Piggyback PCB for mSATA SSDs?

Hi,

does anyone know whether this sort of tiny hardware is in the works? Thinking about a small PCB with mSATA connector with an ultra short flexible SATA cable on the one side and a port to the GPIO pins on the other (using VCC-3V3 from there -- given there's enough power on Pins 1/17). Since mSATA SSDs are available with up to 1 TB these days and aren't that expensive compared to 2.5" SSDs this would be a fantastic accessory automagically 'compatible' with all existing case solutions.

Only the 3.3V voltage might be a problem if there's not enough power on the GPIO pins providing 3.3V?
Hello friend. I just got a industrial grade SSD card from RENICE. The performance is amazing.                       
And they're now presenting some free CF, SD cards and SSD to Twitter followers http://goo.gl/o9we1A

Performance isn't an issue since the SATA port in the A20 SoC (or the drivers) seems to be the limitation. On Banana Pi I managed to get 48 MB/sec write and 120 MB/sec read with small record sizes after setting the CPU governor to performance:

  3. 1024000      32   48182   47776   116355   117078
  4. 1024000     512   47506   47094   111864   111329
  5. 1024000   16384   47164   47056   113732   112668
Copy the Code
(measured via "iozone -a -g 1000m -s 1000m -i 0 -i 1 -r 4|32|512|16384K"). And these values are pretty good compared to other A20-based boards, eg. https://groups.google.com/forum/#!topic/cubieboard/7R4HlCDNCTU

Just to give an impression how such an mSATA solution would fit on the back of the BananaPi:



(mSATA-SSDs are 50.80mm x 29.85mm in size)
