However, we wanted to improve upon the Accelsior&#8217;s design by offering both internal <em><strong>and<\/strong><\/em> external storage capability, so earlier this week we announced the <a href=\"https:\/\/eshop.macsales.com\/shop\/SSD\/PCIe\/OWC\/Mercury_Accelsior\/RAID\">OWC Mercury Accelsior_E2<\/a>.<\/p>\n<p>This new Accelsior model again offers extremely fast internal storage and adds fast external storage capability with the addition of two 6Gb\/s eSATA expansion interfaces. Now you truly can have the best combination of speed, capacity, and connectivity for simultaneous internal and external storage performance.<\/p>\n<p>And you aren&#8217;t limited to needing to have an available PCIe slot in a Mac Pro or PC to benefit from the Accelsior_E2. By installing it into an OWC Mercury Helios Thunderbolt expansion chassis, you can turn the Accelsior_E2 into the ultimate external SSD for Thunderbolt technology enabled Mac mini, iMac ,and MacBook machines.<\/p>\n<p>&#8220;So, how does it perform?&#8221; you might be asking yourself.
