The 4 series OCZs are fine, I wouldn't worry about them. I would, as noted above, consider a 256 Gb drive though, especially if you want to use this in the future as a single drive. 128s fill up quickly these days.
i am fine in that sense, i will have a 1tb second drive for storing data and downloads etc
and all my important stuff ia backed up to external drives on a regular basis
i have a 160gb drive in just now and 123gb is free space lol
