If you read our article on Plextor's Xtreme firmware for the M5P (http://www.cdrlabs.com/Reviews/plextor- ... mware.html), we mentioned that there would be some changes to the hardware when the actual M5 Pro Xtreme shipped. Plextor has now released some more details. Sorry.. its in Japanese.

Here are the main points:
- NAND flash chips are now a TSOP package (pins along the shorter edges) instead of BGA
- TSOP package has a maximum page size of 16KB vs 8KB with the BGA. This supposedly gives the drive better "buffer management"
- TSOP has better heat dissipation so thermal pads are no longer needed
- PCB has been updated to support TSOP
