OWC has released SSD upgrades suitable for Apple's MacBook Air (our 2011 review). The SSDs are branded as Mercury Aura Pro Express 6G and come in capacities of 120GB and 240GB. OWC claims speeds of up to 507MB/s read and 454MB/s write, which is about twice as fast as what the Samsung SSD used in some MBAs provides. The SSD controller is the same as found in OWC's Mercury 6G SSDs: SF-2281. Prices are $350 and $600 respectively and they ship in 24 hours. 

In January, OWC released Mercury Aura Pro Express 3G series for 2010 MacBook Airs so this announcement is a logical follow-up of that. The SATA interface in 2011 MBAs is 6Gb/s, but Apple is using 3Gb/s SSDs. Hence OWC's Aura 6G SSD should guarantee a healthy performance boost in disk intensive tasks, although the difference will most likely be negligible in everyday operations. For most people, there is no reason to upgrade the SSD but in case you have for example the base 11" with 64GB SSD and more space is needed, OWC's offerings might come handy. There are no other SSDs suitable for 2010-2011 MBAs, unless you find an original part on eBay.
