Teamgroup T-Force Cardea A440 Pro Special Series 1TB SSD Review

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.

At QD1 the T-Force Cardea A440 Pro Special Series produced a single thread random read result of 20,336 IOPS (83.298MB/s). Using two threads saw the performance rise to 41,311 IOPS (169.21MB/s), three threads produced 59,524 IOPS (243.98MB/s) and with four threads 78,328 IOPS (320.83MB/s). The drive’s performance increases smoothly as the queue depth deepens for each thread count.

When it came to 4K random write performance using a single thread, the performance slowly increases from QD1 (61,900 IOPS) to QD2 (78,076 IOPS) before beginning to plateau out ending the test run at 78,738 IOPS (QD32). Using two and four threads the drive accelerates sharply from QD2 to QD4 before levelling off. Using three threads sees the performance climb pretty steadily without levelling off.
