[QUOTE=debro;2535037]In a laptop? You honestly believe that those tiny little 2.5" platters rotating at 5400rpm with an 8MB cache are going to outperform a 3.5" HDD at 10K rpm with 32MB cache …[/QUOTE]
No a 2.5" hdd at 5400 cant replace a desktop drive, but what if you need the extra storage room, and speed is not that important? A bigger HDD should be able to do the job nicely.
[QUOTE=debro;2535037] Because I can’t help but notice that you either don’t understand, or haven’t bothered reading, my previous post. 3.5" HDD at 10K RPM will rarely stress Sata1.5Gb/s at full speed with sustained reads (large files). Improvements in BUFFERED speeds show improvements on sata3.0Gb/s, most HDD caches can’t provide enough bandwidth to transfer their entire contents at full speed on Sata6.0Gb/s Sata6.0Gb/s is overkill for desktop HDD’s (SSD’s are different). Suggesting that Sata6.0 is required on a 2.5" 5400RPM hdd is absolutely absurd. Your suggestion that the Sata6.0Gb/s interface will somehow speedup these slow 2.5" 5400rpm HDD’s is comparative to suggsting that gold coating a turd, will provide equivalent value of a solid gold bar the same size. I cannot stress this enough …[/QUOTE]
I agree that most drive hardly use all the sata1 bandwidth (unless they are in raid), but my main concern is the [B]Access time[/B], and the only hard drive that can make it disappears is an SSD.
Sata3 will be great with SSD drives, all the rest conventional hard drives will simply do the same job as they do now with sata2.
