Crucial P310 1TB PCIe Gen4 NVMe 2280 M.2 SSD Review

Storage/SSD by stefan @ 2024-10-05

The P310 1TB drive from Crucial does perform near top TLC offerings, surprising for a QLC drive but presents itself with the usual shortcomings when talking about TBW versus TLC, while the lowest write speed directly to QLC is considerably lower, around some high-performance platter drives.

Crucial P310 was clearly thought as a mainstream product, with no DRAM caching, while the temperatures remain excellent during intensive loads, allowing it to be used in systems with less-than-ideal cooling systems for the M.2 drive such as the PS5.

Drive Behavior during Continuous Write

Before jumping to the second stage of our testing, our aim was to fill the drive over 50% and monitor its performance along the way, including the controller temperature. In IDLE mode, the controller is quite cool, at about 41 degrees Celsius:

The write workload started at optimal speed:

We noted a small performance drop to about 3GB/s after writing about 145GB:

The controller was only recording about 50 degrees Celsius at this time, so we can rule out throttling:

A sharp drop occurred after writing about 195GB of data:

While the Windows Explorer speed recording was all over the place, we have got a clear look in Task Manager, the drive writing continuously to QLC with speed ranging from 185MB/s to 202MB/s:

The drive remained cool even when the pSLC cache has been fully filled and did not increase in temperature till the end of our test workload:
