sata or sata II?

[footballdude2k3]

whats the difference?

 

[Geoff]

SATA = 1.5Gbps
SATAII = 3.0Gbps

ah thanks, ok now, since nothing is really that big right now, does it really matter or is it just, oh my sata is better than yours?

Nope he has 4 SATA2 HDDs in RAID 0 (striping). Over all capacity of space and quicker write/read times. Only problem with that is...

When one sector on one of the disks fails, however, the corresponding sector on every other disk is rendered useless because part of the data is now corrupted. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss.

Also whether you have a SATA or SATA2 motherboard, get a SATA2 drive, It will work on a normal SATA motherboard but only at 1.5Gbps.

with the HDs out right now, i think the SATA2 is not as useful as it could be because you can't even transfer at the speed of 1.5gbps, let alone 3.0

pretty much every hd on the market today is sata 2.
they don't cost more and they don't really perform better...
not much use to them i guess

not really. at least 1/3 of them are still sold with IDE interface

Mine came with a tiny little jumper that limited it to 1.5GB/S. I had to get it out with a thumb tack.

WOW ide still exists

but what i was comparing sata 2 to sata. not ide

yeah i really don't get why they make a jumper that would limit the transfer rate

yup IDE are still for sale, and at the same price as SATA too

To make sure all boards with the older SATA can also talk to the harddive

Which is why I perform almost daily backups

I would go with a SATAII hard drive if you are buying one new, as they are about the same price, offer a bit better performance (especially in burst speed tests which spike over 150MBps).

They do that because if your SATA connector on your mainboard is SATA1 and not SATA2 then you need to set the jumper to lower the transfer rate, in order to use the drive.

even without setting the jumper limit on the HD, i thought it would still be backwards compatible. if the HD is able to transfer up to 3gbps, and the mobo only allows, 1.5gbps, the wouldn't the 1.5gbps be the limiting factor? or would that mean that the HD will not be read at all?

when purchasing a SATA cable at microcenter i've seen some that are rated 1.5 Gbps and some that are 3.0 Gbps. marketing scheme?

In a perfect world, it should work like that. But the rumours say that it doesn't
