Written by: Kevin Ashwe

A 64 GB memory card is the perfect way to store your precious memories. Here's our guide on how to get the most out of it.

Unless you’ve been living in the caves or a lonely island for the past two decades, then I am sure you have heard about SD cards and must have used one before. Today, let’s talk about the 64 GB Memory CardCheck Latest Price . And we’ll tell you all you need to know about it to get the best out of it, in case you have one already or you are planning to get one. 

 

 

What Is A Memory Card?

A memory card is a small-medium card used for storing digital information. It is mostly used in portable devices such as mobile phones, laptops, cameras, video games, etc.  Compared to the traditional hard drives, SD cards are more resilient because they do not have moving parts like the former. The absence of these moving parts means that they can fall and suffer accidental bumps and not crash. 

 

 

They are also more ideal for electronics because they can be written to thousands of times. And since they can also retain their data without a power supply, they are suitable for electronics that have strict power requirements.

 

 

 

Do You Need A 64 GB Memory Card?

Do you have pictures? Of course, you do! If you are not saving them to share with family and friends on social media, then you are probably storing them for memories. How about videos? I know you like the idea of picking up your phone and seeing a movie while on the go.

 

Are you a gamer, a professional photographer, or videographer? The bottom line is that we all need memory cards. It is just a matter of deciding the size that is most suitable for you, and one of the best choices has to be the 64 GB micro SD card because, with it, you have little or no limitation.

 

 

 

How Do They Store Data?

In an SD card, data is stored on a group of electronic components known as NAND chips. Through these chips, data can be written and stored on SD cards. These NAND chips are built in such a way that they do not wear or tear, meaning that several data can be written to them throughout their lifetime. This is why SD cards are resilient and long-lasting types of memory cards.

 

 

Basically, there are two main types of memory card widely used today, which are the Compact Flash (CF)Check Latest Price and the Secure Digital (SD)Check Latest Price . The SD card is more commonly used. So, we will focus more on our discussion on the SD card.

 

 

CompactFlash Memory Cards

 

 

The Compact Flash is widely regarded as the memory card for the professional photographer. DSLR (Digital Single Lens Reflex) cameras make use of this type of memory card. They are bigger than the SD card in size, have bigger capacities, and run at very high speeds. 

 

 

Secure Digital Memory Cards

 

 

The Secure Digital is the most basic format of the SD card. They are version 1.0 of the SD card, which means that there are better versions of it. SD cards perform quite well but not as good when compared to current versions. They are limited to 4 GB in terms of capacity, anything bigger than this falls under the SDHC.

 

 

Secure Digital High Capacity Memory Cards

 

 

 

 

The SDHCCheck Latest Price was tailored specifically to meet the demands for high-definition photography and video. They have the same shape and size as the standard SD card but work better. SDHC may also be called the version 2.0 of the SD family. Currently, they are limited to 64 GB in terms of capacity, and anything higher is classed as an SDXC.

 

 

Secure Digital Extended Capacity Memory Cards

 

 

 

The SDXC is just an extended version of the SDHC. These cards start from 64 GB and can reach sizes of 2 TB.

 

 

Secure Digital Ultra Capacity Memory Cards

Announced in June 2018, the SDUC supports data of more than 2 TB up to 128 TB at speeds of 985 MB per second. As they are fairly new, these are rarer and harder to get than other types of SD cards, so be sure to keep your eyes peeled!

 

 

  • SD – Up to 4 GB
  • SDHC – From 4 GB to 64 GB
  • SDXC – From 64 GB up to 2 TB
  • SDUC – Anything from 2 TB up to 128 TB

 

 

Micro Secure Digital Cards

 

 

 

The Micro Secure Digital (MicroSD) is the micro version of the SD with sizes of 15mm x 11mm and 1mm thick.

 

 

Micro Secure Digital High Capacity

The Micro Secure Digital High Capacity (Micro SDHCCheck Latest Price ), introduced in 2007, is the micro version of the SDHC card. It comes with a storage capacity of 4 GB up to 32 GB and can transfer data of 10 MB per second. 

 

 

Micro Secure Digital Extended Capacity 

The Micro Secure Digital Extended Capacity (MSDXC) is the micro version of the SDXC but has a storage capacity of over 32 GB up to 2 TB. It has a faster transfer speed when compared to the MicroSD and MicroSDHC.

 

 

  • MicroSD – Up to 4 GB
  • MicroSDHC – From 4 GB to 32 GB
  • MicroSDXC – Anything higher than 32 GB

 

 

Classes of Memory Card

Memory cards are classified according to their writing speeds or commonly known as speed classes. All memory cards are not built the same. Some are suitable for our everyday activities, like taking pictures on smartphones or storing some other media files. Generally, this type of activity doesn’t require SD cards at fast speed. Still, if you’re into professional photography or shooting high-resolution videos, then you will require fast speed SD cards like the Class 10 cards. For this reason, manufacturers classified them into four different speed classes and differentiated by each one’s serial minimum data writing speed. They are – Class 2, Class 4, Class 6, Class 10. 

 

 

We also have two Ultra High Speed (UHS) speed classes – 1 and 3 -, but they are largely expensive and mostly for professional use. You can only use UHS on devices that support it.

 

 

Speed Class – Class 2

Minimum Serial Number – 2 MB/s

Application – Standard Video Recording 

 

 

Speed Class – Class 4

Minimum Serial Number – 4 MB/s

Application – HD and Full HD Video Recording

 

 

Speed Class – Class 6

Minimum Serial Number – 6 MB/s

Application – Full HD Video Recording, HD Still Image Continuous Recording 

 

 

Speed Class – Class 10

Minimum Serial Number – 10 MB/s

Application – Full HD Video Recording, HD Still Image Continuous Recording 

 

 

Speed Class – UHS Class 1

Minimum Serial Number – 10 MB/s

Application – 4K2K Video Recording 

 

 

Speed Class – UHS Class 3

Minimum Serial Number – 30 MB/s

Application – 4K2K Video Recording 

 

 

SD Card vs. Memory Card

Normally, people refer to any memory card as “SD card”, but the SD card is just one of the memory cards out there. In fact, any card used to increase the storage capacity of a device such as a phone or a camera is a memory card, and the SD card is one of them. SD is an acronym for Secure Digital, and the SD card is a non-volatile memory card format that was developed by the SD Card Association (SDA). It is developed for use in portable devices.

 

 

The 64 GB SD card is an ultra-fast card that can help you store your high-quality images and HD videos to the tune of 64 Gigabytes. It is built to interface perfectly with your cell phones, cameras, camcorders, TVs, computers, etc. 

 

 

Uses of Memory Cards

Memory cards or memory stickCheck Latest Price find great use in consumer electronics mainly for storage. It is a popular and important means of storing huge gigabytes of data in a tiny size device. They find use in any device where the user may need to write to, store in, or delete from. Such devices include mobile phones, digital cameras, computers, camcorders, palmtops, video game consoles, etc.

 

 

  • In the choice of card type, devices that can afford to come in big sizes such as game consoles tend to use full-sized cards, but those that emphasize portability such as mobile phones are best suited for SD cards.

 

  • Since the adoption of the microSD cards in smartphones, the smartphone market has seen a great boost because it has given both manufacturers and users greater flexibility. 

 

  • Due to their minute sizes and huge memories, they are also finding uses in newer technologies such as in-action cameras and cameras in drones.

 

  • Gadget manufacturers are also developing newer ways through which SD cards can be used. We can see that in the fact that newer versions of Android and Windows mobile operating systems now allow applications to run directly from microSD cards. This is opening a window for a whole new usage model for these SD cards in mobile computing.

 

  • These electronic devices use SD cards through built-in slots an external adapter. There are adapters for USB, PC cards, parallel printer ports, and so on. Adapters also exist that enable us to use SD cards in devices built for use with other formats like the CompactFlash. SD cards can also be used in a floppy disk drive through the FlashPath adapter. 

 

  • While SD cards are great for a wide range of electronic devices, they are not the most economical option for devices that requires just a small amount of non-volatile memories such as in radios. They are also not the best option for electronic applications where much higher storage capacities and greater speeds might be desired. In such cases, other flashcards such as CompactFlash are preferable. However, memory cards may find suitable for such purposes because of evolving memory technologies like the new SD 7.0, which is capable of holding files of up to 128 TB.

 

 

How Big Is A 64 GB Memory Card And What To Store In It?

Because of the miniaturization of electronics that is aimed at improving portability and mobility, the 64 GB memory card is built small, measuring just 32mm by 24mm by 2.1mm thick. But this small memory stick can hold all of your multimedia documents. They are used for storage of different data types such as audios, pictures, videos, and other file formats. These types of data are stored using flash memory which essentially is the ability of a medium to retain data without power supply. 

 

 

How Many Videos Can It Hold?

Several factors can affect the number of videos that a 64 GB memory card can hold. Some of them are recording speed, video recording time, and the size of the video. For example, a 64 GB recording speed SD card holds 320 mins off 24 MBps video while it can hold up to 2560 min of a 6MBps video recording time.

 

 

64 GB Memory Card How Many Photos?

A 64 GB memory card can hold up to 2132 photos of 24-megapixel rating.

 

 

Why 64 GB Memory Cards Get Corrupted?

The common causes of card corruption are viruses, abrupt interruption of data transfer, abrupt removal of SD card while transferring files, sudden unmounting without following due process. 

 

 

How To Recover Lost Files In A Memory Card

Some memory card manufacturers have recovery tools that you can use to recover damaged or lost files. So when buying a card, endeavor to ask for the recovery tool.  

 

 

How To Protect Your 64 GB Memory Card

 

 

Write Protection

Many SD cards are equipped with a lock feature that helps keep files in it intact. This feature prevents the sudden loss of data stored in it. The lock feature is a small switch, which prevents any new data from coming in or old data to go out when it is enabled. Every one of your electronics will respect this lock because it is built into the SD card itself. You can toggle the switch on and off. If you feel that you want to take off the protection so you can write to or delete it from the SD card, then you can toggle off the write protection. By doing so, you will be unlocking the SD card for use again.

 

 

64 GB Memory Card Counterfeits And How To Detect Them

The SD card market today is saturated with counterfeits. These counterfeits report a fake capacity, crash easily, or run very slowly. There are software tools you can use to detect fake ones even if you are not entirely geeky. The process involves copying random files into the SD card until it reaches the full capacity and the card cannot take any more files. Once done, copy the files back and compare them with the former files either by comparing the checksums like MD5.

 

 

Alternatively, you can just attempt to compress the files you copied back from the SD card. A substandard SD card will lead to easily compressible uniform data such as repeating 0xFFs because these counterfeited SD cards allow users to read backfiles and these backfiles consist of the highly compressible data.

 

 

Buying a 64 GB Memory Card

When buying a 64 GB memory card, there are a few things to consider. They include:

 

 

Physical Size

There are three sizes which are the original format measuring 32 by 44mm, the miniSD format measuring 21.5 by 20 mm, and the microSD measuring 11 by 15 mm. You should know the size that is compatible with your device before purchasing. 

 

 

Card Speeds

They come in different classes which stand for different speeds. Class 6 is 6MBps; Class 4 is 4MBps, and so on. The specifications of your device can suggest for you the speed with which it can write to a storage device.

 

 

Storage Capacity

This is another consideration, but since we are talking exclusively about 64 GB, we don’t need to dwell much here. However, be sure to know if your device can support 64 GB external memory because not every device can.

 

 

Bus Speed

This is the speed at which your device can send files to the card. There is class 10, and other classes, but the most recent and preferred ones are the Ultra High-Speed Bus UHS-1 and UHS-2.
