SATA 300?

[Touareg]

If I purchase SATA drives today (ie. Raptor 74 gigs), will they run at SATA 300 sometime in the future if plugged into a SATA 300 controller?

Thanks!

I don't think they will....kind of like ATA100 won't run at ATA133 on an ATA133 channel.

 

[Touareg]

Oh well.... it was a nice thought anyway.

Thanks

Nothing will probably be up to snuff to really make use of SATA300. Only RAID-0 Raptors have breached 150MB/s as it is.

Which means it still doesn't matter b/c each cable gets 150MB/s so we still have to wait until a single drive can break the speed.

Yes, it will. SATA standards are designed to be backwards compatible. There's a pretty good chance that SATA I drives won't work on SAS controllers, but they will work on SATA II controllers.

They won't run at 300, but the SATA 300 will be backwards compatible. It doesn't really matter, so don't worry about it. The main limit for hard drives is the mechanics. I'd like to see an ATA100 or 133 drive sustain over 70MB/s transfer. Basically not gonna happen yet.

It would be a waste of money. There isn't a drive on the market these days that even comes close to 150. Serial ATA is a real con job right now. Have you noticed how all of the specs say "up to 150 MB/sec? There isn't a manufacturer out there that is listing the true specifications for their drives and controllers.

SATA II will support more than one drive per cable, so all the extra bandwidth won't necessarily go to waste. By the time it is released, 2 highend drives will likely be able to saturate SATA I at peak throughput.

high end such as a ramdrive

If you can chain 3 drives, then you'd need 225MB/s to handle them, which is more than SATA's 150MB/s.

Hell, a Raptor that has a peak of 74MB/s, if used on a SATA-II daisy chain with another Raptor would suck up 150MB/s bandwidth, so you're at the limit if you only have 2 drivers per chain, and even if the limit was 150MB/s, burst rates for the Raptor might mean it coul dexceed the available bandwidth, so 150MB/s SATA would be a bottleneck

We will probably start getting better rates when they start adding gobs of ram to the hard drives (like 32M +). Already getting drives with 8M and I think there is a toshiba laptop drive with 16.

Thanx for saving me the effort. Happy holidays to everyone.
