Hi all!

I have two Samsung 840 128gb PRO ssd's in RAID 0, but I am not very happy with the acces times and the 4K-speeds.
Please look at the AS SSD benchmark below:



My rig:

HP Z400 Workstation
X58 chipset
Xeon W3680 (getting oc'ed soon)
12gb DDR3 1333 RAM
LSI 9266-4i Raid controller (with CacheVault)
2x Samsung 840 pro 128gb
Windows 8 Pro (clean install)

Raid configuration:
Raid 0 @ 165 gb (I have left 72gb for OP)
Strip size: 32 kb
Read Policy: Always Read Ahead
Write Policy: Write Back with BBU
IO Policy: Direct IO
Acces Policy: Read Write

I really hope someone can give me some advice about bringing down the acces time(s).

Thanks!

Ok,

I have changed the Read policy to No Read Ahead and I have set the EnablePreFetcher to zero which showed some improvements:



I think I will try the Fastpath software next.

I assume the latency is caused by the RAID controller so not much can be done about it.

Howdy all,

Got around to benchmarking my 128GB 840 Pros in RAID0 now that I've reinstalled Win 7 and gotten a nice, stable overclock. How are these numbers, overall?



I am a touch peeved in that I get an error when I run the benchmark that stops it from performing one of the functions. Is there perhaps a setting I can adjust that is know to cause this problem?

Thanks,
JML

You can have these results on 4.5ghz and c-states disable:

But you would probably have to get rid of enterprise Intel RST 3.6 and install only 11.2. and if you already didnt do it flash modded OROM into bios so that TRIM works on X79 with Raid field.

My scores seem a bit low, but maybe its because its on a laptop.





The Read/Write IOPS are looking very low - kinda curious as to why.
