WD, a Western Digital company and world leader in storage and connected-life products, today announced it is shipping the world's first ultra-slim 2.5-inch, 5 mm hard drives and solid state hybrid drives (SSHD), which are designed for integration into the slimmest devices and space-constrained computing environments. With 500 GB of storage capacity and models with high performance-enabling solid state hybrid drive technology, this slim product line helps to address the tradeoffs system designers often make between capacity, physical size and performance.

Seagate has 8GB on both their models (laptop and desktop version). I will jump on a leg here , and guess the competition will gravitate around that number as of current moment: http://www.seagate.com/files/www-co...docs/laptop-sshd-datasheet-1784-1-1302-us.pdf

What I don't like is they pair the flash to 5400rpm drive. Basically everything that is cached out of that flash runs on the slower speed. I don't understand why not pair it with 7200rpm?

Not entirely correct - the 750 GB Seagate Momentus XT variants are 16 GB NAND flash....

What model #? Everything from Seagate indicates only 8 GB on the 750 GB Momentus XT.
Sorry, You are right.
First gen was 4 gb and second gen is 8 gb

5400rpm drives have improved on speed a lot over the last few years and am betting that with the most accessed stuff cached on the flash that this will be somewhat quicker than comparable 7200rpm drives of the same size.
