(or so I've read) I think the problem is the number of erases actually (but you erase in order to write, so)... This is number really is more or less, some companies achieve higher number of writes, i think this figure shows a worst-case scenario. Also, it's actually 10k writes per sector... git, as far as i understand, will append new versions to the repository, so it's writing on other sectors and only once. Only if you remove, prune, cleanup the repository, then it would erase... and if you were to format it every day and write to it once a day, (say one new write per sector, on every sector, once per day)... i've quickly calculated the key will last around 27 years. I'll be glad to buy a petabyte usbkey for 10$US in 27 years man! lol Simon
