Why are these USB flash priced so-o-o far apart?

[Alex Ethridge]

Why is one of these priced about three times as much as the other?

I see a difference in specs; but. with as little as I know about this stuff, I can't see that much difference.

Big difference in Read & Write speed ...
Most have very slow Write Speeds ... Write speed not specified in the Samsung ????
The Sandisc is equivalent to a USB external enclosure with a SSD.

I use a USB external with a SSD for transferring video files between computers ...
and working on the videos in the external.
This work would take way too long in a normal (Slow) USB flash.
The Sandisc would be nice if it didn’t cost about 4x the price of an equivalent size SSD for my external enclosure.

I didn't know that two USB 3.1 storage devices could be so far apart in speed. I assumed that since both were USB 3.1, they would be at least close in read-write speeds.

Also .... Read speed is no indication of Write speed.
Beware if both not specified.

You might have figured this out, (Like I did ) ...
If you Frequently Read/Write huge HD video files to/from flash.
(I can feel the need for Speed )

Digital Still cameras also function faster with a good mem card ... (Write speed)
I just ordered one of these ...
In a couple days, I'll know how it it improves my Point and Shoot camera.

I recently got this tablet and am looking for a connect-when-needed external storage. I'm looking for an affordable pocketable solution with as much speed as I can pack in at reasonable cost.

Yes, I've been using sites like this to help me select SD cards for my cameras for about the last three years.

I got two of these for my Lumix DC-GH5 camera. Speed mattered very much in it.

I got two Sandisk High Endurance cards for my dash cams. Speed wasn't as important as endurance on those.

And from my past experiences and research, when a seller leaves out an important specification (like write speed in this case), they are likely up to something sinister.

You've got some interesting info above

For the cost considerations .. I'd suggest a SSD (Laptop) Enclosure with a SSD.
I have an older version enclosure for my old SSDs.

I've been worried about SSD TWB endurance ... (because I was using a SSD in XP without trim)
I have have started moving to a Samsung 260 for the OS in my W7 computers ...
Because they advertised TBW Endurance improvements .

But the endurance TBW specs are hard to find .. or not specified.
I've been wondering about this HP
