It's slower on paper, but will operate at similar speeds to the Extreme Pro when connected to a USB 3.2 port.Īlso bear in mind that both these drives will be pre-formatted to work with both Windows and Mac. If you're using an older Intel-powered Mac, then we'd recommend the cheaper SanDisk Extreme Portable SSD V2 (non 'Pro') as a portable option. That means this SSD can still unleash its maximum speed potential of up to 2000MB/s, really putting the 'extreme' in Extreme Pro!Ĭapacities range from 500GB to 2TB, which isn't all that much by today's standards, but the payoff is that this is one of the very fastest external hard drives for an M1 Mac. This is linked to your Mac via the short-lived USB 3.2 Gen 2x2 connection - the USB generation that directly preceded the current USB 4 standard - but the USB 4 ports on an M1 Mac are backward compatible with USB 3.2 Gen 2x2. Although strictly speaking a portable hard drive rather than a device that lives on your desk, there's no reason why it can't be used in place of a bigger external desktop hard drive.Īnd while most external drives use older, slower mechanical hard disk drives to store your data, the Extreme Pro Portable SSD V2 is based around a blazing fast NVMe SSD.

Sadly, buying a hard drive that can utilise this tech is currently almost impossible, but this SanDisk drive is the next best thing. If you're rocking one of the latest M1 MacBooks or iMacs, you're able to connect a hard drive using the latest Thunderbolt 4/USB 4 interface.
