Final Thoughts




Density in a datacenter environment is supremely important. Other than performance, it could be considered the most important factor when considering a flash array. Samsung realizes this and has responded with V-NAND datacenter solutions that offer at least double the capacity of competing solutions in the same footprint. V-NAND is superior on all fronts, providing greater capacity, more endurance, and lower power consumption, which translates to lower TCO and a smaller footprint in the datacenter.



Looking at the performance we were able to achieve with our configuration, we had no problem meeting or exceeding Samsung's listed specifications for both the SM863 and PM863. The SM863 dominated our testing with its exquisite consistency and overall performance. We believe the SM863 is without a doubt the best SATA-based, mid-endurance, mixed workload focused SSD available on the market today.


We believe the PM863 is destined to replace the already potent 845DC EVO. The PM863 improves on the planar-based 845DC EVO across the board most of which stems from its second generation V-NAND flash array providing lower cost, better performance, more endurance, and higher density. The PM863 demonstrates that TLC is a viable, high-performance storage medium that is well suited for read-intensive applications.


Simply put, the SM863 and the PM863 are in a class of their own, and there is nothing on the market today that can provide a greater value in their respective market segments.
