[mythtv-users] SSD's

[David Scammell]

Hi,

More of a thinking out loud comment than anything else but the price
of SSD disks are dropping, a 60GB disk can be bought in the UK for
~£100, having had a pair (of bigger) disks to play with at work I was
impressed with their:

speed: 80MB/s (from memory)
power/heat consumption: 1w (a guess) but very low, they get barely warm.
size: 2.5in
performance: no seek time at all.

I was thinking about, when the price comes down a teeny bit more for
one for fronting the the MBE storage. I;m thinking that this disk
would be chosen for new recordings ahead of any other storage grouped
disks provided it was most empty, which can be done in off periods,
after an evening recordings have finished by moving the recordings to
the other disks. The point is that during busy periods, recordings or
comm flagging the io to the disk would cope much better than
conventional disks as there is no delay due to seek time. Running a
fileserver benchmark at work showed a stunning throughput compared to
normal disk, down to no seek time. Having multiple recordings going to
disk at the same time (say multirec) shouldn't bandwidth limited, also
the machine OS/mysql could live on the same disk. Obviously those big
raid volumes that some users have could be spun down more frequently.

Thoughts?
