Originally posted by wizofoz I'm old enough to have worked with 64k of RAM and 5 1/4inch floppy discs. I could never have imagined even a megabyte of storage. 1TB cards will be stock standard storage units in the near future. What is the unit name for 100 TB? 1000TB? They will be next.
I don't think it will be all that near future. Right now, only 64Gb SDXC cards are available. A 1TB card is 16 times as large. We'll probably see 128GB cards within a year or two.
I think that the immediate users of 64G cards will be those that do a lot of video with their cameras. A 30 minute video is, what, about 2-3GB? That means about 32 hours of video on a 64GB card. For an avid video shooter, 16 hours on current 32G cards may not be enough for a long vacation.
I suppose that 645D users may want/need 64GB or more. I haven't heard, but I'm guessing that the RAW files for that beast are around 40MB.
A hundred TB is just a hundred TB, just as 100 GB is just 100 GB. A thousand TB would be one Peta-byte.
