If our review of the Intel SSD 520 shows anything, it's that engineering is a key component when it comes to SSD performance. Specifically, when thinking about the effort that went into development of the firmware on the SSD 520, we see the effort pays off.
Exceptionally strong performance up against OCZ Vertex 3 Max IOPS; Incredibly fast compressible speeds in our mixed-workload tests; Industry-leading reliability testing; Custom firmware and engineering shows its value
More expensive than other SandForce SF-2200-powered SSDs with synchronous NAND
