Best external drives 2026: Fast SSDs and roomy hard drives | PCWorld

Sensing a 2X trend here? Another rule of thumb: 1TB for travel and light backups, 2TB for mainstream photo/video libraries, 4TB+ for larger archives, 8TB+ for desk-bound bulk backup. Note that these are our minimum recommendations. The more the merrier, and the further back in time you can keep backups for. If you’re buying an HDD, the interface is relatively unimportant — even older 5Gbps USB offers more than enough bandwidth to accommodate the 300MBps that is as fast as a modern HDD can deliver data. Note that to run a 40Gbps USB4 external SSD, your PC needs to support the USB4 or the Thunderbolt 3/4/5 spec. And while cheaper than 80Gbps, it’s still not cheap. If you meet those criteria, the Adata SE920 will deliver you nearly 4GBps transfers, and at a slightly more affordable price than our previous pick for USB4, the OWC Express 1M2 — for example, $280 for a 1TB Adata SE920 versus $300 for the 1TB OWC drive. If you want a lot of capacity, the Adata SE920 is available with up to 4TB, but it’s currently in short supply and has become very expensive. In fact, the My Passport performs on par with the best of 2.5-inch hard drives we’ve tested, while being the best deal. If it’s a portable, high-capacity hard drive that you’re after — pick this one. Read our full WD My Passport, Works with USB C review ... Price When Reviewed: 4TB: $120 I 6TB: $110 I 8TB: $160 I 10TB: $270 I 12TB: $300 I 14TB: $430 I 16: $230 I 18TB: $250 I 24TB: $540 But do the math before you plunk down your hard earned money — you may find deals. Below you can see the phenomenon in terms of a WD 2.5-inch HDD. The worst value for an external hard drive is typically the lowest-capacity drive. ... Above you can see the general more capacity, cheaper per terabyte trend.
