriorate? Note, none of my drives are a hybrid drive that uses some form of SSD to enhance the write/reads on actual platters.
