Is this a good idea?
I have a FAT PS3, 40 GB, I had YLOD once, half years ago, and it was professionally repaired, since then there wasn't any problems... but the warm weather is coming soon, and I don't want to have a YLOD again.
With an SSD drive there would be lower power consumption (1W with SSD, ~15W with HDD?), so it would be easier on the power supply, also, the HDD generates heat, I imagine it is around 40-50 °C, if I remove its case after I turning off the PS3 I can feel that the HDD is relatively hot, and an SSD wouldn't generate any heat... so the temperature of the console could be cooler overall, also it could save a little lower power consumption.
Do you think that this is worth it? Would it help to prevent YLOD, and preventing the overheating of the console? (it isn't in an enclosed place, the venting is good, but I'm using it for long hours when I can, though I can't feel that the console would be hot, even after playing 7-8 hours, it isn't that warm, but as one time YLOD already happened it would be better to prevent it if possible...)
