Keep your edge with the Aura Pro X2 240GB NVMe SSD Upgrade Kit from OWC / Other World Computing. Designed for installation in select September 2013 and later 27" & 21.5" iMacs, this internal flash/SSD drive comes complete with tools, display tape, and installation components. It features a PCIe 3.1 x4, NVMe 1.3 interface and a custom blade form factor, and uses 3D TLC synchronous NAND flash memory with advanced SLC caching to deliver sequential data read and write speeds of up to 2979 and 1219 MB/s respectively—up to twice as fast as the factory-installed drives. Additionally, the Aura Pro X2 is calibrated to consume only 5.7W during operation and to run cool.
The Aura Pro X2 is designed for macOS High Sierra 10.13 and later, taking full advantage of the advanced features of APFS, including strong encryption, copy-on-write metadata, space sharing, cloning for files and directories, snapshots, fast directory sizing, atomic safe-save primitives, and improved file system fundamentals. The drive reserves 7% of its overall capacity as free space to perform background maintenance tasks that optimize the health, performance, and endurance of your flash drive.
