Guys, I'm considering changin my automation server's system drive from a single IDE/PATA drive to two SATA drives in a RAID1 configuration - becuase I need the redundancy RAID1 gives becuase I don't like downtime, and I may get deployed for up to a year next summer (leaving the wife alone with the PC), so I really need the reliability.
Anyway, how much of a true perfomance gain is there in going from a 7200 rpm PATA drive to a 7200 RPM SATA drive, or to a 10000RPM SATA drive.
Can any of those drives even approach the specs for the interfaces (100 or 133MB/sec for PATA and 150MB/sec for SATA). In actual use, without resorting to one of the RAID striping methods, is there going to be any real performance increase in going from the lowest priced PATA drive to the highest price (per MB) SATA drive.
The drives are system drives, so size is not important.
1. I can get 40MB 7200RPM SATA drives with 2MB buffers for $40/each
2. I can get the same with 8MB buffers for $55/each
3. I can get 36.7GB 10000RPM SATA drives with 8MB buffers for $85/each refurbbed and $110/each new.
The warranty on option 2 and the non-refurbed option 3 are 3-5 years (I think 1 year for option 1).
Also, in a RAID1 setup, if one HDD goes kaput, will the array work off the 1 good drive, without intervention, until the bad one is replaced?
