Raptor 150s are noisy when searching - otherwise quiet.

Thats a RAID pair of 150s ^^.

Thats a pretty amazing result there mate.... :eek:

Any chance you can post a HD Tach screen grab please running flat out.

lay-z-boy · 17 Jul 2006 at 19:27

guys, remember hd tach means nothing for real world.

Even cheapo drives, ie 80gb hitachi could easily outperform raptors that have real world strip sizes (32-128k) with a 4k chunk size, you just try raiding something and having a very small chunk size.
But they would be much slower for real use.

However apart from game map loading, i havnt found anything that can measure, easily real world speed.

Here's one of my raptors lol, havn't got a HD tech graph tho.

What about transfer rates?

I disabled tagged queueing and it was another 10mb/s faster on burst speed.

Only 0.8mb/s faster on read speed though...

Put 4 of them in RAID 0 on an Areca 1220..... simply stunning.....

I just figure out how to set up RAID 0 with 2 hard drive but I have seen test where RAID 0 with 4 HD produce impressive IO result ( almost double 2 HD RAID 0, maybe RAID 0+0

). How is it possible. Is there a need for add in card or on board controller is enough.

Raid 0 is nice for performance buts its bad for fault tolerance. It quadruples the chances of loosing data due to a hardware fault, over four disks.

It'd be interesting to note how many members have actually had a RAID0 failure when using nice new disks.

Personally i did have a 36GB Raptor fail after only four months of ownership that knackered my 2 drive RAID0 array. I seem to remember not being best pleased at the time...

Whereabouts do you download this "Raptor Test" from?

noxidjkram@hotm · 4 Aug 2006 at 16:19

Tis HDTach - do a google....

What RAID controller are you using, I have 2 Raptors striped and i get an average read of 110 MB/s.

BTW, did you know those new I-Ram things have an average read of 130 MB/s, so your set-up is faster

Smiley Man · 4 Aug 2006 at 18:10

access time is what its all about :cool:

if only the PCI bus wasnt in the way

jbloggs · 4 Aug 2006 at 20:56

2 x 74GB Raptors (8MB cache WD740GD-00FLA2) in RAID0 on ICH5R controller:

The 16MB, I think, does give a good improvement over the 8MB cache, although the 8MB are certainly no slouches.

nForce3 onboard.

My mobo is PCI, so i would be limited by an add on card.

I've actually sold one of my Raptors now tho - and am selling the other. I'm off to Oz and prefer the cash.
