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.
A number of years ago, the storage industry got together and developed a solution between the OS and the SSD by creating a new SATA command called TRIM. It is not a command that forces the SSD to immediately erase data like some people believe.
The battle between the OCZ Vector and the Samsung SSD 840 Pro has been closely contested ever since the Indilinx-based drive arrived late last year, though when push comes to shove OCZ could be on the losing end.
Meet the Vertex 450, OCZ's latest addition to the Vertex SSD series based on a slightly modified version of the Barefoot 3 controller that is designed to be more cost effective. So how does the new Vertex drive fare against the best SSDs in the market including OCZ's own?
