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

AnandTech Storage Bench - Heavy

Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here. This test is run twice, once on a freshly erased drive and once after filling the drive with sequential writes.

The ADATA SX6000 Pro has decent overall performance on the Heavy test for an entry-level NVMe SSD, and its full-drive performance is the best for this market segment. The Mushkin Helix-L and Intel 660p both use Silicon Motion controllers that offer better peak performance for the empty-drive test runs at the expense of worse full-drive performance (even the high-end SMI-based drives are a bit slower when full than the SX6000 Pro).

The average and 99th percentile latency scores for the SX6000 Pro are fine: all significantly faster than a mainstream SATA drive, with no huge latency spikes from running the test on a full drive.

The average latencies from the SX6000 Pro are higher than most NVMe SSDs but still better than SATA. For writes, the SX6000 Pro gets close to some high-end NVMe drives.

The 99th percentile read latency is the first sign that the SX6000 Pro has some difficulty with handling the Heavy test on a full drive, but the read QoS in that case is still better than the SATA drives. The 99th percentile write latencies are good whether the test is run on a full or empty drive.

The efficiency scores for the SX6000 Pro are in line with most high-end NVMe SSDs, but the other DRAMless NVMe drives again use half the energy to provide similar performance.
