2 200 gig drives in raid 0 or 1 300 gig

Which would be better for me to do. I would get two common SATA 7200 rpm drive at 200gigs and set them up for raid 0. Or for about the same price I could get a Maxtor 300 gig 16mb cache SATA drive. Which setup would be better and I'd be losing about 100 gigs if I did the first combo in raid but that really doesn't make a big difference to me considering both are very large drives.
 
Actually, wouldn't you GAIN 100GB by putting 2x200 in RAID 0 vs 1x300

If you're going for speed, not worth it

In fact, just get 2x200GB, and operate them separately

uhh, lets do some math

2x200GB = 400GB

1x300GB = 300GB

400GB - 300GB = 100GB

2x 200gig = 400gig
1x 300gig - 300gig

Raid 0 means you are just stripping the data accross both drives (non parity), and therefore are getting the full 400gigs. The point of this is basically just speed (although its pretty minimal with 2 drives).

Raid 1 will put copies of the data on both drives, so if one fails you still have your data. That would only give you 200gigs total space since it needs to make 2 copies of everything.
 
Oh my bad alright. - so then the final question would be is it worth getting the Maxtor with the 16 gig cache versus the Western Digital with the 8mb cache?
 
np 🙂

You were just thinking of Raid 1, which you WILL only get the amount of space that your smallest drive in the array has available.

Raid 0 is just stripping.
