Since macOS has supported standard NVMe drives for over a year and a half, there's no need for the OWC Aura Pro X2's hardware to differ from typical M.2 SSDs in any way other than the physical form factor. However, I've been using one in my personal 13' MacBook Pro for several months with no trouble so far other than a bit of creaking in the bottom panel when there's too much pressure near the SSD. These connectors weren't designed to bear the weight of the machine, so there's some risk of a mechanical failure leading to an unreliable connection. In Apple's laptops, these adapters are just a hair too thick, so closing the machine back up completely leaves the bottom panel bulging slightly and puts pressure on the adapter and SSD connector. The Apple PCIe SSD form factor is a bit longer than M.2, so it's possible to use a standard M.2 NVMe SSD and a dirt-cheap passive adapter.

OWC doesn't have a complete lock on this upgrade market.

HP EX950 and adapter compared to OWC Aura Pro X2 The price disparity is even worse at 2TB, which may be the most important capacity for the Aura Pro X2 since Apple never offered a 2TB SSD in this form factor. The Aura Pro X2 currently starts at 26Вў/GB, when M.2 SSDs with the same hardware are retailing for just over half that price. The downside to the OWC Aura Pro X2 is that as it's a niche product, retail pricing is well above commodity M.2 SSDs. With the Aura Pro X2, OWC can now offer performance and capacity far beyond what Apple's factory-installed SSDs could provide. Micron and Silicon Motion have since fixed their performance issues and the current generation of SSDs with 64-layer Micron 3D TLC and Silicon Motion SM2262(EN) controllers are serious competitors at the high end of the consumer SSD market, and a big step up from anything that was available in the 2013-2015 time frame. Unfortunately, Micron's first-generation 3D NAND and Silicon Motion's first-generation NVMe controller were both disappointing performers, so the Aura Pro X was again not a clear upgrade over the Samsung-based Apple original SSD. OWC responded with the Aura Pro X SSD, based on Micron 32-layer 3D MLC NAND and the Silicon Motion SM2260 NVMe controller.

This allowed OWC to provide a functional drop-in replacement that could offer higher capacities, but it was a big step backward in performance (and probably power efficiency, but we didn't get the chance to test it).ДЄpple eventually added a standard NVMe driver to MacOS, albeit after retiring upgradable internal storage from almost all of their product line. Rather than use an outdated AHCI PCIe SSD controller comparable to the ones in the early Apple PCIe SSDs, OWC put two SATA SSD controllers and a RAID controller onto one card.

Their first Aura SSD hit the market back when Mac OS X didn't include a standard NVMe driver, so the Aura had to present a standard AHCI interface. The Aura Pro X2 isn't OWC's first attempt to offer an upgrade for Apple PCIe SSDs, but it's the first one that does the job well. The Aura Pro X2 is sold either as a bare drive, or in an upgrade kit that includes an external USB enclosure for the Apple original SSDs it replaces. This is a modern high-end SSD with 3D TLC NAND and the latest Silicon Motion SM2262EN controller, with the reference M.2 PCB layout adjusted to fit Apple's form factor.

OWC has offered several aftermarket SSDs in Apple's custom not-quite-M.2 form factor, culminating in the recent release of the Aura Pro X2 SSD. This is where Mac accessory and upgrade specialist Other World Computing (OWC) comes in. So even though Apple's machines from 2013 through at least 2016 (depending on the model) included the fastest storage that money could buy at the time, those systems have been left behind as the NVMe storage market has matured from an exotic high-end novelty into the technology that's rapidly displacing SATA for mainstream computing. Apple's PCIe SSDs used a proprietary form factor rather than the M.2 standard that went on to become the standard for client PCIe SSDs. Apple's earliest PCIe SSDs used the AHCI protocol for compatibility with existing operating systems, but hardware compatibility was a very different story. Apple was an early adopter of PCIe SSDs, introducing them in 2013 when the NVMe specification was still in its infancy and before any NVMe hardware was available.
