File Allocation Table (FAT32)įAT32 is older and less efficient than NTFS.

NTFS is the ideal filesystem for internal drives. NTFS is the most modern file system that Windows uses by default for its system drive and non-removable drives. The HFS+ filesystem, also known as Mac OS Extended, is used by Apple to encrypt removable media on older versions of macOS. The APFS is the default used in the newer Mac operating system, also known as macOS 10.13 High Sierra - and is optimized for flash drives. Windows also supports exFAT, along with NT File System (NTFS) and File Allocation Table (FAT32).ĭifferent filesystem types will impact your encryption options in different ways. Your filesystem organizes your drive by dictating how and how much data is stored, and what type of data can be attached to files.Īpple supports three file systems: Apple File System (APFS), Hierarchical File System (HFS) Plus, and extended File Allocation Table (exFAT). Encryption, flash drives, and filesystemsĪn important factor in the encryption process for your flash drive is your filesystem. So even if your flash drive falls into the wrong hands, those unintended third parties won’t be able to access or understand the information the drive is holding and therefore would be unable to use it for nefarious purposes. For instance, non-encrypted flash drives can leave you vulnerable to malware and other device security threats.īut what does it really mean to encrypt your data and how does it work? Encryption means only those with an encryption key file or password will be able to access the data on an encrypted flash drive. If you’re going to use a flash drive, encryption is one of the best ways to protect your data.Įncryption can help protect the sensitive data on an external drive should it fall into the wrong hands through loss or theft, but there are other reasons for encryption, too. But what if the personal data stored on your flash drive is exposed? While this external portable device is compact and easy to carry, it’s also easy to lose or have stolen for those same reasons. Also known as thumb drives, flash drives are small, portable data storage devices that you can slip into your pocket.Ĭonvenient? Yes. If you’re looking for an easy way to carry or back up your digital data, a USB flash drive may offer you a cheap solution.
