Hi. it seems one can never ask enough questions I finally bought my laptop (about 3 weeks ago) and have been experimenting with Cubase. now it's time for me to buy my pre-amp and the external, however 7200RPM external's seem to only start at 500GB here in South Africa (far too much space for me + a hefty price tag to go with it). I am looking more in the range of 80GB, however these harddrives (all SATA) seem to only be available in 4200RPM or 5200RPM models. If I go with the 5200RPM model I could save around R500 or more (say $90), although i do not know the cache memory settings on each or how this will affect the writing process... My question is, is it with the additional $90? Is a 5200RPM HDD good enough for home recording?
