According to Intel, the utilizable cache size on the SSD for SRT is between 18.6 GB and 64 GB.

If I buy a "64 GB" SSD I only get 60 GB of usable space, thus underutilizing the SRT technology a bit and putting the SSD to maximum stress.

So the question is, does it make sense to buy a "128 GB" SSD (120 GB usable) for a 50% higher price compared to a "64 GB" SSD to use for SRT?

This way the full 64 GB will be used for cache and there will be some room left for wear leveling for SSD to perform a little more reliable and fast.

Is that so?

Will the wear leveling actually use the whole 120 GB of SSD space in 64 GB SRT mode?
