for comparison here is the linear read test - same 680i nvraid (not 3520) but 4x16gb mtron's -
2x x25-Es get A LOT more IOPS than 8 mtrons.
To the OP - passmark is easy to set up to test randoms (advanced HDD tests), but I am not sure how it tests things... i.e. I am not sure if cache will fool it or not.
tests like these:

I still really doubt that. I'm afraid we'll never know unless he can get IOmeter running...
lol I am not making a blind statement FYI. 2x mtrons in R0 get 30MB/s in mixed writes/reads (one of the standard passmark HDD tests) and 2x X25-Es get 270MB/s in the same benchmark. A normal HDD gets ~3MB/s. I've done A LOT of research before I got my 2 x25-es
Old tech doesn't compare to new tech.

Either way, still nice setups guys!
But I gotta agree with One_Hertz here; everything I've seen would suggest way more IOPS with x25-e; Although it will vary with block size and queue depth, the pattern is consistent across different settings.
Here is some single drive IOMETER data on ICH9R (have a look at the links for more, and different block sizes; also you there are other comparable tests on other SSD's there if you dig around)
MOBI 3000
X25-E
x25e on ICH9R

MOBI 3500 on ICH9R

Have a look at the individual IOMeter results for single drive. There is no way that RAID0 can get >100% scaling per additional drive. (So if we compared apples to apples on the same controller, 2*X25-E in RAID0 should have way more IOPS than 8*MOBI 3000 (FYI the newer MOBI 3500 have about 1/2 the IOPS as the MOBI 3000, but slightly higher STR values; those testing results are in another thread if you look)

That workstation pattern? Or Server? I guess you are right then... crazy on the Iops. Still, I'd love to have the throughput of that setup more![]()
Throughput means absolutely nothing. Companies don't even bother making their SSDs actually fast, instead they try to increase the throughput so people like you buy their slow SSDs. I don't even look at that figure anymore. It is much more useless than even 3dmark scores for GPUs.
I agree with you both; it really depends on what you are doing/what apps are being used. I think it's important to look at the whole picture.
But too much emphasis is placed on HDtune/HDtach because it's easy and convenient to test. But if you had to look at 1 test that tells you the most information, it would be the complete battery of tests from IOMeter. It will tell you everything that that HDtune/HDtach will tell you and much, much more.
jcool - "workstation" pattern for IOMeter is defined as 8KB / 80%read / 80% random
If you are working with uncompressed 1080p material that doesn't fit your ram - you can never have enough throughput...
Well what he has would be just enough to edit 1 large file + host the OS/favourite apps. Ofc you'll need a Raid 5/6/10/50/whatever with mechanical drives to work with as well, which is what I use now. Just saying it would be cool to have both (for me).

i expect better from you one_hertz
exactly
thats smtg forgoten here @ storage subforum
well you guys put too much emphasis on IOPs..
higher IOPs dont mean sheat @ real world apps
4x ssd = 8x adfd raptor
when:
the more the faster the merrier
and you guys put too much emphasis on benches where cpu/ram/mobo/os greatly influences the results
Good morning, I'm back.
Finished ocing my new memory so back on the SSD topic.
I flashed my Highpoint RR 3520 to the new firmware and tested all the different blocksizes - found that 256 was the best.
Resulted in a little improved performance - see below - 8x16GB Mtron Mobi's in Raid 0 on Highpoint RR 3520 IOP341 PCI-E card![]()
Informational note - one of the eight mtron drives is a 3500 (the others are mobi 3000s).
I'm sure that is hurting me - but how much? Hard to tell.
EDIT - removed incorrect Crystal Disk Mark (too small, run out of controller cache).
Your crystalmark is set at 100MB, which means you are testing the controller's cache. Set it to 1000MB to test your array (I think your cache is 256MB).
I have no idea why your performance test scores are so low, they shouldn't be. Try 100% sequential with 16MB blocks 100% reads with IOmeter and see what sequential rates that shows; it should show similar rates to hdtune. Maybe performance test is just gimped... works for me though. As far as I remember it shows 450MB/s reads 300MB/s writes and 270MB/s rs+rw for me.
You can't compare the IOPS of your setup with a raid card to a single x25-e on onboard controller. If you take my setup 2 X25Es on adaptec 5405 I get ~3k IOPs in that test, over 2x higher.
