The 18TB d2 Professional USB-C 3.2 Gen 2 External Hard Drive from LaCie features a USB-C 3.2 Gen 2 port that's compatible with devices that use the USB-C interface, including Thunderbolt 4 and 3, USB4 and 3.0, and more devices. Inside is a Seagate IronWolf Pro enterprise-class drive, which spins at 7200 rpm and offers data transfer rates of up to 260 MB/s. The drive is pre-formatted as exFAT, which allows for compatibility with both macOS and Windows systems. If you're using the drive with only one operating system, you can optimize the drive's performance by reformatting it as NFTS for Windows or HFS+/APFS for macOS.
