As some of us know there is an update for the old-timer :)
Link to download
Test performed on a used drive. (X58 Gigabyte UD7, slightly PCIe OC'd)
AS SSD using 02HD (oldfirmware)
Attachment 111601
using 02M3 (new)
Attachment 111602
I'll do a test shortly using the Intel P67 6Gb/s ports.
P67 (ASUS P8P67 Deluxe, no PCIe OC)
Using the 6Gb/s Intel ports.

According to CDM it's pretty close to 50K iops at 4KB random reads.
I'll do a quick iometer test...
Thanks Anvil. I was thinking of updating my ICH9, but by the looks of it there is no need to rush.
There is no reason to rush, at least not for the 6Gb/s ports using 3Gb/s drives.
I'll do one more test using the standard 3Gb/s ports.
Part of the difference might be due to my PCIe OC on the X58 platform. (105-107 iirc)
iometer showed 47-48' iops using 1 worker and 49' using 4 workers.
There are of course other reasons to go for SB (mainstream) but for power users I'd say wait for the workstation chipset.
The 2600K is a fun processor and for multimedia stuff it's a great upgrade, especially compared to the 6XXX/9XXX processors.
This is with 3x Intel X25m G2 with the new firmware

I think the new ASSSD has change dthe scoring system?
Not sure. Your 4K performance is pretty low, for some reason, though.Quote:

Your score is low due to the 4K-64 Threads part of AS SSD.
Did you install RST and enable write cache?
It still doesn't explain why the read score is so low.
All fixedQuote:

I turned off Windows write-cache buffer flushing
also ran ccleaner and free space cleaner with FF
Not sure what fixed it. But I'm happy now :)
Great score, seems like you got it sorted :)
2R0 Intel G2 160GB RST 10.0.0.1046
First run
Attachment 111618
Pretty good score, the score using 02HD would have been ~730
edit:
833 is more than I ever got using 2R0 Vertex LE, very close though.

Although I've found AS SSD to be inconsistent, after doing about 10 runs I've concluded the newer firmware reduced write performance for me using my raid 0 setup.
10 runs of AS SSD would reduce performance on most SSDs :), each run equals ~3GB of writes.
You can't blame the inconsistent scores solely on AS SSD, it should be fairly consistent with the exception of drives using compression.
The are a lot of factors that leads to inconsistent results while benchmarking SSDs, the SSD itself is not consistent + background tasks,..
It looks like your using 64KB or 128KB strip size?
I've found 16-32KB to be more consistent in raid, sequentials slow down a bit using smaller strips but there aren't that many operations that utilizes the seq. bandwidth of 2-3 SSDs.
(with the exception of copy operations, in the end most operations are random and random performance is great using smaller strips)
Next time youre cleaning the drives you might consider trying a smaller strip size, it might not suit you but it's worth a try.

3R0 X25-M G2 160GB 02M3 (secure erased)
Attachment 111620
Don't expect getting close to "secure erased" benchmark results while running OS on the drives :)
I've tested different strip sizes and all around 128 proved to be most effective for my needs.
This install is less than a week old and was securely erased. As far as 10 runs tangiblely effecting performance I haven't seen that myself. I've noticed my sequential and random write numbers vary with as sdd by 5-15 MBs run to run. Cdm seems more consistent but I still appreciate that they are both useful tests.
Well, for sure my eyes can see that 4K-64thrd have been improved....let them rest for a while and bench in 3-4 days....to get more results....
Thanks for the heads up, Anvil.
For those of us running the Kingston-branded X25-V drives it appears that Telnet @ overclock.net has already hacked this release to work with our drives.
Not working on my sig rig unfortunately.
I presume this is because the drives are in an array however I do not know this for a fact. :shrug:
Not inclined to tackle it tonight since the OS lives there.
The G2 in my lappy flashed fine.
The G1 firmware version included with this release is unchanged (I'm still running a G1 in a cruncher.)
I saw virtually no change:

The main change is 4K at high queue depths, nothing spectacular/noticeable has happened wrt sequentials.
It does look like max latency might have improved, during iometer testing I didn't find the usual spikes.
A few P67 results.

doesnt CBM write like 15gb per run?Quote:
Cdm seems more consistent but I still appreciate that they are both useful tests.
Anvil can you run 4R0 again with 128k stripe?
thanks for the insight anvil
@mezcal,
I've got a few Kingstons as well, maybe I'll give it a go.
I checked one of the drives and it had only 64GB host writes :p:
Time to put it into use before it gets out-of-date.
Depends on the SSD, it does write a lot.Quote:

I do concentrate on small strips, 8KB-32KB, but I'll see what I can do :)Quote:

So, I seldom look at the sequential figures, they are far above whats needed anyway.
My numbers seem lower than most here.
I am running an ASROCK X58 Extreme & i7 950 stock while using the onboard intel ICH10 Raid controller.
All the drives have the newest firmware and were secure erased and fresh load of Win 7 64bit SP1 was loaded right before the test. Stripe size is 128k and performance is the same if I have Write Cache Buffer Flushing on or off.
Any ideas?
thanks
Your score looks pretty good to me.
The 80GB drives are somewhat limited in write vs the 160GB and that should largely cover for the lower score.
Lowering the strip size to 16KB might bring a few more points, not sure if it's worth it though.
edit:
Can you verify that you have the Write Back Cache Enabled.
(The WBC is enabled using the Intel Rapid Storage Technology or "IRST or RST" for short)
WOO HOO.
Thanks Anvil - that did the trick - I knew there was some setting I was missing.
New scores
Just added a 4th drive and all my numbers went up except Seq. Read went down :eek: - this is using the onboard ICH10 on an ASROCK X58 Extreme.
Yeah, thats pretty normal.
Odd number of drives does (for the most) perform better sequentially than even numbers, using the ICH/PCH that is.
Looks like 3 is the magic number for my setup - will off this 4th drive and go with 3 for now.
Thanks for the heads up Anvil.
