SSD’s do not use moving parts so there is less risk for damage. There’s no shock protection, but so long as you’re careful when travelling, it shouldn’t be a concern. The drive is compatible with Mac, PC, and even Android.
External Drive And Pc Mac OS Extended FileWith the release of the macOS High Sierra operating system, Cupertino ditched its venerable Mac OS Extended file system, commonly abbreviated as HFS+, and switched to an entirely new file system. A portable drive draws power from your computer, so you won’t need a power outlet, plus these drives easily fit in laptop backpacks.An external drive's file system is the most important factor that determines whether or not it's readable by Macs, PCs, or both. Typically you’ll get more capacity for the price with desktop external hard drives for Mac, which you can store on computer desks. Mac.You’ll find desktop and portable external hard drives. Most Affordable Thunderbolt External Drive Buffalo MiniStationBefore we get to Thunderbolt 3, we need to address a basic building block of hard drives that has always affected compatibility, and probably always will: the file system.The default GUID partitioning scheme wont be recognised by 32-bit Windows XP and earlier Windows operating systems and Mac OS X versions earlier than 10.4.![]() External SSDs also have lower capacity limits, with most drives topping out at 2TB. You could pay more than 25 cents per gigabyte for an SSD, while spinning drives can be had for less than 10 cents per gigabyte—and often much less. (See our overall picks for favorite external SSDs.)One major downside, however, is that they're more expensive. Portable drives don't have a power plug they get the juice they need to run through their data interface. Desktop-style external hard drives are larger, are based on the beefier and more capacious 3.5-inch drives used in full-size desktop PCs, and require their own AC power source. These come in both portable and "desktop" versions.The portables are obviously smaller, and are based on the kinds of 2.5-inch platter drives used in laptops. You'll pay handsomely, of course—some Mac-specific arrays cost thousands of dollars.On the other hand, if you're looking to buy an external drive mainly to back up your files ( which you should definitely do) and it will rarely leave your home office, an inexpensive spinning drive will work just fine. (Or both it depends on how the array is set up.) The result is that you can get SSD-like speeds, with throughput of more than 400MBps, and capacities that top out close to 50TB. An array contains two or more drives that all work together to increase throughput, or guard your precious files against corruption via drive redundancy if one of the drives fail. Bitmap editor for macEven some Mac-specific drives are still sold with USB 3.0 connectors. (See our deep dive on the differences between Thunderbolt 3 versus USB-C.)Unfortunately, you won't find all that many Thunderbolt 3-compatible drives on the market. The silver lining is that Thunderbolt 3 via USB Type-C supports a blazing maximum potential throughput of 40Gbps, double the speed of the old Thunderbolt 2 standard and many times the 5GBps that USB 3.0 offers. But what happens when you throw yet another variable into the mix: the connection between your drive and your Mac? As you might have guessed, the answer is more tradeoffs.Every current Mac laptop comes with oval-shaped USB Type-C ports that support Thunderbolt 3, but other than a headphone jack, they are the only connectivity options available, which means you'll need an adapter to plug in any device that doesn't have a USB Type-C cable. Drives with rated peak reads and writes in the 1,000MBps to 3,500MBps range indicate one of these newer-tech drives. These kinds of components in newer drives help Thunderbolt 3 reach more of its speed potential. While older external SSDs have been limited by the internal electronics (generally a drive and controller using the older Serial ATA bus inside the drive), late-model drives use different internal components, based on PCI Express drives using the NVMe protocol. That's more than fast enough for backups and occasionally transferring multi-gigabyte files, but many times lower than Thunderbolt 3's maximum throughput.However, that speed ceiling is rising. Until recently, most external SSDs topped out at around 600MBps, for instance, due to the traditional bus types in that drives inside the chassis used. ![]() So, Which Drive Should I Buy?We've selected a few of our favorite drives for Macs below for more, check out our main list of best external hard drives and our top picks for SSDs. Many others feature copious amounts of aluminum and industrial-chic styling to match the design cues of your MacBook or iMac. Some drives come in a variety of colors. (Check out our favorite rugged drives.)Finally, you might want to consider how the drive will look when it's plugged into your Mac.
