I've got a 5400 rpm drive and a 7200 rpm drive. I recently ran some benchmarks, and the 5400 drive (maxtor 27 gb ata/66) gets only 2500 kb/s for reading and writing, while the 7200 rpm drive (seagate 80 gb barracuda) gets 40,000 kb/s reading and 16 kb/s. I know at 5400 rpm it should be slower, but this seems a little too slow. When I boot up my computer reports the drive is in LBA/ATA-66 mode, but in Windows XP the device manager says the Primary IDE Master is using PIO Mode (doesn't say what number), even though I have it set on "Use DMA if available." Is there anything I can do to speed up my drive?
