Fitting a hdd drive inside pc tower with a pci card?

A stick is compact but, until they come with 500GB sticks, methinks I'll stick to the HDDs. I keep a clone of the SDD in my notebook on one so, if the SSD goes completely belly up, I can pull the clone out of the enclosure and pop it into the notebook. The other HDD has images of the OS partitions, the recovery partition, and the data partition so I can easily restore the SSD if it should ever go wonky. I backup any data I generate while on the road to the clone HDD using FreeFileSync. Since the added data is confined to a single folder, it is easy to transfer the data to my desktop when I get home.

Thanks all.I notice that one of you use FreeFileSyncWould you say that is better than the one I use.It's the microsoft sync toy maybe it would be beeter for me I only use it to save documents photo's etc to another drive

Many Thanks once again.

If you are comfortable and satisfied with SyncToy, I would just stay with it. I feel FreeFileSync is better for me than SyncToy because it has the option to send deleted files to a versioning folder.

Thank You very much all.
