Will it fit my laptop?

It fits any system with a standard 2.5-inch SATA bay that accepts a 7mm-high drive. Check your model's bay before buying; M.2-only machines need a different drive.

Is it faster than the hard drive in my old laptop?

Yes. A SATA SSD cuts boot and app-load times sharply compared with a spinning hard drive. It will not match an NVMe drive.

Can I use it as my main boot drive?

Yes. It works as a primary boot drive in systems that support 2.5-inch SATA storage. You will need to install or clone an operating system onto it.

Does it work in a mid-2012 MacBook Pro?

Yes, the 13-inch and 15-inch mid-2012 non-Retina models take a 7mm 2.5-inch SATA drive. Retina models use a different connector.

Can I put it in an external enclosure?

Yes. A 2.5-inch SATA enclosure turns it into portable USB storage.

What comes in the box?

The drive itself. Cables, brackets and cloning software are not included, so check whether your system needs a caddy or adapter.
