Should you buy a new external hard drive after Prime Day?

An external hard drive isn’t just for the files that will no longer fit on your computer. You can use an external hard drive to offload large files that you’re not using, freeing up space on your computer or gaming console. You can also use it as a digital safe for important and confidential documents, as it might be risky to leave these files on your computer (or worse, on the cloud) due to the prevalence of hackers. Whatever purpose you think it will serve you, the remaining Prime Day external hard drive deals are your chance to enjoy nice savings on premium models or even to purchase several external hard drives at a time.

Even if your computer or gaming console’s storage isn’t at the limit yet, you should take advantage of what Prime Day discounts are left to buy an external hard drive. It’s hard to predict when your storage will reach full capacity, but if your devices’ storage is already full, then it’s even more of a no-brainer to snap up any remaining Prime Day external hard drive deals while you still can.

There will surely be more deals for external hard drives later this year, especially come Black Friday and Cyber Monday. However, you shouldn’t delay purchasing your new storage devices if you’re expecting bigger discounts. While there’s a possibility of a better deal in November or December, it’s not guaranteed that retailers will be offering larger price cuts than what you can enjoy right now. Additionally, if you buy now, you won’t be left waiting for months for your much-needed storage expansion.

How to choose an external hard drive

The top brands for external hard drives are Western Digital, SanDisk, Samsung, and Seagate, although there are several other good ones, too. You should take time to study the different models of external hard drives and the features that they provide, and also be sure to read reviews.

To start the process of choosing an external hard drive to buy in the wake of Prime Day, you’ll need to determine whether you’ll go wired or wireless. Wired external hard drives require a cable to connect the accessory to your computer, while wireless external hard drives are more mobile because you don’t need cables to use them. However, wireless transfer speeds will naturally be much slower, although some wireless HDDs will have the ability to transfer data in wired mode when you want it.

You might want to check out Digital Trends’ best external hard drives and best wireless external hard drives for a better idea of what these accessories offer and the brands and models that we recommend most highly for each type. If you’re planning to use it for a gaming console, however, then you should also take a look at our best external hard drives for the PS4 and best external hard drives for Xbox Series X to help you narrow down your search.

Perhaps the most important factor in choosing an external hard drive is its storage capacity. It will be a waste to buy a 10TB external hard drive if you’ll just be storing your console’s save data. On the other hand, you shouldn’t buy a 1TB external hard drive if you’re planning to store a huge collection of movies or games, as it will fill up quickly.

You should also consider whether the external hard drive will be permanently placed in one location or if you’ll be bringing it along wherever you go. A portable external HDD will require a durability-focused design that will protect the device from accidental damage. You should also check the external hard drive’s physical size. You wouldn’t want to be lugging around a huge brick if you need the extra storage to be available at all times — a pocket-sized SSD might even be a good idea.

What’s the Right Laptop for a Student on a $1,000 Budget?
The best college laptop isn't the one with the longest spec sheet. It's the one that fits your budget and the way you'll actually use it.
Dell XPS 14 Review: Sticker

Buying a laptop for college isn't a decision made in isolation. Tuition, textbooks, housing, meal plans, transportation, and course materials all compete for the same budget, leaving most families with one question before the semester begins: how much is enough to spend on a laptop without paying for features that may never get used?

Siri is about to hear everything you say, but Apple’s privacy approach has me cautiously on board
Apple's new Audio Intelligence features want to hear almost everything you say. A privacy document released alongside them explains why I am mostly okay with that.
Apple Watch Audio Intelligence features

Apple used its September 2026 launch event to enter a feature category it has mostly avoided until now: ambient listening. Siri Recap, Live Rewind, Music Recognition with Shazam, and Sound Recognition all landed on the Apple Watch Series 12 and Apple Watch Ultra 4. All four depend on the watch microphone picking up sound around you far more often than any previous Apple product has.

Siri Recap listens for conversations throughout your day and turns them into short AI summaries you can check later. Live Rewind is smaller in scope but arguably more useful day-to-day. It transcribes the last 15 seconds of whatever was just said with a double-press of the crown. This is perfect for catching a name, a book title, or directions you missed the first time. Music Recognition uses Shazam to identify songs playing nearby without you lifting a finger, much like Now Playing on Google's Pixel devices. Sound Recognition is a useful accessibility feature that listens for sirens, doorbells, and alarms to alert users who have a hearing impairment.

Can You Turn a Mini PC Into a Local AI Agent?

Not every AI task needs the scale of the cloud. An employee searching company documents, a retail kiosk answering product questions, or a digital sign reacting to customer behavior all need fast responses, but they don't necessarily need to send every prompt to a remote data center. Running those workloads locally reduces latency, keeps sensitive information closer to where it's generated, and can lower the ongoing cost of AI deployments. As a result, many organizations are moving toward hybrid AI architectures that handle routine requests on-device while reserving cloud models for tasks that genuinely need more processing power.
