What are the different types of memory cards?
In What are the different types of memory cards? Many of the consumer electronics sector products of today, such as digital cameras, cellphones, portable devices, and other small electronic devices, use memory cards as a common storage medium. Because flash memory is non-volatile, it can be erased, reformatted, and used again without losing its contents if taken off of the device.
The SD Association first introduced SD cards in the late 1990s, and they soon rose to prominence as the industry standard for portable storage. They have developed over time to satisfy the increasing demands of digital media by offering higher capacity and faster data transfer speeds.
Memory cards are flash-based storage devices that are usually small and light. A memory card reader, microSD card reader, or similar converter can be used to put the memory card into a device’s built-in slot.
Memory cards come in a few main varieties that are suitable for everyday electronics. All of these memory card kinds have different dimensions, and as technology develops, we observe that cards get smaller in size physically but get bigger logically with time. The several varieties are listed below:
Types of memory cards?
1. Compact Flash Card
In What are the different types of memory cards?, SanDisk invented the CompactFlash card (CF card) memory card format in 1994. It uses flash memory technology to store data on a small, portable device. There are no moving parts, and it can store data without a battery. To a wide range of computing equipment, users can add data using small memory cards. High-end digital single-lens reflex (DSLR) and video cameras now mainly employ CF cards as removable memory.
NOR flash memory was used in the creation of the first CompactFlash card. One benefit of NOR flash is that applications can run straight from the flash without requiring to be transferred into the system RAM of a device. All detachable memory cards, including the CompactFlash memory card and its main competitor, the Secure Digital (SD) card, now come with NAND flash memory by default since it is better suited for storing huge amounts of data.
Photographers use the CompactFlash, sometimes referred to as the CF card. Compared to SD cards, CF cards are less common and significantly larger. They provide greater run-time speeds and more storage.
Devices such as DSLR cameras, webcams, video and still image recorders, and professional photography all employ CompactFlash and CompactFlash Express (CFexpress) cards. CompactFlash (CFast) and XQD cards are the fastest CF card formats available. A plug converter is required to use CF cards in a PC card slot. If you have a memory card reader or passive adapter, you can also utilize them as a storage device.
CompactFlash cards come in two varieties, each with a different capacity:
Cards of Type I: 42.8 x 36.4 x 3.3 mm thick.
Cards of Type II: 42.8 x 36.4 x 5.5 mm thick.
2. Secure Digital Card
The SD card’s basic format is Secure Digital. The SD card is 32 mm by 24 mm and has a thickness of 2.1 mm. The maximum storage capacity of these SDHC (Secure Digital High Capacity) cards is 4GB. Compared to normal SD cards, these cards have a slower speed.
Secure Digital Cards, or SD Cards, are truly small flash memory cards made to offer large amounts of memory in a compact package. Numerous compact, portable devices, including mobile phones, digital video camcorders, digital cameras, handheld computers, and music players, use SD cards.
Secured credit cards are a special kind of card that wants you to deposit money when you open the account, usually equal to your credit limit. Each time you make a purchase, this money serves as collateral. Your lender may utilize the deposit to cover its costs if you default on your loan or don’t make payments on time.
3. Secure Digital High Capacity
Secure Digital High Capacity (SDHC) cards are made especially to hold high-definition images and videos. This card is identical to a typical SD card in terms of size and design. An SDHC card is any SD card with 4GB of memory support. SDHC cards have a maximum storage capacity of 64 GB.
A memory card format called Secure Digital High Capacity (SDHC) is used for recording and transferring digital data between varieties of electronic devices. An enhanced version of the original Secure Digital (SD) card, SDHC offers higher storage capacities and faster data transmission speeds.
In the What are the different types of memory cards? Importantly, because of file system formatting and technological differences, SDHC is not necessarily compatible with older devices that use ordinary SD cards. Although the majority of contemporary devices that support SD cards can also read SDHC cards, users should confirm compatibility by consulting the device’s specifications.
Digital cameras, webcams, laptops, cellphones, tablets, and portable game consoles are just a few of the gadgets that frequently employ SDHC cards. They offer more storage space for a variety of media, such as music, movies, and pictures.
Given below is the list of classes of SDHC cards with minimum speed.
The minimum speed supported by a Class 2 SDHC card is 2 MB/s.
The minimum speed supported by a Class 4 SDHC card is 4 MB/s.
The minimum speed that a Class 6 SDHC card can provide is 6 MB/s.
The minimum speed that a Class 8 SDHC card can provide is 8 MB/s.
A minimum speed of 10 MB/s is supported by a Class 10 SDHC card.
4. Secure Digital Extended Capacity
the SDHC card has been upgraded to the Secure Digital Extended Capacity (SDXC) card. The minimum speed supported by Class 1 SDXC cards is 10 MB/s, while the minimum speed supported by Class 3 SDHC cards is 30 MB/s.
Flash memory cards with a storage capacity of 32GB to 2TB—more than 60 times that of normal SDHC cards—are known as Secure Digital Extended Capacity (SDXC) cards. Engineers have used SDXC cards to achieve a data transfer rate (DTR) of up to 312 Mbps (millions of bits per second). The exFAT file system is used.
Here’s a more detailed explanation:
Storage Capacity: SDXC cards may store between 32GB and 2TB of data.
Larger file sizes are possible since they utilize the exFAT file system.
Speed: Up to 300 MB/s of transfer are supported by SDXC cards.
Compatibility: Only SDXC-compatible devices can use SDXC cards.
For the storage of enormous volumes of data, including 4K video footage, high-resolution photographs, and other data-intensive applications, SDXC cards are perfect.
With the Extended Capacity (XC) format, the maximum SD storage capacity is increased by more than 60 times, from the previous 32 GB (gigabytes) to 2 TB (terabytes). Engineers have used SDXC cards to achieve a data transfer rate (DTR) of up to 312 Mbps (millions of bits per second). The file system it utilizes is exFAT.
5. Microsecure Digital High Capacity
The maximum storage capacity of the Micro Secure Digital High Capacity (MicroSDHC) card is 32 GB. It has a 10 MB/s transfer rate, just like SDXC.
The SDXC and Micro Secure Extended Capacity (MicroSDXC) cards are identical and can store data up to 2 TB and more than 32 GB.
In this, what are the different types of memory cards? It is faster than the microSD and microSDHC at data transmission.
Details: –
Read/write speed: 10 MB/s, 3 MB/s
Dual voltage operation: Memory Stick PRO Duo compatible devices run at 3.3 volts, while modern cell phones run at 1.8 volts.
Ejection design that is controlled makes removal simpler.
SDHC host devices may use both SD and SDHC memory cards thanks to Sony/SanDisk Magic Gate encryption technology.
6. The Digital Picture Card Extreme
Digital camera flash memory that may be removed is called an Extreme Digital Picture Card, or xD-Picture Card. Olympus and Fuji Film developed it. It is 1.7 mm thick and is 20 mm by 25 mm.
Among them was a camera and webcam storage solution called the xD-Picture card. What an xD-Picture card is will be explained in this article.
The ‘xD’ in the xD-picture card represents “extreme digital.” The majority of SD cards and solid-state drives on the market today employ a flash-based NAND memory technology to store data. Originally intended to store high-pixel camera photos, card readers later made it possible for users to store other types of files as well.
XD-Picture cards were the smallest digital storage devices available when they started appearing on store shelves in 2002.
At the time, its 5 MB/s file transmission rate was wonderful. However, other manufacturers quickly caught up. Because mini SD cards were even smaller and had more storage space, xD image cards were finally phased out. It is likely that this card was discontinued in 2009.
7. Memory Sticks from Sony
The memory stick is a type of flash memory card that may be removed. A memory stick, sometimes referred to as a thumb drive or universal service bus (USB) flash drive, is a type of portable storage device that stores data using flash memory. It uses a USB connector to connect to a computer or other proper devices. Sony launched it in late 1998.
Memory sticks offer a number of benefits. They can hold a lot of data and are lightweight and portable. In addition, they are simple to use—all you have to do is plug them into a USB port to begin accessing or transferring your files.
Memory sticks come in a wide range of capacities. Memory sticks with storage sizes extending from a few gigabytes (GB) to several terabytes (TB) are available.
Sticks of memory are made to work with a variety of computers. It can be used on various devices as long as the computer has a universal service bus (USB) connector and supports the file system on the memory stick, which is often FAT32 or exFAT.
File transfers to a memory stick are easy. The memory stick should first be inserted into a computer’s universal service bus (USB) port. The files you wish to move can then be found by using File Explorer (Windows). The files can then be copied and pasted into the memory stick folder or dropped into the icon of the memory stick.
