The price-conscious SATA segment is incredibly competitive, especially in the OEM space. SanDisk is qualified with five of the largest server vendors, and four of the largest storage vendors. The CloudSpeed Eco leverages a custom Marvell controller with firmware utilizing the Guardian Technology Platform, and is optimized to deliver high capacity and consistent QoS at a very competitive price point.
Top performance is not always the most important factor with the read-centric class of SSDs. Many SSDs can deliver enough performance to satisfy the majority of read-centric workloads. Addressable capacity, which affects the dollar-per-GB of the competing SSDs, comes to the forefront. More addressable capacity directly equates to better TCO. The CloudSpeed Eco exposes a high percentage of its flash as user-addressable capacity. This has an impact on performance, but allows SanDisk to provide very aggressive pricing. The M500DC has very impressive performance metrics, but falls in a higher price-per-GB bracket due to less user-addressable capacity.
SanDisk also offers robust data protection features embedded into their Guardian Technology Platform that provides key features, such as power-loss protection and end-to-end data path protection. The other competitors in this class also feature power-loss protection, which makes this segment particularly competitive on a price basis.
The CloudSpeed Eco's strong suit is solid random read performance in 4k and 8k workloads. The Eco scored lower marks in pure random write workloads, but often exhibited a tighter performance envelope than the competition. The Eco also scored well in our mixed testing with high averages under heavier write workloads, but experienced some variability during the test. The Eco placed second in sequential read and write workloads, providing performance that will address media streaming and VOD workloads well. The mixed sequential testing was encouraging; the Eco took second place in the majority of the test.
The CloudSpeed Eco did not perform as well in our server workloads as other competitors. The CloudSpeed Eco architecture focuses on a consistent QoS in favor of higher peak performance that can result in performance inconsistency. Inconsistent SSDs can hamper RAID performance due to the speed of the RAID array falling to the level of the slowest I/O. Multiple SSDs generating these outlying I/O's in an array compromise overall speed, and the tried-and-true method of boosting performance by adding more SSDs simply multiplies the problem. The Eco displayed a consistent performance profile in many of our tests that will be well suited for RAID arrays.
The CloudSpeed Eco features a lower three-year warranty period than the other SSDs in the test pool, but this is common in the OEM market. SanDisk proprietary Guardian Technology Suite and trusted components deliver an extremely price-competitive SSD geared for read-centric workloads. The Eco's high addressable capacity and low price earns it the TweakTown Best Value Award.
