single layer ssd's vs. dual layer ssd's ?
where did you get that information from ? that quote was talking about 1994 vs. 1997 ssd drives.
SSD Myths and Legends - "write endurance" article in StorageSearch.com
if you don't think writes need to be minimized to ssd's, you're taking an unnecessary risk imho.
remember when cells die, the data on it is gone... it cannot be accessed or retrieved the way you might be able to on a non-clicking platter drive.
even if 100,000 write cycles is true (even that is low imho) ... temp files,page files(even if it's turned off due to having 8+Gb's of memory) ,cache and temp internet files(cooklies), email, system restore etc etc files can add up to 500-1000 writes per day.
A lot of companies claim 20+ Gb of writes per day, but like i said, once the electron based cell dies, the data is irretrievable.
