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. Additionally, the Aura Pro X2 is calibrated to consume only 5.7W during operation and to run cool.

The drive uses 3D TLC synchronous NAND flash memory with advanced SLC caching to deliver sequential data read and write speeds of up to 15 MB/s respectively-up to twice as fast as the factory-installed drives.

Designed for installation in a Mac Pro desktop computer (late 2013), this internal flash/SSD drive upgrade features a PCIe 3.1 x4, NVMe 1.3 interface and a custom blade form factor. Keep your edge with the Aura Pro X2 480GB NVMe SSD Upgrade from OWC / Other World Computing. NOTE: In certain circumstances, the read speed can slow down from 3000MB/s after a period of reads to 2000MB/s before returning to the peaks over 3000MB/s.OWC Aura Pro X2 480GB NVMe SSD Upgrade for Mac Pro (Late 2013) OWCS3DAPT4MP05P That's much faster than using 2.5-inch SSDs in the factory bays which top out at 275MB/s. The Aura Pro X2 measured 1528MB/s average transfer rate. We installed the Apple compatible PCIe carrier board in the 2010 Mac Pro tower's 4-lane PCIe slot 4. When plugged into the iMac Pro's Thunderbolt 3 port, we measured 1744MB/s average large sequential READ (2200MB/s peak). We installed it on an Apple compatible PCIe carrier board and mounted it in the AKiTiO Node Lite Thunderbolt 3 PCIe box. The Aura Pro X2 can also be used as fast external storage. You can always order the Aura Pro X2 bundled with the Envoy Pro bus-powered enclosure and use it for backup or archiving. You don't need to throw away your old PCIe flash storage. That's a lot faster than the original 2013 factory PCIe-based flash storage modules which topped out at 1000MB/s. It also is compatible with the Late 2013 Mac Pro 'Turbo Tube' although its 5.0 GT/s Link Speed limits the top speed to around 1500MB/s. Late 2013 to 2015 MacBook Pro 13-inch and 15-inch This is good news for owners of these models of Mac:

By upgrading your PCIe-based flash storage with the OWC Aura Pro X2, you can see up to a 59% increase in Large Sequential READ speeds and 98% increase in Large Sequential WRITE speeds.
