Need a new system for Vegas - any suggestions? - Page 3

Actually it is interesting thast you mention your laptop, because it was working on laptops (with the slow drives they tend to have) I was thinking of at the time I mentioned 5400 RPM drives. Dreadful working with them after being used to the desktop unit.

On the other hand you previously made the point you that most of us are using 7200 RPM drives and for most purposes they will suffice. And they will.

On the other hand there is a point of diminishing returns. I notice little difference running the new Velociraptors in RAID 0 vs non-Raid and I don't even run RAID any longer so as to have the additonal storage space. Additionally, the RAID controllers on my MOBO seem to be full of issues. I never experienced problems with RAID until I moved to integrated controllers during my last two PCs.

I have a few laptops and each of them has relatively zippy 7200 rpm drives. However, with the advent of perpendicular recording on new hard drives, which seriously increases the areal density and how much data is moving under the heads at a given rpm, even 5400 rpm drives these days can be significantly faster than an old longitudinal technology drive. There is also the whole issue of access time, which is where the Raptor, Velicoraptor and certain SCSI drives really excel. They can initially get to the data fast and, from that point, sustain a fairly high data rate. The Seagate 1.5TB drive has a higher sustained transfer rate than virtually anyting else available, due to its higher areal density, but its access times don't come anywhere near a WD Velicoraptor.
