Can my 9 yr old Dell XPS 8100 PC support a new sata III drive

provlima · Aug 31, 2017

I have to replace my old hdd on my 9 year old Dell XPS 8100. The desktop has an i7 chip so I'd hate to replace it with a new i7 PC because they are expensive.

The bad drive is an sata drive. I notice that current crop of hdd's seem to be sata III drives. Will the old Dell PC mother board on the desktop support the new sata III drives

If I replace the bad hard drive would I be able to restore the W7 OS and all my data by using a macrium
backup file on the desktops external backup drive?

Thanks for your help!

It will support any revision of SATA, if you are buying a SSD that is SATA 3 but you only have SATA 2 ports it will work jsut not run at full speed, however for HDD's that wont matter as they dont go that fast.

For a hard drive, the difference between sata II and III is minimal.
It refers to the hard drive buffer to sata transfer rate.
But, hard drive performance is determined mostly by the mechanical and rotation characteristics.
As far as it goes, your plan is fine.

But... Consider this as an opportunity to go to a ssd for your windows C drive.

Thanks for your reply...the oem sata drive I am replacing has no suffix designation so I take it was before sata II or sata III
generations. Would that make a difference?

For a mechanical HDD little (like 1% or less) to no difference, and it will work just fine. There is really no reason for mechanical HDD's to be beyond SATA 2 for the interface (mostly just marketing), as there are none that can sustain speeds faster than 300MB/s.
