512gb micro sd card | sandisk ultra vs sandisk extreme

These are SD memory cards but with a higher capacity. Original SD cards only went up to 2GB, so SDHC was invented with a maximum capacity of 32GB. They are identical in shape and size, but they are different media types. Though your camera may fit a SDHC, be careful because if the camera was made before SDHC came along it may not recognise it.
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.
Besides its use as random-access ROM, NOR flash can also be used as a storage device, by taking advantage of random-access programming. Some devices offer read-while-write functionality so that code continues to execute even while a program or erase operation is occurring in the background. For sequential data writes, NOR flash chips typically have slow write speeds, compared with NAND flash.

We thought about the developers as our main customers. In particular for GameCube, we spent three years working with Nintendo of America and with all sorts of developers, trying to understand the challenges, needs, and problems they face. First among these is the rising cost of development. The GameCube can see high performance without too much trouble; it isn’t a quirky design, but a very clean one. It was important we didn’t require jumping through hoops for high performance to be achieved. On top of that, it is rich in features, and we worked to include a dream group of technical features that developers requested.

A new generation of memory card formats, including RS-MMC, miniSD and microSD, feature extremely small form factors. For example, the microSD card has an area of just over 1.5 cm2, with a thickness of less than 1 mm. As of August 2017 microSD cards with capacity up to 400GB are available.[11][12]
If our pick is out of stock or unavailable, we recommend the Iogear USB-C 3-Slot Card Reader. It was fast and reliable in all of our tests, it supports SD, microSD, and CF cards, and it’s slim and light. But it lacks an indicator light, it’s less intuitive to use, and it’s usually a little more expensive than our top pick, the Unitek. Iogear includes a three-year warranty, longer than that of any of its competitors.
Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks. A block stored on a flash memory chip must be erased before data can be written or programmed to the microchip. Flash memory retains data for an extended period of time, regardless of whether a flash-equipped device is powered on or off.

xD Picture cards (standing for ‘eXtreme Digital’) are a Fujifilm format used in some (older) Fuji and Olympus cameras, although these brands are now routinely compatible with more standard SD/SDHC technology.

The next step is to form a cylindrical hole through these layers. In practice, a 128 Gibit V-NAND chip with 24 layers of memory cells requires about 2.9 billion such holes. Next the hole’s inner surface receives multiple coatings, first silicon dioxide, then silicon nitride, then a second layer of silicon dioxide. Finally, the hole is filled with conducting (doped) polysilicon.[24]
Like other types of flash memory card, an SD card of any SD family is a block-addressable storage device, in which the host device can read or write fixed-size blocks by specifying their block number.[citation needed]
A malfunctioning SD card can be repaired using specialized equipment, as long as the middle part, containing the flash storage, is not physically damaged. The controller can in this way be circumvented.[120][121]
Interesting that you mention it’s not compatible with Windows 10. I’m looking for a new SD/CF card reader because my Lexar reader (the one previously recommended here) keeps connecting and disconnecting from my new Windows 10 desktop. Fortunately, it doesn’t do that when reading a card. Your post makes me wonder if Lexar readers have an issue with Win 10.

Early on in its history, Nintendo had achieved considerable success with third-party developer support on the Nintendo Entertainment System (NES) and Super NES (SNES). Competition from the Sega Genesis and Sony’s PlayStation in the 1990s changed the market’s landscape, however, and reduced Nintendo’s ability to obtain exclusive, third-party support on the Nintendo 64 (N64). The console’s cartridge-based media was also increasing the cost to manufacture software, as opposed to the cheaper, higher-capacity optical discs used by the PlayStation.[61][62]
A SDIO (Secure Digital Input Output) card is an extension of the SD specification to cover I/O functions. SDIO cards are only fully functional in host devices designed to support their input-output functions (typically PDAs like the Palm Treo, but occasionally laptops or mobile phones). These devices 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.
Windows Phone 8 devices use SD cards designed for access only by the phone manufacturer or mobile provider. An SD card inserted into the phone underneath the battery compartment becomes locked “to the phone with an automatically generated key” so that “the SD card cannot be read by another phone, device, or PC”.[45] Symbian devices, however, are some of the few that can perform the necessary low-level format operations on locked SD cards. It is therefore possible to use a device such as the Nokia N8 to reformat the card for subsequent use in other devices.[46]
But before you take things into 6th gear; is your camera capable of the fastest speed out there? Probably not. The turbo speeds out there (such as Class 10 cards) are usually aimed at video cameras producing movies which need to write as much data as possible every second. You need to make sure your camera can utilise all the speed your card can deliver, if not it goes to waste and so will your money. Consult your instruction manual or search the manufacturer’s website for the fastest card speed supported.

Windows Vista (SP1) and later[21] and OS X (10.6.5 and later) support exFAT out of the box.[22][23] (Windows XP and Server 2003 can support exFAT via an optional update from Microsoft.)[24] Most BSD and Linux distributions do not, for legal reasons; users must manually install third-party implementations of exFAT (as a FUSE module) in order to be able to mount exFAT-formatted volumes.[25] However, SDXC cards can be reformatted to use any file system (such as ext2, UFS, or VFAT), alleviating the restrictions associated with exFAT availability.
UHS-II standard SDHC/SDXC cards were recently released by Sandisk and aim to offer quicker transfer rates, increasing write speeds up to 250MB/s or faster. The Sandisk Extreme Pro cards match up with the sheer amount of data streaming through the camera’s buffer when shooting lots of Raw files or high quality HD movies. Prices can range between around £50-£150 depending on the capacity (currently 16-64GB).
Although Tripp Lite’s USB 3.1 USB-C Multi-Drive Flash Memory Media Reader has similar speeds to the Unitek, its microSD port suffers from the same misalignment as the one on our runner-up pick, it’s missing an indicator light, and it costs nearly twice as much as the Unitek.
NAND devices also require bad block management by the device driver software, or by a separate controller chip. SD cards, for example, include controller circuitry to perform bad block management and wear leveling. When a logical block is accessed by high-level software, it is mapped to a physical block by the device driver or controller. A number of blocks on the flash chip may be set aside for storing mapping tables to deal with bad blocks, or the system may simply check each block at power-up to create a bad block map in RAM. The overall memory capacity gradually shrinks as more blocks are marked as bad.
The first thing to consider when getting a memory card is where you’re going to use it. Different cameras, camcorders, and smartphones use different sizes of card, and while you can start with the smallest and use adapters to work your way up, it’s generally best to use the card size intended for the device.
On the top of the controller are two “pressure-sensitive” trigger buttons marked “L” and “R”. Each essentially provides two functions: one analog and one digital. As the trigger is depressed, it emits an analog signal which increases the more it is pressed in. Once fully depressed, the trigger “clicks” registering a digital signal that can be used for a separate function within a game. There is also a purple, digital button on the right side marked “Z”.[52]
Another limitation is that flash memory has a finite number of program – erase cycles (typically written as P/E cycles). Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles before the wear begins to deteriorate the integrity of the storage.[25] Micron Technology and Sun Microsystems announced an SLC NAND flash memory chip rated for 1,000,000 P/E cycles on 17 December 2008.[26]
Official pin numbers for each card type (top to bottom): MMC, SD, miniSD, microSD. This shows the evolution from the older MMC, on which SD is based. NOTE: This drawing doesn’t show 8 new UHS-II contacts that were added in spec 4.0.
Flash memory (both NOR and NAND types) was invented by Fujio Masuoka while working for Toshiba circa 1980.[4][5] According to Toshiba, the name “flash” was suggested by Masuoka’s colleague, Shōji Ariizumi, because the erasure process of the memory contents reminded him of the flash of a camera.[6] Masuoka and colleagues presented the invention at the IEEE 1987 International Electron Devices Meeting (IEDM) held in San Francisco.[7]
For the first 6 months, things seemed to work fine. Files were copied successfully, no corruption issues occurred. The only interesting thing is that the SD card reader would get very hot to the touch – even when doing nothing! (In comparison, the Transcend USB 3.0 reader does get pretty warm as well, but only when data is actually being transferred.)
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.

Most flash ICs come in ball grid array (BGA) packages, and even the ones that do not are often mounted on a PCB next to other BGA packages. After PCB Assembly, boards with BGA packages are often X-rayed to see if the balls are making proper connections to the proper pad, or if the BGA needs rework. These X-rays can erase programmed bits in a flash chip (convert programmed “0” bits into erased “1” bits). Erased bits (“1” bits) are not affected by X-rays.[33][34]
2) I put it in the camera, and the Nikon D40 immediately formatted the card and it was ready for use. The information screen said that it was ready to hold 2.2K (2200) pictures. I held down the shutter in continuous mode, and fired off about 20 seconds of pictures (the D40 shoots somewhere around 3 or 3.3 pics per second in burst mode). There was no stutter, lag, etc. when writing to the card. This SDHC card (remember different format than SD, which was the format available when I bought the camera) worked flawlessly in this little test. I buy only SanDisk or Lexar products, and I can say that media from neither company has ever let me down. The two Lexar cards have stored downloaded and erased around 72K pictures over six years, generally at 300-500 pics per download/erase/format cycle and are still going strong with the original capacity intact.
They still have gamecubes here in my small city, I’d love to hear that they get more wii’s (I have one). My friend that works there says employees are allowed to reserve them, I only got mine cause they forgot to hold the consoles this shipment. 
Antony Adshead, a storage editor with Computer Weekly, explains the basics of flash storage technology and offers a rundown of MLC, eMLC, SLC and TLC flash, commenting on their place in the market and the use cases they are suited to.
Specified in version 4.0, further raises the data transfer rate to a theoretical maximum of 156 MB/s (full duplex) or 312 MB/s (half duplex) using an additional row of pins[31][32] (a total of 17 pins for full-size and 16 pins for micro-size cards).[27]
SanDisk Standard SD cards give you plenty of room to capture and store all your precious photos, safely and securely. Fast, and built to last, you can count on SanDisk Standard SD cards to be ready when you are, every day.

NAND sacrifices the random-access and execute-in-place advantages of NOR. NAND is best suited to systems requiring high capacity data storage. It offers higher densities, larger capacities, and lower cost. It has faster erases, sequential writes, and sequential reads.
Bad block management is a relatively new feature in NOR chips. In older NOR devices not supporting bad block management, the software or device driver controlling the memory chip must correct for blocks that wear out, or the device will cease to work reliably.
