Mainstream Indilinx

Mainstream Indilinx

Earlier this year in July, we reviewed OCZ’s new high-end Vertex 4 drive. The new Vertex 4 drives are significantly different from its predecessors because OCZ made the jump from the very popular SandForce SF-2281 controller to the new Marvell 88SS9187 controller and rebranded it as their own Indilinx Everest 2 controller.

Traditionally, the Agility series has been OCZ’s SSDs for more budget-conscious users and this hasn’t changed. To differentiate the Agility 4 drives from the more upmarket Vertex 4 ones, OCZ has fitted the Agility 4 drives with cheaper and slower asynchronous NAND. The Vertex 4 has synchronous NAND and the difference is that synchronous NAND transmit data on both the rise and fall of the signal wave, which translates to higher raw data throughput and faster response times. That aside, the Agility 4 has a smaller amount of onboard DRAM cache. To be specific, it has 512MB of onboard DRAM for prefetching read requests - that’s half of what the Vertex 4 has.

Whether or not the aforementioned tweaks will greatly hamper performance, we shall see later, but for now, here’s a quick look at the OCZ Agility 4 drive.
