500GB USB flash drive

We have noticed that many people found this blog by searching for 500GB USB flash drives. We wish to point out once and for all that there is no such thing.

There never has been, is not now, and never will be a USB flash drive of 500GB capacity.

The capacity sizes for different types of memory come in different units – hard drives come in units like 30GB, 40GB, 50GB, 60GB, 80GB, 120GB, 160GB 240GB 360GB, 500GB etc. USB flash drives do not!! If you see a USB flash drive advertised as these sorts of capacity then you can be sure you have spotted a fake.

The unit sizes for genuine USB flash drives go like this: 64mb, 128mb, 256mb, 512mb, 1GB, 2GB, 4GB, 16GB, 32GB, 64GB – do you see the pattern? So (if and when) a genuine flash drive of around the 500GB mark comes onto the market what size will it be? Why 512GB of course! However, we think that this sort of capacity may be some way off for technical reasons.

If you bought a flash drive advertised as something outside the pattern of capacities we have indicated then we can tell you (without any doubt) that it is fake. There are no genuine USB flash drives above 64GB at present – and most sold as 16GB or over are fake capacity. We strongly advise people not to buy flash drives until they have fully reseached the subject!! You can learn a lot about what is really available by looking at the websites of companies like Kingston.

Before you buy flash drives, ask yourself this question: – “Do I really need a massive capacity?” We’d say the answer is “Probably not.”

Since this post was written the capacity of genuine USB flash drives has gone up – there is now now one USB flash drive from Kingston available in 128GB capacity and one in 256GB capacity.

Please note – there are external hard drives of 500GB which connect to a USB port – but they are not the same as flash drives – you’d look a bit silly with a 500GB external hard drive dangling from your keyring – and we don’t think you could put it in your trouser pocket – unless you have unusually large pockets!

What we are talking about here is little USB flash drives (usually no more than 65mm long, 15mm deep and 20mm wide at most) that can go in a purse, pocket etc. very easily – not hard disks, which are larger.

  1. To Chase Tinsley,

    The largest “real” microvault is 64GB. Have a look at the Sony Microvault Global Website.

    Also you are not correct in your statement about no product being available in the USA with more than 128GB of storage. Check out the Kingston DataTraveler HyperX 3.0 – which is available as a 256GB Drive.

    You did not mention how you tested the drive – using typical peformance numbers for flash memory on a USB 2 system – a proper test would take 30+ hours.

    You have purchased a fake.

  2. Yeah yeah, we believe you (not).

  3. Sorry, but any of the “Sony” Microvault 500gb flash drive may look fake, but they are real. I bought two and have used (/tested) them completely.

    Yes, they do exist, and they work under the exFAT file system, which is patended by Microsoft so that is why there is no product available in the US above 128gb. Sorry, but it’s true.

    In your post you indicate the drives you purchase have two issues, slow write times and cannot format, Does not the issue that you cannot format the drives make you think that there is something wrong with the drives? Also, the two issues you mention are some of the telltale signs of a fake flash drive.

    If you still think the drives you have are real, then I suggest you do a google search on “fake 500 GB USB Flash drives” and look at the results. You should not be surprised by the results, unless you are a seller of fake flash drives.

    If you still think your 500GB USB drives are real then test with H2testw.

  5. Well we hope you won’t be disappointed when they trash everything, which they will. It ‘aint theory, it’s fact. Unless of course you are talking about hard drives that use solid state flash memory rather than USB flash drives of the type that go on a keyring etc.? 500 GB solid state drives that use flash technology do exist, but those are not what we are talking about here. Or are you one of those who peddle these fakes?

  6. I bought five of these 500 GB flash drives from China, one was faulty and the remaining four were working well. I repeatedly put in huge amount of music and videos and removed them, no problem whatsoever. The only thing is I cannot re-format them and they are kind of slow (about 20% of my 16 GB Cruzer drive). The theory of 500 GB do not exist is bull !

  7. No, usep, We have looked at the product picture, it is fake Sony, just ask Sony themselves. In fact, come to think of it I should report the site to Sony as they can probably get it taken down.

  9. Me too got a 500GB USB flash drive from China (branded as HP-USB) and it is working fine.

  10. In Yahoo Auctions Japan, there are people selling 1.9 TB flash drives for amazingly crazy prices (around 300 USD). They all mention about exFAT as a file system.

    Anyone knowing why the OS recognizes them as 2TB flash drives? What is the real size of those?

  11. The highest current capacity of flash drive available is 256GB – the next one will be 512GB not 500GB if you do the maths!


    May 11, 2010 at 7:17 AM

  12. let’s do a little math. assuming the producer can double flash disk capacity in 6 months. most flash disk are 1-16GB, with 2-4GB the most common capacity (and already cheap). say we start from this 4GB size, it may take 4 years to achieve this 500GB capacity. or maybe 2 years at most? we’ll see.

  15. Hi anex,
    We think we can tell you what will happen – you will not be able to view the whole of your movies because the files will be corrupted. It may look as though they are saved and, yes some of it will have been – up to whatever real capacity the drive has. Until you have exceeded the real capacity (which it seems you probably have) you can open files normally – after that you can kiss goodbye to all, or almost all (depending the on real capacity and what you tried to put on the drive) of what you seemed to have saved to it.

    We can guarentee that if you bought a flash drive advertised as 500GB it will corrupt your files after a while!

  16. i have one and have 16gb movies on it so far. i dont know what will happen in the future. i bought it for $20. one thing i notice is, it only work with vista , i tried it on my xp laptop it wont recognize it.


    April 6, 2010 at 8:51 PM

  17. Julio,

    If you did buy one it would corrupt your files! That is the whole point of this blog – warning people about fakes that trash your files.


    January 1, 2010 at 3:31 PM

  18. where did you got it?, so i can get one, please let me know.


    January 1, 2010 at 3:17 PM

  19. Just got in from a 14day vacation at China. One of the only things electronic bought was USB 2.0 SONY(know is not), 500g (as advertised) micro vault. With the form of a flash drive (8gb) I already have. Tried it in my Mac Pro, IBM, HP and properties indicate a 536Gb memory. I will be trying over the week end, but already archived and tested 8gb 0g photo and video, which was capable of accessing. Sunday or earlier will provide final test (500gb of data at 10gb segments)

    BTW, bought it for US $20 lowering from $100.

  20. Hey rocoso,

    Are you saying there is such a thing as a 500 USB flash drive? Or have you misunderstood what we meant?

    There is such a thing as a portable 500GB hard drive you can connect to a computer with a USB cable – but that is not what we are talking about when we say USB flash drive.

    What we mean here is a little thing the size of a cigarette lighter that you can attach to a lanyard or keyring, or just stick in your pocket. By the way – when this post was written there were no USB flash drives of capacities higher than 64GB. This is no longer true – there are now several models of 128GB USB flash drive and one 256GB USB flash drive – though no doubt other models will appear soon.
