I have just done a speed test crystal Disk mark on Samsung Bar plus and shocked at the terribly results I bought them from eBay see the scores below.They have to be fake with scores like that They were in the packaging that looks like the real thing.The price was a giveaway at less than £20 for two 128gb i should have sussed that out with them being so cheap..I see one of them on amazon costs over £25.Have any of you been caught out buying getting fake flash drives or SD cards?The two Samsung bar plus 128gb705 704.709 a 32gb Samsung bar plus .a lot better score than the other two ,but fails to give scores for the last two write speed why? 713 32gb Sandisk which does all the test.Perhaps i should stick with Sandisk they seem to have more on there Sandisk 29.2 gb the 32gb Samsung 26,5.The two Bar plus 128gb 117gb.707 Packaging.

I bought them from eBay

So you never buy there again? Or?..

 

[bonehead123]

Now you know why alot of people call it "fleecebay".

Yes, I have sold a boatload of stuff there (as recently as last week), but it's been 12+ years since I last bought anything there, back when it was somewhat less infected with scumbags, scammers, and scalpers etc...

Just chalk it up to a "lessons learned" moment, and from now on, just stick to actual, legitimate etailers for all your tech stuff

Also, just an FYI, but your sentence structure/composition could use a little work.... I know ya'll talk a little different over there, but just sayin

Well i will be a bit carefull.I buy lots of stuff on there most of the time everything is fine.Does anyone have any clue as to why the drive below failed to give a score for the last two write lines?I kept on trying but still no scores on thoise last two lines.

Yes i have learnt my lesson ,I must admit it has only been recently i have been checkin SD cards and flash drives with H2testw.I tried it with one of the drives, but it took 4 or more hours to get a quarter of the way,i guess 128 gb is to much to test with it.Anyway they have been sent back now. I know i,m not that good at writing .

I use an Sandisk Extreme here as USB stick, very very fast. Almost double the one from Samsung you have.

 

[TheLostSwede]

A couple of years old model and test.

And their newest model with usb-c connection. Almost the speed of an ordinary SATA SSD!

Thats good but they are expensive. Heres the Sandisk Ultra flair 32gb which i dod get from eBay which beat the Samsung bar 64gb.

All marketplaces are prone to misrepresentation, including Amazon and Newegg. It's not like any of them verify the authenticity of products sold by 3rd party sellers. In fact Amazon kind of does the opposite, where it commingles inventory of the same product between sellers. Amazon itself has been the subject of numerous scams over the last few years.

I'd say let's actually verify if this item is a fake first before jumping to conclusions. In general you as a customer should always be checking if products you are purchasing are genuine anyways, regardless of your trust in a retailer. As the saying goes, trust but verify. That said because a product under-performs doesn't immediately make it a fake. Particularly in the computer and electronics word, there are many other factors that can result in lower than expected performance.

Speed test 128gb Bar Plus

First I'd check to ensure you have the drive attached to a USB 3.1 port. If you are plugging it into a USB 2.0 port or your computer's front panel USB you aren't going to get advertised speed. If your system has more than 1 USB 3.1 port, trying switching ports. Short of those solutions working, try it another another USB 3.1 capable system to see if performance is any better. You can also try reformatting to NTFS with default allocation size. I'd recommend trying at least one other testing tool (like Anvil) and try increasing the test size to something large than 1GB to see if it has any effect.

Last, you can find the drive's serial number with a program like HWInfo. You can contact Samsung with this information to verify if the product is legitimate or not.

A bell should rinkle when something is too cheap....Too good to be true...

Hope it doesn't happen again.

I've got 5, LOVE them. Got them from Dell with Dell Bucks

The best program to see what your device and USB ports are capable of is USB Device Tree Viewer. V3.8.9

Here in screenshot with an 970 EVO plus in USB3.2 Gen 2 connection external. It even shows that this external 970EVO NVMe needs 896mA to work.

Expensive? 35 dollar for 128GB USB 3.2 stick... By now in 2023 you should know already that you can't sit down on the first row for 1 cent. Filling up your car's gas tank costs more!

Bought 4x64GB Kingston microSD cards a couple of years ago that were fake. Besides low speed I wrote some software to write 1MB blocks filled with a 32-bit number and incremented each new block so I could write the entire disk and then verify contents. Found they only had about 110MB of usable storage even though they indicated 64GB and 64GB was written!

 

[SPDIF]

You can still buy USB sticks on Ebay from 1TB that actually has only 64Gb, when the first 64Gb is written full, the controller is programmed to save from the beginning again, effectively overwriting you previous 64GB of data! Make windows or linux believe there is still space left. It keeps track of file names, but the file itself is overwritten with other data.

I know you can get ones on eBay where they say they are 2tb etc when they are a lot smaller these come from China you have to be a mug to buy them.

2 dollers for 2tb

Welcome to Techpowerup:D:D
I like a lot of people on eBay just give feedback in how quick they recived the product etc , with out testing it first.I used to do that myself.Bur now i use the free tester H2W yo make sure they are what they say thej are.

See the video i just put on here all about that.

Use h2testw to see the drive's real capacity, but flash drives are something they counterfeit by the dumptruck, and they're cheap enough you should only buy them from reputable stores and avoid ebay in general

Thats what i use now h2testw great bit of software Of course you can get fake flash drives and Sd cards on Amazon as well.

 

[SPDIF]

h2testw is with bigger drives completely unusable, waiting times of sometimes one or two days. You must have a lot of patience testing scam drives. It's faster if you for example copy a big game on it, or other files and then try to read it back. You know the result in some minute, instead of hours or days for h2test! It's really good to test smaller capacity drives or memory cards.

Most games are now very big and copy the files to a scam drive doesn't end good. I can't afford the very big waiting time here, but do the test with big game files gives you the result in minutes.

I'd avoid Amazon too, because of their inventory commingling

Aa long as it's sold/shipped by Amazon (preferably with Prime) you should be fine. Just avoid used or open box listings
