If you are willing to expand storage in your mobile, tablet, camera, or any handheld gaming system, the memory card is the card that you should use. There are many options available in the market, due to which you may feel confused. You should pinpoint the type, storage capacity, read/write speed, etc. Besides, you should know whether the card comes with data protection capabilities or not.
The best memory card always contains an adapter. Therefore, while you will buy this, you can find an adapter. The adaptors allow the devices to work with various types of memory cards. Some devices are available in the market, enabling you to use two types of memory cards or more. It is why you should figure out the best one that suits you most. This article contains the best memory card on the market, and it will help you select the suitable one for you.
What is a memory card?
A memory card is a storage device used to store digital data and electronic information using flash memory. It is a form of flash memory used in electronic gadgets like digital cameras or video game consoles. In addition, it helps store information, pictures, songs, saved games, other PC files, etc. Flash memory devices don’t have any moving parts, due to which these are not going to be damaged so easily.
What does a memory card do?
A memory card is used mainly for adding digital storage to a device. You only have to insert a small plastic rectangle item containing memory chips, and it can store files for a long time. People use the additional memory to expand the phone’s storage and keep videos, images, apps, audio files, games, etc.
How do memory cards work?
You should know first that a memory card is a typical device made of a plastic case & metal connectors. It contains many different technologies like flash memory, a controller, and other parts, and the latter quality determines both speed and quality.
File Allocation Table or FAT helps to arrange Memory card file locations. The files will not be erased while you delete any picture or data. It is the record from the table of contents, which is deleted. It indicates that your PC or other electronic devices cannot show the file location in a folder. However, the File you have deleted is still available on the memory card. You should know that these data remain stored on the memory card till you are not overwriting this. Therefore, if you have mistakenly erased the essential files, you should stop using this instantly. You can recover the deleted information with specialized software.
How do I use my memory card for storage?
If you find your mobile not prompting automatically, you should try the steps.
- First, your job is to put your SD card on the Android mobile. Then, you should wait for this to be recognized.
- Navigate to the Settings, and then move to the Storage section.
- After that, your task is to click on the name of the SD card.
- You can see three vertical dots available on the top right corner of your mobile display. Click on the dots.
- Hit Storage Settings.
- You are required to choose “Format” as an internal option.
- Next, your job is to click on the Erase & Format at the prompt. At last, your Android device enables you to migrate the data.
Memory card sizes:
Generally, the memory card is available in 8GB, 16GB, 32GB, 64GB, and 128GB capacities. In addition, a few high-capacity cards are available, which can hold terabytes (TB) of data.
When you choose the best one to buy, the first thing you should note is their amount of storage. In short words, you can say this memory size. In some years, the memory sizes have boosted remarkably. Previously, 1GB size was enough for people, whereas 128 GB is not uncommon in recent times.
What types of devices need memory cards?
Nintendo Wii and devices that are similar to this use SD cards. The cards took off as the storage medium while photography, with cameras dispensing and film rolls.
Like digital cards, people use memory cards in smartphones to store data (images and music), camcorders for storing video, etc.
These are used in televisions, portable game devices, printers, DVD recorders, and other electronic devices. Plenty of televisions even has card slots that enable you to see any stored images on a big display. A few printers will allow you to print directly the pictures stored on a card.
It is possible to swap cards from one product to another. However, you should know that different devices use different memory card types. Whether there is a Memory Card in your device already, and you want to buy more gear, ensure that the card is similar.
Types of memory cards:
We have given here different types of memory cards available in the market. CompactFlash and Secure Digital ( Micro and Normal) are basic memory cards.
CompactFlash:
This type of card is specially designed for professional photographers. You can find CF cards in high-end DSLRs like Canon EOS-1D X Mark II. Compared to the size of SD cards, these come in a larger size but are used less commonly.
These are physically bulky than SD cards and less commonly used. Besides, CF cards have more significant capacities and enable you to run at very high speeds.
Secure Digital:
It is the basic format of the SD card. The thickness of the SD card is 2.1 mm, whereas the size is 32 mm x 24 mm. Their performance is quite good, but these are not as quick as other SD cards.
Its size is limited to 4GB above which anything will be an SDHC card.
Secure Digital High Capacity:
The SDHC card was designed to fulfill the high demands for high-definition photography and video. Like standard SD cards, these come in similar physical sizes and shapes. But these can fit the specifications of version 2.0. This type of card is limited to 64 GB above which anything will be considered an SDXC card.
It has classes— 2,4,6,8,10 with a minimum speed of 2 MB/s, 4 MB/s, 6 MB/s, 8 MB/s, and 10 MB/s.
Secure Digital Extended Capacity:
This type of card is a beefed-up SDHC card. Their range of size is between 64 GB and 2 TB.

Why do we have different Memory Cards?
Each camera manufacturer generally uses different cards of various sizes & shapes. Along with the card, they also use different shapes of lens mounts, flange distances, lens sizes, batteries, wires, etc.
The cards are available in different sizes according to storage and physical shape. Manufacturers like Canon are willing to use Compact Flash (CF) memory cards, and other cards can use the smaller Secure Digital type.
Make sure that you have checked the camera specifications before buying the cards. If you want, then use the Micro Secure Digital with an adapter. However, it is not possible to make SanDisk memory cards smaller.
How much can I select a good memory card?
The amount of data you can store on the memory card relies on mainly three factors. These are — the device, data type you want to store, and the data quality.
When you use High megapixel cameras, you need to have more memory space for each shot than low-megapixel models. The type of information will always determine the amount you can fit on a card. Pictures need more space than text documents, whereas digital music can consume even more. Besides, video is another space hog.
It is the quality of the files that is the ultimate determining factor. The aspect will determine how much is possible for you to cram onto a memory card. The better quality you want to have, the more space it will require. Compared to the low-resolution shots, the high-resolution images need more memory space. Whether you shoot in RAW mode on your camera, every File will need more space than a standard JPEG image. If you want to store music compressed at a good quality, it can take additional space compared to those with average compression. We know this as bitrate also.
What is inside the memory card?
The memory card components are some transistors and an oxide film. These are used to construct the internal circuits of memory cards. The components are used to create two types of circuits: the floating and control circuits. First, you need to place the transistors to form a junction, and after that, you should derive a network with some rows and columns.
Oxide separation sheet is a significant component of the device, which you need to place in between both circuits. In addition, it helps to link the processing flow between the printed circuits.
What is the difference between a memory card and a secured digital card?
Memory card speed:
When it comes to speed, the memory cards can vary, and these depend on how they can read and write information. However, the speed ratings and the marking style vary according to the memory card type.
Speed classes:
Speed Class defines a minimum sequential writing speed offered by a memory card. A bus speed is also there that you can define as “UHS.”
It displays the theoretical maximum offered by a card over the bus. The UHS Speed Class and Video Speed Class specifications also define minimum sequential write speeds.
Bus interface:
We have given here different bus interfaces and their limits. Therefore, this short table can summarize different bus interfaces.
| Bus Interface | Compatible Memory Cards | Maximum Bus Speed |
| High Speed | SD, SDHC, SDXC | 25 MB/sec |
| UHS-I | SDHC, SDXC | 104 MB/sec |
| UHS-II | SDHC, SDXC | 312 MB/sec |
| UHS-III | SDHC, SDXC | 624 MB/sec |
Here, you can see a massive difference between High Speed, UHS-I, UHS-II, and UHS-III cards for maximum bus speed. The original cards have speeds like 25 MB/sec, whereas the UHS-I bus interface has a speed of 104 MB/sec.
The new UHS-II bus can multiple the speed at 312 MB/sec three times. The new UHS-II standard came to the market recently, but it can enable insane speeds of up to 624 MB/sec.
You should know that cards with a quick bus speed need a memory card reader/writer to support the bus speed. For instance, when you buy a memory card with a UHS-II bus interface, you should ensure that the card slot on the camera should support UHS-II. Otherwise, you can experience different reliability problems. The same thing is applied to a memory card reader on the PC, and it should support UHS-II for supporting the higher speeds.
What is an UHS speed class?
UHS stands for Ultra High Speed, and it is the quickest performance category. The UHS speed class lets you know bus-interface speeds of a maximum of 312 MB/S. Its primary purpose is for SDHC and SDXC memory cards, which support SDHC and SDXC devices.
It comes with two ratings within the UHS Speed Class:
U1 (UHS Speed Class 1): 10 MB/s is the minimum write speed of UHS Speed Class 1.
U3 (UHS Speed Class 3): 30 MB/s is the minimum write speed of UHS Speed Class 3.
It was the SD Association that introduced the UHS Speed Class in 2009. This one uses a new data bus that cannot work in non-UHS host devices. If you use this type of memory card in a non-UHS host, the standard data bus “Speed Class” rating becomes default rather than the “UHS Speed Class” rating. The cards have a full higher potential that allows you to record real-time broadcasts to capture large-size HD and professional HD videos.
Video Speed Class:
This class offers the quickest speeds available. It is perfect for ultra-high-resolution videos, top-quality videos, multi-file recording in drones, and 360-degree cameras. The speed class is compatible with HD formats up to 8K video in drones. Besides, it supports action cams, 360-degree cameras, and VR cameras.
V6 (Video Speed Class 6): 6 MB/s is the minimum write speed of Video Speed Class 6.
V10 (Video Speed Class 10): 10 MB/s is the minimum write speed of Video Speed Class 10.
V30 (Video Speed Class 30): 30 MB/s is the minimum write speed of Video Speed Class 30.
V60 (Video Speed Class 60): 60 MB/s is the minimum write speed of Video Speed Class 60.
V90 (Video Speed Class 90): 90 MB/s is the minimum write speed of Video Speed Class 90.
Video Speed Class is also referred to as “V Class.” The SD Association created the speed class to determine cards to manage higher video resolutions and recording features. In addition, the speed class can guarantee minimum sustained performance to record videos.
The other speed classes can not be optimized. Besides, these can’t accommodate the recording of multiple video streams, 360 capture, virtual reality content, etc.
What is Minimum sequential write speed:
‘Sequential Read/Write Speed’ indicates the quick speed at which the drive can write or read the data from a series of blocks. Speed classes like the UHS speed class or video speed class define minimum sequential write speed.
How safe is the data stored on memory cards?
If you are thinking about the safety of your information, then these have a few unique benefits compared to hard disks or CDs/DVDs. First, these are more shockproof compared to other storage mediums. However, if it is a standard hard drive, there is a chance of damage due to moving parts.
Compared to CD/DVD, these are far less fragile. A memory card can take a scratch or two. But when it comes to scratches for a CD or DVD, you may experience data loss or an unreadable disk. Some cards are available that are so small that they can lose the whole card itself instead of by some other accident.

Memory Card Best Practices:
- You should keep the card consistently formatted in the camera. When you format your card, it will erase all images. You can format it in two ways— in the camera or on the PC. However, you should know that it is better not to format a card on the PC. It cannot generate the proper directory for the camera, and the files are not saved accurately.
- You should not use one card in many cameras. Make sure that you are not using the same one in different camera brands. The reason is that you may damage the card via overlapping incorrectly. Whether you want to switch cameras, you should format the card in the new camera again before using it.
Best Practices:
- Use a card for one year at least. However, you should not leave cards inactive for a long time.
- You should use cards with smaller capacities. It may happen that you have lost cards, broken them, gotten corrupted, etc. As you are not willing to lose the huge data amount, it is recommended to use 64GB or 32GB cards. However, if you are an experienced videographer, you will need higher-capacity cards.
- Ensure that you are using a card reader for sharing images. With the help of card readers, you can transfer pictures quickly. Besides, these corrupt your card far less compared to a USB cable while being used to the PC directly.
- You should not use a microSD card in a slot for an SD card. It is because microSD cards are available at a low price. However, in this case, the adapter piece is not designed to handle the data amount necessary for your computer, and it can damage your card or corrupt your data. Therefore, you should only use the microSD cards in native devices, such as drones, action cameras, or mobile devices. In this case, you can use the adapter piece to download your files on the PC.
How to Store Your Memory Cards:
We have given here three methods to store memory cards.
Method 1:
How to Mount a Micro SD Card for Android Phones
Step 1:
You should first see whether your mobile is compatible with SD expansion or not. Multiple new mobiles are trending away from SD cards’ use. You can check the user manual or visit the manufacturer’s web page to check if it is compatible with SD cards.

- Your first job is to move to the Settings menu and open it.
- Next, you should hit the Storage or SD and Phone Storage option. Finally, you can get the option below Device care.
- Next, your job is to click on the SD Card option.
- After that, hit the option Unmount.
- Now, you should click on the SD card.
- Finally, your task is to hit Mount.
Step 2:
Remove this and then go for the inspection to check if it is damaged. You should search for the missing gold prongs. Now, check to ensure that no dents or damaged areas are on the card.
Step 3:
You should now clean the card. If the card looks dirty, then use a soft cloth and some lukewarm water or metal cleaner to clean. Ensure that the card is dry entirely before reinserting this into the card.
Step 4:
Try to mount the card again. As soon as you remove the SD card and inspect this for dirt, you should insert this again back into the device. Then, remount this again. Sometimes, you can get rid of the problem by ejecting and reinserting.
Step 5:
You should again format the card in exFAT or FAT32 format. If you have used this on another device, it may format in the wrong Format. Format it again. It helps to remove all information from your SD card, and you should insert this into an SD card reader. Then, perform the steps to reformat the card in the correct Format.
- Your first job is to tap on Ctrl + E to open File Explorer.
- Then, you should hit the PC.
- After that, your job is to tap on the SD card.
- Next, you should tap on Format.
- Choose the exFAT (recommended) or FAT32 option under “File System.”
- Finally, you should tap on the Start option.
Step 6:
You can check the card on different devices if it cannot mount accurately. If you find your gadget working in another device, ensure that the SD card slot can be the culprit. But if the card cannot mount even on another device, you have to replace the SD card. Ensure that you have charged your device entirely before putting the Sd card into another device.
Memory Card Readers:
Your PC may not contain the actual default memory card reader, or there may not be any card reader. Card readers allow you to use them efficiently. In addition, there are portable attachments that need to be plugged into a USB port to share images, videos, etc., to your memory card. These come in a huge variety with various combinations.
How to insert a Memory Card into your PC?
If you are willing to use a memory card, plug it into the proper card slot. You can do this directly on the console of the PC or through a memory card adapter connected to a USB port. Windows detects the card immediately and mounts this into the system. As a result, you will see the available data instantly.
Make sure that you should not put force on a memory card to insert it into a slot. If you cannot get the card into one slot, you should use a different slot. These are inserted labels side up, and you should insert label-left for the mounted memory card readers vertically.
You can see the AutoPlay dialog box available when you have inserted the card. You should use a dialog box to select the “how to view the card’s contents” option. For instance, you should choose the View Pictures option for seeing pictures stored on the card from a digital camera.

Memory Card Buying Guide:
You can find modern DSLR and mirrorless cameras, mostly with memory card slots. If you are willing to use this, insert it into the camera supporting it. Remember the aspects before you are going to buy a new memory card.
While selecting the best one, it may seem that the biggest card is best. Whether you capture many pictures without importing them to the PC, you should use a giant card. It is suitable for travel photographers as they can go days without sitting down. The drawback, in this case, is whether you have lost the card; no pictures will be available after that. But when it comes to a small card, you may need to back up the pictures.

Speed:
This is a significant factor that can make a good experience by storing images or breaking them. You may not want to wait for hours to share pictures from the card to the PC. SD cards are available with a limited speed and are used for reading and writing.
