Recently installed an 256 GB 840pro to replace a dead Kingston V100.
Clean install of Windows 7 home premium.
CPU: i7: 3820 @4GHz
MB: Asus P9X79 Pro
Memory : 16GB @ 1600 CAS 9
GFX : 480 GTX
The SSD is about half full, AHCI enabled in bios. But the speed test results are a lot lower than I was expecting, Random read : 52000 IOPS, Seq Write 184, Random Write : 28303
The writes are especially low (I did turn of AV before testing). It is plugged into 6Gb SATA connection. Trim enabled. Samsung magician set to performance. Can this just be down to the disk being 1/2 full? The write performance I get is not significantly higher than the Kingston drive which is 4 years old nearly.
Every other thread I've searched for its usually AHCI not enabled or plugged into a SATA 2 connector.
