I have 2, I agree with them. Get another drive and run a RAID 0+1.

If I were to use 0+1 would I have to get a RAID controller?

Performance increases linearly as far as I know. 3 in RAID 0 are 3 times faster than one drive (apart from the SATA raid controller overhead that decreases the speed a bit). RAID 0+1 is for who cares about 100% data integrity WITHOUT doing backups. On my home PC I have games, pictures and music, all of them backed up on DVDs. If my HDD fails, I'll be upset, but in the end all that I have to do is to reinstall WIN on another HDD, and that's it. RAID 0+1 - no way.

I've seen you have a WD 160 GB, and I'm searching for a silent 160GB HDD to RAID 0. How is yours doing while searching? Is it above or below the ambient noise?

Cheers!

Diminishing returns... Generically and assuming a good controller
1 HD = 100%
2 HDs = 180%
3 HDs = 220%
4 HDs = 260%

There will always be an overheard of transferring the data, buffering, etc. RAID0 just reduces the time waiting for the head finding a sector. It only helps with one part of the process of reading/writing data.

And is the performance between RAID0 and 0+1 pretty similar?

How is he supposed to do RAID0+1 with 3 drives?

Where is this information from? It sounds about right based upon the fact that my 4 HDDs give me 210% performance on the southbridge, but it would be nice to know where you got that from.

Made the numbers up to illustrate a point! They are guesstimates.

Isn't that backwards? RAID0 does not decrease seek time (which is what I'm assuming you mean by finding a sector), but it increases the speed at which data can be read/written. Correct me if I am wrong...
