A desktop hard drive with a single platter-based mechanism inside, or a portable hard drive, is far more likely to make use of plain old USB instead. Almost every recent drive we have reviewed supports USB, and the same goes for laptops and desktops. USB ports are ubiquitous, and many external drives now come with cables with both rectangular USB Type-A connectors and oval-shaped USB Type-C ones to enable adapter-free connections to PCs that have only one type. If the drive includes only a single cable, you may need an adapter, depending on your computer's available USB ports. Be mindful of that.

Despite its name, the Seagate FireCuda Gaming Hub is also good for storing movies, photos, and most any other files you might want to store. And it fits in with any gaming setup with its cool RGB lighting. You'll only see the speed benefits of Thunderbolt, however, if you have a drive that's SSD-based, or a multi-drive, platter-based desktop DAS that is set up in a RAID array. For ordinary external hard drives, Thunderbolt is very much the exception, not the rule. It tends to show up mainly in products geared toward the Mac market.

The 2022 iteration of the LaCie Mobile Drive is a good choice for anyone who values capacity over speed, and who appreciates a rare touch of elegance in a platter-based hard drive. It costs a tad more per gigabyte than much of its platter-based ilk, but less than SSDs of equivalent capacity. Thunderbolt ports, should you need to daisy-chain storage, devices and display. This is particularly useful at the high end of the market where creative professionals are particularly fond of this port Cloud functionality, which allows individuals and businesses to operate a personal cloud. Essentially your very own cloud storage solution. The only case with hard drives where the USB standard matters much is if you connect a drive to an old-style, low-bandwidth USB 2.0 port, which is better reserved for items like keyboards and mice. (Also, if it's a portable drive, that USB 2.0 port may not supply sufficient power to run the drive in the first place, so the speed shortfall may be moot.) Any remotely recent computer will have some faster USB 3-class ports, though.

Need Redundancy or Extreme Speed? Consider a RAID-Enabled Drive

Hard drives may get you more capacity for your dollar by far, but first you need to consider a major difference in external storage these days: the hard drive versus the SSD.

The drive comes preloaded with Buffalo's "ModeChanger" utility for Windows and Mac that switches it from Open to Secure and vice-versa. Mode switching takes less than a minute and the drive must be reformatted after that. The LaCie 2big RAID array promises the reliability and delivers the performance benefit you'd expect from 7,200rpm platters, magnified by the default RAID 0 setting, while the optional RAID 1 setting is available if you want data redundancy. (A JBOD mode is also available if you don't want to use RAID.) Who It's ForThe next size up for consumer desktop drives is about the same height but twice as wide, to accommodate more than one platter-based hard drive mechanism in the chassis. These larger models are more expensive but also much more capacious—think 24TB or more (in that case, populated by two 12TB drive mechanisms). In the case of these and single-platter-drive products, you're not meant to swap out the drive or drives inside. (Credit: Zlata Ivleva)

Solid-state drives (SSDs) have fewer moving parts than traditional hard drives, and they offer the speediest access to your data. Unlike a conventional disk-based hard drive, which stores data on a spinning platter or platters accessed by a moving magnetic head, an SSD uses a collection of flash cells—similar to the ones that make up a computer's RAM—to save data.

Perhaps the only thing you don't need to pay all that much attention to is the warranty. Sounds counter-intuitive, perhaps? Sure, a long warranty is nice. But if your drive breaks because you dropped it, the warranty likely won't cover that, anyway. Even if the drive fails because of a manufacturing defect, most warranties simply replace the drive and don't cover the cost of recovery services that attempt to rescue your data from the broken drive. The real value lies in what's on your drive, not the drive itself.
