What would be the fastest?

-> SCSI 4 HDDs at 10000RPM RAID0?
-> SATA 4 HDDs at 10000TPM RAID0?

and with RAID0, what's the chance that 1 of the 4 new hdds die within a year?

And I'm still stuck with 20 MB/s.

/dev/hda:
Timing buffered disk reads: 84 MB in 3.06 seconds = 27.46 MB/sec

Maxtor 4D080H4
80 Gigabytes. Dont know much else about it. But its pretty good..Right?

i just installed a new 80GB seagate today:

Timing buffered disk reads: 166 MB in 3.01 seconds = 55.18 MB/sec

if that's a 7200rpm you might want to check your hdparm settings, NewbGhost. you should probably be getting at least somewhere in the 40s i would think. ? also don't be doing stuff while running the benchmark (esp. media).

/dev/hda:
Timing buffered disk reads: 104 MB in 3.05 seconds = 34.07 MB/sec

After shutting down XMMS. Also I dont believe it is 7200rpm. It's about 3 yrs old, thinking its 5600? Or the common one in the 5000s. That one. I think. Also it has some problems right now, needs a full format soon.

/dev/hda:
Timing buffered disk reads: 164 MB in 3.02 seconds = 54.33 MB/sec
/dev/hdb:
Timing buffered disk reads: 168 MB in 3.02 seconds = 55.69 MB/sec
Two identical Seagate 80Gb Barracuda 7200rpm drives.

Wonder what drive and interface is the fastest? I have seen a few IDEs that are faster than SCSI.

Anybody answer that question? Maybe someone who has a server at work or something.

my hard-drives are both running in udma5 mode, (which i presume is the fastest). at first i thought my performance was pretty bad, but i guess not. btw, anyway who's drives are running ~5MB/s or less, make sure you are running in DMA mode, makes a huge difference. i can't tell you exactly how to do that, you *might* have to recompile the kernel, maybe not if you're lucky. anyway, here's my numbers:

Western Digital 100gig (WDC WD1000JB-00CRA0):
Timing buffered disk reads: 110 MB in 3.01 seconds = 36.54 MB/sec

Maxtor 80gig (Maxtor 4W080H6):
Timing buffered disk reads: 58 MB in 3.01 seconds = 19.27 MB/sec

so there you have it. DMA is awesome, Maxtor is not.

err.. my Maxtor 80 gig (6Y080L0) gives me:

And that's with only a 2mb cache instead of the 8 that is now standard....

As for the fastest performance, i think 55-60 is the absolute fastest you can go with a conventional ide drive (not raid). Although I have yet to see any drives break 58.

Here's my specs, only on the drive with Slack on it;
Maxtor ide 80gb 7000 rpm

dev/hdb:
Timing buffered disk reads: 166 MB in 3.00 seconds = 55.33 MB/sec

Primary disc, 40gb Western Digital
/dev/discs/disc0/disc:
Timing buffered disk reads: 64 MB in 2.47 seconds = 25.89 MB/sec

Secondary disc, 160gb Seagate:
/dev/discs/disc1/disc:
Timing buffered disk reads: 64 MB in 1.17 seconds = 54.85 MB/sec

iRiver iHP-120:
/dev/discs/disc2/disc:
Timing buffered disk reads: 64 MB in 5.74 seconds = 11.15 MB/sec

maxtors are bad-ass fast. my 40GB maxtor with 2mb cache:

/dev/hdb:
Timing buffered disk reads: 64 MB in 1.11 seconds = 57.66 MB/sec

If you don't mind, which kernel are you running? Is it patched? What mobo?

These are 2 Maxtor 7200 rpm 2MB cache drives. Kernel 2.4.26, with
/dev/hda being Windoze plus Linux swap, and
/dev/hdc being Linux.

believe it or not, that was 2.4.20, on an epox 8K3A+ i think with overclocked athlon xp 1600+. glory days!

>edit:
i just reinstalled my maxtor, taking out the seagate to use in my other box for some video editing. the score is basically the same, though, this time with 2.6.8.1 and an epox 8RDA+. 40gb maxtor diamondmax 8, 2mb cache. i thought it was all marketing hype, but maybe ata133 does provide some miniscule performance boost after all. ?

[4] root:/home/sero # hdparm -Tt /dev/hda

/dev/hda:
Timing cached reads: 1976 MB in 2.00 seconds = 987.16 MB/sec
Timing buffered disk reads: 174 MB in 3.02 seconds = 57.61 MB/sec

Maxtor 40gb 2mb buffer IDE 72000rpm
/dev/hda:
Timing buffered disk reads: 170 MB in 3.00 seconds = 56.67 MB/sec

Western Digital 80gb 8mb buffer IDE 72000rpm
/dev/hdb:
Timing buffered disk reads: 164 MB in 3.00 seconds = 54.67 MB/sec


Maxtor pulls out with a win!!!
