Why are they targetting 750MB? Once you've decided to go above the capacity of a CD why restrict yourself to just a little more, rather than say 1GB (for small USB drives) or 4GB (for single layer DVDs).
- Symmetry 15y agoTo minimize download times, though I do sort of think that 1GB might be better.
- robin_reala 15y agoHow much available space is there on a 1Gb flash drive when formatted using FAT32?
- omh 15y agoWell less than 1024MB, but still a lot more than 750MB
- dspillett 15y agoA bit over 950MiB if you are talking about pure space. Assuming a cluster size of 512 bytes (IIRC FAT32 doesn't need bigger blocks than this until the 2TiB mark) you are going to waste an average of 256 bytes per file (but lets be paranoid a consider the worst case: losing 511 bytes per file. The 10.04 CD contains 1300 files, if we suggest 12.04 is going to double that then you could lose you are only going to drop another Mib or two this way. So 750 does seem to be an odd figure to aim for. They are not even thinking about people overburning on CDs, IIRC 735MiB is further than you can usually push that. Is there any common storage size that divides nearly neatly into 750MiB chunks?
- batista 15y agoMaybe they are thinking it from the standpoint of what they need to add, rather than how much they have to FILL.
- jcastro 15y agoThis is pretty much the outcome of the session at UDS. I don't recall what the final agreement was but the idea is to ratchet things up as developers need it without just tossing everything onto the disc at once.
- lloeki 15y agoOn a 1GB stick that leaves 300MB room for persistence, if Ubuntu ever supports that.
- keithpeter 15y agoUbuntu's live disc creator does support persistent storage. You can have an iso image and then add some of the spare space for the storage. I use this with a 4Gb usb stick myself. You can also install ubuntu to a stick with 8Gb+ of storage of course.
