Inspiron 1501 Sata Chipset Question
I'm looking to upgrade my Hard Drive on my Inspiron 1501 Notebook. Currently it has a Hitatchi 5400 SATA/150 80GB. I want to upgrade it to SATA/300 but I don't know if I will get the SATA/300 performance... I know it will work (backwards compat spec) but if I'm not going to get the performance, then it means nothing to me. The support docs don't mention anything about it (thanks Dell).
A lot of the 1501 documentation seems outdated so I take anything that says with a grain of salt anyhow (i.e. only supports 2GB RAM which is untrue for my laptop).
If anyone has any information on this, that would be great.
Thanks
- Ryan

Even a 7200 rpm drive - regardless of interface - can't sustain more than 70 MBps, which is less than half of what SATA 150 can support. Translation: for a single hard drive, there's no difference in performance between SATA 150 and SATA 3G; the drive mechanism limits performance, not the interface type.
