At what point will my harddrive be the slowest component in my system?

By bbsysadmin ·
I'm building a computer and so far my specs are:

Dell T7500 workstation
Genuine Windows(R) 7 Professional 64bit
Intel(R) Xeon(R) X5570 2.93GHz/8MB L3 Cache/6.4GT/s
12GB (6x2GB) DDR3 RDIMM Memory, 1333MHz, ECC
320GB SATA (7200RPM) Hard Disk Drive
1GB PCIe x16 nVidia Quadro FX3800, DisplayPort,DVI Capable

The computer will mostly be used for graphic design with CS4 and CS5 when it's released and I'm wondering if I should get a 10k SATA or need to step up to a 15K SAS drive? Or would a RAID0 SATA config be ok? Redundancy is not important

I'm a rich American, and I'd have to think twice about spending that much.

WHOA, that is a machine. I think that it will be fine if its only using CS4. We have High End Dual Cores with the same speed Hard Drive, 512Mb Graphics cards and 4GB of RAM and it seems to run our CAD products quite fine which I think use a fair bit more resources then CS4.

I guess it does depend on the image in question tho doesnt it.

Thanks,

Here the speed of the drives isn't as important

As the Cache on the HDD. Ideally the bigger the cache the faster the system send and gets data off the HDD.

So a 15K Drive with 1 MEG of Cache will not appear to be as fast as a 5400 RPM Drive with 8 MEG of Cache.

But if ti was me personally I would look for a better system to base my critical system on. Dell doesn't use great M'Boards they are just OK not good or great. A Gigabyte or Tyan M'Board would be my starting point here. They are just far more reliable.

No way to get around it - everything in a computer is always going to be faster than disk access.

But consider OH Smeg's post, certainly. You want fastest I/O, which will not necessarily coincide with highest RPM.

Maybe I'm not too far off with my 10,000 rpm Raptor of just 75GB?

Very cool!

hmmm... I gues I'll have to price up a couple of them, didn't realise hard disks were so crucial in overall speed, lesson learned.
Thanks to all who posted.
