Raptor > nForce 4 RAID

[Zak33]

OK....synthetic's its not as fast, but in real life....

Raptor's Rock

No facts...no figures.....it just is!

They almost make you wish Raptors were a woman

[Zak33]

and these are fairly quiet in comparison

[Clunk]

is this the single raptor vs the seagate raid 0 contest that you mentioned in the other thread?

i have a couple of questions

how does the heat from the seagates compare with the heat from a raptor (under load)

and how about noise? is the raptor more noisy than the 2 seagates?

quiet compared to a woman? lol

I need more raptors...

^^ I don't
(currently got a Seagate ST318406LW and a Maxtor Atlas 15k 36WLS- SCSI of course )

[Zak33]

right....lets answer Clunk.

Heat, this raptor is much hotter than one Seagate, but that maybe because the heatsink it has is doing a much better job. Those Seagates got hotter and hotter, and this drive gets hot fast and stays like it. It weighs a lot more and the case/heatsin is far closer to my old SCSI stuff than the Seagates. So while it feels hotter faster, that's prolly good as it's distributing the heat. HOWEVER I have a large fan blowing between my hard drives so, they're always fine.

Noise: those 2 Seagates were impossible ot hear....even full load. My Tagan PSU is the loudest thing in my system, by far.

I can just hear the Raptor, when it's loading stuff up. Never ever heard the Seagates.

Raw boot speed it awesome. Apart from BIOS going through faster, as RAID has extra stuff to run through, the actual process of XP booting is much faster.

From power button to running is 33 seconds (Opteron at 2.2 at the mo) and the load wheel turns less than twice Raid was 43 seconds and turned 4 times.

It is an addiction for sure..

ohh..gotta do figures anyway

From my last tests (one SATA Seagate and then in RAID)

Single Disk:
Random Access Time : 13.6 ms (this is a lot slower than my previous 10k SCSI disks)
Average Read Speed: 64.3 mb/s (this is a lot FASTER than my previous 10k SCSI drives)
Burst Speed: 254mb/s (this is so fast I nearly expired at it!!...but it is right on BOTH drives )

RAID 0, 2 identical drives, striped. Option in nForce RAID setup for largest striping blokc of 128k for performance use)
Random Access Time: 13.9 ms (tad slower than single disk)
Average Read Speed: 126mb/s (now IL-2 will load faster )
Burst Speed: 196mb/s (big drop off but still waaaaay faster than my SCSI stuff was)

and now I'm pleased to say the single Seagate is still identical to those fiugures....

so......Raptor?

[Zak33]

Random Access Time : 7.5 ms
Average Read Speed: 66 mb/s
Burst Speed: 127mb/s

These Raptors are SATA 150, and frankly, its irrelevent. This system is loading IL-2 SO MUCH FASTER than either the single or RAID Seagates.

It's also faster than my SCSI stuff was

Happy boy....
I've now got one of the Seagates as a data drive, keeping my main drive cleaner and defragged, and the other is going into an external hard drive enclosure from Scan....the plan all along was to see if RAID was worthy, and if not, to get a Raptor (like David the boss told me to do in the first place ) and to use the two SATA Seagates as I am now.

He was right....he alway bloody is

[ExceededGoku]

Zak you are annoying me, now I'm going to have to get a Raptor >

[Nox]

Random Access Time : 7.5 ms
Average Read Speed: 66 mb/s
Burst Speed: 127mb/s

hmmm, your average read seems kinda low, I know they tail off, but even still...

and you still got a ways to go to catch my burst

nm, 66 being average isn't much below what I was thinking.

[Clunk]

thanks for the answers Zak. im going to see if i can dig up a second hand one

[Zak33]

seems ebay is good for them at the mo.

Stick with 74gb or higher...not 36's..they're still good, but not as dense in the platters for data, so not as fast.
