Sata III, what is the point?

As ED hinted towards, solid state drives will saturate a SATA III connection already.Did you forget about modern SSDs?

Yeah how fast are those? 5 / 600Mbs Read / write?
Or are there drives that can run at 6Gbs?

Raw conversion of 6Gbs is 715.3 minus overhead and inefficiencies is about 500-600 MBs

Uh.. I think you don't quite get the limit of Sata III.. Sata II was limited to a 300 mb/s transfer rate.. But it's bandwidth was 3GBs.. Thus 6gbs = 600 mbs.. They're already pushing the boundary.. lol.

Have a quick read. It explains how it works. =).

Those read/writes are for specific file or data block sizes. The instantaneous rates while moving that data still varies, and like thideras pointed out, can still momentarily use all 6Gbps of a SATAIII connection. If those instantaneous rates were not that high, that drive would not reach 600Mbps total for a transfer.

Yep, HDDs probably will never be that fast.. but SSDs are already pushing the boundaries of SATAIII.
I personally thought SATAII was useless for the longest time... I only used it because it had a smaller cable than IDE did.

Well you have the details on overhead... here is a drive that clearly knocks out SATAII bandwidth.

many many others too.

Thats actually a pretty reasonable price!

I have a SSD in my hands right now that does ~540MB/s read speeds, almost double the max on SATA2
Must be nice to know people willing to send you SSDs to play with...

I was looking at those as well, but in the end I'm too much of a wuss with my data for sandforce drives. These will be the only drives in these machines so went the reliable stodgy route and got a couple Intel 320s. Even those are still monstrously faster than platter drives though. Really liking them

I got 160s with a giant rebate, so end up around $1 a gig.
Sandforce drives are usually faster but seem to have a little higher failure rate. If you're just using it for a boot drive and save data on another drive I definitely wouldn't worry about it. Mine are standalone drives so I have to.
Just read reviews on the exact drive you want before buying. Some particular ones, even in particular sizes, have oddly high failure rates

Noted, thanks
just a boot drive with games and software, all files and stuff will be on a mechanical drive
