Understanding the Difference Between Firmware Identity and Software Simulation

At some point, almost everyone working with USB media runs into the same question: Can I make a USB flash drive appear as a CD-ROM drive?

The question usually comes up when someone wants something to auto-launch, behave like a software installer, or function in a locked-down environment where USB behavior is restricted. Many assume this must be a Windows setting, a special file, or maybe a hidden configuration trick buried somewhere in Device Manager.

But here’s the key misunderstanding: this is not an operating system trick. It’s not a file trick. It’s not something you toggle in properties.

It’s a peripheral identity setting defined inside the USB device itself.

Micron just launched the first PCIe 6.0 SSD — the Micron 9650 — capable of sustained reads up to 28GB per second and write speeds over 14GB per second. That’s not incremental. That’s architectural.

On paper, it doubles the throughput of PCIe 5.0. Random reads reach into the multi-million IOPS range. For AI data centers feeding GPUs massive training datasets, this isn’t a marketing bullet point. It’s reduced idle time, tighter latency, and better utilization of extremely expensive silicon.

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.

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?

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.

USB vs Ethernet: Speed Is Easy — Reliability Is the Real Conversation

Every comparison between USB and Ethernet tends to start the same way. Someone pulls up a chart. Someone circles a number. Someone declares a winner.

And most of the time, USB wins that opening round.

Modern USB is fast — sometimes surprisingly fast. With a short, good-quality cable and a single device on the other end, USB can move data at speeds that traditional Ethernet links struggled to reach for years. That’s real, and it’s worth acknowledging up front.

But speed is the easy part of the discussion.

Speed is what you measure when everything is new, clean, short, and cooperative. Reliability is what you discover months later, after cables have been bent, ports have loosened, and users have interacted with the system in ways no spec sheet ever imagined.

That’s where the USB vs Ethernet conversation stops being about benchmarks and starts being about reality.

What USB Was Designed For — and What We Ask It to Do Today

USB was originally designed as a peripheral bus. One host. One device. Short distances. Tight timing. Predictable power delivery. Everything about the architecture assumes proximity and control.

When USB stays inside those assumptions, it performs extremely well.

The problem is that modern USB has drifted far beyond its original job description.

Today, a single USB cable is expected to move high-speed data, deliver meaningful power, negotiate voltage and current, identify itself, sometimes authenticate capabilities, and do all of this through a connector small enough to fit in a phone. In the case of USB-C, the cable itself may even contain active electronics.

That’s not a flaw — it’s an evolution. But it’s also a stress test.

The protocol grew faster than the physical layer supporting it, and that gap shows up not in lab tests, but in support tickets.

Five Reasons USB Sticks Will Be Around a Dozen More Years — and Why Flash Drives Still Matter in a Cloud-First World

Reason #1. Universal Compatibility Isn’t Going Anywhere

If you’ve been around USB as long as we have at GetUSB.info—since 2004, back when flip phones ruled the earth and “cloud” meant weather—you start to notice a pattern: every few years someone confidently announces the death of the USB flash drive. And yet, like a reliable old fishing boat or the one screwdriver you can never find until you really need it, the humble USB stick keeps showing up exactly where it matters. The first reason is simple: universal compatibility isn’t going anywhere. USB ports remain the one port manufacturers can’t ditch without getting angry calls from people who still plug in everything from cameras to car infotainment systems to conference room displays. As long as hardware continues to lean on USB-A and USB-C—and trust us, it will—flash drives stay relevant by default.

Reason #2. Air-Gapped Security Still Beats the Cloud

The second reason is the big one nobody wants to admit: air-gapped security still beats every “modern” idea floating around. Cloud storage may be convenient, but it’s also a giant target with a blinking neon sign that says “please hack me.” A write-protected USB drive — yes, the same kind used in clinics, labs, field teams, military gear, and everywhere else with real stakes—remains the easiest way to guarantee nothing gets added, deleted, or tampered with. When HIPAA folks and compliance officers clutch their drives like priceless relics, they’re not being dramatic. They’re being smart.

Reason #3.

USB 5Gbps — The “Hold My Beer, I’m Fast Enough” Speed

Look, if USB had a middle child, this would be it. Five gigabits per second sounds impressive until you realize it’s basically the cousin who runs a 5K once a year and brags about it all Christmas. It works. It transfers your files. It doesn’t complain. And when you plug something in, chances are it’ll say, “Yeah man, I got this,” even though you know it’s secretly wheezing on the inside.

This is the speed tier where hard drives feel comfortable, basic flash drives don’t embarrass themselves too badly, and you can still pretend your aging laptop is “totally fine.” Sure, 5Gbps is cute. But once you see the numbers above it, you’ll wonder how you ever lived like this.

Gbps — Gigabits per second — is just a fancy way of saying how fast your data is hauling down the wire, and honestly, the name sounds way more complicated than it is. A gigabit is just a billion tiny digital dots, bits, the little on/off blips everything in tech is built from. Stack a billion of them together and shove them through a cable every second and boom, you’ve got 1 Gbps. The trick — and this is where people get tripped up after a couple beers — is remembering that a bit is not a byte. There are eight bits in one byte, so whatever Gbps number the marketing guys slap on the box, you divide by eight to get something that actually makes sense in the real world, like megabytes per second. So that “5 Gbps” USB port? It tops out around 625 MB/s if everything’s behaving, the planets align, and you haven’t kinked the cable behind your desk. Call it what you want, but Gbps just means “how fast this thing can move stuff,” and that’s all anyone really needs to know before pouring another drink and pretending USB naming isn’t a complete disaster.

USB 10Gbps — The “Feeling Pretty Good, Might Transfer a Movie Later” Tier

Ten gigabits is where USB finally puts on a clean shirt and acts like it has its life together. Suddenly everything feels quick. Your transfers stop dragging. Your external SSDs stop sounding like a clogged sink. You start believing in technology again.

This is the speed that makes you feel like you’re living in the future without actually needing to understand anything. It’s double the speed but also double the confidence. It’s the “I’m not rich, but I’m not eating gas station burritos anymore” of USB performance.

USB-C is a big step forward for connectors, but it is still a confusing mess when it comes to what each port can actually do.

I just spent the afternoon reading the USB-IF documentation about USB-C and I have questions. And rants. While I was at it, I revisited our breakdown of USB Power Delivery here: USB-PD Explained with Charts .

USB-C is supposed to be the great universal port of our time. One cable to rule them all. One port to simplify everything. One connector so symmetrical you can plug it in upside down at 2AM and still feel like a genius.

And honestly, it is a huge improvement. It is the direction the industry should go. Finally, a connector that is not designed by the same person who thought micro-USB was a good idea.

How Many USB Flash Drive PCBs Could You Make From the Monumental Nugget of 1869?

If you crack open a USB flash drive hoping to find treasure, you’ll be disappointed—but not entirely wrong. There is gold in there. Not much, not enough to make you rich, and certainly not worth firing up a smelter in your garage. But a typical USB PCB does contain tiny amounts of gold in its connector plating and, in some cases, inside microscopic bond wires. How tiny? Most USB boards carry somewhere around 1–5 milligrams of gold—less than what sticks to your fingers after eating a Dorito.

Manufacturers use gold because it’s solder-friendly, corrosion-resistant, and makes a perfect electrical contact. Even the thinnest “gold flash” layer on connector pins can survive years of plugging and unplugging. But for recycling? Forget it. You’d need thousands of dead USB drives just to make a visible speck of gold, and tens of thousands to produce anything resembling a nugget. Still, this tiny bit of gold creates a fun thought experiment: what if we went all the way in the opposite direction? What if we took one of the largest gold nuggets ever found and asked how many USB sticks we could make from it?

That brings us to the legendary Monumental Nugget of 1869, the crown jewel of the California Gold Rush’s late years.
