Will SATA-II drives work in a regular SATA board?

[The Pentium Guy]

Argh, stupid question I know. Will a SATA-II drive work on a board that doesn't support SATA-II?

Reason I'm asking is beucase I know for a fact that, for example, NCQ can be switched on or off - so is it possible for the drive to operate in (regular) SATA mode?

After searching, I got a thumbsup - but can someone quickly confirm this?

yes backwards compatible, but the other way around? but yeah they work, but i think at SATA speeds, so ur better of w/ a plain SATA w/ NCQ

Thanks,
But see the thing is, the 16MB Buffered drives are only SATA-II. Besides, I don't beleive those drives even use all the available bandwidth of SATA even.

theoretically the peak bandwidth can be used when reading from the buffer.

SATA and SATAII are forwards and backwards compatible. The buffer isn't part of the SATA spec.

i thought maxtor still made 16mb cache sata 1 drives

SATA II drives are backwards compatible and will work with a SATA connection. My burst rate with my SATA II drive is actualy higher than what SATA can get, I get a burst rate of 167mb/s with my western digital 8mb cache SATA II drive.

Gotcha.

Woah.

Maxline III 250GB.
Looks like they even have an ATA133 drive that has a 16MB buffer... I'll be buying this.

I do a lot of I/O intensive work such as programming, and I need a fast drive without going overly expensive. I know maxtors are said "not to be reliable", but I've got a harddrive enclosure, and I back up my data frequently. 5 year warantee too indicates that there may be a change in quality.

Or maybe that (DM10 200GB)

Wtf 167mbps?! Can RAID 0'd Raptors even get that kind of speed?

 

[stevty2889]

My 36gb raptors in raid-0 get a burst rate of 174mb/s, the 74gb versions probably get slightly higher. Thats just the burst rate after all, sustained rate of my SATA II drive is 56mb/s compared to 73mb/s of the raid-0 raptors.

Uhh I have a Seagate 7200.8 (SATA I + NCQ) with a DFI LanParty NF4 Ultra-D (SATA II compliant) and so I get SATA speeds. You do NOT need anything above SATA speeds because SATA is not even using its full capabilities yet.

NCQ slows you down like a b!tch, so turn it off.

I've seen burst speeds of 150MB/sec in Windows. Raptors are kind iffy right now considering they lose in a lot of real world tests. Don't bash me, but I have read tons of benchmarks. They rock the house with their 5.2ms seek times and 10k rpm especially in synthetic tests, but if you put them in some game loading tests/multitasking scenarios, they get owned.
