Built to the same exacting standards as all OWC SSDs, Neptune makes upgrading your computer an easy, smart decision. Get ready to love your computer again.

Life in the fast lane

From booting to browsing, launching apps and editing projects, upgrading your factory drive to a Neptune SSD puts your computer's performance back in the fast lane, with internal speeds up to 511MB/s. Neptune SSDs are built with technologies that outperform your computer's spinning hard disk, but without a single moving part. It makes for internal storage that's not just faster, but far more rugged and reliable than your computer's hard drive today.
