I bought this during black friday and I got a huge discount using my rewards points also. I primarlly use it for my Galaxy Note 2. After 2 months, the phone says that the sd card was unexpectedly unmouted. Then my card was not recognized and blank. I could not reformat it in any way since my computer and any other devices can not recognize it. After a successfull fix, 2 days later same thing happen and now I can not get it to work at all. I do not know who to get a hold on to get this fixed. But it is a bummer since I it is a nice size and value. But it just failed horribly.

If your smartphone, tablet or entry-level point-and-shoot camera has a memory card slot, you may opt to add a memory card to store your photos, videos, and other data like apps or music. In these cases, you will be more concerned about the card’s storage capacity than its speed. Though they are small, microSD cards can offer large capacities of 128GB and more. Whichever size card you’re interested in, you’ll want to make sure before you buy that your device will support that capacity.
Two major flash device manufacturers, Toshiba and Samsung, have chosen to use an interface of their own design known as Toggle Mode (and now Toggle V2.0). This interface isn’t pin-to-pin compatible with the ONFI specification. The result is a product designed for one vendor’s devices may not be able to use another vendor’s devices.[46]
The SanDisk Standard SD memory card has a blank writeable white space on the front of the card, making it easy to identify your different cards. Use one memory card for all your vacation photos, and another for all your favorite music–the label makes it easy to see which is which at a glance. Rather than inserting cards into your digital device to review the content, simply look at the label and go.
The method used to read NAND flash memory can cause nearby cells in the same memory block to change over time (become programmed). This is known as read disturb. The threshold number of reads is generally in the hundreds of thousands of reads between intervening erase operations. If reading continually from one cell, that cell will not fail but rather one of the surrounding cells on a subsequent read. To avoid the read disturb problem the flash controller will typically count the total number of reads to a block since the last erase. When the count exceeds a target limit, the affected block is copied over to a new block, erased, then released to the block pool. The original block is as good as new after the erase. If the flash controller does not intervene in time, however, a read disturb error will occur with possible data loss if the errors are too numerous to correct with an error-correcting code.[30][31][32]

UHS-II uses an additional row of pins to transfer data faster than UHS-I. Because of that extra row of physical pins, you can use a UHS-II card with a UHS-I camera, and a UHS-I card with a UHS-II camera, but you won’t get UHS-II speeds unless both camera and card support it. Likewise, to get those transfer speeds from your SD card to your computer, both the card and card reader must support it. Only high-end cameras can take advantage of UHS-II SD cards right now, but we expect this to change. In February 2017, the SD Association also introduced UHS-III (PDF) to provide further support for 360-degree, 3D, 4K, and 8K media content, but we expect it will take a year or two before we see memory cards and devices that support the new interface.
NOR memory has an external address bus for reading and programming. For NOR memory, reading and programming are random-access, and unlocking and erasing are block-wise. For NAND memory, reading and programming are page-wise, and unlocking and erasing are block-wise.
Version 5.0 was announced in February 2016 at CP+ 2016, and added “Video Speed Class” ratings for UHS cards to handle higher resolution video formats like 8K.[17][18] The new ratings define a minimum write speed of 90 MB/s.[19][20]
Some consumer-grade flash memory cards are used by companies to cache reads and writes with hybrid flash storage. Enterprise MLC is an MLC NAND variant with enhanced write cycles compared to consumer-grade MLC. Some newer enterprise SSDs use triple-level cell NAND flash, which stores three data bits per each flash cell. SSDs made with 3D NAND represent the next evolution. IBM, Samsung and Toshiba produce and market SSDs with 3D NAND, in which flash memory cells are stacked atop one another in vertical layers.
The specific commands used to lock, unlock, program, or erase NOR memories differ for each manufacturer. To avoid needing unique driver software for every device made, special Common Flash Memory Interface (CFI) commands allow the device to identify itself and its critical operating parameters.
The GameCube is the first Nintendo console to use optical discs as its primary storage medium. The discs are similar to the miniDVD format; as a result of their smaller size and the console’s small disc compartment, the system was not designed to play standard DVDs or audio CDs. The console supports online gaming for a small number of games via the broadband or modem adapter and connects to the Game Boy Advance via the link cable, allowing players to access exclusive in-game features using the handheld as a second screen and controller.
Unlike our other picks, the IOGear lacks an indicator light, so you can’t see when your card is connected or a transfer is underway at a glance. We also found that the SD card slot was a bit too shallow. The IOGear reader is slightly bigger than our other USB-C picks, but it has the best warranty of its competitors, covering three years.
It takes up the most space of all our picks, measuring 3.5 by 2 by 0.6 inches, and it weighs 4 ounces. The Kingston card reader isn’t terrible to look at, despite the loud red-and-white design on its top (including a large, red “Kingston” logo that doubles as an indicator light), but it isn’t as attractive as other readers we tested. It comes bundled with a removable, 43-inch connecting cable. None of the other readers we tested had a cable that was this long, or removable.
The write endurance of SLC floating-gate NOR flash is typically equal to or greater than that of NAND flash, while MLC NOR and NAND flash have similar endurance capabilities. Examples of endurance cycle ratings listed in datasheets for NAND and NOR flash, as well as in storage devices using flash memory, are provided.[51]
When you plug it in, the clear LED lights up as a bright blue – something you may wish to cover with a piece of scotch tape if bright blue lights at night bother you! When you’re reading or copying files to the SD card, the little blue light on top blinks to indicate data activity.
Multiple chips are often arrayed to achieve higher capacities[59] for use in consumer electronic devices such as multimedia players or GPSs. The capacity of flash chips generally follows Moore’s Law because they are manufactured with many of the same integrated circuits techniques and equipment.
SD card speed is customarily rated by its sequential read or write speed. The sequential performance aspect is the most relevant for storing and retrieving large files (relative to block sizes internal to the flash memory), such as images and multimedia. Small data (such as file names, sizes and timestamps) falls under the much lower speed limit of random access, which can be the limiting factor in some use cases.[35][36][37]
Many of Nintendo’s own first-party games, such as Super Smash Bros. Melee and Mario Kart: Double Dash‼, saw strong sales, though this did not typically benefit third-party developers or directly drive sales of their games. Many cross-platform games — such as sports franchises released by Electronic Arts — were sold in numbers far below their PlayStation 2 and Xbox counterparts, eventually prompting some developers to scale back or completely cease support for the GameCube. Exceptions include Sega’s family friendly Sonic Adventure 2 and Super Monkey Ball, which reportedly yielded more sales on GameCube than most of the company’s games on the PlayStation 2 and Xbox.[20] After several years of losing money from developing for Nintendo’s console, Eidos Interactive announced in September 2003 that it would end support for the GameCube, canceling several games that were in development.[87] Later, however, Eidos resumed development[88] of GameCube games, releasing hit games such as Lego Star Wars: The Video Game and Tomb Raider: Legend. In addition, several third-party games originally intended to be GameCube exclusives – most notably Resident Evil 4 – were eventually ported to other systems in an attempt to maximize profits following lackluster sales of the original GameCube versions.

With the GameCube, Nintendo failed to reclaim the market share lost by its predecessor, the Nintendo 64. Throughout the lifespan of its console generation, GameCube hardware sales remained far behind its direct competitor the PlayStation 2, and slightly behind Microsoft’s Xbox. The console’s “family-friendly” appeal and lack of support from certain third-party developers skewed the GameCube toward a younger market, which was a minority demographic of the gaming population during the sixth generation.[96] Many third-party games popular with teenagers or adults, such as the blockbuster Grand Theft Auto series and several key first-person shooters, skipped the GameCube entirely in favor of the PlayStation 2 and Xbox.
Today’s digital cameras take increasingly high quality photos, so there is a greater need for storage space to store these high-resolution files. The SanDisk Standard memory cards come in capacities of up to 32 GB1, allowing you to take plenty of photos without running out of space. With the Standard SD memory card, you won’t miss those special moments like a baby’s first steps, a child’s first dance recital, or a treasured vacation moment.
NAND flash uses tunnel injection for writing and tunnel release for erasing. NAND flash memory forms the core of the removable USB storage devices known as USB flash drives, as well as most memory card formats and solid-state drives available today.
The SD/MicroSD/MMC Card Reader/Writer is a solution for hi-speed, bi-directional image and data transfer. Images and data can be transferred quickly from Secure Digital Card (SD), MultiMedia Card (MMC), or MicroSD memory cards to PCs or Macs. This is particularly useful in many applications, including digital cameras, video cameras, mobile phones, MP3, and other mobile devices. This item is an ideal way to bridge the gap between your desktop computer and other CE products.
The SD protocol envisioned the ability to gang 30 cards together without separate chip select lines. The host device would broadcast commands to all cards and identify the card to respond to the command using its unique serial number.[citation needed]
The most important advice[according to whom?] to consumers is to continue to match SD card purchases to an application’s recommended speed class. Applications that require a specific speed class usually specify this in their user manuals.
If you’re planning to store photos and videos on your memory card, you may need to consider write speed as well as capacity. If your photography needs are fairly basic, such as taking clear, quality pictures of family vacations or get-togethers, any average memory card, like a Speed Class 10, should provide sufficient speed and reliability. However, if you plan on taking video including 4K Ultra HD or HRD, you’ll require faster speed and more capacity.
If you use a camera or cards that support faster UHS-II speeds, the Verbatim USB-C Pocket Card Reader is the reader you should buy. The Verbatim’s SD and microSD slots performed reliably and speedily—around 2.5 times faster than our top pick in our SD card read and write tests—and it has a slimmer design than most of the competition. Because of its very short cord, there’s no way to lay the device completely flat during data transfer, although you can neatly store the cord underneath the bottom of the reader when it’s not in use. It also lacks a CF slot and the handy indicator light that most of our other picks have. It comes with a one-year warranty.
In addition to flash memory arrays, the ability to insert SSDs in x86-based servers has increased the technology’s popularity. This arrangement is known as server-side flash memory and it enables companies to sidestep the vendor lock-in associated with purchasing expensive and integrated flash storage arrays.
If our pick is sold out or unavailable, the Iogear USB-C 3-Slot Card Reader is a good second choice. Like our top pick, the Iogear delivers fast speeds with SD, microSD, and CF cards, although it can read only one card at a time. The Iogear is a little longer than the Unitek, but it’s thinner and lighter, with a shorter connecting cable. It lacks an indicator light, though, and its slots weren’t as easy to use as the Unitek’s. Using the Iogear’s CF card slot, in particular, isn’t intuitive. We spent 30 seconds trying to fit the CF card into its slot—risking damage to the card and the slot—before realizing that it had to be inserted upside down relative to the logo and the other slots. The Unitek’s slots, on the other hand, recognized every card right-side up. The Iogear comes with a three-year warranty, longer than that of any of its competition.
After researching nearly 50 card readers and testing 15 over the past year, we found that the Unitek USB-C Card Reader is the best option for anyone who needs an SD card reader for a new laptop with USB-C ports. The Unitek delivered fast, consistent speeds in a compact, easy-to-use package, and it supports SD, microSD, and CF cards.
Also in early 2010, commercial SDXC cards appeared from Toshiba (64 GB),[69][70] Panasonic (64 GB and 48 GB),[71] and SanDisk (64 GB).[72] In early 2011, Centon Electronics, Inc. (64 GB and 128 GB) and Lexar (128 GB) began shipping SDXC cards rated at Speed Class 10.[73] Pretec offered cards from 8 GB to 128 GB rated at Speed Class 16.[74]
Works very well for a third party GC memory card. Used it for about a week and not a single game file has corrupted. If you’re looking for a 1019 block GC memory card but don’t want to shell out the $20, this is what you’re looking for.

The adapter works to import image files to the iOS Photos app. I’m running iOS 9.2 on an iPhone 6 Plus and iPad Pro. The transfer speed on the iPad Pro is faste The adapter works to import image files to the iOS Photos app. I’m running iOS 9.2 on an iPhone 6 Plus and iPad Pro. The transfer speed on the iPad Pro is faster, rated at USB 3.0 speeds as opposed to the iPhone’s USB 2.0 speed. I transferred a Nikon D800 RAW file, which are huge 36 megapixel files, in about 2 seconds on the iPad and roughly 5 seconds on the iPhone. If you’re working with RAW files, make sure your camera model is supported by iOS. Once the files are transferred to your Photos app, you will still need an app to convert the RAW files to file types compatible with the photo editor apps you use. Most will convert to JPG at this time. I’m using the piRAWnha app but there are others. Even the current Adobe apps for iOS will only work with JPG files—Lightroom and Photoshop Fix are the two I tested. More(Read full review)
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.[61]
I am using this memory card for saving Gamecube games on my softmodded Wii. I am USB loading the games with Dios-Mios. That being said, I doubt that it is my application that is causing this card to fail because it has a very difficult time recognizing the card even in the Wii data options.
