Wendell, Do these really work / make sense?

Its an adapter that you mount and plug your SSD into a PCI-E card. It's like 30 bucks but will there be a tangable benefit from actually using a product like this? or is that Potential Bottleneck from the SATA interface still going to be there?

That seems just too good to be true somehow. I would like to see the results or facts about this.

It won't improve speed at all.

This is effectively an add-in SATA controller that you just so happen to be able to mount a drive on. There is a big difference between PCI-e based SSD's and SATA and the controllers on them. You can't magically by pass the SATA controller in the SSD to "unlock" its maximum potential.

It will be an PCI-e SSD but it will only run at SATA speeds. Not only that but it is on a "PCI-Express with transfer rate 5Gb/s Full Duplex channel" which will be slower than actually just connecting the drive to the SATA on the board. (providing you are connecting to SATA3 (6Gbps))

Yea it's just like the new M.2 drives that are starting to come out.  Most of them are Sata based and not native pcie.  

A good thing to remember is that if it is still using Sata it is still limited to Sata speeds.
