Yes you can have a Mix of ATA and SATA. I do in my computer.
Read the advertisement very carefully, I've seen some really weasel wordings that imply one thing and completely mean another.
If no software that can be expensive to buy. There are no good free BluRay movie player software.
Before buying read user reviews on a site such as Newegg or amazon on the drive make & model itself.
Consider getting a BluRay burner. However it needs to be a current still being sold model. Nothing more useless than a old can't use most modern blanks drive. I use a Pioneer BDR-206Bk and it burns 4x Verbatim at 4X and 6X blanks at 6X and it would burn faster if I let it.
OTOH the 10X LG I replaced with the Pioneer was finicky about brand of BD-R media and burned most at 2X even though they were rated faster. I can use cheap discs from a spindle in the Pioneer for testing my BluRay movie authoring before burning to the Good Quality Verbatims with no problems. In the LG they just turned out as coasters.
