Poor 4KB Random Read Performance. Normal?

[idata]

Hello Community,

I just recently purchased a X25-M G2 160GB for my laptop. I installed it, updated the firmware, did a clean install of Windows 7 64-bit Home Premium and installed Intel SSD Toolbox and Rapid Storage Technologies as well. However, as I benchmarked the SSD, I noticed a problem with the 4KB Random Read Performance. As you can see from below, the 4KB Random Read is only 10 MB/s which is even lower than the 4KB Random Write of 28 MB/s. I was wondering what's wrong? I have tried reinstalling Windows, running SSD Toolbox, and checking for disk alignment. However, nothing seemed to improve the 4KB Random Read performance.

Your feedback is much appreciated,

John

Here's my system info:

You need to go into the motherboard BIOS and disable C1E, all C-states and Speedstep (EIST). Unfortunately, for p55 and h55 and h57 motherboards, the energy saving features need to be disabled because they make intel SSDs slow down quite a bit. Maybe Intel will fix this one day!

Some people said turning off VT also improved speed a bit but I didn't see any benefit in benchmarks.

Nice Call.

You can also go to the SSD Review below and see the benchmarks for that SSD.
