These may well be what is being used in the Red Ram.
Found on Hardmac (http://www.hardmac.com/news/2007-06-18/#6901):
"The website Trustedreviews published the first test of a 32GN Samsung SSD, while comparing performance with a 250GB 2.5" HD and a 1TB 3.5" HD from Hitachi.
In summary, a SSD boots faster than a 2.5" HD thanks to its low access time, but can not compete with a 3.5" HD. In all other tests, the SSD can not compete with both plate-based HD models due to its low effective writing and reading speed.
This is only the beginning of the era of flash memory-based solid state drive, and in the coming months/years, improvements should speed up performance to better compete with plate-based HDs."
With the link to Trustedreviews :
Hardmac doesn't mention one of the main advantages of SSDs, its resistance to shock and vibration, Trustedreviews gives comparative numbers on page 2 of heir review. This is why they are particularly interesting for onboard camera recording, however SSDs are, or at least this one is, a rather poor performer for sustained data read and write.
