Since I'm not a hdd guru, I'm having a little problem. In the next few days I want to buy a 200 Gb Western Digital on SATA 2, but the computer on which I plan to use it (Asrock K8NF3 mobo- a piece of s...) supports only SATA1. As much as I read on the internet and other forums there shouldn't be any compatibility problems because SATA 2 hdds have a jumper to switch them to run in SATA 1 mode. It's that true? I mean, does any of you actually did that and it's all "nice and pink"?
Thanks a lot for your help ! Cheers :D
 
Some HDDs have a jumper, others have a disk firmware modification utility to switch from SATA-I to SATA-II

Most SATA-II drives are sold with factory default settings set on SATA-I. So yes, it should work out of the box.

Well to be honest sataII isn't really an "established" protocol yet. Its just like plugging in a usb1 into a usb2.0. I've never heard of any jumpers needed on any other sataII drive, but then I'm still a greenhorn overall in Hard drives.

Personally I think the 16mb cache on the 250gig will have a greater impact on the speed of the HD than the sataII speeds will........

I've got 2 of these.....very nice drives :)

Run 2 of these in raid 0 and they are very close to single raptor performance in most real-world situations.
 
The 16 Mb of cache can have an even better effect IF it's coupled with SATA-II (meaning 300 Mb/s + command queueing). The effect on a 8 Mb cache is quite impressive, I dare say it'd be great on a bigger cached disk.

Splendid

Hehe :-D

The NCQ and extra cache certainly helps but the interface itself doesn't even matter.

Some day when we've moved away from magnetic storage it will actually help ;-)
