can i have a 5400 RPM Harddisk and another 7200+ RPM Haddisk together connected to a motherboard..? will it be faster when i access data from 7200+ RPM harddisk than of 5200 RPM harddisk..? thanks in advance RMPL
It should be faster to access the 7200rpm drive but the 5400rpm drive is probably of a lower ata anyway so it will slow your 7200rpm drive down. ie the data transfer will be the same. tbh You will never get the full speed the drives are capable of anyway. Ive got a 7200rpm ata100 and a 5400rpm ata66 and they both transfer data at about 40mb/s. Even if I disconnect the slow drive the ata100 drive runs at 40mb/s. Its quite good really, 40mb/s on a ata66 drive will do me! Incidently my ata133 only runs at 30mb/s Overall, I suppose what im saying is that in theory the 5400rpm drive should slow your other drive down, but probably wont! Do some benchmarks. I cant remember the names of any decent freeware hdd benchmark programs, I just use sandra most of the time. I dont think sandra is that good, but its a benchmark!
HD Tach is a good benchmark for hard drives. Thanks to various advances, newer hard drives will be faster in general. Larger caches, higher platter density and other techniques in new drives might have a 5400RPM drive of today besting a 7200RPM drive of several years ago. The 5400RPM drive will not affect the 7200RPM drive. Now, depending on the limitations of your motherboard, that could be a factor. Additionally, if you were attempting a RAID array with the drives, that wouldn't be ideal. As two standalone drives, there won't be any issues. The 7200RPM will be faster. Weather your motherboard is capable of those maximum transfer speeds is another story.
