*NEW* 150Gb Raptors

Single 150GB Raptor...

Wups, had firefox and some services running during Winbench 99.

It's a lot quieter than I thought. When idle, I can't hear it above the fans which are set to low. When seeking, it can be heard but it's not too loud. Runs slightly warmer than my Hitachi's but not by much.

This is an HDtach of 2 x 74GB Raptors in RAID0 on an Intel ICH5R controller, stripe 32KB, cluster 4KB, motherboard is an Asus P4P800 E Deluxe:

I would have thought 2 x 150GB Raptors in RAID0 would have given a higher Average Read in HDTach?

Damn, those Intel controllers are amazing!!! My 16K stripe gets lower than that! I have heard they are better than the nVRAID though, so I shouldn't be too surprised.

3000th POST - WOOOOOO!!!
 
Since the 150GB Raptor got announced I'm slightly peeved off. But, is it really worth getting rid of my single 74GB Raptor?

Early reviews of the 150GB Raptor doesn't really suggest it's THAT much faster or for me to get rid of my 74GB Raptor for the new 150GB Raptor, bearing in mind that my Raptor is mainly used for booting windows up...

It would be just as pointful to get another 74gb and raid them as it would be to get a 150.
 
makes me angry knowing that poeple will spend the extra on somthing (gaming raptor) that they may only ever see once, which is when they take it out of the box. If you got a clear case or a window case with a clear view to the drive and your into tarting your pc up then (get a life) thats fine buy one.
Dont get me wrong I like the look of it but WHY!

When i upgrade my cpu i hope the heatspreader has a nice picture on it........

LOL :D. I know - I got the server version. What a waste of half the MTBF and a good £30.

Nice average read of 76Mb/s here! A good 5-10mb/s up on the 74GB raptor. TBH, it looks like I'm going to be selling my 74GB raptor RAID and run 1 HDU again, especially when it feels just as fast as the RAID.

So whats the best stripe size then plz, ive got something majorly wrong with my raptors if you people are getting 200+ Burst speed :(


THIS IS THE LINK, CAUSE THUMBNAIL BROKE :S , SOZ :)

Have you used a controller on the PCI bus - in which case that would explain the low burst and fluctuating read.

EDIT: Just checked your mobo - the RAID sata ports run on the PCI-Express lanes - weird - most likely a poor controller.

Thanks very much :D

Do you know which is the best raid controller plz ?

No, sorry, I looked at the wrong chipset - apparently the RAID controller runs through PCI-express but it is most likely limited by a poor chipset, though I'm not really sure.

What a strange board. The SATA RAID runs off the ULi 1567 chipset on the Hypertransport link to the main chipset, the ULi 1695. Now the 1567 is a pants chipset but was designed to run the AGP portion and the PCI bus - so perhaps it is on the PCI bus - I just can't tell!!! You could try picking up a SATAII PCI express x1 controller card with RAID (I picked a decent one the other day for £20 - it will be delivered tomorrow and see if it works - in any event, it has SATAII, NCQ and RAID0,1 so even if you figure out which bus the SATA RAID inbuilt on your board runs off, you won't be losing out as this does SATAII RAID, not only SATA1.

The rule of thumb regarding stripe to cluster size is, the stripe size should be no more than 4 Xs your cluster size, so if you have a cluster size of 4KBs (Windows XP default), then your stripe size should be no nore than 16KBs.

Personally, I have a stripe size of 32KBs and a cluster size of 4KBs, I find this works very well for me, I do quite a bit of video work, some gaming.

I found that the bigger stripe sizes ie 64KBs, 128KBs did not give me the same performance, either in benchmarks or in real work! ;)
 
I dont know whether, To order, A new Abit AN8 Motherboard, and see if that speeds up my HDD Speed, or get a Pci Raid Controller,

Im quite annoyed that i get such a low speed, :(
 
Looking at the graphs mine looks quite poor. As this is the first time I have used this tool what could be slowing mine down?
*EDIT Cant insert image*

So the burst speed shows only 137mb/s
Random Access 8.1
CPU utilization 2%
Average read 75.6
