How fast are the 150Gb Raptors?

My WD1500ADFD on it's own -

I'm pretty sure, reading a few things about the hard drives, that the burst speed means nothing, but the read speed and write speed is more important am I correct?

Either way, for me personally, my Samsung might be a bit slower on the Random Access part, but I really dont see the want to have one, because of the extra speed?? I just personally dont think its worth the extra cash :( I mean for example, what would two 80Gb SATA drives manage in comparison?

Hey if you don't want it, then don't get it! If it ain't worth it for you and the cash is worth more to you then more power to ya. :)

Oversimplifying a little perhaps, but there are primarily 2 aspects to drive parameters that make a substantial difference to the perceived speed of a hard-drive: 1) sustained transfer rate and 2) random access time.

The thing to remember is that each of these affect performance differently, which means that in some situations having more of 1) will increase perceived speed while 2) won't matter so much (e.g. when loading large files such as BF2 maps on a defragmented drive so the reading is dominated by transfer rather than accessing/moving the heads) while in other situations having more of 2) (or rather, less of 2)) will increase perceived performance while 1) will possibly matter less depending how much random access is happening (e.g. when booting, loading a complicated app with many dll's, or otherwise while working with a large number of smaller files at once, or generally when your filesystem is fragmented and/or you have multiple programs doing disk IO at the same time.) You can improve 1) by RAID0'ing disks, but there's no way to improve 2), other than by buying a faster disk.
 
I'm loving my 2x 150GB Raptors in RAID 0 :cool:

Definitely worth the cost to me but then I do a lot of stuff which generates high IO. Always the first in BF2 maps too.
 
I'd never touch another drive again.

Ordered a 150GB Raptor to go with my Vista OEM earlier today.

The only downside to these drives is their noise, apart from that, they are well worth the money.
 
Yeah they are quite loud but only when they're seeking.

4x 7200.10's in raid 0 would be more likely to fail and have higher seek times.

As I have a 74Gb Raptor at the moment, is there anywhere that I could get a decent second hand one that I could put the two together and see the differences for myself?

I used to own SCSI (I still do I just dont have the hardware as its lent to a 'friend' and I've yet to have it back!! :lol:) but I found with all the cables and adaptors I had to have, it drove me mental. Drives where kinda noisy but god they where quick.

I think seeing things 'in your face' is worth it, as if you can see a difference then thats all the better, if you cant see a difference, then there's no point to having it.

Its one of the reasons I wont be buying a new graphics card until I buy my two 24" TFT screens for my PC's as I wont benifit as such from a faster graphics card than my X1900 XT. I know there are faster cards out there, but at the moment, mines doing just fine :)

accod - do you have any tests that you've done with one raptor and then the other?? If so, please could you post them up for me? I'd like to see the differences...
 
There are loads of threads on here with benchmark results. See the 2nd post in this one for results very similar to mine. Thats with two drives. I haven't tried benchmarking a single drive but heres someone elses benchmark:

I have two of the 74GB Raptors with the 16MB cache in a RAID 0 array. They fly, get around 145MB/sec in HD Tach. Moving aorund large files really is very quick, which is the main reason I bought them as I have huge number of high res images that I often need to move around.
