I don't understand - am I a bit dim?

I didnt even know usb c existed until I bought my new phone a month ago.

What don't you understand? If you have one piece of tech with USB-type C and everything else with standard USB, then having both options on this flash drive allows data transfer between your old tech and new tech, or the data held on it available to all formats at anytime.

USB 3.0 'My Ass' it says on Amazon High-speed USB 31 performance of up to 150 MB/s

I was thinking that this is a great deal seeing it has speeds upto 150MB/s. But couldn't find the read speed in the description and wondered why they are trying to hide it.

What a con, it is about 11MB/s as measured by a customer. Christmas would be over the time you finished copying 128GB worth of files to this flash drive.

Cheap as chips

This states 3.1 on the Amazon european sites so wonder why not on the UK site.

I suspect it has something to do with the fact it has a USB 3.1 USB-C connector but in reality it is likely to be a USB 3.0 controller internally. Or just a typo on Amazon UKs part I guess.

Honestly this is about the performance you should expect at this price point. If you want truly decent speed you should be looking at proper SSD USB Drives like the Corsair Flash Voyager GTX. These are expensive but do offer about 80% of the performance an internal SSD would because its using a SSD controller and flash memory.

People are focusing on the wrong thing with flash drives and micro SSD cards. Its more about the card/reader fullfilling your minimum requirement as a function (in this case moving files between normal USB and new type - c), the top speed issue is across the WHOLE industry of storage/flash drives and not just Sandisk and its your understanding of what the speeds represent and under what conditions they can be achieved that causes the confusion and uproar.

They clearly state those max speeds are under certain narrow, perfect conditions and 'you' are unlikely to achieve them. Its in the small print on the back of the packaging. Write speeds are only up to 15X USB 2.0 (4MB/s), the max speed would be 'read' only. Nothing is being hidden from you.

Micro SSDs have to be inserted in the item you are using it for to achieve the speeds they advertise, in a small reader (with no onboard controller) stuck in a USB port in a PC will not be the same as inside an HD video camera where they will act according to their spec or you simply could not record the data the camera was saving to the cards. All storage speed will be degraded by fragmentation of the storage and the data written to it/its size and type. A top end camera recording 8k at full size would need to write 100MB/s and the associated required micro SSD card handle this when IN the camera. Try writing your mp3 collection to it through a £10 card reader in your USB port and you won't get 100MB/s for a large variety of reasons.

That aside does your car do the speeds its claimed, does it give you the MPG you were told, probably not. This is not a new thing to expect on selling anything, marketing ploys and 'headline' figures are common place. The words 'up to' are used a lot! Up to x speed, up to 50% off, up to x miles on one charge/tank, up to x time before battery runs out from full charge etc. All conducted under X perfect conditions....

USB 3.0 has been renamed as USB 3.1 Gen 1 and is fast enough for anything but the extreme high end drives.
USB 3.1 Gen 2 has the double the throughput of Gen 1 but drives like this rated for 150MBs read speeds won't get close to requiring the extra bandwidth.

Sandisk don’t give a write speed which usually means it is very slow:
sandisk.co.uk/hom…e-c

Personally I’d buy a SanDisk Extreme Go 128GB and a small Type A to Type C adapter as it is rated for 200/150 MB/s Read/Write; which I managed to do for the same price as this.
But some people are allergic to adapters and aren’t fussed about slow write speeds.

thats not relevant in the slightest
if that was the thing here then the read and write speeds would both be at the max 'ideal'
the thing here is the memory chips involved are slow

Write speeds will never be the same as read. What is relevant is the manufacturer is not hiding anything, its in the small print what an item can and cannot do. How you interpret it or not is up to you. Any write performance advertised is on perfect equipment, in a labatory and sequential data on a fresh formatted drive and will be documented and legal. It may then result in advertising bluff but it still has to be backed up by the testing. The memory chip is not slow it can achieve those speeds, just not in real world 'personal computer environments', which is different to being just slow and would therefore be a lie in the advertising.

If you really wanted to move data quickly from one place to the next you would buy a full size SSD and put it in a dedicated data controller, small compact flash drive storage sizes have outgrown their limitations, they sell 2TB flash drives for goodness sake (you might take 24hrs to write to it), made them the size of thumbnails and sell them cheap, that cannot expect to get fast aswell. Originally they were perfect for moving small amounts of information quickly that were bigger than email capabilites and avoiding the effort of writing to DVDs/CDs, they are also good for writing data to be held on there and then dissemenated (read) by various end users/tech. In effect writing once and read many times. If you want to do something else you need to buy something that is designed specifically around that requirement or spend big to have your cake and eat it.

The requirement of this item was to provide dual support two USB standards in one 'compact' package, it did not advertise it would write quickly, so don't expect to get that.
Agharta above provides an alternative (Sandisk Exrtreme Go) thats advertised as fast write for a little more money however you have to have an adapter too, that you might lose, and its also nearly 2.5 times the volume - 7.1cm x 2.13cm x 1.11cm (16.79) vs this item at 3.8cm x 2cm x 0.9 cm (6.84)

So the Sandisk Extreme Go is fast but larger in volume of a factor of 2.5 (length being the main contributing factor) so they are apples and oranges - for this item to be 'compact', 'offer 2 standards' and 'fast'.....you will be paying way more than £32 or you simply cannot get an item this small and expect it to have the gubbins inside to be as fast as a larger item.
Don't forget to have the second adapter built into this item reduces the inside space even more than one with just one USB standard, so the internal useable space for circuit boards etc inside is actually probably 3 times or more the smaller by volume than available for circuit gubbins in the Extreme Go. So something has to give and write speeds are considered the fall guy in this case.

Like I said know a product and its limitations, then you won't be dissappointed.

People want their cake and eat it i'm afraid. Just like another poster you are correct in identifying a USB flash drive with 'write' speeds people want, however it comes in a package over twice the size of the compact ones (sometimes 3 times that of the internal space the circuit board has to operate in), but people can't appreciate size will compromise speed unless you pay big money, and the market for large capacity 'compact' drives is driven by price, so you can't get high 'write' speed in that equation too.

its not a question of learning - do you really think you have written anything 'difficult'?
its a question of relevance and context

Original Poster

you complained about the speed, you were given 'valid' reasons why you would not get this speed, you just don't care for them.

Bottom line is you can't have Small and Fast in a compact sized competitive market. You either have to compromise on speed of write (as read is more important of the 2) or price. In this case its write speed.

If you have a problem with the marketing, thats just the way it is, you look past the marketing to see what you will really get. Its the same with 1000s of items sold, headline figures written in a way to maximise selling ability. Marketing is here to stay whether you like it or not.

Sorry, I think I confused few people. I meant WRITE speed as being very slow around 11MB/s.

It does depend on how you use a USB drive as almost all PCs that support USB Type C also support Type A so a converter is not required.
For home usage I don't like drives that are too small as they don't sit in the hand so well and the saving in space is irrelevant for home usage to me.
But if you want portability and dual connectors above all then this is good drive.
