HI,
So I`ve successfully over-clocked me CPU. Me system be fast, but I figure th' slowest part now be access t' an' from hard drives.

I`ve heard o' RAID, an' me limited understandin' be that RAID 0 uses 2 identical drives (say 1TB) an' writes one bit o' information t' one an' th' next bit o' info t' th' other, so 2 hard drives act like one drive. th' size o' both drives only shows as 1TB still but 'tis much quicker?

Now if i sailed' an' bought 2 x http://www.amazon.co.uk/Hitachi-De [...] 638&sr=8-2 ... an' RAID 0 them, then will I notice a big difference if i put me OS on them an' th' main programs I use. Will this make a significant speed increase in Windows bootin' up an' things like unzippin' or PARin' files?

Be thar a specific type o' hard drive i ortin' ta use?

Does th' buffer size o' th' hard drive make much difference?

Be th' speed gain double?

Why would ere use an expensive Raptor drive (10,000rpm) if I can get a drive wi' a 32MB buffer (7200rpm) that might run nearly as fast?

Do i need t' use a special cable t' join them together?

Do i need special software?

Be 't done through th' BIOS, if so 't it fairly straght fore?

Thank you
Ya scurvy dog!

Alrighty Jack,

How much are you looking to spend on your two drives?

I went to raid 5 with sataII80 GB drives for my OS and APPS and honestly dont really seem much improvment.

In a quick easy to understand summary.....

raid 0 is for speed - writes to both HDs alternatively - 2 x 1TB drives would give 2 TB storage
raid 1 is for data security - backs up drive 1 on drive 2 - 2 x 1TB gives 1 TB storage
raid 5 is a bit of both - I have 3 drives installed. 2 to give raid 0 and one extra to get data recovery on a drive failure. so 3 x 1TB drives would give 2 TB storage.

Raid needs to be supported by motherboard (or a pci card I suppose). No fancy cables. Need drivers which are normally on the motherboard disk to be installed via floppy or usb during install. Think you would need a fresh windows install and raid setup before installing windows.

In summary would recommend buying a small SSD for you OS and a larger normal drive for your data. Although I haven't tried it it will be my next step. Should be much faster, cooler, quieter.

U spent a lot of time adding your accent into your question, or do you just type with an accent?
