What kind of controller you got? You need to select the max. file size in ATTO (256MB) so get correct numbers. If the file size is too low, your controller's just gonna do cached reads/writes. And if your controller features 512MB or more cache you won't see any normal results even mit 256MB filesize ;)Quote:

@Carpe^Diem: Great result, can't wait to see how my 5405 performs with 4x1TB Samsung F1's :)
Gotta love these controllers, how did you cool yours? Mine's under water, see sig, lol :rolleyes:
@jcool
Yeah... these controllers get very hot. It's not possible to let it run 24/7 passive. I got a 120mm fan on it from the side, and then i get temps about 54-54 degrees celcius.
What waterblock did you get to fit on it ?
24/7 passive? Mine ran 5 minutes until it started beeping and triggered an overheat warning :lol:
For the waterclock just click my sig (wonder why no one ever does that...)
Sorry mate.. my german are not that good :)
Could you link me to the waterblock that you use ?
I dunno how you guys are getting such amazing results from them hard drives.. i get just shy of 500mB/sec with 3 sas drives.. can any recommend anything i've done wrong?

You haven't done anything wrong... When you see burstspeeds at 3000mb/s it is "fake", its the new onboard controller from Intel showing real nice figures, but they cant be transfered to real-life performance
what about the average read rateQuote:

To your signature :D 3x146GB Cheetah SAS 15K.5 @ 500mB/sec (yes megabytes) naaa, your cache burstspeed is around 500mb/s, not your sustained!
got me all excited =P
as long as it's running hella fast for me in the real world, that's al that really matters anyways

Wow :D nice Rubycon.. very nice indeed !

Really nice speed there Rubycon. :up:
here's my storage raid.
6x Seagate Barracuda 7200.11 500 GB running RAID 5 with block size 64kb on a Areca 1220 256MB cache controller. I know, I should have picked 128 but it's a bit to late now ;)
All tests done on a Opteron 175.. I accidentally killed my mobo the other day :( but I have a new one on the way. doubt there will be any difference in test results though

HD Tach is a bit funny at the end there, not sure why but ohh well.. I'm happy with my speed. sorta..
Has anyone heard of "Battleship Mtron"? This crazy dude tried to run a 9x stripe raid using Mtron SSD's :shocked::shocked:
Reading that article it's easy to see that myself and many others here are limited by the controller's capabilities and with a faster controller we could have obtained much better results.. Say, anyone know if it's possible to OC a Areca 1220 card? :D:DQuote:
This means our old controller had us capped at 400 MB/s throughput and took away an extra 200 MB/s of un-tapped power from the Mtron units. However, knowing in my head my full intentions of achieving close to 1 GB/s throughput with 9 or 10 drives, I did some research on the Areca 1231ML as well. It turns out not too many people really have this kind of problem using current generation mechanical HDD's. Single consumer level raid controllers are not usually meant to be scaling at 800 to 1000 MB/s sustained throughput. But, the only information I could find on the 1231ML led me to believe it runs out of steam right around 800 MB/s.

Not bad at all ;)
Notice how the HDTach curve is a little weird, I think that's because the OS can't handle partitions over 2TB, that's why it splits at 2048GB <-> rest.
Raid 5 is currently building (that's what I'm gonna use, obviously), with 1,8TB it's just shy of the 2TB barrier, which means I can forget about the max. partition size issue.. for now ;)
for comparison: 5400 rpm, 60GB, 2.5" sata laptop drive
:eek:
If i'm buying a new HDD, with all this data you guys have collected, which is the best recommendation? I want the fastest HDD setup for games & OS.
the western digital 640s are looking pretty good

Just 1 WD6400AAKS
2 x 640 Western Digital drives.
ICR9 - OS volume - 100 Gigs, extra space set as another partition.
128k stripe.
no changes to HDtune, default test.
I like that it just seems to get faster the more the test ran, not slower.
and look at that access time, thats faster then most 2 raptor set ups.
gonna test a few more ways to make this nice and fast.
That is indeed quite impressive! What OS is that btw?Quote:
