Best External Hard Drives (2026): SSD to Store Data, Video, and More

2026年最佳外置硬盘：存储数据、视频及更多内容的固态硬盘 (SSD)

If you’re running out of storage space on your laptop or you need to back up your data or store that backlog of videos you’re going to edit one day (I am, I swear), an external hard drive can solve your problem. The trouble is, there are hundreds of drive options ranging from dirt cheap to crazy expensive, so how do you know which one is right for you? I’ve tested dozens, across operating systems and with different uses in mind, to find the best external hard drives for storage, backups, gaming, video editing, network-attached storage (NAS) devices, and more.

如果你的笔记本电脑存储空间不足，或者你需要备份数据、存储那些打算某天剪辑的视频积压（我发誓我确实有），那么外置硬盘可以解决你的问题。问题在于，市面上有数百种硬盘选择，价格从极其便宜到贵得离谱不等，你该如何选择最适合自己的一款呢？我测试了数十款产品，涵盖了不同的操作系统和使用场景，旨在为你找出最适合存储、备份、游戏、视频剪辑、网络附属存储 (NAS) 设备等用途的最佳外置硬盘。

Updated July 2026: I’ve removed some discontinued drives and added the SanDisk G-Drive ArmorATD because, let’s face it, with SSD prices climbing, spinning drives are much more compelling than they were a year ago. I’ve also updated prices and links throughout.

2026年7月更新：我移除了一些已停产的硬盘，并加入了 SanDisk G-Drive ArmorATD。说实话，随着固态硬盘 (SSD) 价格不断攀升，机械硬盘 (HDD) 比一年前更具吸引力了。此外，我还更新了文中的价格和链接。

Best for Backups

最佳备份硬盘

The AI race and its attendant flurry of memory-hungry data centers are causing prices to skyrocket, with apparently no end in sight. Drives in this guide have tripled in price in the past six months. For example, 8-TB SSDs are selling for more than the price of a new MacBook Air, which itself has gone up $200 to help cover surging memory costs.

人工智能竞赛及其伴随的、对内存需求巨大的数据中心热潮导致价格飙升，且目前看来短期内不会停止。本指南中的硬盘价格在过去六个月里翻了三倍。例如，8TB 固态硬盘的售价已经超过了一台新款 MacBook Air，而后者为了应对内存成本的激增，自身价格也上涨了 200 美元。

You know what data centers don’t seem to need, though? Spinning drives. While their prices have crept up some, these older drives remain affordable and are your best choice for backups anyway. For incremental backups, which we recommend, speed isn’t a huge factor.

不过，你知道数据中心似乎不需要什么吗？那就是机械硬盘。虽然它们的价格有所上涨，但这些老式硬盘依然经济实惠，且无论如何都是你进行备份的最佳选择。对于我们推荐的增量备份而言，速度并不是一个关键因素。

I have been using a variation of the Elements desktop hard drive to make backups of my data for more than a decade. These drives are big and require external power, but they’re some of the cheapest and most reliable I’ve used.

十多年来，我一直使用 Elements 系列桌面硬盘的变体来备份我的数据。这些硬盘体积较大且需要外接电源，但它们是我用过最便宜且最可靠的硬盘之一。

Best for Portable Backups

最佳便携备份硬盘

If you travel a lot, you’ll want something that’s easier to carry than an Elements drive, which isn’t the best for lugging around in a suitcase. For backups when traveling, I love Western Digital’s My Passport series, especially the new Ultra version, which uses a standard USB-C cord, eliminating the need to carry a separate cable.

如果你经常出差，你会需要比 Elements 硬盘更易于携带的产品，毕竟后者并不适合塞在行李箱里到处跑。对于旅行时的备份，我非常喜欢西部数据 (Western Digital) 的 My Passport 系列，尤其是新款 Ultra 版本。它使用标准的 USB-C 线缆，省去了携带额外数据线的麻烦。

It’s not the thinnest drive on the market, but it’s less than an inch thick and solid enough that I never worry about tossing it in my bag. (Although it should be said that this is a spinning drive, so don’t literally toss it.) I also like that the corners are nicely rounded and there are no screws or anything else that will snag on fabric in your bag.

它虽然不是市面上最薄的硬盘，但厚度不到一英寸，且足够坚固，我从不担心把它扔进包里（尽管必须说明这是机械硬盘，所以不要真的用力扔）。我也很喜欢它圆润的边角设计，没有螺丝或其他会勾住包内织物的东西。

A More Rugged Spinning Drive

更坚固的机械硬盘

The SanDisk Professional G-Drive ArmorATD is a solid, semi-rugged external hard drive that doesn’t (currently) cost as much as some of the others in this class. This is the first drive in Western Digital’s new SanDisk Professional line, and, somewhat uniquely among drives, it comes with the macOS-friendly HFS+ drive format out of the box, making it plug and play with Apple’s Time Machine backup system.

SanDisk Professional G-Drive ArmorATD 是一款坚固的半三防外置硬盘，（目前）价格并不像同类产品中其他型号那么昂贵。这是西部数据旗下全新 SanDisk Professional 系列的首款硬盘，它在同类产品中比较独特的一点是，出厂即预装了对 macOS 友好的 HFS+ 格式，使其能够与苹果的“时间机器”(Time Machine) 备份系统即插即用。
