Sandisk 120GB ssd poor performance

Report of <RAZOR-992964BBD>

I recently purchased a 120GB sandisk SSD from newegg, but am getting poor peroformance.

On the video advertising the product on the website, http://www.youtube.com/watch?feature=player_detailpage&v=YusmbpoDXEo#t=93s

They seem to be getting 4K QD1 reads of around 4500IOPS and writes of around 18000 IOPS
And for 4K QD32, they were getting around 28000 IOPS for both reads and writes.

In my case, I seem to only get around 4000-4500IOPS for all reads and writes under 4K QD1 as well as QD32.

overall, my IOPS are much lower than they should be

I have the drive running in AHCI mode (and have these poor results in both windows XP and windows 7)

“(everest does not detect my RAM properly)”

Yet it detected your 6 Audio Adapters correctly!!  Really?

hmm it didn’t detect all audio devices either.  should be 2 USB additional sound cards. 

Since USB microphones don’t offer proper software for noice reduction and eq, I have to use a roundabout way to run my mic and a few other audio sources through a software eq, software multiband compressor, then through noise reduction, as well as a few other filters set to reduce the sound of the keyboard as I type.

As for the SSD, it seems that the IOPS if far below normal. Would be good to know if anyone else is having this issue, with IOPS especially around 4K reads and wrts being well below advertised and well below some benchmarks.

In Device Manager is there an entry for the SSD under Disk Drives?  And if so are it’s Policies set for Quick Removal or Better Performance?

it is set for best performance and write caching

it is faster than a standard 7200RPM drive in terms of read speeds (whie speeds are a bit lower)

the main issue is that it is around 10,000 - 15,000 IOPS below normal for the drive performance when it comes to 4K.

not sure if I have an outdated firmware or a bad revision of the drive, but it is annnoying knowing that the drive is not running as fast as it could be

Felt it may also be good to note that my partition is alligned properly.

I suspect USB drive’s ratings are similar to MPG ratings of cars.  Some lab determines the ratings based on some ideal conditions which helps compare one device/car with another but is unlikely to be met by average users in average situations.

Does your mainboard support USB 3.0 standards?  Does your OS?  Do your drivers? etc
