OCZ Agility 4 256GB Review (Page 1 of 10)

Just because some things are equivalent, does not mean they are the same. In the same way no one refers to "8 Mile Road" as "12.8748 Kilometer Road", or say "Give them 2.54 cm and they will take it 1.609 km" instead of "Give them an inch and they will take it a mile", just because two SSDs have equivalent capacity, does not mean they are the same. A while back, we have reviewed the OCZ Vertex 4 256GB, featuring an Indilinx Everest 2 controller and sixteen NAND flash chips for 256GB of storage capacity. Today, we are going to review the OCZ Agility 4 256GB, featuring an Indilinx Everest 2 controller and sixteen NAND flash chips for 256GB of storage capacity. Wait... what? Well, ask any enthusiast and we can tell you with confidence, the grade of memory ICs used under the hood is absolutely crucial to the numbers it puts out in our benchmarks -- just like how the OCZ Vertex 3 Max IOPS 240GB and OCZ Agility 3 240GB is clearly not the same thing. The former is quite a bit faster than the latter, despite its similarities. Of course, life is not just about speed. Factors such as price and power consumption can also be very important. What merits does the mainstream oriented OCZ Agility 4 256GB SSD put on the table today? Read on to find out!

Our review unit of the OCZ Agility 4 256GB came in a medium sized, corrugated cardboard box from the company's American headquarters in Sunnyvale, California. Using UPS Saver, the transfer was quick and painless as always -- traveling two thousand kilometers across the border in less than twenty four hours. As always, UPS did a great job in ensuring everything is handled with care. I know, that sounds kind of funny, but they have been pretty darn good to us, haha. We here in Calgary excitedly opened the package with the camera ready, and got straight to work.

We have seen this type of retail packaging used with OCZ's solid state drives before. No, it is not the standard box used with the company's performance OCZ Vertex 4 line. Instead, it takes on the simplistic rather simplistic approach we have previously seen with the Octane. Enclosed by what that appears to be a blister pack -- thank goodness it is actually plastic shell with two button clips at the top -- this appears to the the standard for OCZ's value and mainstream drives. The clean layout allows you to grab all the information you need at first glance; the OCZ Agility 4 256GB SSD itself is shown prominently in front, capacity at the bottom left, and an "Indilinx Infused" logo in place of the ever-so-popular "SandForce Driven" logo at the upper right corner. Detailed specifications is not found on the outside, but we have them here, as taken from the manufacturer's website:

Popping the packaging open, there isn't a whole lot of stuff included. Other than the SSD itself, clipped inside the background insert is an installation/warranty guide, and the smug-as-always "My SSD is faster than your HDD" sticker from OCZ. No cables, no adapter brackets, just pure Agility 4. With that in mind, let's take a closer look at the solid state drive itself.
