OCZ Agility 4 256GB Solid State Drive
6 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.
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 wea...
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
Excerpt: Today, we have one of their latest drives on hand which is the Agility 4. The Agility is the second edition of an Indilinx controller after being purchased by OCZ. The controller is now called Everest or Everest 2 in case of the Agility.
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...
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.
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.
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
Conclusion: Overall the Samsung 830 comes out on top, it has the best performance especially when you look at the most important benchmark (PCMark 7). So if you are looking for an affordable 256 GB SSD, we would right now recommend the Samsung 830 and not 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.
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.
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
Summary: In the introduction of this article I talked about the two major complaints that seem to stick to solid state drives - price and capacity. There is another one and this one brings fear with it - reliability.
