Dear sifus,

today just bought Kingston DataTraveler Exodia pen drive...and it seems that the max transfer speed I can achieve is only around 8MB/s... but when i try on my old USB3 external hdd, they seem to be way much faster.
Any idea why this is like this?

I bought from a reputable PC shop so i believe this should be original and not fake...

how big is the files. mcm fake usb...

do a speedtest write n read and storage check for capacity

you make me want to try my old sandisk USB drive

this usb drive i test, buy more that 5 years ago

more than 20GB...

did you use usb 2.0 port or usb 3.0/3.2?

on top of that, u might wanna do diskmark etc for ur drive

so big... try smaller files 1GB see see..the speed got different... is no different might be fake oem copyright pasar malam quality kingston.

i try a 6GB file single file, when start 25MB/s
after about 2 min

Are you transferring those files from a HDD or ssd or nvme? If it’s from hdd then it will be slow. Usually about 10-15mb/s depending ot on why type of hdd ure using.

3. whatever just interface speed, but write speed depends on Nan chip, and probably you buy cheap.

Get NVMe for performance.

usb3.0 port

transfer from my c: which is nvme...

but ur usb port is?

here's a review of it

there has been some /r indicating significantly slower sustained speed via 2.0 port but i couldnt find the post

so thats why im asking

Is ur antivirus scanning the usb while ure transferring ? Perhaps that is slowing things down.

I’m not sure but looking at ur pic, it is 32GB. If is formatted to fat32 or ntfs? Can try ntfs if it’s not

First of all, get info on the read and write speed of your thumb drive.
If you are copying from HDD to usb, your write speed might be the limiting factor...

Cheap USB drive, slow speeds

It's expected

USB Drives get the lowest bin crappy QLC NAND because you're expected to use them just to casually store small files

All the good stuff goes into SSD

Manufacturers don't even want to say how fast their USB drives go on their site (spoiler: it's because they're slow)

If you want speeds, get a SanDisk drive which runs SUPER HOT but fast
Or Samsung Bar Plus for speed and not too hot

Kingston, Kioxia and other brands are quite slow

Or, diy pendrive with an M.2 SSD in an enclosure for the ultimate speed but at a premium cost

EDIT: That blog linked by sadukarzz is a good blog, I also read it
As you can see, they also got similar speeds, so it's just how the USB drive is designed, it's a cheap slow drive

I guess I got conned by Kingston marketing....and i am also not that knowledgeable here... I thought as long as it says USB3.2 interface then it should be as fast as USB3 should.... lesson learn... it cost me RM85 and I checked at shopee...some other USB3 pen drive for 256GB also around there or slightly more expensive so I thought it's market price also there about...

brought online? becareful.. alots is fake. but price rm85 for 32gb a bit pricey. some selling cheap is pasar malam quality copy right design alike orignal kingston. but the actual capacity is small n read/speed is low.

else get from OS store sure is original

I buy from a very reputable PC shop...i'm 99% sure they don't sell fake...

looks like this Kingston pen drive is meant to be slow and not fast... it just say USB3.2 interface but never really provide the actual write/read speed...

it says Gen USB3.2 compliance only.....it's a good lesson learn for me...

thank you

Plug in your usb drive.
Use the program usb tree viewer to check the connection interface. See if it is superspeed or highspeed.

file transfer also depends on type of files and windows activity in background read/writes on files on the disk.

10 files of 10GB transfer is way faster than 100,000 files of 10GB.

for executables may go through background viral scanning.

Pendrives sometimes performs very bad when they are 99% full.

For giga big files dont use pendrive.. use external HDD/SSD. Pendrives concurrent read/write is bad.. doesnt matter even with usb 3 bandwidth.

as for fake USB drives they are actually 16GB drives .. so try writing above 16GB will cause files corruption.

see users review.... seem like same problems.... even is reputable mall seller.... i guess the genie of the pendrive still untrustable

USB 3.0 bandwidth does not really translate to "speed". Just like driving your kancil in F1 track doesnt make the kancil any faster. The bus is a speed limit, just like PCIE spec.

USB Bus transfer speed only matters if it doesn't bottleneck the real performance of the disk it self.. in general USB sticks are really bad for concurrent read/write.. it cant even saturate 2.0 bus how can it make use of 3.0?. Try to simultaneously create multiple task of reading and writing.. and see its performance go turtles..

An example would be an external HDD with USB 2.0 BUS will be faster than general pen drive on 3.0 bus .. in a multiple concurrent read/write.

If you file is small but alot it will slow down

I would suggest you to try on another computer to test it out. You can send to Convergent @ AMODA 7th floor located opposite KL Times Square as they are a Kingston official authorized distributor in Malaysia, to check whether the drive is genuine or not, also and you can send it back to them for warranty claim if you think there is something wrong with the drive.

USB,3.0 flash drive used slower chips.

U better off using a real NVME drive plus M.2 NVME to USB adapter instead.

I'm using the Ugreen brand and can easily hit 300MB/sec when transferring from internal to external drive.

maybe the PCB for the pendrive rosak2?

nah... it's cheap and i should have known cheap = sus....

it says USB3.0 interface enable but never say it will perform at USB3.0 speed... i have come to accept it and i am using it to load media file on my TV and so far it is smooth so i guess the slow speed is also good enough for me to watch media files smoothly, even those big 20GB file.... so for now i'm good... thanks!

to those suggesting fake/faulty drive

its not, its genuinely how slow modern day cheap usb drives are
notice how they dont advertise speeds on their site, just say oh USB3.2 interface

I got one of these drives as well

I bought 2 of these Kingston thumbdrive but 64GB size version for about RM 20 each. The speed is indeed around 100 MB/s read and write is around 10 MB/s. As far as I can tell, it is genuine and managed to write 64GB video files into it and retrieve the videos back.

yeah, kingston did pull a fast one on this, but I expected these thumbdrives to be slow due to the price.

I'm afraid of buying Sandisk product already... 2 of their microSD card corrupted and i loss all the files
Another 64GB pendrive Sandisk representatives gave me as a gift for properly guessing their NAND design at a trade show also died after 1 use.


I got conned also. Bought the 256 GB Exodia for ~RM 75 to replace the dead Sandisk (read above).
And it's slooowwww. didn't even reach 10MB/s.

also bought from reputable store which i've bought several HDDs from in the past.

I just bought one with 256GB capacity, RM85, and believe me, it sucks to the max, transferring big files larger than 40GB took forever.
I have make another purchase of Sandisk Extreme Go 256GB RM226, and I think this time it won't goes wrong.

256GB shouldn't be RM85, at least wont be that soon.
real deal USB3+ pinout have 9 contacts, cheap ass USB2, or charging cable only have 4 pins


sauce https://en.wikipedia.org/wiki/USB_3.0

just know got such thing
i just use camera to zoom in to my sandisk, really got extra pin

This is original. Or you can find in Kingston mall but they usually out of stock for 32gb for USB3.2

So far my experience with Mono Digital is good.

I think generally if you're looking for good or high performance thumb drive, it should be more expensive one or big in dimensions, because extra circuit for dram or dual nand chips.

Tiny one you can forget about it, the advertised USB3. 2 gen 1 or 2 is very gimmicky for non savvy person.
It's just bigger bandwidth but not about the transfer rate
