I have an OCZ Agility 3 60GB SSD. I use it for booting windows and BF3. I ran a Read/Write test today with CrystalDiskMark and had some strange results. The SSD is running at AHCI on a SATA 3 port. I have a AMD Phenom 1100T X6 running at 3.8GHz. When running the test I realized I only got around 200 MB/s read and only 60 MB/s write compared to 100 MB/s with the HDD. Below are screen caps.
I'm confused as to what is causing the write speed to be this slow with the SSD. It is running the latest 2.15 firmware.
its only faster if what you are writing is written sequentially in which on a drive that size is very unlikely. And that would need to be a pretty big file so that is not really an issue. the other three write numbers are a bit more important unless you are using the SSD for Video storage and large archives.
CrystalDiskMark uses incompressible data to test Read/Write speeds.
AS-SSD also uses incompressible data to test Read/Write speeds.
Advertised AS-SSD speeds for your drive are "up to" 180 MB/s Read and 65 MB/s Write.
If you are looking for the 525 MB/s Read and 475 MB/s Write speeds you need to benchmark with ATTO.
Also ensure that AHCI is enabled. AHCI was not enabled on my OCZ Vertex 3 120GB and my read speeds were about 310 and my write speeds were around 90. I enabled AHCI and my read speeds went to 470 and my write speeds to around 140 (using CrystalDiskMark).
