OCZ Launches Agility 4 Series: Indilinx Everest 2 on a Budgetby Kristian Vättö on May 30, 2012 12:25 PM EST
OCZ has now released their Agility 4 SSD series. Just like the move to Vertex 4 (our review) from Vertex 3, the Agility 4 uses OCZ's own Indilinx Everest 2 controller (the actual silicon is from Marvell) instead of SandForce. The differences between the Agility and Vertex series has not changed with the fourth generation: Vertex uses synchronous NAND whereas Agility uses asynchronous NAND. The Agility 4 uses a SATA 6Gb/s interface and comes in a 2.5" 9.5mm form factor. Below are the full specifications:
|OCZ Agility 4 Specifications|
|NAND||2Xnm asynchronous MLC NAND|
|Number of NAND Packages||8||16||16||16|
|Number of Die per Package||1||1||2||4|
|4K Random Read||46K IOPS||58K IOPS||48K IOPS||48K IOPS|
|4K Random Write||47K IOPS||72K IOPS||85K IOPS||85K IOPS|
Read speeds seem to be the most affected by the use of asynchronous NAND. Vertex 4 offers sequential reads up to 550MB/s and 4K random reads of 90K IOPS for 128GB and up, whereas Agility 4 maxes out at 400MB/s and 58K IOPS. Write speeds have not taken as big a hit, although Vertex 4 is still noticeably faster by offering up to 475MB/s sequential writes. However, it should be kept in mind that these are figures provided by OCZ—we'll find out the real world performance when we get our review sample(s). At least in my eyes the figures for Agility 4 sound fairly conservative and rounded, as usually we see manufacturers listing differences of 5MB/s or even less, while for now all sequential numbers are even hundreds.
NewEgg does not sell the Agility 4 yet but I was able to find all models except for the 64GB from Amazon. The pricing of Agility 4 is indeed competitive. The 128GB Agility 4 is actually slightly more expensive because 128GB Vertex 4 currently sells for $140 in Amazon, but pricing may change as more stock comes in. Bigger capacities, on the other hand, offer nice savings over Vertex 4. The 256GB model is $40 cheaper and the 512GB model is $79 cheaper than the equivalent Vertex 4 models. Amazon currently has 128GB and 256GB models in stock in case you want to be an early adopter. The 512GB model is out of stock and the 64GB model is not even listed, so we're still waiting for availability.
We're already working on getting review samples from OCZ, so stay tuned for our review!
