USB flash drives (a.ok.a. “thumb” drives) could appear passé in a world the place AirDrop and cloud storage resolve the file-transfer downside. However they’re nonetheless fairly helpful for handing over recordsdata to a different consumer when your Macs usually are not close by, for transferring very massive recordsdata, and extra. You may even use them to offer a PC consumer a file out of your Mac and vice versa.
Once you get a brand new flash drive, you’ll be able to plug it in and it’ll present up in your Desktop, no matter how the drive is formatted. (It’s possible you’ll be requested to permit the accent to connect when you’ve arrange macOS’s System Settings for Privateness & Safety > Equipment that means.) Nonetheless, you must take into account reformatting that drive earlier than you employ it. There are different codecs obtainable that may very well be higher suited in your wants.
On this article, we’ll go over the completely different codecs and why you’d choose one over the others. When you study concerning the codecs, you’ll be able to choose one and format your USB flash drive appropriately. In case you are out there for an exterior SSD system, learn our Finest Picks for Exterior SSDs.
What’s a file system format?
Earlier than we cowl the completely different file system codecs, it’s necessary to know what a file system format is within the first place. It’s principally the way in which a pc manages recordsdata on a storage system. Completely different working techniques (macOS and Home windows, for instance) help completely different file system codecs, and every format affords its personal options.
There are 4 completely different codecs you should utilize on a USB flash drive. The kind of file format you choose relies upon totally on what computer systems you propose to make use of the drive with. Some codecs can be utilized on completely different working techniques, whereas others can be utilized solely on one OS. It’s necessary to choose a format that most accurately fits how you propose to make use of the USB flash drive.
For Mac-only storage units: APFS
APFS is the Apple File System, which is at the moment the default format. It was created with flash drives and SSDs in thoughts. A majority of these storage units use chips that may put on out over time, although that will depend on how usually knowledge is written to the chips. For many customers, an SSD or flash drive will final past your potential to make use of it. To assist forestall put on and tear, APFS is designed with writing effectivity in thoughts to delay a tool’s well being.
APFS affords different options, similar to robust encryption, house sharing, snapshots, and extra. It additionally affords on-demand disk house allocation for a partition. Macs with inner SSDs have to be formatted with APFS.
Whereas APFS was made for SSDs and flash drives, it may be used with arduous drives, however a couple of experiences state that you could be expertise barely slower efficiency. You need to think about using Mac OS Prolonged as an alternative (see under).
These USB-A flash drives want a USB-C adapter for use on most trendy Macs.

APFS was launched in macOS 10.13 Excessive Sierra, so Macs working an OS older than that won’t be able to acknowledge an APFS-formatted drive. For these older Macs, you could use Mac OS Prolonged (see under).
Drives formatted with APFS can be utilized solely on Macs working macOS 10.13 Excessive Sierra or later. APFS drives can’t be used with Home windows PCs. Be taught extra about APFS.
For older Macs and Mac-only arduous drives: Mac OS Prolonged
Earlier than there was APFS, there was Mac OS Prolonged, often known as HFS+ (Hierarchical File System +). It was created at a time when arduous drives have been the dominant type of storage, internally or externally. It was launched in Mac OS 8.1 in 1998, when it changed HFS (Hierarchical File System), the unique Mac file format.
HFS+ lacks a few of the options of APFS that have been created to enhance effectivity on SSDs, so HFS+ could influence an SSD’s or flash drive’s velocity. Additionally, this lack of effectivity impacts the wear and tear and tear on flash reminiscence.
Since Mac OS Prolonged was created for arduous drives, it’s finest used for such, even on at the moment’s Macs. Any arduous drive, SSD, or flash drive that will likely be used on Macs with macOS 10.13 Excessive Sierra or older should use Mac OS Prolonged. Storage units for Time Machine have to be formatted with Mac OS Prolonged.
Storage units formatted with Mac OS Prolonged can be utilized solely on a Mac. If you’d like to have the ability to join a storage system to a Home windows PC, you could use exFAT or MS-DOS (FAT).
For Mac and Home windows: exFAT or MS-DOS (FAT)
If you wish to use your USB flash drive with each Macs and Home windows computer systems, you have got two file codecs to select from: exFAT or MS-DOS (FAT). “FAT” stands for File Allocation Desk, and exFAT is a more moderen model, whereas MS-DOS (FAT) is older.
MS-DOS (FAT)’s main limitations are that it can not retailer recordsdata bigger than 4GB, and its most partition measurement is 8TB. Nonetheless, MS-DOS (FAT) drives can be utilized on all variations of Home windows. ExFAT has a most file measurement and partition measurement of 128 petabytes, however it will probably’t be used on Home windows variations older than Vista.
Which one to make use of? Use MS-DOS (FAT) except you’re employed in video, massive databases, photos, or anything that creates massive recordsdata, or you have got a flash drive that’s bigger than 8TB and you do not need to divide it into a number of partitions. In actual fact, your USB flash drive might be already formatted with MS-DOS (FAT)–most are. In any other case, use ExFAT.
In case you are utilizing a Home windows PC to format a flash drive, you’ll discover a third alternative, NTFS. Macs can learn NTFS drives, however they’ll’t write to them with out particular third-party software program. Apple’s Disk Utility can not format drives as NTFS.
For different units: MS-DOS (FAT)
If you could use the flash drive with one other system, similar to a TV, use MS-DOS (FAT). For instance, you may wish to switch a video out of your Mac to your TV. Otherwise you downloaded recordsdata wanted to improve a tool with a USB port. Since MS-DOS (FAT) is so common, likelihood is these units are appropriate with it.
Decide a partition scheme
Okay, so that you’ve discovered which file format system to make use of. However wait! There’s another factor to determine: the partition scheme, or “Scheme” because it’s referred to within the Disk Utility app.
A partition in storage parlance is a bit of a storage system. For instance, you probably have an 8TB drive, you’ll be able to determine to format it into one partition of 8TB, and it could seem in your Mac as one 8TB drive. Or you’ll be able to determine to partition that drive into, say, two 4TB partitions, and then you definately would see two 4TB drives in your Mac. The scheme tells the pc how the recordsdata are organized.
Within the Disk Utility app, there are three schemes from which to decide on:
- GUID Partition Map: for all Intel and M-series Macs. Select this one if you don’t plan on utilizing the drive with a Home windows PC. Later variations of Home windows can use this scheme, however you’re higher off utilizing…
- Grasp Boot Document: this scheme works on Home windows PC and Macs.
- Apple Partition Map: use this provided that you’re going to make use of the drive on an outdated Energy PC Mac.
The way to format a USB flash drive
Formatting a USB flash drive (or any storage system) might be completed with the Disk Utility app, which is present in Functions/Utilities. These are the steps to format the drive.
- Time to finish: 5 minutes
- Instruments required: macOS (Sequoia proven right here; the steps are comparable in older variations)
- Supplies required: USB flash drive or different exterior storage system
