OWC Mercury Extreme Pro 6G SSD Review (120GB)
by Anand Lal Shimpi on May 5, 2011 1:45 AM ESTAnandTech Storage Bench 2011 - Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).
The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:
| AnandTech Storage Bench 2011 - Light Workload IO Breakdown | ||||
| IO Size | % of Total | |||
| 4KB | 27% | |||
| 16KB | 8% | |||
| 32KB | 6% | |||
| 64KB | 5% | |||
Despite the reduction in large IOs, over 60% of all operations are perfectly sequential. Average queue depth is a lighter 2.2029 IOs.

doesn't the Z version let you access the CPU's video decoding/encoding engine while having an external GPU?While with the P and H versions you have to choose one or the other?

In considerin an SSD for an OS X boot volume should one be more concerned with compressible data or incompressible data? I wondering because I know OS X compreses some of it's OS files and presumably many apps do the same thing. Further I'm assuming the light workload test uses a windows simulation, can anyone say if/how that would differ from OS X?I'm probably more worried about it than I need to be but trying to decide between OCZ/OWC, Intel and Crucial and still not clear which is best for a dual drive setup in a MacBook pro.

"OCZ is still SandForce's favorite partner and thus it gets preferential treatment when it comes to firmware."I just confirmed with OWC, they're shipping the 6G with the 60K IOPS read/write frimware. Hope you update your article soon. This is kinda misleading, I'm reading comments here and people think that only OCZ drives have the 60K IOPS firmware.

I had the Crucial C300, OCZ Vertex 3, and the OWC Extreme 6G in my laptop on a Sata6G connection... and honestly I didn't notice a difference in speed between the three of them. Against the Vertex 2 and the Intel X-25, there was a slight difference. In the end, I decided to go with OWC Extreme 6G for one reason... **** FIVE YEAR WARRANTY ****!!! That's friggin' awesome... ONLY SSD to offer a 5 year warranty on an SSD. And costwise, they're around the same or lower as the rest of the competition.
