Let me start by saying this: if you're serious about data security, the Apricorn Aegis Secure Key 3.0 is worth every penny. I've been using the 240GB version for months now, and it's completely changed how I handle sensitive files.

The first thing you'll notice is how rugged this thing feels. The aluminum casing gives it a premium, almost indestructible vibe - perfect for someone like me who's constantly on the move. The protective sleeve is a nice touch too, keeping those crucial number buttons safe in my bag.

What really sets this apart? The hardware-based encryption. No software to install (hallelujah!), just punch in your PIN directly on the drive itself. I use both Mac and Windows machines daily, and it works flawlessly on both - a lifesaver when IT has locked down my work laptop from installing anything.

The setup was surprisingly simple. Within minutes I had my admin PIN configured (you can set separate admin/user modes) and was transferring files. The LED indicators are super helpful - green means go, red means stop, no guesswork needed.

A few quirks though: this baby runs HOT during heavy transfers. Not melt-your-desk hot, but noticeably warm to touch. Also, while the metal case looks sleek, it does make the drive slightly bulkier than your average USB stick.

The brute-force protection gives me peace of mind - after too many wrong attempts (configurable from 2-10), it'll wipe itself clean. Perfect for when I'm traveling through sketchy airports or working in coffee shops.

Speed-wise? For encrypted storage, it's impressive. Large file transfers are noticeably faster than older encrypted drives I've used, though not quite as quick as unencrypted USBs (which defeats the whole purpose anyway).

Bottom line: If you're handling sensitive client data, personal financial info, or just want military-grade security for your cat memes collection (no judgment), this is hands-down the most reliable encrypted USB I've ever used. Yes, it's pricey - but compared to the cost of a data breach? Absolute bargain.
