New SATA 300 mps HD's? Twice the speed!

John_Dumke · 04-20-2005, 11:43 PM

Has anybody read any info on the new standard improving SATA from 150 mps to 300 mps.

I need about 800 gigs to 1 TB, but didn't want to upgrade (from 500 gigs) if new drives are coming out soon.

Assuming the Motherboard is compatible will these drives be much faster, and will larger drives (250 - 400 gigs) be available in the new 300 mps format?

While I have heard that them called SATA II, I have read that the II designation is just the organization specifications that SATA manufacturers need to adhear to (now or previously called SATA IO). So I think the correct terminology for the new SATA format is SATA 300.

Thanks, John

SATA 300 mean it can handle up to that speed does not mean the harddrives will acturally go that speed. acturally the best performance hardrive right now for large storage is the maxtor hardrive which feature 16MB of chache.

I haven't seen any of the drives yet but there are suppose to be some controllers capable of SATA300 on the market right now. SATAII just adds NCQ to the standard. I'd doubt if you will ever see a drive capable of 300MB/s. I haven't seen a drive break 100MB/s sustain transfer speed yet.

Never say never Joe.

not right now joe but probably in the future there will be much faster operating hdds.

So what I hear people saying is that even though the new standard doubles the potential throughput and even though new drives may be SATA 300, hard drive speed has not increased significantly along with the new spec. So waiting for a new set of faster hard drives won't produce results anytime soon.

I'm not saying never. Just don't get your hopes up soon.
As of today the fastest sustained transfer speed I have seen is from a Seagate SCSI drive @ 142MB/s. For SATA, WD Raptor @ 72MB/s which is still only half of the interface transfer speed. Unless they find a magic disk and magic read/write head, true HD 300MB/s transfer speed will be a long way off.
You could get a HD with a larger cache. This would optimize the interface transfer speed.
