The Crucial T700 SSD easily overheats and slows down compared

The Crucial T700 SSD easily overheats and slows down compared to the HDD, but doesn’t shut down like the Corsair competitor

The flagship Crucial T700 SSDs, like all other PCIe 5.0 SSDs that use the advanced Phison E26 storage controllers, get very hot during operation. Especially without the use of a heat sink or active cooling. However, unlike the previously mentioned Corsair MP700 drives, they don’t turn off when they overheat. This was shown by the tests of the German edition of Computer Base.

The maximum allowable operating temperature of the Phison E26 controller is 86 degrees Celsius. What happens when the controller reaches this temperature depends on the particular SSD model. On Corsair MP700 drives, these can be disabled to prevent damage to the controller. And this process is accompanied by the “Blue Screen of Death” of the operating system.

Crucial T700 drives, on the other hand, begin to decelerate sharply when the controller’s maximum allowable temperature is reached. The drive itself does not turn off, but its performance drops to the level of disk performance, which is indicated by monitoring the CrystalDiskMark program. At this point, the speed of the SSD drops to 101 MB/s, and the latency indicators become higher than with conventional HDDs.

The Cruicial T700 and Corsair MP700 drives come with large heatsinks, which are highly recommended by the manufacturers. However, these drives are also available in versions without a heat sink. In this case, companies hope that SSD owners can provide sufficient cooling for these SSDs themselves, for example via motherboard heatsinks.

We add that solid state drives are used not only in desktop PCs but also in laptops where there is simply no room for an SSD cooling system. Some laptop OEMs specialize in large, powerful laptops that can completely replace desktops and workstations. In this case, companies can find ways to cool the SSD using the laptop’s main cooling system. But in general, the “hot temper” of PCIe 5.0 drives can severely limit their use in the mobile computing segment.
