| 7200RPM SATA2 or 10KRPM SATA1
I am not entirely sure as to the performance difference between a Harddrive that is 7200RPM but SATA 2 (3.0Gb/s) versus a harddrive that was 10,000RPM at SATA 1 (1.5Gb/s).I have not found any harddrives at 10,000RPM but use SATA2.
In which case would the 10,000 RPM be better than the SATA 2 drive? Vis Versa?
Thanks

| The new Raptor is 10K RPM and SATA2. Spendy tho. $300 for 300GB.
SATA1 vs SATA2 in itself doesn't mean much. The SATA2 bus has theoretically higher throughput but not even SATA1 drives reach the potential of the SATA1 bus.
The benchmarks I've seen on the drive are not much higher than the Western Digital WD6400AAKS which is 640GB and not much more than $100. |

Yeah I know drives rarely reach their rated transfer speed.I have 2 SATA 1 drives in RAID 0 (which theoretically should near double performance) but usually get around 1.2 GB/s so they are not even going as fast as one should by itself - but I know the numbers I am getting are normal and expected.
Would the same thing be expected of SATA 2? Would they be more in the neighborhood of say 1.5 or 1.6 Gb/s? And again... which means better - highier RPM or throughput? I am sure one is better for certain applications so which? |

| Nope. The determining factor is almost always the drive, and not the interface. If you have a SATA1 drive, chances are good it can't do more than 100 MB/s sustained, but 70 - 80 MB/s is where most tops out. As far as I know, virtually all drives that are capable of faster than 100 MB/s all SATA2. The one exception I know of is the i-RAM, but that's a DRAM based SSD, not a magnetic storage. |
