This external SSD holds my Steam library, and it’s half-off for Prime Day

I jump around PCs a lot, so I’m not thrilled when I have to wait hours to re-download all the games in my Steam library that I want to play. Instead, I use external hard drives: a 1TB Samsung T7 and a 2TB SanDisk Extreme Portable SSD, and the latter is on sale for nearly half off during Prime Day this year.

The SanDisk Extreme Portable is an external SSD that I use to transfer my Steam library between PCs. The 2TB model I use has a list price of $460, but it usually sells for less than that — between $300 and $350 over the past year. During Prime Day, though, it’s selling for much less: Buy Now .

SanDisk has four capacities available, but I’d recommend the 1TB or 2TB model because they both have around a 50% discount. The 4TB and 500GB models aren’t as good of a deal with only about a 30% discount. The 1TB or 2TB size should be plenty for your Steam library, too. It’s certainly enough for mine.

I don’t have every game in my Steam library installed, but the SanDisk Extreme Portable SSD holds everything that matters. It’s dead simple to transfer an external SSD between PCs, too. Just head into your Steam settings, select Downloads, and select the drive as a Steam library folder. All of your games will pop in right away.

You can find other external hard drives on Prime Day for less, but you really want an external SSD for gaming — and the SanDisk Extreme Portable is among the best external hard drives you can buy. The one I use has speeds of up to 1,050 MB/s over a USB-C connection, which is more than enough for games.

If you’re a speed chaser, the 2TB SanDisk Extreme Pro is on sale, as well. This model is $280 with a 45% discount, and it goes up to speeds of 2,000 MB/s. You don’t need that much for most games, but if you want to kill loading screens, that’s an option as well.

Outside of the speed, the SanDisk Extreme Portable is a great travel SSD. It has IP55 dust and water resistance, and it can take a drop of up to 6 feet. It’s not quite as protcted as the Samsung T7 Shield, but it has enough protection to keep your Steam library safe while you’re traveling. And if you have some extra space where you want to store your files, you can encrypt it with AES-256 behind a password.

I mainly use the SanDisk Extreme Portable to transfer games between my desktop and my laptop, but you can use it elsewhere, too. It works with the PlayStation 5 through the USB-C connection, for example, and I’m interested in throwing some Velcro on the back so I can mount it to the Steam Deck.

OpenAI is locking its most advanced AI models offline after a string of security scares
OpenAI’s fake internet is a safety fix and an admission.

Part of me is relieved that an AI lab is hitting the brakes. The other part wishes it hadn’t taken real incidents to get there.

OpenAI said Friday that its most advanced models will now train without live internet access. Instead, they’ll practice on a cached, simulated copy of the web.

Your Windows touchpad is about to make scrolling long pages way less tiring
Three touchpad tricks that make long documents feel a lot shorter.
Windows new scrolling feature

Today I learned about a touchpad tip that I think every Windows laptop user should know. Microsoft shared it as its Friday Windows tip of the day, and it’s all about scrolling.

If you read long documents, browse webpages, or write code on a Windows laptop, you know the drill. You swipe, lift your fingers, and swipe again until you reach the part you need. Microsoft has three touchpad features that cut down on all that swiping.

This app turns the iPhone Duo into a pocket-sized Mac
Headroom uses macOS's built-in Screen Sharing to let users control their Mac from the foldable iPhone, without installing additional software on the computer.
Headroom App on Apple iPhone Duo controlling a Mac

The iPhone Duo has barely been out for a day, and someone's already found a way to run their Mac on it. Well, sort of. Headroom, a remote desktop app from MusicFlow, lets users control their Mac from Apple's new foldable phone, with an interface that adapts as the device opens, closes, and folds in half. Think of it as turning a pocket-sized phone into a miniature MacBook, minus the actual MacBook.
