In most respects, the above types of flash memory cards differ from those used in enterprise storage. EMC is credited with being the first vendor to include SSDs in enterprise storage hardware when it added them to its Symmetrix disk arrays in 2008, spawning the advent of hybrid arrays that combine flash drives with a traditional spinning disk. Initially, enterprise SSDs in hybrid arrays were relegated for caching read data in flash due to their higher cost and lower endurance compared to HDDs.
If you’re an amateur photographer, or just starting out, chances are the most important factor in a memory card will be capacity. The capacity is measured in gigabytes(GB) and determines how much your card can hold. A higher capacity can help you if you’ll be taking photos on a trip and are unable to transfer them onto a computer, or if you will be taking high-definition photos to be used for print making.

When capturing images and videos with your camera, camcorder, drone, or select mobile device, you may need a memory card. Memory cards act as storage for your devices, capturing photographs or even 4K Ultra HD video. The more complex your images or videos — such as shooting burst photographs, fast action shots or high-definition videos — the faster and larger your memory card needs to be. When shopping for the right memory card, you’ll want to make sure it is compatible, and has the capacity and speed to support your device.
Nintendo began its marketing campaign with the catchphrase “The Nintendo Difference” at its E3 2001 reveal. The goal was to distinguish itself from the competition as an entertainment company. Later advertisements push the slogan, “Born to Play”, and video game commercials feature a rotating cube animation that morphs into a GameCube logo and ends with a voice whispering, “GameCube”. On May 21, 2001, the console’s launch price of $199 was announced- $100 lower than that of Sony’s PlayStation 2 and Microsoft’s Xbox.
Flash memory is used in enterprise server, storage and networking technology, as well as in a wide range of consumer devices, including USB flash drives, mobile phones, digital cameras, tablet computers, PC cards in notebook computers and embedded controllers. For instance, NAND flash-based solid-state drives are often used to accelerate the performance of I/O-intensive applications. NOR flash memory is often used to hold control code, such as the basic input/output system (BIOS), in a PC.
I bought this card for my Samsung Galaxy S II (T-Mobile T-989) and couldn’t be happier. I’ve got about 15 games, 10 apps, and 200+ songs on it and barely put a dent in it. The speed is also amazing…real fast. I work in a very dusty construction type environment in Michigan, outdoors, year-round, so the durability is also a nice plus. Water resistant (submersed) for up to 72 hrs and temp range of -13 to 185. Sandisk really got it right with this one.
In January 2009, the SDA announced the SDXC family, which supports cards up to 2 TB and speeds up to 300 MB/s. It features mandatory support for the exFAT filesystem.
I bought this flash drive so I could be able to put pictures onto my Surface Pro 3 without using a cord. Little did I realize that you can also use this flash drive to put your pictures off the camera and onto your phone as well! All you need is a adapter that allows you to put a flash drive to your phone. I am so happy I bought this because now I can have awesome photos on my phone without having to download them onto a computer then transferring them onto a phone.
MiniSD cards, the least frequently used format these days, measure 21.5 by 20 by 1.4 mm (HWD) and weigh just a gram, making them just over a third the volume and taking up just over half the area of a full-size SD card. Instead of cut corners, miniSD cards have a tapered corner to help you orient the card when putting it in a slot. This design aspect follows with the smallest of the SD cards, the microSD card.
A card’s read speed describes how fast data can be retrieved from a card. This performance is seen when transferring card contents to computers and printers for example. A faster read speed will transfer images to your computer more rapidly also (depending on how the SD card is wired up to the computer, as a direct connection vs USB 2 vs FireWire 800 vs USB 3 will make a significant difference also, as will, potentially, your hard disk or SSD storage memory speed).
Since late 2009, newer Apple computers with installed SD card readers have been able to boot in macOS from SD storage devices, when properly formatted to Mac OS Extended file format and the default partition table set to GUID Partition Table. (See Other file systems below).
Integrated USB connector – The SanDisk SD Plus product can be plugged directly into a USB port without needing a USB card reader. Other companies introduced comparable products, such as the Duo SD product of OCZ Technology and the 3 Way (microSDHC, SDHC, and USB) product of A-DATA, which was available in 2008 only.

If you are interested in an SD card for a DSLR, look at something like the Lexar Professional 600x 32GB SDHC UHS-I Flash Memory Card LSD32GCRBNA600. Since switching to the C10/U1 Lexar, I’ve been infinitely more happy with my camera. The Sandisk C4 32GB remains in my point and shoot, where it’s better suited.
Most SD cards are 2.1 mm (0.083 inches) thick, compared to 1.4 mm (0.055 inches) for MMCs. The SD specification defines a card called Thin SD with a thickness of 1.4 mm, but they occur only rarely, as the SDA went on to define even smaller form factors.
NOTE: As other buyers state, this item say’s Wii memory card on the packaging it comes in. This memory card is actually for a system called Nintendo GameCube. It does work on the Wii but only to save Nintendo Gamecube Games. If you’re looking for a Wii memory card for Wii games, that would an SD card you’re looking for.
Write speed is how fast images can be saved onto a memory card. This is a critical need, especially if your camera takes high-resolution images, burst pictures or HD video. If you have a slower memory card, you may have to wait for the memory card to finish writing before you can take additional shots, which could cause you to miss the perfect photo. If your card is too slow to properly handle video, it may cause dropped frames, inferior quality, or stop recording altogether. So if you’re doing sports photography, or taking video, make sure to look for a higher write speed.
In NOR flash, each cell has one end connected directly to ground, and the other end connected directly to a bit line. This arrangement is called “NOR flash” because it acts like a NOR gate: when one of the word lines (connected to the cell’s CG) is brought high, the corresponding storage transistor acts to pull the output bit line low. NOR flash continues to be the technology of choice for embedded applications requiring a discrete non-volatile memory device. The low read latencies characteristic of NOR devices allow for both direct code execution and data storage in a single memory product.
Secure Digital cards are ubiquitous in consumer electronic devices and have become the dominant means of storing several gigabytes of data in a small form factor. This device is extremely compact but big on compatibility within the SD memory card family. The unit supports the very latest in memory card format, SDXC (Secure Digital Extended Capacity).
In 1999, SanDisk, Matsushita, and Toshiba agreed to develop and market the Secure Digital (SD) Memory Card. The card was derived from the MultiMediaCard (MMC) and provided digital rights management based on the Secure Digital Music Initiative (SDMI) standard and for the time, a high memory density.

In 2005, Toshiba and SanDisk developed a NAND flash chip capable of storing 1 GB of data using multi-level cell (MLC) technology, capable of storing two bits of data per cell. In September 2005, Samsung Electronics announced that it had developed the world’s first 2 GB chip.
Speed class is a minimum sustained writing performance speed for SD cards. This means that it’s the speed it can write data to the card consistently. Speed class is mainly useful when you’re shopping for a card to use with video recording, since you’ll be continuously writing to the card. The higher the speed class, the more data you can write to the card in the same amount of time. Pay attention to this when deciding what card you need for the desired resolution you’d like to film in.

An SD Card (Secure Digital Card) is an ultra small flash memory card designed to provide high-capacity memory in a small size. SD cards are used in many small portable devices such as digital video camcorders, digital cameras, handheld computers, audio players and mobile phones. In use since 1999, SD Memory Cards are now available in capacities between 16 Megabytes and 1 Gigabyte. An SD card typically measures 32 x 24 x 2.1 mm and weighs approximately 2grams.
After researching all the USB-C SD readers available, we called in 12 models that met our requirements by accessories makers we trust. Then we plugged them into a 2016 MacBook Pro and a 2016 Dell XPS 13 and used AJA System Test and CrystalDiskMark to test their speeds with three SanDisk cards–one SD card, one microSD card, and one CF card.
Flash memory is extremely small, fast, lightweight, and makes no noise or have any moving parts, unlike hard drives. However, hard disks can hold considerably more data and its cost per megabyte is much cheaper although prices are quickly dropping as capacity grows larger for flash devices daily. Yet flash memory is quite reliable and allows you to specify which data you want to keep.
The SD card specification defines three physical sizes. The SD and SDHC families are available in all three sizes, but the SDXC family is not available in the mini size, and the SDIO family is not available in the micro size. Smaller cards are usable in larger slots through use of a passive adapter.
The Unitek is more intuitive to use than the other card readers we tested. It has an indicator light, so you can see when your card is connected or a transfer is underway with a glance. Plus, you don’t have to flip any of your memory cards upside down for the Unitek to identify them—like you do with the Iogear and Cable Matters—and all of the Unitek’s card slots feel sturdy and well-aligned. The company is also active in its Amazon reviews, so we’re optimistic that it will honor its two-year warranty and offer prompt customer support if you run into any issues.
