Ive got a Seagate 500GB Thin SSHD.
500GB spinning disk, with 8GB MLC NAND cache, and a little voodoo mixed in to make it work without any setup/intervention.
Its a 2.5inch laptop form factor, thin 7mm z-height, SATA.
It's from a Dell thats been upgraded to full SSD storage.

Application load times, Booting OS, and game load times are about 3x faster than a regular HDD. So it has tangible benefits.
If nobody wants it I might use it as an intermediate storage tier between my SSD's and HDD's particularly for game loading.
Looking for $20.
Pickup in Tauranga, or shipping could be arranged.
