SSD technology grew stale after saturating the SATA 6Gb/s bus, bringing minor improvements and making up for it with price cuts. With new PCIe and M.2 drives presenting a high performance alternative, it's time for a roundup. We review fourteen of the best consumer-grade SSDs using the SATA, PCI Express or M.2 interfaces and tell you what to buy.
Released in early June, SanDisk's Extreme Pro is the successor to the venerable Extreme II, which was among the best SSDs of its generation in terms of performance and reliability. The drive is aimed at gamers, enthusiasts and professionals who demand the highest real-world performance, and will trade blows with Samsung's excellent SSD 850 Pro.
The new SanDisk Extreme II features an in-house developed firmware which helps to set it apart from other SSDs using the same controller. Also of note, the second generation Extreme series has dumped the SandForce controller in favor of the new Marvell 88SS9187, the same controller used by the Crucial M500.
SanDisk is pricing the 240GB Extreme II competitively fetching around $230, right on target with the Vertex 450 and also in the neighborhood of the Samsung 840 Pro, which will remain a secondary focus throughout this review.
