Time Machine Compatible External Wireless Hard Drive Reviews
Ownership an external hard bulldoze or SSD for your Mac is not all that different from buying one for your Windows PC. Virtually laptops with either operating system now come with at least 1 oval-shaped USB-C port, and it's the one yous'll want to use for connecting your external drive. The principal difference is that many drives made specifically for Macs use the upgraded Thunderbolt data transfer protocol, which promises super-fast data transfers for photographers and video editors who need to store mountains of footage and admission it very quickly. As a result, they are typically external SSDs, or even multidrive RAID arrays, which means they also tend to exist expensive.
So what'southward a Mac user to exercise who simply wants to support his or her files using Time Machine, or stash a large video collection? Spoiler: A Thunderbolt drive isn't your simply option; far from information technology. In fact, in many cases it makes sense to choose an inexpensive non-Thunderbolt drive that isn't targeted toward Mac use. Read on as we solve this and all of your other Mac external-storage quandaries.
Understanding File Systems: HFS+, APFS, exFAT, and More
Before we get to Thunderbolt, we demand to address a basic building block of hard drives that has always affected compatibility, and probably e'er volition: the file system.
An external bulldoze's file system is the most important factor that determines whether or non it's readable past Macs, PCs, or both. Starting with macOS "High Sierra," Cupertino ditched its venerable Mac Os Extended file organisation, commonly abbreviated as HFS+, and switched to an entirely new file system. It'south simply called the Apple tree File Arrangement (APFS), and information technology's the kickoff format to be used across both Macs and iOS devices.
At that place are many benefits to switching from HFS+ to APFS, including ameliorate security thanks to native encryption, but the most important thing to note for external-drive shoppers is backward-compatibility. Whatsoever drive formatted with HFS+ volition work just fine with a Mac that's running High Sierra or later.
Neither Apple tree File System nor HFS+ works with Windows, however. If you plan to use your external bulldoze with computers that run both operating systems, you should consider formatting your drive with the exFAT file system. Yous won't go the security and efficiency of APFS, only you will become the convenience of being able to transfer files back and along between Windows and macOS simply by plugging in and unplugging your bulldoze.
Of form, you can easily wipe and reformat virtually external drives, and then you're non express to ownership only those intended for use with Macs. If you really fancy a consumer-oriented drive formatted for Windows (which will ordinarily come pre-formatted in the NTFS format), you tin employ the Deejay Utility in macOS to reformat information technology later you bring information technology home from the shop. Some highly specialized external drives might non work with Macs even if they're formatted correctly, but consumers looking for extra infinite simply to store backups or large video collections aren't probable to encounter them.
External Drives: SSDs vs. Spinning Platters
Once you've settled on a file system, you then take to make up one's mind which storage medium you lot want: solid-state or spinning disk. Each has its advantages and disadvantages, and—dissimilar the file arrangement—the blazon you lot buy is the type you're stuck with for the life of the drive.
A solid-country drive (SSD) offers quick access to your data because information technology stores your bits in a blazon of wink memory rather than on spinning platters. SSDs are ofttimes smaller and lighter than spinning external drives, as well, which is likewise thanks to the lack of moving parts. Their small size means they can oftentimes fit into a jacket or pants pocket, which makes them a meliorate pick if you're looking for a portable external drive that you'll be conveying with you frequently. (See our overall picks for favorite external SSDs.)
Ane major downside, nevertheless, is that they're more than expensive. You could pay more than 20 cents per gigabyte for an SSD, while spinning drives tin exist had for less than 10 cents per gigabyte—and often much less. External SSDs likewise have lower capacity limits, with almost drives topping out at 2TB. Compare that with external spinning drives, which are like shooting fish in a barrel to find even in capacities in excess of 8TB for desktop-manner drives, or up to 5TB for portable ones.
For professional videographers who edit lots of 4K footage and gamers or movie buffs who have large libraries of multi-gigabyte titles, an external RAID array made up of multiple platter-based drives is worth because, since information technology combines the nearly-speed of an SSD with the gargantuan possible capacities of spinning drives. An array contains two or more drives that all work together to increase throughput, or baby-sit your precious files against corruption via bulldoze redundancy if one of the drives fail. (Or both; it depends on how the array is set up upward.) The result is that yous can get SSD-similar speeds, with throughput of more than 400MBps, and capacities that top out shut to 50TB. You'll pay handsomely, of class—some Mac-specific arrays cost thousands of dollars.
On the other hand, if y'all're looking to buy an external bulldoze mainly to dorsum up your files (which you should definitely do), and information technology will rarely leave your home function, an inexpensive spinning drive volition piece of work but fine. These come in both portable and "desktop" versions.
The portables are obviously smaller, and are based on the kinds of 2.five-inch platter drives used in laptops. Desktop-mode external hard drives are larger, are based on the beefier and more capacious iii.5-inch drives used in full-size desktop PCs, and require their own Air-conditioning power source. Portable drives don't have a power plug; they get the juice they need to run through their information interface.
Does Thunderbolt Matter in an External Drive, or Will USB-C Do?
So, to recap: Faster, smaller (both physically and in terms of gigabytes) solid-state drives come at a premium, while spinning drives offer a much better value while sacrificing speed. Just what happens when you throw yet another variable into the mix: the connexion between your drive and your Mac? As you might have guessed, the respond is more merchandise-offs.
Every current Mac comes with oval-shaped USB Type-C ports that support Thunderbolt speeds. The MacBook Pro models released in 2021 come up with the latest Thunderbolt 4 interface, while other recent Macs use the older Thunderbolt iii. Both have the same maximum 40GBps maximum throughput, many times the speed of regular USB-C ports.
Unfortunately, you won't find all that many Thunderbolt 3-compatible drives on the market, and even fewer that back up Thunderbolt four. There are even some Mac-specific drives even so sold with USB three.0 connectors. Moreover, the Thunderbolt drives you can purchase are constrained by the maximum throughput of the bulldoze itself, rather than the Thunderbolt interface. Until recently, almost external SSDs topped out at around 600MBps, for example, due to the traditional bus types used by the drives within the chassis. That's more than fast enough for backups and occasionally transferring multi-gigabyte files, but many times lower than Thunderbolt's maximum throughput.
All the same, that speed ceiling is rise. While older external SSDs have been express by the internal electronics (generally a drive and controller using the older Serial ATA bus within the drive), tardily-model drives use different internal components, based on PCI Express drives using the NVMe protocol. These kinds of components in newer drives aid Thunderbolt reach more than of its speed potential. Drives with rated height reads and writes in the 1,000MBps to three,500MBps range indicate one of these newer-tech drives. (Again, run into our roundup of the best external SSDs for more give-and-take of this.)
You can insist on Thunderbolt support if you know yous need all the speed you tin get, just a USB-C drive will be a better pick if you're more toll-sensitive, or need to as well use the drive with a PC. With USB-only drives, some manufacturers include a USB Type-C cable for people who own a USB Type-C-only Mac, and you lot can always option up a converter for a few dollars online if the drive you're eyeing doesn't offering i. And don't forget that the 27-inch iMac and Mac Pro yet come with USB iii.0 ports, then they won't crave adapters.
Other External-Drive Considerations
Drives intended for PCs sometimes come bundled with software that will automatically back up your files to the drive when it'due south connected, but such software isn't as much of a consideration for Mac users, who already take an excellent built-in backup choice in the grade of Time Machine. (Encounter our guide to using Fourth dimension Machine for backups.)
The get-go time you plug in an external drive, Time Car will enquire if yous want to use it as a backup drive. While yous can customize backup options in System Preferences, such as request Time Machine to exclude sure folders, there's no action required on your part if you lot're happy with the default settings. The next time you lot plug in your bulldoze, Time Auto will automatically set to work creating a backup.
Unless your drive is never going to leave your dwelling house or part, you should also consider its physical durability. Rugged, waterproof drives are a skilful option non just for surfers and BMX riders, as their marketing seems to advise, but also for people who are carrying their drives to and from schoolhouse or piece of work, where they might occasionally get spilled on or dropped on the floor. (Check out our favorite rugged drives.)
Finally, you might desire to consider how the drive will look when it's plugged into your Mac. Some drives come in a variety of colors. Many others feature copious amounts of aluminum and industrial-chic styling to lucifer the design cues of your MacBook or iMac.
