I am considering another harddisk. While having a seagate barracuda V
120gb now I think I will change from seagate to samsung (their new
Spinpoint series seems very silent and cool as well as cheap, and the
new seagates don't seem quiter than the samsungs anymore). So some
questions arises, mainly concerning speed.
First there is 5400 and 7200 versions of the samsungs out there. I guess
5400 rpm drives qill be cooler and quiter - but what about performance.
Will I for instance be able to record two simultaneous programs with two
cards delivering mpeg2 streams with the 5400rpm version? Anything else
to think of when it comes to drive speed?
Second theres the cache size. How much do the cache size matter when it
comes to use it as video HD?
I've the Samsung SpinPoint 1614N, it has 8MB Cache and 7200rpms. It's
very silent, and transfers about 60MBs/sec. It's obviously too fast for
vdr ;-). A "normal" vdr-stream is around 500-600 KB/sec, so any hdd
should be sufficient.
