For years we’ve been told that hard drives fail, tape must be refreshed, and flash memory slowly forgets. Then along comes a headline claiming scientists have invented a glass storage medium that could preserve data for 10,000 years. That sounds dramatic. It also sounds like marketing. So instead of repeating the headline, let’s walk through the actual questions that matter — the same questions that came up in conversation. Because if this technology is real, the implications are technical, economic, and philosophical all at once.

So What Is H-Testing for USB Drives, Really?

I’m at a wine tasting. The kind where nobody is actually tasting anything. Everyone’s holding a glass, nodding politely, and trying to look like they belong in the room.

I bump into a tech mogul. Big CEO energy. Knows markets, valuations, and boardrooms — not flash controllers.

Somewhere between the Pinot Noir and whatever someone insists is “very exclusive,” he says:

“We once had an issue with fake USB drives. Someone mentioned H-testing. What is that, exactly?”

This is where most explanations go sideways. People either oversell it like it’s some kind of security certification, or undersell it like it’s just a quick format.

Why Multi-Pass DoD Erase Schemes Don’t Translate to Flash Memory, Despite Being Widely Referenced

For a long time, secure erase meant one thing: overwrite the data. Then overwrite it again. And maybe again, just to be safe. That approach worked, it was measurable, and it aligned neatly with Department of Defense guidance written in the late 1990s.

This used to be true. It isn’t anymore. Let’s all stop pretending otherwise.

If you still think “MLC is required for reliability,” you’re using a 2015 rulebook in a 2026 storage world.

If you’ve been around flash storage long enough, you probably remember when choosing NAND felt like a moral decision. SLC was “the good stuff,” MLC was the responsible compromise, and TLC was the thing you avoided unless cost mattered more than sleep. For a long time, that thinking made sense.

But here’s the reality in 2026: the MLC vs TLC debate is mostly historical. Not because MLC disappeared overnight, and not because endurance stopped mattering—but because the way flash storage is engineered today has fundamentally changed what matters.

This article isn’t here to pretend MLC and TLC are identical. They aren’t. Instead, the goal is to explain why the “requirement” to choose MLC over TLC no longer applies the way it once did, and why TLC is now the accepted, proven norm in mass storage environments—including some of the most demanding systems on the planet.

In a world where everything can be edited, one courier carries the last device that refuses to change.

The Shop Vac USB Drive That Shows Up and Gets the Job Done

Let’s be honest: nobody gets excited about another plain black rectangle with a USB connector. But a miniature shop vac that happens to store your files? That gets picked up. That gets shown around. That earns a spot on the desk instead of vanishing into the junk drawer of forgotten swag. This design doesn’t whisper for attention—it rolls in like a little yellow machine with a job to do.

What an AI Server Really Looks Like When You Open the Lid

There’s a lot of noise right now about AI using “too much memory.” Prices are up. Supplies are tight. Everyone says demand is exploding. You’ve probably read that already.

But most of what’s written skips the most important part: what an AI computer physically looks like, and why it needs so much memory in the first place. Not in abstract charts or market forecasts, but in terms you can picture. Once you understand what one AI system actually consumes, the rest of the story stops sounding dramatic and starts sounding inevitable.

I ended up explaining this recently in a place that has nothing to do with data centers. I was at my kid’s school for a “parent day,” standing in a classroom, and a few students started asking about AI. Not chatbot questions. Real questions. What does the computer look like? Where does the data go? Why does everyone keep saying “memory” like it’s the whole game?

Why law firms still struggle with document security after files leave their hands

The Quiet Reality of Legal File Exchange

As part of modern investigations and discovery practice, law firms routinely request, receive, and distribute electronically stored information (ESI). That data may arrive through a FOIA request, medical records production, prior counsel files, subpoena duces tecum, Rule 34 discovery, or directly from a client. While cloud platforms dominate general business workflows, physical media remains deeply embedded in legal practice.

Sometimes your data doesn’t “get deleted” — you just lose the door used for reaching it.

Imagine you’ve rented a PO box for years. Important mail goes there. Contracts. Receipts. Records you don’t need every day, but absolutely rely on when they matter. You pay the fee. You follow the rules. Everything works as expected.

Then one day, the mail stops. Not because nothing was sent — but because the post office location quietly closed. No notice. No forwarding. No explanation. The box still exists somewhere, but you have no way to reach it. You don’t know if your mail was returned, destroyed, or is sitting untouched in a locked room.

Portable AI hardware is starting to look practical for small and mid-size businesses — but only if you understand what problem you’re trying to solve first.

If you run a small or medium-sized business and you’ve been paying attention to AI over the past year, you’ve probably noticed something new creeping into the conversation: portable AI accelerators that plug in over USB. They look like flash drives or dongles, but instead of storing data, they run AI workloads locally.

When One USB Drive Shows Up as Two: What’s Really Going On

CompactFlash is The “Original Gangster” of Portable Storage That Quietly Built the Foundation for Today’s Removable Media

Pull up a stool, grab whatever’s in the glass, and let’s talk about a piece of technology that doesn’t get nearly enough respect. Everyone thinks the USB flash drive is the hero of portable storage. That tiny plastic stick that lives on your keychain. The one you’ve lost twelve times. But the real origin story? That goes further back. Before USB was cool. Before laptops were thin. Before cameras shot video. The real OG of modern portable storage was CompactFlash.

CompactFlash showed up in 1994, which doesn’t sound that old until you remember what the tech world looked like in 1994. Dial-up modems. Beige towers. Laptops that felt like gym equipment. Storage was floppy disks, Zip drives, and spinning rust hard drives. Flash memory existed, but it was exotic. Expensive. Mostly for embedded systems and industrial gear. Then SanDisk rolled out CompactFlash and quietly changed the entire trajectory of removable storage.
