The generations so far has been roughly once every 2.5 years.  Stretch it out to three years.  Nor has each generation provided a doubling.  Let&#x27;s suggest a factor of 1 and two-thirds, to be on the safe side.<p>We could then expect LTO-10 in 2023, LTO-11 in 2026, LTO-12 in 2029, LTO-13 in 2032, and LTO-14 in 2035, with a final uncompressed capacity of about 234 TB.  Note that I have been conservative for both the generations and the increases in capacity.  If you squeezed in an extra generation and assumed a full doubling each time, you would end up at 1,152 TB, or the 1 PB predicted by the article.<p>This looks to be ... right on schedule.<p>Now if the cost of the drives would only come down ...
