The ADATA XPG SX6000 Pro 1TB SSD Review: Realtek's Entry-level NVMe Solution

AnandTech Storage Bench - Light

Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here. As with the ATSB Heavy test, this test is run with the drive both freshly erased and empty, and after filling the drive with sequential writes.

The ADATA XPG SX6000 Pro has the worst overall performance on the Light test out of all the NVMe drives in this batch, though several drives with better peak performance are slower when the test is run on a full drive.

The average and 99th percentile latency scores for the SX6000 Pro are high for a NVMe drive, but it doesn't lose much performance when the test is run on a full drive so those worst-case scores are still better than the SATA drives. Most of the other low-end NVMe SSDs can degrade to SATA or worse performance.

The average read latency of the SX6000 Pro is strongly affected by the drive being full, while the average write latency is completely unaffected. None of the other low-end NVMe drives keep write latency so low when the test is run on a full drive.

The 99th percentile read and write scores for the SX6000 Pro are all good, but the solid write QoS even for a full drive is impressive.

The energy usage of the SX6000 Pro over the course of the Light test is again roughly twice that of the other DRAMless NVMe SSDs, but it's not particularly high when compared to NVMe SSDs in general.
