So i had a agility 2 ssd 60GB in my desktop and it got a 7.7 WEI in win 7. The bigger ssd give more performance, i just put a agilty 2 120gb and i am getting 7.2 WEI in win 7. I could not find an achi option in the bios. I am not sure if my machine is SSD optimized.
Regardless is there a setting i should change for ssd in win 7, i remember i changed something on my desktop ssd but it was a while ago i think it was the storage controller or something and that helped?
No the benchmarks are fine,defragmenting should not be done
You are asking about the intel storage drivers, usualy they are installed , I sometimes leave them out
Before you look for them ,run a benchmark with the recomended programs
Not horrible ,beats any normal hard drive ,but low
Read should be around 175 or so
Must be the Sata 1 interface is slowing throughput
I have not tried any new type faster ssd's in my cf-30's or cf-19 so I don't have the speed that you have so I don't know the limit ,but I bet the interface is the slowdown
Your running AHCI. If you weren't you'd get < 30MB/s 4KB Q=32 performance.
The problem you are seeing is the SF1200 SSD firmware pulls back the performance if you write a lot of non-compressible data, like do repeated CrystalDiskMark tests. Only way to fix to get back the full performance it is to secure-erase the SSD using say hdparm, which involves booting Linux, then hotplugging your SSD so it's not locked.
The OP's laptop has a sata-1 interface
I think thats the limit here
It's certainly a contributor. Though it will cap performance to < 140MB/s as is being seen. What I'm seeing is the sequential writes are 80MB/s. They should be faster than that.
I saw writes on my SF1200-based Renice X3 also get pulled back after doing a lot of benchmarking with non-compressible data. See examples, both on SATA-II below. A 120GB unit has *faster* write performance than the 60GB unit I'm using.

BOTTOM: after firmware has pulled back performance due to lots of non-compressible data benchmarking
