USB Flash Drive: FAQ

USB Flash Drive: FAQ


Lets just get this little Warning for Dummies  out of the way real quick, then we will move on to the real questions.... mmmmmk?

***Please Note*** When you see a 128GB flash drive on ebay for $5 bucks, it is because they are FAKE and do not work. There are hundreds of listings out there selling fake ones that claim to be 3.0, we have personally bought these to test them... after about 4 GB of data your memory card becomes corrupt and you lose all your files. You ALWAYS get what you pay for! Shop S2G with confidence, we have tested all supply chains with the h2testw program to be certain you are getting a legit capacity flash drive with promised true 3.0 speeds.  


Q: I can buy higher capacity on Ebay for less than $10 bucks, why are yours so expensive?

A: Sure, if you want Fake product. Seriously... do you really think that is real? If 16gb is about $10, how can 256gb also be $10? The answer is because they are FAKE... duh. Read the reviews.


Q: Why do people buy thousands of them if they are fake?

A: We have no clue. There are plenty of reviews validating that they are fake, yet people waste their money anyway... mind is blown.


Q: They even offer a 30 day money back guarantee, are you sure they aren't real?

A: No legitimate business could sell 256gb for $10, they would LOSE money. It isn't real.


Q: I would still rather buy a fake one for $5 bucks because it is cheaper then $40, do you have a 5 dollar hollar?

A: YES, if you would still like to waste your money, please take these off our hands... as they are fake from ebay and we do not want them.


Now that you're too smart to fall for the "too good to be true scam", lets move on to the real questions...


Why Choose Our USB Sticks?

When it comes to buying a flash drive, most people follow with interest of only storage capacity and price. Actually, it is the chip that has the greatest importance. There are a lot of USB sticks sold online or in a the market at a low price, but some of them use recycled or poor quality chips to reduce cost.

Your data is unsafe with these low quality flash drivers as they are likely to be damaged after a couple months of use; what is more tricky, is that it's almost impossible to determine the quality of a flash drive by the appearance. (See below)

But we choose our suppliers carefully, higher quality gives you longer service life and protects your data safely. They are surely worth the price!

This one is a waterproof-chip, using specially sealed black housing (see below) to keep your data even safer.


1. Is the USB flash drive real capacity?

YES, our USB flash drive is real capacity, you can use the h2testw program to test it. We have tested ALL supply chains (and found many fakes) to be certain ours are legit.
H2 test is the most authoritative testing software in the world. You may download it for free and test yourself here...

See our link in FAQ #3, notice how they talk about fake ones on amazon...

2. Why the USB flash drive real capacity is not correct capacity?

Flash memory vendors are using decimal arithmetic: 1MB = 1000KB, 1G = 1000MB calculated, the operating system using binary arithmetic: 1MB = 1024KB, 1GB = 1024MB;
Besides, a portion of the memory capacity on flash storage device is used for data management functions.

About Real Capacity
8GB = approximately 7.4GB-7.85GB
16GB = approximately 14.2GB-15.8GB
32GB = approximately 28.2GB-30GB
64GB = approximately 58GB-60GB


3. What is the difference between USB 2.0 vs 3.0?

3.0 (blue) gives you 10x the speed, and allows you to read AND write at the same time! If you transfer larger files you will definitely want a 3.0 (example... 60gb transfer on 2.0 = over 5 hours, 3.0 = half hour). For more detailed information about 2.0 vs 3.0, follow this link

USB 2.0 vs 3.0

Attention: When you put a USB 3.0 Drive into a 2.0 Interface Device, the Reading & Writing Speed of the 3.0 Drive can not reach the normal 3.0 Speed; When you put a USB 2.0 Drive into a 3.0 Interface, the Transferring Speed of USB 2.0 can improve, but still won't reach the normal USB 3.0 Speed.
