Features and Specifications
Direct from OCZTechnology.com’s product page for the Agility 4 256GB.
Features
 |
No compression-related performance limitations
Better performance with “real world” datastreams of varying “compressibility” as well as fully incompressible data such as videos and multimedia files, encrypted data, archive files such as .ZIP files and software.

 |
Indilinx InfusedTM Everest 2 platform
Leading edge dual-ARM controller architecture enables faster performance like nothing else you’ve experienced.
|
 |
Fast boot times and ultra-low latency
Boot up in as little as 9 seconds, and industry-low latencies of .04 reads and .02 writes enable superior multitasking and flawless performance
|
 |
Ndurance 2.0 Technology
Advanced suite of NAND Flash management to increase durability and reliability to expand the NAND’s lifespan
|
The first line there refers to one of the issues that Sandforce controllers have. They’re amazingly fast for compressible data, but if the data is already compressed they slow way down. Indilinx controllers don’t have that issue. The latency numbers aren’t labeled as to what unit of measure they’re using, I’m guessing milliseconds. Fast boot times are great, in any case. The Ndurance 2.0 Technology sounds pretty good to me.
| Performance | 256 GB |

| Sequential Writes1 | 410 MB/s |
| Random 4k Read IOPS2 | 48,000 IOPS |
| Random 4k Write IOPS2 | 85,000 IOPS |
That’s awfully fast for a drive in the “mainstream performance” bracket. We’ll see how it really does later.

1GB of cache! Probably just on the 512GB drive. This makes me feel old, I remember my first 1GB HDD. It had a huge amount of storage space!

2 million hours eh? At idle maybe, even with good flash lifespan prolonging techniques (not including baking it) no drive is going to last 228.159 years. Actually I’m going to go out on a limb and so no way in hell is this going to last 228 years. 50? Sure. 100? Maybe, though I doubt it. 228? No way. MTBF numbers are joke these days anyway.

This is one of the things I really like about SSDs, they’re durable and use very little power.

| Operating System | Windows XP 32-bit /64-bit; Windows Vista 32-bit / 64-bit; Windows 7 32-bit / 64-bit; Linux; Mac OS X |
Read: Anything with a SATA port and support for it.
| Additional Features | |
| Performance Optimization | TRIM (requires OS support), dynamic and static wear-leveling, background garbage collection, Indilinx nDurance 2.0 Technology to extend SSD lifespan |
| Other Performance Features | Ndurance 2.0 Technology (Reduced Write Amplification without Compression, Advanced Multi-Level ECC, Adaptive NAND Flash Management) |
| Service & Support | 3-Year Warranty, Toll-Free Tech Support, 24 Hour Forum Support |
228 year MTBF and a 3 year warranty. OCZ doesn’t expect them to go two centuries either! My (rare) personal experiences with OCZs warranty service have been excellent though, which is refreshing compared to some.
Picture time!
