I see you have been talking about me ^^

alfaunits: WRITE != ERASE
SSDs with a clean block pool does not erase on every write, but lets garbage collection handle the erases.

Can you give a quote or cite the source of the 32-64KB erase block on intel's SSDs?
It's possible you are refering to the largest chunks the SSD will write internally to each channel, the internal stripe size so to speak...

Anihilus, try doing a PCmark Vantage HDD run on the different stripe sizes, and maybe a timed launch-script. Anvil and Ourasi here have made launch scripts using windows apps and common programs.

Anvil here has experimented with different stripe sizes on x25-V/M RAIDs of 1-4 units from ICH10R, and I would ask him for input on the difference in real life performance.

I have been using 32KB stripe on my own 2R0 Mtron Pro 7025 since august 2008. Works as a charm for OS, and i have yet to experience any trouble. Though I have the liberty to be carefree, since they are SLC and rated for 100% duty cycle in servers for 5 years, with full warranty...
