Hi,

The smaller 20gb version of this, HTC424020F7AT00 is less dense and very
inexpensive.

Would that suffice?

You'd be unhappy with the write cycle longevity of a flash drive for 
regular use anyway. Flash and super dense mag drives seem fine for use
if write/erase only happens occasionally (i.e. embedded/mp3 etc...)

The next step:

I've seen was from M-Systems - now sandisk.

http://www.sandisk.com/OEM/ProductCatalog(1335)-SSD_formerly_FFD_UATA_25.aspx

Still not with write/erase longevity as a decent spinning drive. 




Now they(sandisk) have a new line for use in laptops:

http://www.sandisk.com/OEM/ProductCatalog(1321)-SanDisk_SSD_SATA_5000_25.aspx

Seemingly difficult to find though.
