Hi All !I want to instal SAP 4.7 in my laptop; This requires around 50 GB space.But my laptop has a configuration of 60 GB (net 51 GB), 512 MB RAM and 1.86 GHz processor. I feel it will require external HDD.I want to know that if I go for external HDD how will be the performance of the laptop vis-a-vis SAP module; how will external HDD affect the speed, performance etc. of the SAP module during its use.If I use internal HDD then what?Please help me out of this with the advantages and disadvantages in both the cases.What will be the best brand and price for each of them.RegardsJS
