LaCie Rugged RAID Pro is delivered formatted in exFAT for compatibility with both Windows and Mac computers. If you use the drive with only one type of computer, you can optimize file copy performance by formatting the drive in the native file system for your operating system—NTFS for Windows or HFS+ for Macs. There are two ways you can optimize performance:
Toolkit Optimize—Format your drive for optimal performance with just a few simple clicks.
Manual formatting—Use Disk Management (Windows) or Disk Utility (Mac) to format your drive in non-native formats.
NTFS—The native file system for Windows. macOS can read NTFS volumes but cannot natively write to them.
Mac OS Extended (HFS+)—The native hard drive file system for macOS. Windows cannot natively read or write to HFS+ (journaled) volumes.
exFAT—Compatible with Mac and Windows. exFAT is not a journaled file system which means it can be more susceptible to data corruption when errors occur or the drive is not disconnected properly from the computer.
FAT32—Compatible with Mac and Windows. However, FAT32 is a legacy file system designed for low capacity hard drives and it is not recommended for modern hard drives or operating systems. A FAT32 partition can reach up to 32GB when formatted on a Windows PC.
|Use NTFS if:|
|…you connect the storage device to Windows computers, and you don’t need to allow a Mac to write to the disk.|
|Use HFS+ if:|
|…you connect the storage device to Mac computers, and you don’t need to allow a Windows computer to read or write to the disk.|
|Use exFAT if:|
|…you need to allow both Mac and Windows computers to read and write to the disk.|
|You can use FAT32 if:|
|…you connect the storage device to older Windows and Mac computers. FAT32 is not recommended for modern operating systems and computers.|
Use Toolkit Optimize to format your drive for optimal performance with your operating system’s native file format— NTFS for Windows or HFS+ for macOS. File transfer rates can be significantly better with the native format.
OPTIMIZE—Let Toolkit choose the optimal format for your computer system and configure the volume for you with just a few clicks.
FORMAT—Opens the disk management utility for your operating system, which you can use to manually format your drive. Use this option if you want to format the drive in non-native formats.

macOS version 10.11 or later
|macOS 10.13 and later—Make sure to select the disk and not just the volume. If you don’t see two entries listed in the sidebar, change the view in disk utility to show both the drive and the volume. The view button is in the upper left side of the Disk Utility window. Change the view to Show All Devices. This feature was introduced in macOS 10.13 and is not available in 10.11 or 10.12.|
