I just meant it's easy if one wants to. It does not have to be OCZ and it does not have to be business or power user or whatever.
1PB is of course a highly unrealistic number and I said that more as a joke. However, 20GB or 50GB a day is not meant as realistic either. It's just put there for the manufacturers (hopefully) to reduce the number of returns.
By the way, I think you haven't reached 3TB with that Vector because you use it mostly as a booting disk only, not for video editing or torrenting and because you have kept virtually unlimited number of devices. At 10MB/s download and 10MB/s upload, it's 8.64TB write a day at least. That's not what an "average" PC user does, not in statistics, but it's not uncommon to see those that do write that much among SSD users. There's a vast gap between 8.64TB and 1PB, but 50GB is still less than 1% of 8.64TB.
20GB a day times 730 days is 14.6TB. 29.2TB in four years, still less than 100TB for 50GB a day, I don't think they are realistic numbers when SSD based on NAND is meant as STORAGE (something between RAM and backup media like tapes and optical disks.)
