Samsung has continued to refine their product line, and the SM843Tn is already supplanting the SM843T we tested today. The SM843Tn is a newer model with a die revision, and similar performance and endurance specifications. Samsung OEM SSDs can be hard to find in the wild, but some distributors, such as RamCity, have access to Samsung OEM drives.
The most redeeming quality of the SM843T was its consistent performance during our tests. The SM843T does not sport the flashy performance specs of other SSDs, but its consistent performance is clearly a strong suit. The benefits of consistent performance are huge in the datacenter. Faster performance often comes at the price of performance consistency. Steady performance is more desirable; especially in RAID and mirrored environments.
The SM843T scored low in the 100% 4k random read category, but narrowed the gap during our 8K tests. The strength with 8k workloads is important, as the majority of applications in the datacenter lean heavily upon 8k performance. In 8k random read testing, the SM843T placed a close second to its counterpart, the SM843. In many cases, the two Samsung SSDs were very close in performance, but the terrific random read speed of the SM843 is hard to beat in many tests.
The solid performance of the SM843T with 8k workloads carried over to the server workloads. The SM843T placed second in the OLTP workload, but did so with a very tight performance envelope, with very little variability. The write-intensive email workload also did little to faze the SM843T. The SM843T placed second in the workload with a consistent performance profile.
Sequential performance was a strong suit, with high marks in sequential read and write workloads. The SM843T excelled during mixed sequential testing by leading nearly every write mixture test. Power consumption for the SM843T was miserly, and its overall efficiency results were competitive with the other leading SSDs in the test pool.
The SM843T offers power-loss protection with Tantalum capacitors and SPOR (Sudden Power Off and Recovery) technology. This combination of hardware and firmware guarantees protection of data in the event of power-loss. The SSD also features a two-million hour MTBF, and a one per 10E17 UBER rating.
Samsung also provides specific overprovisioning guidelines to help users boost random write performance and increase endurance. We would like to see other SSD manufacturers follow suit with similar information. With the competitive nature of the SSD market, users can find great deals and tailor their purchase to their specific workload requirements.
The SM843T is covered by a five-year warranty, and is already in service in datacenters around the world. Samsung's fast pace of innovation promises more exciting new SSD technologies, and we will be following up with further products evaluations soon.
