I am thinking about buying an SSD to replace my HDD. Am I right in thinking that a larger SSD will last much longer than one with less space? Let's say you have a 64 GB SSD with Trim with an average of 10.000 writes. So in theory, this drive will last 64 GB * 10.000 writes = 640.000 GB = 640 TB of total data? With this calculation, a 128 GB drive should last twice as long (1280 TB)?
