Of the data center SATA SSDs we've tested, the Samsung 883 DCT delivers the highest performance thus far. The series will appear in a number of future reviews where we use the drives in application NAS systems for read and write cache. The low price and wide availability opens this series to a number of users, not just the targeted data center racks.
The Samsung 883 DCT series bridges the gap between the 860 DCT and the 983 DCT NVMe series. The 883 DCT includes features not found on the 860 DCT, like host power-loss protection, higher QoS, and more endurance. The series also features Class 0 AES 256 encryption and end-to-end data protection. These are also features found on the 983 DCT NVMe series.
In our testing, we observed higher performance with the 883 DCT compared to the older Samsung PM863a and Seagate Nytro 1351, all in 3.84TB capacity. At high queue depths, the older Samsung PM863a delivered equal performance in our synthetic workloads. At lower queue depths and in our applications tests, the 883 DCT walked away from the PM863a when comparing equal capacities. The 883 DCT also smashed the peak performance of the Seagate Nytro 1351. The Seagate often delivered better performance consistency, but at the cost of peak performance under heavy workloads.
The Bottom Line
The Samsung 883 DCT series provides the highest performance possible to date over a SATA interface. The series includes features not found on entry-level data center SSDs but doesn't break the budget.
