This an interesting thought. I am looking to go even 1 step further and install the whole OS on a RAMdisk. One of my systems I am going to upgrade to 16GB of RAM and then I can fit my Windows 8 running in VMware which is a 12GB folder. That ought to be interesting too.

Gary, don't forget to report back on the experiment.

Will do when I read up some more about it. I've wrecked a few installs with my science experiments.

Wow, here's the initial result. The AS SSD only took about 7 seconds to run. Read access increased from .098 but Write dropped from .392.
Default settings other that setting the cache size to 3096MB

Here is my 512K Samsung 840 Pro after running a couple of weeks. Its scores are higher in all tests now except for Seq write which is 9.5% or 41.22 MB/s lower.

It says iaStorA-OK instead of msahci-OK. I'll check my AHCI setting in BIOS. Is this an Intel driver by chance?

EDIT: Is is still set in AHCI in BIOS.

iaStorA is an Intel driver and the correct one for an Intel CPU and is much petter performing than using msahci.

Thank you very much for the explanation. I feel good!!

I have an i5-2450M CPU. I installed an Intel driver that was recommended last week. I didn't realize that it was presented in the benchmark.

samsung has poor recovery from mass writes, if this is your primary drive and all your work load is on it, this is what happens not just to samsung but to all SSDs.

on the other hand heres 8k stripe SLC S301 Raid 0 in near optimal performance. see how the 512k went over 1200 MB/S LOL CDM went trippy cause of the small stripe size. 4k read went booming, could have gone to 60 if tested with 50 MB CDM file size instead of 100MB.

sequential and high QD drops though cause only 8k stripe size, if I default it back to 64/128k or even 256k it'll be over 1100 in both sequential read/write but 4k will drop down to ~45 MB/s

It is the low access time and the 4K numbers which are most important for running an OS on a SSD. 4K being the minimum page size written to.
