We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.
Random Reads
Crucial's P310 2280 displays smooth acceleration as it moves from QD1 to QD8 in each of the four threads used for testing. With a single thread, the performance ranges from 19,700 IOPS (80.69MB/s) at QD1 up to 122,790 IOPS (502.94MB/s) at QD8. Using four threads the performance ranges from 76,982 IOPS (315.31MB/s) at QD1 up to 351,123 IOPS (1,438MB/s) at QD8.
Random Writes
Switching over to random writes, in all four threads the performance rose quickly from QD1 to QD2 with the fastest rise seen in the three and four threaded tests. After QD2 all four threads see the performance begin to plateau out.
