ADATA was one of the two companies to release consumer SSDs with Realtek's first-generation flash controller. The controller was an entry-level model, so I'm not surprised you haven't heard of it or knew that Realtek jumped in the SSD game. The company has two follow up controllers and has high hopes that you will notice.
The ADATA XPG SX6000 Pro uses Realtek's RTS5763DK mainstream NVMe controller. This is a mainstream DRAMless design that features host memory bus (HMB) technology to improve performance over true DRAMless SSDs.
The purpose of these mainstream SSDs is to deliver value to shoppers. The SX6000 Pro starts at just $38 at the time of writing, and 1TB model sells for just over $100.
The XPG SX6000 Pro ships in four capacities that range from 1TB to 256GB. Unlike the original SX6000 that only used two PCIe 3.0 lanes, the Pro models use all four lanes flowing through M.2 connectors.
The performance for the 1TB and 512GB models show identical performance with 2,100 MB/s sequential reads and 1,500 MB/s sequential writes. The random performance for these drives tops 250,000 IOPS read and 240,000 IOPS write.
The 256GB SX6000 Pro reaches 1,800 MB/s sequential read and 1,200 MB/s sequential writes. It sports random performance of 190,000 IOPS read and 180,000 IOPS write.
All three capacities use Host Memory Buffer (HMB) technology. This helps to reduce the cost of the drives by not using an onboard DRAM cache. Instead of local DRAM, the drives use a small portion of your computers system memory to cache the table map of the flash. Technically, we still call these DRAMless SSDs, but the performance is significantly higher than the planar flash DRAMless models that came to market using the SATA bus three years ago.
Pricing, Warranty, and Endurance
The ADATA XPG SX6000 Pro is a very low-cost NVMe SSD with prices very similar to SATA models in the same capacities. The 1TB model currently sells for $107.99 at Amazon. Amazon also carries the 512GB model for $57.99 as well as the 256GB model for $37.99.
ADATA back the series with a full 5-year warranty and strong endurance ratings for mainstream / low-cost NVMe drives. The 1TB bring with it a 600 TBW rating. The endurance cuts in half with each capacity. The 512BG model rates at 300 TBW and the 256GB rates at 150 TBW.
A Closer Look
The packaging is similar to other consumer SSDs from ADATA. The company gives users a thin heat sink/shield with this model that users can attach with the included double-sided thermal tape.
