FORGET using larger clusters on SSD even if they did (not saying they do) boost performance by a SMALL amount.
You are limited to 80 gigs. If you doubled the cluster size, you would also double the "LOSTED" space. Remember a 100 byte file requires a full cluster be it 4 K, 8K, or 16K. The old rule of thumb was to multiply the number of files times 1/2 cluster size - this is whate you lose. If you have 30,000 files on C drive times 4 K cluster/2 = 60 Megs of lost space. If you upped the cluster size to 16 K then the lose would be 8K x 30K or about 240 Megs.
PS my C drive has 120K files with a 16K cluster size I would expect a lose of approx 960 Megs, or 1 Gig and for a small performance gain - not worth it
For storage drive with large Video files, Yes it is a viable option.
