Same goes for RPM. A larger cache is probably better, though.
It would seem to make sense to format with the NTFS cluster size at 64K, since we're talking about pretty big files. I haven't been able to tell if it really helps, though.
How full the drive is shouldn't matter - although for an SSD, it apparently does. On a spinning-platter drive, if you frequently delete files then record more, the drive can get fragmented and that can slow things down, especially if it's really full (over 80%). If that happens I suppose you could hook it to a PC and run a defrag program on it.
For an SSD, fragmentation doesn't matter, it is not recommended running defrag programs on them, it won't make any performance difference and 'wears' it out with all the writing. Sort of like teaching a pig to whistle, it won't work and only annoys the pig ;-). JH, I know you referenced only hard drives, just thought I'd add some elaboration (so folks don't go out and 'defrag' their SSDs).
As SSDs get used and filled up, even if files are removed, they can slow down, one solution is to plug it into a PC and if the OS is anywhere near recent, do an 'optimize' on it which does something called a 'trim' operation. VERY fast and cleans things up. Later Windows won't even let you defrag an SSD although 3rd party programs might.
Still, I would think with the speeds of SSD, it wouldn't be very relevant to the iView over a USB connection.
I've been using an old donated external 500 Mb HD, don't really know its specs, but no indication of a performance issue (well, until I filled it up and had to force-watch several programs ;-)).
Tell ya one thing though, I sure wish the iView had an offline operation that would convert those video files to MP4s, they are SO much smaller. Not fast enough to do it live, that takes a healthy CPU. One could do that on a PC though since iView does understand MP4s, I've played them back with no problem. But that's a fair bit of work unless you could write some script to handle the details or had a good converter program that would.
