A sun engineer has told me about a feature called goldcap, it is mainly=20
a highest capacity capacitor that allows the disk to use internal dram=20
caching without the risk of data loss (the capacitor delivers enough=20
charge to write the dirty blocks to the ssd in case of immediate power=20
loss). Maybe there is something similar for 2,5" ssd for laptops.
Those ssd will also have no wearing out.
