HDD SSD
SATA 2.5" with max height of 9.5mm, minimal storage size 160GB (198 HDD models and 336 SSD models comply to that). Ofcourse if you externalise the harddrive there is a whole world of 3.5" drives that are larger in storage size and also cheaper to be gotten.
SSD can be used, but it seems that on the PS4 there is even less incentive (compared to PS3) to replace the drive for a SSD, best price/performance are still 7200rpm drives.

in this respect, it would be interesting to see the performance of the Western Digital Black-II WD1001x06xdtl which has 1TB of platter storage and 120GB of NAND SSD storage.
it is unsure if TRIM is enabled by default for UFS on the PS4, but on BSD in general it can be enabled with tune2fs -t enable : http://forums.freebsd.org/showthread.php?t=28004 see also : http://www.wonkity.com/~wblock/docs/html/ssd.html
Size
- the standard 500GB harddrive is actually 465.76 GiB as reported by Windows
- after some splitting in 15 partitions, a 420.12 GiB mainpartition is left for the user
- on that mainpartition 408 GB is useable for the user
