They need to be "trained" before files are stored in the NAND cache, which means you can't use one as a scratch disk, for example. It's only $120 or so for a 60/64GB SSD and a 1TB HDD, and you can get a 120/128GB SSD for around $90 (so $150 for the pair). It'll use an extra SATA port, but you'll be able to use the flash memory more effectively and get better performance from both the flash memory and magnetic hard disks with the specialized drives. Plus, you'll never run into issues with the OS handling the cache (apparently SSHDs don't work as well as they should in Windows 7).
I read comment and someone said the 1TB desktop SSHD of seagate has 8GB SSD in it. For my local price, the different between the cheapest seagate 1TB and this SSHD is around US $29 different. $29 for 8GB SSD is very expensive. If I buy ADATA Premier Pro SP900 64GB 2.5" SATA3 6Gb/s (Solid State Drive, SSD), my local price is $63.5 US dollars, make much more sense.
I still have a pretty new laptop with 500GB, still have a lot of space, just take me sometimes to transfer file to there.
