Frequently Asked Questions

This resource is crafted to help you find information easily and efficiently.

Can the ON900A be installed in my Mac?

The ON900A is specifically designed for Mac systems from 2013-2017, including MacBook Air (A1465, A1466), MacBook Pro Retina (A1502, A1398), Mac Mini (A1347), iMac (A1418, A1419), and Mac Pro (A1481). You must have macOS High Sierra 10.13 or later installed. Check your Mac model and year against the compatibility chart before purchase, as newer Macs may use different connectors.

Will my Mac's performance improve significantly after upgrading?

Absolutely. If your Mac is using a traditional hard drive or older SSD, the ON900A's 3,500MB/s read speeds will dramatically improve boot times, application launches, and file operations. You'll notice faster startup, quicker photo/video editing, and more responsive multitasking. The PCIe Gen3.0×4 interface maximizes your Mac's existing performance potential.

Will the ON900A overheat in my MacBook?

The ON900A is engineered for Mac's thermal constraints with efficient 3D TLC NAND Flash technology that generates minimal heat. The M.2 2280 form factor fits perfectly within Mac's existing thermal design. However, ensure proper ventilation during intensive tasks like video rendering or large file transfers to maintain optimal performance.

Can I migrate my existing macOS installation to the ON900A?

Yes, you can clone your existing drive to the ON900A using Time Machine backup restoration or disk cloning tools like Carbon Copy Cloner. The process preserves your applications, settings, and files. However, we recommend a clean macOS installation for optimal performance, then restore your data from Time Machine backup.

What is the actual usable capacity of the ON900A?

256GB version: approximately 238GB usable

512GB version: approximately 476GB usable

1TB version: approximately 931GB usable

2TB version: approximately 1.86TB usable

(System formatting and binary conversion consume some space, which is industry standard)

How reliable is the ON900A for professional Mac workflows?

The ON900A features enterprise-grade 3D TLC NAND Flash with TRIM, NCQ and S.M.A.R.T support for professional reliability. It's ideal for Final Cut Pro, Logic Pro, Adobe Creative Suite, and other demanding Mac applications. The consistent performance ensures smooth 4K video editing and large project file handling.

Why doesn't my Mac reach the advertised 3,500MB/s speed?

Achieving maximum speed requires:

①Compatible Mac model with PCIe Gen3.0×4 support

②macOS High Sierra 10.13 or later

③Large sequential file transfers (small files are affected by system overhead)

④Proper installation in the primary M.2 slot

Older Mac models or different PCIe configurations may limit speeds. These are system limitations, not product defects. The included installation tools help ensure proper setup.
