Back in November 2025, the 4TB Samsung 990 Pro I slotted into my most recent PC build set me back $318. Today, as I’m writing this, Amazon is asking $1,100 for the identical drive.
That single figure changes the entire conversation about whether the USB flash drive has run its course. A decent case could be made that it was fading. Then the storage market came apart at the seams.
The obsolescence rating nobody expected
Over at the Museum of Obsolete Media, USB flash drives are still scored a 1 — a low risk of obsolescence. The reasoning is decidedly unromantic: for as long as there are USB ports, there will be drives to slot into them.
No direct evidence exists that flash drive sales are on the slide. Preferences are what shifted. Files are bigger and hardware is quicker than it used to be, and anybody in IT or a creative profession has spent years grabbing something with more muscle.
Why they stopped feeling useful
It comes down to capacity. The ceiling for most brands sits at 128GB, a rounding error once you start shuffling modern files around.
Record 4K on a recent smartphone and high frame rates will eat roughly 1GB for every minute you shoot. A backup of your phone or PC, a bloated ZIP archive, an entire project folder — each one sails past what a thumb drive can hold without breaking a sweat. Even when the files do squeeze on, they inch across the bus slowly enough that you may as well go make a coffee.
There’s a solid rationale behind SSDs taking over the role. The best of them offer 1TB and up with vastly quicker transfers, portable models are tougher thanks to protective housings, and the memory controllers inside tend to be of higher quality. Everything else being equal, an SSD will comfortably outlive the average flash drive, which is what makes it the smarter purchase over time.
Nor is bulk the sticking point it once was. The latest portable SSDs really do fit in a pocket. They’re not thumb-drive tiny, but they vanish into a bag.
The port problem cuts both ways
USB-C is the only data port on some of the newer laptops. Flash drives with USB-C connectors are available, but the SSD route is less fussy because it relies on a cable — and most of the popular portable SSDs bundle both a USB Type-A and a Type-C cable, letting you grab whichever one your machine will actually accept.
That’s a genuine edge in convenience, and right up until recently it settled the debate.
Then the AI boom broke the price
Appetite for data center memory and storage has driven SSD prices through the roof since late 2025, while PC sales have dropped. Before that, prices had settled at rock-bottom levels that made hoarding data cheaper than it had ever been. The fresh wave of demand launched them into the stratosphere.
Which is how the 990 Pro travels from $318 to $1,100. Adding insult to injury, Samsung’s slower 990 is now more expensive than the original.
What $43 buys you now
By comparison, the flash drive listings on Amazon look positively serene. They haven’t escaped price rises, but the pace of those increases has trailed SSDs and HDDs, and modest capacities keep the cost per unit low.
As of this writing, a five-pack of PNY 64GB USB 3.0 flash drives goes for $43. Measured per gigabyte, that sits far, far beneath what the Samsung 990 commands.
Unless you’re churning out reams of 4K footage — and if your needs mostly amount to ferrying a handful of documents or stashing tax filings somewhere physical — the arithmetic has swung back the other way. Google Trends registers a massive spike in search interest from early 2026 onward for phrases such as “USB flash drive portable” and “USB flash drive 128GB.” Plenty of people are running these numbers for themselves.
The jobs an SSD is too expensive to do
Bootable media remains the flash drive’s turf. There’s no sense tying up a whole SSD to install a Linux distro or set up a Windows 11 instance, and at today’s prices that isn’t even a close call.
The same goes for zero-footprint portable operating systems such as Tail OS, or a keychain-sized kit of repair and diagnostic utilities. Or simply carrying storage on you for when it’s needed.
Get the five-pack. Load one with a Windows 11 installer, stick the others in a drawer, and take another look at SSD prices in six months.
