Asus M4A89GTD PRO/USB3 MB
AMD Phenom II x4 945 3Ghz.
Samsung 840 EVO 250 GB SSD - boot and system drive
4x Samsung 500 GB RAID 10 on separate volume
I recently replaced a Kingston 128 GB SSD with a Samsung 840 EVO 250 GB drive because I was getting disk errors on the Kingston. The new Samsung drive just doesn't seem as quick, which surprised me because I was replacing technology that was several years old with one that is more current. I didn't replace my Win 7 image, I did a full re-install. The overall performance seems to be a bit sluggish. I downloaded a disk performance utility called CrystalDiskMark 3.0.3 which was recommended by some site which I don't remember.
-----------
The Tom's Hardware performance tests state the following for CrystalDiskMark Random Read/Write, 4 KB (QD=32):
Read: 394 MB/s
Write: 294.10 MB/s
On my system, I get the following metrics:
Read: 32.23 MB/s
Write: 67.51 MB/s
-----------
The Tom's Hardware performance tests indicate the following for CrystalDiskMark Sequential Read/Write [MB/s] ver 3.0 x64 (Test : 4000 MB, Repetition: 5x):
Read: 540.10
Write: 418.60
On my system, I get the following metrics:
Read: 302.2 MB/s
Write: 292.4 MB/s
-----------
The variance on both of these tests suggest its more than just a lab/real variance. Any ideas? Thx.
