How to find version of SATA controller?
Looking at WesternDigital's website, the older SATA controllers do not use autospeed negotiation hence I am wondering if fitting faster drive (7200 vs 5400 rpm) will be of benefit .... although this "autospeed negotiation " may refer to data transfer as opposed to data transfer.
So how do I find out the chipset or version of my SATA controller?
FYI, These First Generation Serial ATA (SATA I) controllers include the following chipsets:
- VT8237
- VT8237R
- VT6420
- VT6421L
- SIS760
- SIS964

dell latitude e6400 bought new in 2009, so can't imagine it was manufactured earlier than 2008.
running vista - 32 bit
looking in device manager,
computer: ACPI x86-based PC
IDE ATA/ATAPI controllers (presumably that is he hared disc controller? : Ricoh SD/MMC Host Controller
Storage controllers: Intel ICH8M-E/ICH9m-E SATA RAID controller
Microsoft iSCSI Initator
.... doesn't mean a lot to me and doesn't aswer me question :(

As you posted yourself already, your system has the Intel ICH8/ICH9 chipset, so the concerns about the speed are irrelevant as they are only for when you're using those few VIA or SIS chipsets/sata controllers.

briliant thanks.
more searching reveals that my current hard drive, WD 80 GB scorpio blue, WD5000BEVT, is specc'ed to run at
so the scropio black should be a driect plug in replacement.
I am assuming the the device driver is displaying the correct part as I have yet to peek inside the lappy.
thanks to all who replied, seems I can go ahead and buy and swap.

Just remember that buffer to host is meaningless - the real indicator of performance is platter to buffer - which will be about 70 MBps max.
