OCZ Agility 4 256GB Solid State Drive
10 March 2013
Conclusion: TRIM Performance: While SSD's offer many benefits, there are some downsides to using flash memory. One of the biggest issues people run into is performance degradation. Over time, an SSD will run out of fresh blocks and will have to write over data the file system has marked as deleted. This procedure is very complicated and can slow an SSD's write speeds considerably. To fix this problem, most manufacturers have added TRIM support to their SSDs.
Pros: Available in 64GB, 128GB, 256GB and 512GB capacities, Good random read and write performance, Performs equally well with compressible and incompressible data, Indilinx Ndurance 2.0 technology extends life of NAND flash, SATA 6Gb/s interface, Large DRAM cache, Supports TRIM, dynamic and static wear-leveling and background garbage collection, Automatic 256-bit AES encryption, 3 year warranty, Reasonably priced
Cons: Slower sequential read and write speeds than other drives in its class, Does not include a 2.5" to 3.5" adapter bracket, Asynchronous NAND flash
Summary: The performance numbers (for the price) we saw in the new OCZ Agility 4 are one of the reasons they remain at the top of the solid state drive business. The performance is there dues to a few different advancements in technology. The first and most important would be the implementation of Marvel controller that is "Indilinx Infused". To sum up the last sentence the controller is enhanced via an OCZ made firmware.
Conclusion: As I have mentioned in my OCZ Vertex 4 256GB review, not every test in our battery of benchmarks reflects the true performance of Indilinx Everest 2 based drives. While SandForce SSDs are extremely proficient at handling compressible data and winning drag races in many tests, OCZ's own controller shines through in dealing with non-compressible information, in conjunction with the ability to pull higher I/O operations per second.
Excerpt: OCZ makes a wide range of SSD’s, targeted towards various markets. The OCZ Agility 4 is an SSD targeted at the mainstream market. OCZ’s high-end SSD’s, the Vertex line, are targeted towards the performance/enthusiasts’ market. The OCZ budget line is primarily occupied by caching SSD’s, which are designed to be paired with a hard drive to give the platter drive a speed boost.
Pros: Good overall performance, Good price-to-performance ratio, SATA III compatible, mSATA capable for onboard running, TRIM command included
Cons: No 3.5″ adapter tray included, Performance can differ considerably depending on workload
Summary: Final Thoughts
When a product gets released it is never perfect, even though it goes through many different types of tests and procedures there are always things that can be improved or simply looked over. This is why you see software or firmware updates for many products. Or even at times products are recalled. Products are often rushed out to meet demand or to jump on an opportunity in the marketplace.
Pros: Price, 3 year warranty, TRIM support
Cons: Poor performance compared to other SATA 6GB/s drives, Single request speed is very low, No drive adapter or mounting hardware included
OCZ Agility 4 256GB SSD review: the best affordable 256 GB SSD?
3 September 2012
Excerpt: The last few months has seen a steady drop in SSD prices, with one manufacturer trying to outdo the other in terms of affordability. With the older Vertex 3 OCZ released a cheaper version to stay competitive, called the Agility 3. It's done the same now, launching the Agility 4.
OCZ Agility 4 Solid State Drives: 128 GB and 256 GB Models Reviewed

Summary: Solid state drives from OCZ Vertex 4 family have been continuously praised, but their price is still far from affordable. However, OCZ also has a less expensive product in their lineup using the same design, but built with asynchronous flash memory. This is Agility 4 family. Is this one just as attractive as the Vertex 4? Let’s find out!
Summary: OCZ has positioned their Agility 4 as a mid-range solid-state drive which is built around the company's Indilinx controller. In our testing we see decent performance, that, when averaged over all our tests, can claim a solid place in our rankings. When looking at individual tests we see performance ranging from very good to poor. It seems that the Agility 4 really likes certain workloads, but doesn't do so well with other ones.
Pros: Low price per GB, SATA 6 Gbps support, Supports TRIM, 3-year warranty
Cons: Performance lower than expected, Warranty could be longer, No 3.5" adapter included, Needs a SATA 6 Gbps controller to perform best
Excerpt: For as long as I've been writing about SSDs, two issues are played back about the technology. It costs too much and the capacity is not enough. Your record is broken, throw it out. It's time to put your money where your mouth is. For the last few months high quality SSDs have reached the $1 per GB mark. You really can't ask for more than that. For those of you still holding out, let me tell you about the OCZ Agility 4.
