(used 64k stripe/default cluster)
Whats optimal stripe/cluster for games?

Post your HD Tach runs.

theres mine! -> and a few others :-p

64/16 or 32/16 works for me very good :)

[cirthix]

sequential and burst speeds are only part of the performance of a disk/raid. random accesses are far more important.

[SerialSniper]

Yeah but for better random access you need physically faster hard drives (10K,15K+ rpm, like raptors). And they cost alot of $$$.

2 x 7200.10 320GB
128kb stripe
RAID 0

[SEE attachment]

I need another one of these drives. They're pretty good.

depends on what you are doing.


For loading games, fast transfer rates are key.

[k0nsl]

Does anybody have 3 x 7200.10 320GB drives in RAID0. I might buy another one, but it depends...

They're great drives and very cheap too :)

[SerialSniper]

I have 1 as storage/backup and might get another to go in another raid 0 after seeing your results.

960GB is alot of space lol but 3 should perform really well!

[bing]

Seagate 7200.10 250GB x 2 at el-cheapo & humbly rig using onboard built-in ICH Intel Matrix Raid 0.

Can't afford those expensive Raptor, so I use this two babies monster that cost me only $170 for both. :)

Rig & the Raid 0 DETAIL (http://www.ocforums.com/showthread.php?t=467848) , plus validated result in PCMark05 : Score = 4062 (http://service.futuremark.com/compare?pcm05=421782) :ROTF:

Yes....yes....I know, those "burst speed" right ? Just check at the supplied DETAIL above.

The CPU, Memory, FSB and GFX result are sux ! :yawn:
Please don't puke, just look at those harddisk related stuffs in PCMark05 result, fyi this is a "value / grannie grade" rig, nuthing special. :rolleyes:

Looking at the performance/price ratio, not bad eh ? Say compared to Raptor ! :D

Burst Speed is insane! :slobber: Nice one bing!
So thats the cache?

I will read into the Intel Matrix thing as I don't really know what its all about.

EDIT: Also just noticed the Ramdom acces time, close to a raptor ;)

[NapalmV5]

tomorrow ill be getting 1GB cache upgrade to my areca 1230 and will do some benching.. :)

Thx, yep I think so, though burst speed doesn't reflect the disk's true performance, this kind of number is common with Intel south bridge ICH chip as Raid controller when used with the latest SATA 3GBps drive.

Fyi, my XP boot time is approx. 10-11 seconds (approx. 3.5 revolutions at the XP boot scrolling blue bar) . ;)

Some nice easy reading here -> Intel: What is Matrix RAID? (http://www.intel.com/support/chipsets/imsm/sb/CS-020681.htm) or this for two physical disks Intel: Matrix RAID (Two Volumes Per Array) (http://www.intel.com/support/chipsets/imst/sb/cs-012525.htm)

dats just how consistent HD Tach is.. sometimes 3000+MB/s bursts..

6x 74 16MB raptors, NCQ/TCQ + read/write cache enabled on Areca ARC1230

2 bad don have another 6 raptors to truly test.. oh well.. :)

[Nanometer]

It must install windows in 2 minutes.. lol Very nice. Perhaps my next upgrade is 4 raptors as well, too bad I wouldn't notice it enough to be worth it.

[NapalmV5]

tnx.. im close to 2 mins.. waitin on nnstep to finish of the XS os..

stay tuned ill be getting 2 more raptors so, well see how dat goes.. :)

I dunno but that seems really low compared to you guys :(

[syne_24]

Nice, I'm going to get my hands on an Areca 1210 soon :)

hdd has pretty much nothing to do with how long it take to install xp. i can install xp in 6min and i have a single crappy drive.

[NapalmV5]

m0da, it does that when running the long bench..
