AFAIK the PS3 doesn't have a swap file on the HDD, so you wouldn't have a large number of writes. You'd of course have games saves and the like, but those are small. The PS4 with the constant video recording enabled would put a lot more write strain on an SSD, and people have used the same SSD in those for years.yeah i thought about an ssd got 1tb just laying around and an ssdhd with 2 tb another 4tb is on the way so i got plenty of options but with ssd you have only x cycles till an ssd is dead so i personally tend to use hdd over sdd in consoles
Most SSDs have write capacities of several hundred times their size. The drives in my PC with Nvidia Shadow Play on have been in use for almost three years and say they are at 2% of their lifetime writes which puts the total around 800TB for total lifetime writes.
