Write caching is disabled by default with the Intel RST driver.
Open the IAstor utility and enable write caching on the array. You need to disable the Windows caching first under disk drives in Device manager (check the 2nd box under policies) then open the IAstor utility. That will improve the 4K's. Overall your benchmarks look fine, save the 4K in AS-SSD.
Ok ill try that.
What exactly does that do ?
just leverages the system ram to greater extent.
How much of a gain is this supposed to yield? I run a single SSD in AHCI and I ran a CDM with it on vs a CDM with it off and there was no difference at all outside the normal tolerance of benchmarks on the same setup.just leverages the system ram to greater extent.
I ran this one next.
It appears to suck.
Something is funny with this new install I have and I can't figure out what it is.
My old SSD (120GB MAX IOPS) Felt way faster than this VERTEX3 Array. (120GB x2)
I did this once before it felt wayyyyy faster.
Wondering if I messed something up or a driver is wrong ???
Advice?
Mfusick,
Did you enable write caching in the IAstor utility?
Did the benchmark for 4k's go up? That is all that will really change. What kinds of numbers are you expecting from AS-SSD with 2 in RAID0? and what part of the benchmark do you think is slow?
4Ks match my 3yrs old single intel G2 drive. access time is awful.
-128 kb stripe size ? -my old 120 g2 R0 intel suggested 16 kb
"2600k CPU is on "auto" and default everything"
-does your 2600k idle @ x16?
if so there's a good chance you ran as ssd @ x16 ,not x34 if you did not run something in the back ground to kick up the clock's in as ssd
-and that could knock down the 4k's.
-open up cpu-z and run as ssd again.
-if it runs at x16 during the bench turn off the down clocking .
