The ADATA Ultimate SU800 SSD Review (128GB, 256GB, 512GB)

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.

The ADATA SU800 shows a huge drop in performance when the Heavy test is run starting with a full drive, but when starting with an empty drive the 512GB SU800 performs quite well for a budget SSD and the smaller capacities are only moderately behind their competition.

The average service time metric highlights the discrepancy between full drive and empty drive performance. The SU800s and the similar Silicon Motion engineering sample show the largest difference by far, followed by the Crucial MX300 and the Samsung 750 EVO.

Very few budget SSDs can keep latency below 10ms through almost all of the Heavy test, but the 512GB SU800 manages it when the test is run starting on an empty drive. When operating on a full drive or when considering the smaller capacities, high latency is far more common.

The power consumption of the 512GB SU800 trails slightly behind the Crucial MX300, but is still good for a budget TLC drive. The smaller capacities rank last due to taking longer to complete the test, and the energy usage is substantially higher when the test is run on a full drive.
