Temperatures have always played a critical role on storage drives and in recent years we’ve seen it cause drives to fail prematurely and we’ve even seen some SSD performance results change for the worse if components were too hot or too cold. Since temperature is an important thing to keep an eye on we check the idle and load temperatures on all of the drives that we review. To get the idle temperature results we leave the drive sitting on an open air test bench in a room that is 19C. For the load numbers we use IOMeter to write 128KB to the drive sequentially for 20 minutes and record the top temperature.
All three capacities of the ADATA SP550 series that we tested had idle temperatures of 26-28C. At full load where we wrote constantly to the 120GB model we found the temperature topped out at 57C. ton
The load temps on the 240GB and 480GB drives is higher due to additional TLC NAND chips being inside the enclosure and both of those drives topped out at 61C! This is pretty hot for an SSD, but still below the max temp of 70C.
Let’s wrap this up!
