I Will Cover This For You So You Will Have Peace Of Mind. 

 

 

****REMARK*** As I fed up seeing people losing data because of purchasing "CHEAP & FAKE" Micro Memory Cards like ( Samsung EVO, SanDisk, Kingston, Huawei, etc.)  I have decided to make my own BRAND "N & J SpeedMaster" with real capacity and 2 years of Manufactory Warranty but I will give you an additional year of warranty as I trust my product so the total years of Warranty are 3. Sounds great and pace of mind, right?

 

***REMARK*** Please Note That I Invested In The Product Not In The Pack. The Pack Is Basic But The Card Is High Quality

 

*** Please, read this before leaving Negative Feedback that the Card You have Purchased has less Capacity than the Advertised !!!

 

***HERE IS WHY***

 

Have you ever wondered where those Gigabytes are hiding? The truth is that they are not hiding at all.

 

It has to do more with the way card companies (and hard drive companies too) decide to annotate their products.

 

In English Kilo means one thousand (10001 = 1,000), a Mega is a million (1,0002 = 1,000,000) , a Giga is a billion (1,0003 = 1,000,000,000) and so on (Tera, Peta, Exa, Zetta & Toyya).

 

This system is called the SI unit system

 

In Computerish, however, the numbers are a bit different:

 

A Kilo means 1,0241 = 1,024, a Mega is 1,0242 = 1,048,576, a Giga is 10243 = 1,073,741,824 and so on. This is called the Binary units system.

 

So there is a difference in what Kilo, Mega and Giga mean and that difference is getting bigger the “stronger” the prefix is.

 

For Kilo, the difference is only 2.3%, for Mega, it is 4.6% and for Giga, it is 6.8% – see a pattern here?

 

Back to the memory cards.

 

Memory cards manufacture choose to use the SI system to denote cards sizes. Our computers and card readers use the binary system for size calculation and here is where the missing Bytes are.

Of course, the card companies are covered, they do mention this fact on their sites (in a small asterisk, or with hover text that is revealed when you hover over a small asterisk).

 

If you followed the math, you probably realized that the toll this calculation method in taking gets bigger, the bigger the data units are. So while the toll on a 1GB memory card in way smaller than on a 1 tera hard drive. Have a look at this table to sum things up:

****REMARK***

Difference between "Real" Memory Card and "Fake" Memory Card

 

***"FAKE"***

  They are cheap and looks like the originals

They have less capacity than the advert on them for example:

 

You have purchased 128GB well cheap and thinking you had a great deal, right? This "FAKE" card probably have  8GB "real" capacity and the rest 120GB is "virtual" capacity. What does it mean "virtual"?

It means that you can see it on your devices but you can not store any files on it. Once the card reaches the 8GB mark any other data above gets lost.

 

***REAL***

The real memory card has full memory capacity as the advert and has the right speed. 

 

 

*** Read this carefully***

N & J SpeedMaster is:

Ideal speed and performance for Full HD, 4K Ultra-HD recording and data transfer between any computer and/or android Smart Phone, Cameras, Tablets, PC and DSLR and drone Shockproof, waterproof, X-ray proof and Magnetic proof.

 

****REMARK*** Please be aware that you have to check your device for the maximum memory allowance and correct speed, before purchasing any memory card. Deferent devices, allow deferent, maximum memory capacity. For example, if you have an old cell phone it may only use a maximum memory chip of 16GB so, a 256GB or more will not function in that device. It means, that you need to buy lower memory capacity SD card for this device. Also, you have to check if your device requires the memory card to be formatted. You can format it on your computer or laptop before you start using it. Otherwise, the memory card may not function properly.

 

****Helpful Information***

 

SDHC vs SDXC What does it mean?

Firstly lets deal with the acronyms,  SDHC  stands for  S ecure  D igital  H igh  C apacity and  SDXC  stands for  S ecure  D igital e X tended  C apacity

 

Card Capacities:

 

Each type of card has a memory capacity range, and these are:

 

  • SD  standard – Up to 2GB SD memory card using FAT 12 and 16 file systems
  • SDHC  standard – over 2GB-32GB SDHC memory card using FAT32 file system
  • SDXC  standard – over 32GB-2TB SDXC memory card using exFAT file system

 

Card Speed: Class 4, Class 6, Class 10, UHS-1 and UHS-3

Each  SD  or  Micro SD  card has a speed rating, called a  Class . Larger Class numbers correspond to a faster level of writing/recording (minimum performance) allowing files to be written to the card or recorded at a higher speed or definition ( HD/4K ).

 

The Class rating system rating corresponds to the minimum read speeds in MB/s as below

 

  • Class 2 – 2MB/s (minimum recording speed),
  • Class 4 – 4MB/s,
  • Class 6 – 6MB/s,
  • Class 10 – 10MB/s.

 

As an example for demonstration purposes,  Class 2  is sufficient for  SD  video recording, whilst  Class 4  and  Class 6  support HD recording. The Class rating is displayed on the card, by a number nested inside a circle.

 

After the  Class 10  classification, it becomes a little more complicated.  An additional standard called  UHS  was introduced, which allows cards to reach higher speeds. Here we see a similar system –  UHS Class 1  (or just  U1  or  U-I ), which has a minimum performance rating of 10MB/s writing speed, while  UHS Class 3  (or  U3  /  UHS-III ) has a rating of 30MB/s.  UHS Class 3/III  supports 4K video recording.  UHS speed classes are shown on the card with a number inside a U.

Confusingly,  UHS Class 1  and  Class 10  refer to the same 10MB/s speed, so sometimes you’ll see cards that are labelled both as  Class 10  and  UHS-1 .

 

If you have an  Action Camera  (Such as  GoPro  or  EvoDX ) that records  HD  at either  1080p  or  4K  you really need to be thinking about purchasing a  UHS-3/III  card, for the best performance and writing speed.  Some cheaper action cameras will buffer the recording, but this is not practical in the slower card speed classes, and may cause juddering or stuttering of the recorded footage, as well as other issues. Similarly with the latest Digital SLR Cameras (especially in modes such as sport, multi-frame or burst-mode) where multiple images are taken, having a faster card will allow you to review the images much sooner (less waiting for the images to write to the card).
