I'll be using Samsung 1TB 840 EVO SSD's as primary drives and want to make a good choice for a secondary drives on a couple of HP ENVY's. It looks like conventional HDD's offer much better capacity with reasonable speed for the secondary drive position. The HP ENVY's, have been known to have heat retention issues so I be using my Targus triple fan bases (disappointing performance but helpful). The big heat producing devices appear to be the screen and my case I7 quad core processors. The screens of course easily dissipate residual heat and stay cool. The quad core processors are the main problem and are downstream from the drives. A single fan is positioned to be most effective to remove heat from the the microprocessor. The SSD's use little current & probably generate very little heat but the new secondary drives need to be at least 7,200 RPM in a 2.5" HDD with a large capacity (1TB bare Min to 3 TB or more if available) providing the price is reasonable.
Recommendations for a secondary drive greatly appreciated!
