MacBook Airs ship with one of two models of SSD.  You either get a moderately fast Toshiba SSD or a significantly faster samsung drive with an updated controller. But for some, that’s not enough.

We’ve pointed out in the past that OWC provides a new SSD called the OWC Mercury Aura Pro Express 6G SSD, and it’s definitely something speed freaks will want to look into. AnandTech has reviewed the Mercury Aura Pro Express 6G SSD, confirming the benchmarks and blowing away just about any laptop or desktop SSD on the market.

AnandTech breaks it down:

As you can see in the chart above, the 6G SSD offers a 4KB  88.4 MB/s write and 30.4 MB/s read speed, and 128KB sequential write speed of 495.1 MB/s and read speed of 451.4 MB/s. Sadly, the SSD packs a SandForce controller which requires more power, so using this SSD adds up to 5% to battery drain on the notebook, but with these speeds we think you’ll get over it.

OWC makes 6G SSD available in both a 120GB and 240GB version, costing $280 and $550 respectively. If you’re big into speed this might be for you.  For all the details check out AnandTech’s review.
