SATA300 drives on SATA150 connections

[stud]

Hi All,

I've had serious issues with hard drives of late, all of which have been SATA150. In trying to find a quiet drive, I've bumped into the Samsung 250GB SATA300 drive. Will this work on a SATA150 connection? - I'm thinking it's all backwards compatible.

Cheers

yeah there prefectly backwards compatible but it will only work at sata150 speeds

Yes it will You won't see any different in speed apart from burst rate.

I believe the Samsungs have a jumper you need to set to force SATA150 speeds?

Thanks for the replies - I'll be getting an SATA300 drive then. I understand it will work at SATA150 speeds, but perhaps headroom later on in another PC. More importantly than speed are the other developments with these drives I think.

SATA300 was basically for Port multiplier that allows you to connect multiple harddrives to a single SATA port. SATA300's advantage over SATA150 is less than 0.5%. Current generation of harddrives are happy on UDMA100
