SATA RAID?

[Alex]

my mobo has onboard SATA RAID but i don't have any SATA HDs... 😛

(i have a 160gb 8mb cache maxtor and a 120gb 8mb cache WD)

i was thinking of maybe investing in one or more SATA HDs and trying to get a RAID 0 or 0+1 array going... what do you guys think?

will there be any significant performance increase over my current HDs?

i know that just switching to regular SATA won't be noticeable unless i get a 10krpm drive but maybe with raid....

eh?

Not even with RAID. It doesn't improve performance by too much, thought stuff "feels" to load faster.

Sorry, but as I always state RAID0 IS worth it to increase performance (and when appropriate precautions against data loss are taken).
For me it feels way faster and the synthetic benchmarks agree (53mb/s single disk vs. 93 mb/s 2 disks in RAID0).
Who does not like RAID0 can keep waiting ages until the FarCry level has loaded 😛

 

[Alex]

wow if those values are correct its a phenomenal performance increase!
i have a couple bucks to spend but i might need a new video card cause i think its dying... 🙁

I don't know what kind of disk gets 53mb/s, but I know most modern drives can beat that easily. 😕

This raid card is one o the few that seem worth it.

I think RAID0 systems tend to feel like they have less lag caused by the hard drive. I never actually benchmarked my RAID0 setup so I don't know if it's transfer rates are better, but it's performance under a load feels much more consistant. When several things are reading from it at once or reading and writing simultaneously it seems to keep up the pace much better than a single drive so if you have a backup strategy I recommend it.

It's the HD bench of the Sandra suite...I don't give too much about the actual numbers of synthetic benches, just the difference proofs the effect...
Drive(s) are Hitachi 7200/8MB SATA-II

Raid 0 will only show increased performance in susstained data transfer scenarios. If you're using it for every day use, and for gaming on occassion, you really won't see the difference. I have conventional SATA drives striped and Raptors striped, and while the benchmark #'s are nice, I've seen almost no performance gain in ANY game I play (FC included).

Sorry, it's already been proven by several articles that gaming performance is minisculy improved by a Raid 0 setup.

Any reasonable hard drive will outperform 53mb/s. EASILY.

As I said...it's just the synthetic sandra benchmark...get over it 😉
Besides I think this figures are quite reasonable, excluding lame burst effects out of the cache...remember, it is common agreement that controllers beyond ATA66 (mb/s) have only marginal performance impact...

EDIT: Just did some research 70mb/s is current top notch Barracuda 400/7200/8 w/ NCQ...Sysmark99 value...see? Other drives easily go far under that...now I have to find Sysmark99 somewhere to get comparable numbers 😀
