Western Digital launches world’s largest SATA drive with 3TB Caviar Green

By Molly McHugh Published November 16, 2011

The world’s largest SATA hard drive is now available from Western Digital. On Tuesday, the company announced both 2.5TB and 3TB versions of its Caviar Green drives.

The newest members of the WD family offers 3 or 2.5 terabytes of storage while minimizing the issues PCs tend to have with larger drives – namely, known driver issues with drives over 2.19TB. Both drives use an Advanced Host Controller Interface-compliant Host Bus Adapter to skirt compatibility potential issues with different operating systems.

Although they’re designed for 64-bit systems, they’ll also function with legacy 32-bit systems running Vista or Windows 7, with a few caveats. Western Digital offers a chart spelling out which operating systems will function with the drives and possible limitations. You can’t use them at all in Windows XP, for instance, and such a large drive won’t work as a boot drive in the 32-bit versions of Windows Vista and Windows 7.

To get an idea of approximately how much storage you’re looking at, the 3TB hard drive offers upwards of half a million photo and MP3 files, as well as 360 hours of high-definition video.

Like the rest of the Caviar Green line, the larger drives utilize WD GreenPower Technology to reduce noise and temperature.

The 3TB and 2.5TB external hard drives are available immediately for the competitive prices of $189.99 and $239.00, respectively.

From Handhelds to Monitors, these were the biggest glow-ups at Computex 2026

I walked into Taipei expecting spec bumps and walked away convinced four entire categories had levelled up.

Biggest Glowups at Computex 2026

Every year, Computex promises the next big thing. Sometimes that means another processor with a few extra cores, a laptop that's 200 grams lighter, or a monitor that's somehow even faster than the one before it. But every now and then, a trade show surprises you not with a single product, but with an entire category that suddenly feels new again. That's exactly how Computex 2026 felt to me.

After spending days walking the show floor, trying products, talking to engineers, and inevitably getting lost between booths more times than I'd like to admit, one thing became crystal clear. The biggest stories weren't about incremental upgrades. They were about categories, finally shedding old compromises. Monitors became smarter, handhelds became more mature, creator laptops became more versatile, and ARM processors started looking like genuine powerhouses instead of niche alternatives.

Apple Intelligence 2.0: What the New AI Features Actually Mean

The new Apple Intelligence features point to one goal: fewer app-hops, fewer tiny chores, and a Siri that finally earns the spotlight.

Light, Lighting, Flare

“Apple Intelligence 2.0” isn’t Apple’s official name, but it’s a useful shorthand for where the company is going. Apple calls it the next generation of Apple Intelligence, with Siri AI as the most visible piece.

That’s a risky place to put the spotlight because Siri has baggage. For years, it's been the assistant people use for timers, weather, and arguments with a glowing orb that somehow heard every word except the important one.

I saw Nvidia RTX Spark in action, and Windows PCs may finally have their Apple Silicon Moment

Nvidia RTX Spark could kick start a new Windows PC era

NVIDIA RTX Spark Chipset Computex 2026

Windows laptops have been chasing the gold that Apple struck years ago with its M-series chips. Back in 2020, Apple revealed a new lineup of MacBooks powered by silicon that seemed generations ahead in efficiency, integration, and even performance. It was a system that was built around the hardware instead of merely running on top of it.

At Computex 2026, Nvidia RTX Spark looked like one of the most convincing responses that Windows has had in years. I got a tour of Nvidia’s showcase at the show, and Spark was easily one of the most interesting things I saw. During the demo, the company gave me a close-up look at the RTX Spark as it ran video edits, local AI agents, games, and other hefty workflows. And in each of these tests, it became apparent that this isn't just another laptop chip reveal.
