Maximum Surface Temperature

We monitored the surface temperature of six solid state drives, together with a low-powered hard disk drive for comparison, during their benchmark runs. The following chart shows their operating temperature range, from idle to maximum load. Please note that instead of giving you the absolute numbers, we are showing the temperature delta, which is the difference between the actual temperature and the ambient room temperature.

The Corsair F90 solid state drive was the coolest drive in this comparison, edging out the Kingston SSDNow V+ (Gen 2) solid state drive. The Kingston SSDNow V+ (Gen 2) was cooler at idle but the Corsair F90 was much cooler at full load. In fact, the Corsair F90's full load temperature of just 2.4°C above ambient temperature matches the idle temperature recorded for the OCZ Vertex 2 (E) solid state drive!

Of course, this excellent performance is partly due to the lower number of NAND flash chips used in this 90 GB model. You can expect higher power consumption in Corsair Force series models with larger storage capacities.

Transfer Rate Profile

Unlike hard disk drives, solid state drives do not have different areal densities. Hence, a virtually flat transfer rate profile across the entire capacity, punctuated by regular dips, thanks to garbage collection performed by the drive. The Corsair F90 SSD delivered a read throughput of around 282 MB/s, which is just a tad below the maximum read speed of 285 MB/s.
