The OWC Mercury Extreme Pro 6G 120GB SATA 3 SSD Review – This 120GB 6G SSD Absolutely Flies!

An SSD arrived earlier today that I thought all might like to read about.  A quick change of plans to the negative of a few and here we are taking pictures and benchmarking the new OWC Mercury Extreme Pro 6G 120GB SSD.

Having just completed testing, OWC gets a big thumbs up for being only the second manufacturer to release an SSD with SandForces new SF-2000 series SATA 3 processor as well as ensuring the ’6G’ is of the quality that we have come to appreciate.

INTRODUCTION

The OWC Mercury Extreme Pro 6G SSD is a SATA 3 solid state drive and available in capacities of 120, 240 and 480GB.  Initial pricing is expected to be in the area of $319.99 and $579.99 for the 120 and 240GB versions with the 480GB demanding a premium of $1799.  Performance for the 6G is equal for all capacities at 506MB/s read and 464MB/s write with 60,000 IOPS and .1ms disk access.

Exterior packaging of the OWC ’6G’ is just as we should be seeing with all SSDs.  The exterior plastic case affords a great view of the drive inside and the plastic opens easily without the need for scissors and a great deal of frustration as is the case with the 1 piece plastic packaging so common these days.

PHYSICAL CHARACTERISTICS

The exterior of the OWC 6G is solid metal with smoothed edges and the distincive OWC blue color.  The sticker on back identifies the SandForce SF-2281 processor within, firmware revision as well as the typical warning that any tampering or removal of the seal will automatically void the warranty.  Thats why we like to get a close up look at the heart of the 6G here.

Inside the OWC Mercury Extreme Pro 6G 120GB SSD lies the best in solid state drive technology today.  The controller is the SandForce 2281 SATA 3 controller and RAM is 16 chips of 8GB 25nm Synchronous Tier 1/Grade A NAND for a total raw capacity of 128GB.  The firmware, however, allocates 7% (1x8GB chip) of storage to over provisioning which improves the lifespan and performance of the SSD.  This brings the total available to 120GB which is then formatted leaving the final available user capacity at 111GB.

A little known characteristic that demonstrates just how advanced technology has become is evident if a cell or block goes bad within the SSD. The SSDs firmware will automatically recognize the problem, designate the equal amount of space from the over provisioned area and then simply remap without any capacity or data loss.

    I work for a distribution company that has received the OCZ Vertex 3 about 2 weeks ago and also supplies the OWC SATA III drives. The situation with OCZ was and is that OCZ has had compatibility issues and therefore deliveries were delayed by a few weeks. We have however already had 15 units and feedback from customers was good. Currently there are 2 companies (OWC, OCZ) which provide the new SATA III SSDs with sand Force Controls and OWC has achieved slightly better results than OCZ and is slightly cheaper. Photofast, a Taiwanese manufacturer will release a SATA III SSDs, but is currently stuck, as the controller is not a Sandforce controler but a Japanese manufacturer, who can not supply at the moment.

    At best you are looking for the other topic “SSD OCZ OWC Europe” for comparison and perhaps someone has the discs in stock.

    Forget benchmarks as this drive may lag in some benchmarks but outperform in others. In real world use, this drive hauls but. I’ve used the Crucial C300, Vertex 3, and OWC 6G all on a Sata6 connection… and I couldn’t tell much difference in their use (I used each one for a week to fully get used to each drive). In the end, I decided on the OWC drive for a simple reason… *** FIVE YEAR WARRANTY ***
