10k raptor vs raid 0 sata2?

post #1 of 22
Thread Starter 
sata 2 is cheeper, but is it faster with the 3gbps transfer? or is this a way to target idiots like me?

the 10k raptors are always reviewed as fast, but does it have any major drawbacks?

i am stumped

The 3GBPS does not matter... since no hard drive gets even close to that kind of bandwidth.... Heck, most even don't get close to the limits of the 1.5gbps of sata1... even in RAID.

Ok, here we go:

RAID0 advantages:
- Better bandwidth/average read performance
- cheaper, esp. in terms of cost per GB
- much more storage space

Raptor advantages:
- better access times, thus better performance with small files
- slightly more secure, since failure of one of the disks in RAID0 means total data loss.

Personally, I prefer the RAID0, since failure rates of modern hard drives are not that high, and the bandwidth/cost factors win it for me.

I think you can get the raptors in sata 2 as well. though myself I haven't seen what the hubbub is with them. they spin at 10k rpms and have quick access times but data transfer seems to be roughly the same speed you get nowhere near the storage for the price so to me it isn't worth it but I could be wrong.

There are no SATAII Raptors as far as I know. And again, it does not matter. doesn't even get close to using all that theoretical bandwidth.

The Raptors are all about access time. The hard drive responds much quicker than any other hard drive. To me it is essential because I can't stand that extra wait.

Yes, the throughput is on par with other PMR drives now.

Now the Sata 1.5Gb/3Gb bandwidth... you don't need to worry about that unless you are using 12 of them in a system.

If you want the fastest drive, go with the Raptor. If you wanna be above the rest (like me) go with multiple Raptors in a stripe.

really though 4.2 vs 9ms is it really that much difference?

4ms is twice as fast as 9ms

But yeah it makes a differance, depending on what you do will determine how much you notice it.

can that small little number at such a small time anyway really make that much of a difference?
