Kingston stick is USB 3.0. Theoretical speed of up to 5Gbits/second.
Toshiba stick is USB 2.0 Theoretical speed of 480mbits/ second.

Search is your friend (not necessarily Google).


Okay, thanks. Except I don't think the port is USB3.


usb 3 ports cant make a usb 2 device go any faster.


Seeing we are on the subject and I am about to buy 3 or 4 new sticks,
What are the preferred programs for bench marking read and write speeds?

My point exactly. In the context of the earlier comment, being USB3
cannot account for Kingston being faster than Toshiba unless the port
is USB3, which it isn't.

Why buy "new sticks" when you can buy portable hard disks for almost the
same price and more robust? Are you out of your mind old man?

Go and buy couple of 1TB portable hard disks from big brand names and
you are sorted for the rest of your life. at your age you don't have
much time left on this planet. Allah will take care of you. Ask Yousuf
Khan who is currently recruiting suicide bombers to help people like you
who wants to reach Allah quicker than the rest of us.

Not enough information.

What are the USB standards?

I don't know where to find this information.


Does your computer have USB3 jacks?
Are your two sticks usb 2 or 3?

USB 3 jacks and sticks have 9 pins. They are usually blue. Sometimes yellow.
USB 3.1 jacks are usually red.
USB 2 has 4 pins. They are usually black.
USB 1 is usually white.

Oh, you want peer analysis of UNIDENTIFIED brands and models of USB
flash memory. Uh huh.


I am glad you have recognised this is difference between brands, from
the limited information. I thought there might be other factors, such
as age or variability.

If it helps, the faster one is a Kingston Data Traveler 16GB. The
slower one is a Toshiba TransMemory 16GB. Any analysis appreciated.


Toshiba makes a "stable" of such sticks. Look for the part
number on the stick in tiny print.

https://www.bestbuy.com/site/toshiba...?skuId=3516967

# Model: PFU016B-1BLR $9

*******

These are USB2, and only the u202 lists specs for read/write.

https://pc.toshiba-asia.com/storage/...cification.php
https://pc.toshiba-asia.com/storage/...3/overview.php
https://pc.toshiba-asia.com/storage/...2/overview.php

Read: Up to 18MB/s , Write: Up to 5MB/s

They make USB3, but few have specs listed.

https://pc.toshiba-asia.com/storage/...cification.php

Read Speed Up to 120MB/s

When you're ashamed of your write speed... it shows.

https://pc.toshiba-asia.com/storage/...cification.php

Read Speed Up to 150MB/s

Still no write speed. I'll just assume it's 10MB/sec, for safety sake.

https://pc.toshiba-asia.com/storage/...cification.php

Read: Up to 70MB/s

https://pc.toshiba-asia.com/storage/...cification.php

Read/Write Speed*

16GB - Read: Up to 130MB/s
Write: Up to 25MB/s

Alright, a product that's come out of moms basement, to live on its own.

https://pc.toshiba-asia.com/storage/...I/overview.php

Read/Write Speed*

32GB - Read: Up to 222MB/s
Write: Up to 130MB/s

OK then, they're getting it now. So they make
one product worth owning in the USB3 camp.

*******

And "Kingston Data Traveler 16GB" probably spans a few
generations, and some of the early ones might not be
listed in the spec table today.

Picking something at random. DT100G316GB

(Turns out, I have one of these, and it just says
"G3" and "16GB" on the body. The connector color
on mine isn't right, so perhaps this isn't the same one.)

https://www.kingston.com/en/usb/pers...siness/dt100g3

No spec there.

https://www.newegg.com/Product/Produ...9SIA12K3742665

"DT100G3/16GB $8

Read Speed up to 100MB/s
Write Speed up to 10MB/s
"

So there we have it, yet another smoking example.

The sad part is, you can pay $20 for two entirely different
USB3 sticks, one with the stinky 10MB/sec write rate, and
the second one actually worth owning. The price is not
the sole factor of interest, if shopping at Staples, as
they'll pile good and bad sticks into their "$20 range".

Your job as a shopper, is to ferret out these details,
and say "no" to the lame/gimp ones. This is definitely
*not* an impulse buy item, due to the level of dishonesty
involved. Plan your strategy at home, then go shopping.

Kingston Data Traveler 16GB


A search on just that ended up with matches on:

DataTraveler SE9 USB Thumb drive 8-64GB
DataTraveler microDuo 3.0 USB
DataTraveler G4 USB flash drive 8GB-128GB

That's why I asked for a model. Still have the sales receipt? Did you
order this through an online account (Newegg, eBay, Amazon, Walmart,
etc) where the sales transaction has the details?

Toshiba TransMemory 16GB


A search on that turned up several hits; however, it became apparent
from most hits that this is likely USB 2.0 flash versus the Kingston
which is likely USB 3.0. There's your massive speed difference right
there - assuming you have a USB 3 port to use both drives instead of
using a USB 2 port which will throttle the USB 3 flash drive down to
USB 2 speed.

USB 2.0 - 480 Mbps ( 60 MBps)
USB 3.0 - 5 Gbps (640 MBps)

Those are the theoretical limits. You'll never achieve those,
especially if you hook more than one active device to the same USB
controller, but you get the point: you are comparing a USB 2 flash drive
to USB 3 flash drive.

Find the model numbers. Then go to the manufactures sites to get their
specifications (and realize they're pushing their specs).

All flash memory is self-destructive due to oxide stress in the
transistor junction: the more you write to it, the sooner it will
catastrophically fail. Until then, blocks that go bad get masked to
other blocks. The redirections for the masking cause lag in access
hence the memory gets slower. You've probably been using (writing to)
the USB 2 flash drive a lot longer than the USB 3 flash drive.

Context that you never before stipulated. How do you know it is only a
USB 2 port and not a USB 3 port?

Just because it is "flash memory" doesn't mean there is only one way to
construct that memory, just like "car tire" doesn't stipulate the
compound, tread pattern, or other characteristics. Without the model
numbers, there is no information regarding what the manufacturer claims
for read and write speeds. Besides their own proprietary designs, there
is also the basic constuction. We don't know if your flash drives are
SLC, MLC, or TLC. SLC is fastest with least density per die but the
most costly versus MLC with highest density but slowest and cheapest.
Consumers going only by price and capacity don't bother looking at
whether they are getting SLC or not because SLC is outside their price
range. They want high capacity at cheapest cost without regard to
speed. The problem with most retailers (online or physical store) is
that they do not divulge the cell layout of the flash memory - because
they don't know.

https://en.wikipedia.org/wiki/Multi-level_cell
https://en.wikipedia.org/wiki/Flash_...s_of_operation

SlC is lower density, faster, and more expensive. MLC and QLC are more
dense, slower, and cheaper.

Without knowing about cell design differences, consumers see a 16 GB USB
drive for $10 or another for $35. Which do they buy? The cheaper one,
of course. The cheapy uses MLC and is USB 2. The pricier one uses SLC
and is USB 3. Consumers are ignorant of the specs. They don't look.
Research takes time. They think all flash memory is constructed the
same and that's why they end up getting cheap and slow flash drives.

A slower device could be SLC or MLC. But it would also need
to have a lower capacity. A 32GB stick should be the TLC type,
which you don't really want (but don't have much choice). If
you could find a stick at 8GB or smaller, it might be made
from an older standard of flash. But of course on a place like
Ebay, all "rules" could go out the window, in the "rush to fraud".
With a few minutes work, you could probably dial down a 32GB
TLC chip so that it reads out as an 8GB product.

I don't know if it's been mentioned, but don't buy any
of the USB3 sticks with the *plastic* barrel. The plastic
part bends too much, and you can snap off a USB3 pin inside
the thing, due to the connector mis-alignment (failure to
capture properly).

No. Certain brands are more reliable than others but speed itself is
not a factor.

Many aspects, including USB 2.0 versus 3.0 have already been discussed
by others.

Basically, you only 'get' the read/write speed specifications of the
USB stick at the time you buy the device. That is, *if* this information
is listed on/in the packaging.

*After* the fact, it's nearly impossible to get these specs, unless
you happen to know the exact product *number* (not the product 'name').

I.e. a 'name' such as "Kingston DataTraveler G2" tells you next to
nothing about the read/write speed specs of the device which *you*
happen to have. For example, a device with that 'name' might be USB 2.0
or USB 3.0.

So if you want to have this information, get it when you buy a USB
stick and save it somewhere.

A few days ago I was inquiring about various Disk benchmarking programs,
I finally chose Crystal Diskmark 6.0, seems Fairly consistent so I will
use it for USB drives.
