OCZ vertex 3 Issue?

[gavenr]

I am running BlackMagic Speed Test on my drive and im only getting around 130MB write speed .. but 400MB read speed. Didn't know if this was normal or should i do some tweaks to bios or os to get my write speed higher.

MB-GIGABYTE GA-990XA-UD3
Memory 8Gb GSKILL
AMD 1090t processor
OCZ vertex 3 SSD

run it again and see if it's going up t 500MB/s or close.. Dont run any program instead of the testing program and test it... Plug your SSD onto a 6GB/s port...

I'm positive its in a 6gb port. Also tried out only that program while testing it.. I also update my MOBO and SSD to current Bios and firmware.

Sandforce drives do not play well with the kind of data BM uses to test.

Still a lot faster than a normal HDD.

Manuf "advertized" speed is under ideal conditions, normally:
1) using program such as HDTack which usies data that is highly compressable. This is not real life. Real life OS + Programs lean more toward the non compressable. The Vertex loves compressable data.
2) Generally the "test Bed" is an Intel setup using the Intel ahci driver (iaSTor) which is slightly better than the default windows maahci driver. Not sure how the amd driver stacks up. This is probably valid as 80% of PCs use the Intel chipset.
3) Manuf tout Sequencial performance. This is the least important matrix for a OS + Program drive, it is the random 4 k speeds that are of the most importance.

Anyway, download as ssd and run it. Don't need to run the benchmark. Look at the uper left and verify the correct driver is installed and that the partition is properly aligned.

people keep talking about the partion aligned could you throw me a link and i can read up on it.... I do IT work for a living i just dont keep up with the SSD that much...
