All you need to know about storage, finding the right sd card and more!

Secure Digital Card (SD Card)

Secure Digital (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices. The SD technology is used by more than 400 brands across dozens of product categories and more than 8,000 models.

SD comprises several families of cards: the original, Standard-Capacity (SDSC) card, a High-Capacity (SDHC) card family, an eXtended-Capacity (SDXC) card family, and the SDIO family with input/output functions rather than just data storage.
​

Types of SD Cards

Compatible with Samsung Galaxy Young

Standard SD or SDSC Card (the one came with your phone from Samsung)

The standard SD card measures 24 mm by 32 mm by 2.1 mm and has a maximum storage capacity up to 2 GB. The compact design makes it ideal for portable storage of photos, songs and video files, replacing the need for bulky tapes and discs

SDHC

The Secure Digital High Capacity (SDHC) format, defined in Version 2.0 of the SD specification, supports cards with capacities up to 32 GB. The SDHC trademark is licensed to ensure compatibility.

SDHC cards are physically and electrically identical to standard-capacity SD cards (SDSC). The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in Version 2.0 (see below), and the fact that SDHC cards are shipped preformatted with the FAT32 file system.
​

NOT Compatible with Samsung Galaxy Young

SDXC

The Secure Digital Extended Capacity (SDXC) format supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification.
​

SDIO

A SDIO (Secure Digital Input Output) card is an extension of the SD specification to cover I/O functions. Host devices that support SDIO (typically PDAs like the Palm Treo, but occasionally laptops or mobile phones) can use the SD slot to support GPS receivers, modems, barcode readers, FM radio tuners, TV tuners, RFID readers, digital cameras, and interfaces to Wi-Fi, Bluetooth, Ethernet, and IrDA. Many other SDIO devices have been proposed, but it is now more common for I/O devices to connect using the USB interface.

SDIO cards support most of the memory commands of SD cards. SDIO cards can be structured as 8 logical cards, although currently, the typical way that an SDIO card uses this capability is to structure itself as one I/O card and one memory card.
​

SD Card Classes

What is the SD Speed Class?

The SD Association has established standards that rate the minimum data transfer in SD, SDHC, SDXC, SDHC UHS-I and SDXC UHS-I memory cards and devices. The speed rates were established based on the needs of movie and video companies because video recording requires certain writing speeds when recording the data onto a memory card. The SD Speed Class and UHS Speed Class standardized the specification for both memory cards and devices in order to guarantee minimum writing speeds and deliver the best performance.
​

Speed Class Rating

The Speed Class Rating is the official unit of speed measurement for SD cards. The class number guarantees a minimum write speed as a multiple of 8 Mbit/s (1 MB/s). The SDA defines several speed class ratings, but manufacturers may claim conformance to those ratings without independent verification.

These are the ratings of all currently available cards:

Class 2 - 2 MB/s

Class 4 - 4 MB/s

Class 6 - 6 MB/s

Class 10 - 10 MB/s
​

What are the applications for Speed Class?

Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording

Class 4: MEPG-2 (HDTV) video recording, digital still camera (DSC) consecutive photo shooting

Class 6: Mega-pixel DSC consecutive photo shooting, professional video camera

Class 10: Full HD video recording, HD still picture consecutive shooting

SD Card Partitioning

What is SD partitioning?

SD Partitioning is the act of dividing a SD Card into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks. Partitions are also termed "slices" for operating systems based on BSD, Solaris or GNU Hurd. A partition editor software program can be used to create, resize, delete, and manipulate these partitions on the hard disk.
