Which is why I like the idea of the Momentus line from Seagate. It's an HDD (e.g. 500 GBB, 7200rpm) coupled with an SSD (e.g. 4GB), with the SSD taking care of frequently read files (or sectors, however that works internally), and the HDD taking care of infrequently read files and all write ops. If it could also be used as a non-volatile cache for write ops, it'd be even better.
Pricing is not too particularly competitive compared to buying a HDD 500GB + SSD 32GB together, but it does have the advantage of taking up only one 2.5" slot and having the logic described above offered on-board, instead of having to deal with that in software somehow (i.e. installing your operating system non-statically across two volumes in a transparent manner to itself).
