Instead of a box, the Agility 4 comes packaged in a plastic clamshell. While there aren't a lot of details on the front, the back of the packaging lists many of the Agility 4's key features including its SATA 6Gbps interface, TRIM support, MLC flash memory and Indilinx Ndurance technology. Inside the clamshell, you'll find the SSD, an installation guide and a sticker that says "My SSD Is Faster Than Your HDD."
Physical Features:
The Agility 4 looks very similar to OCZ's other 2.5" SSDs. The top of the outer casing is made out of plastic and has a matte black finish. There is also a green and black sticker showing that the SSD is part of OCZ's Agility series. The bottom of the casing is made out of metal with a brushed metal finish. The stickers on the bottom show the drive's part number, capacity and serial number.
As I mentioned earlier, the Agility 4 uses the Indilinx Everest 2 (IDX400M00-BC) controller chip. According to reports, this dual-core, ARM-based controller is based on a Marvell design. However, the firmware has been developed entirely by Indilinx. At this point, the only drives using the Everest 2 are OCZ's Vertex 4 and Agility 4 SSDs.
For the 256GB Agility 4, OCZ opted to use their own 16GB 25nm M2502128T048AX22 asynchronous NAND chips. Looking at the pictures above, you can see that there are eight of these chips on either side of the PCB. The drive also has two 256MB Hynix H5TQ2G63BFR-H9C DDR3 memory chips that are used for caching and garbage collection.
