Velociraptor

[shueardm]

Anybody done any benching with WD Velociraptor hard drives?
I've just sold a workstation doing 340MB/s on 8 older WD 3200YS drives and want to match or better that, maybe with fewer drives. How many would do that in RAID 5, maybe 6?

Mark that is what I run, try them in Raid 0 with a good raid card, raid 5 is not for performance, very quick drives, but a bit dear.

10,000 RPM = more heat, shorter life.

Try the Seagate 7200.11 1.5TB drives, those drives (from reading reviews) can do 100MB/sec per drive! More bang for your buck.

Also max is 3.0Gbps via SATA II which equals to 384MB/sec.

Nothing compared to Raptors for speed, also they come with a 5yr warranty the others don't

[shueardm]

Are they noisy? My old Raptor was very noisy.

[swsw1550]

Not really mate, once they settle in a bit.

The retail seagates have 5 year warranty. Don't forget that the Velocis give you less space.

But 20% more throughput.

Do yourself a favour Stormdave, buy a couple 10,000RPM drives then tell me you don't notice any difference with them, Very Very quick compared to 7200RPM drives, I have been using 10,000RPM drives for years and there is no way I would go back to 7200rpm drives, sorry.

P.S the only down fall is the B***dy Price of them.

I have allways in the past "raptors"..... one for for "sys-disk", and a second for "pagefile.sys"

now in the last selfbuilding WS, I assembling the new " VelociRaptor WD1500GLFS" ...so I can compare between the "old" and the "new"
the new 2,5" disk in the 3,5" adapter for cooling is a dream

extremely more quiet (as the old)

extremely cooler (as the old) ...... it is the sys-disk, and (per Everest) he is cooler as all other disk in the WS
he is cooler as the >save for AutoCad< disk etc., they are only "on" but have no funktion in a NLE-session.

4,2 or 4,5 ms is not a big difference

big difference runs with max ~125MB to min ~80MB.... (the old ~80 down to ~ 45)

Attention: the are two body versions from Western Digital VelociRaptor aviable.
old with WD1500GLFS >> the connectors not compatible for 3,5" backplanes or removable disk without carrier
new with WD1500HLFS >> the connectors are compatible for 3,5" backplanes or removable disk without carrier

friendly greetings from europe\austria\vienna ....old (but not morbid) Hans ;-)

That is the correct way to setup any computer, always run the page file on a seprate disk, also if you have more than 8GB of ram you can turn of the page file all together and then you will notice some difference in speed, this also depends on some applications though.

Thank you for that information Hans. I'm glad they are cooler & quieter, they needed to be.

I am getting 420MB/sec with 4 x Seagate NS Sata II 750GB 24/7 drives in Raid0, they have 5 year warranty

I think there is not that much point in going even faster because it may take off

[swsw1550]

Yes Anton, they may take off to the clouds.

how would turning off the swap file affect software that won't work if it can't detect the swap file?

or is that no longer an issue with Vista 64?
