SPI bus mode: Serial Peripheral Interface Bus is primarily used by embedded microcontrollers. This bus type supports only a 3.3-volt interface. This is the only bus type that does not require a host license.
Flash memory is a type of electronically erasable programmable read only memory (EEPROM), but may also be a standalone memory storage device such as a USB drive. EEPROM is a type of data memory device using an electronic device to erase or write digital data. Flash memory is a distinct type of EEPROM, which is programmed and erased in large blocks.
On April 22, 2002, veteran third party Nintendo console developer Factor 5 announced its 3D audio software development kit for GameCube developers, MusyX. In collaboration with Dolby Laboratories, it provides motion-based surround sound encoded as Dolby Pro Logic II.[32]
This card writes at a C4 speed (as indicated by the number 4 encircled by a C on the label). It’s a decent speed for smaller files, but considering a RAW photo files can be rather large, if you’re shooting high res, RAW files, this is not the card for you. It will absolutely freeze up your camera.

Unique to the GameCube is the controller’s prominent size and placement of the A button. Having been the primary action button in past Nintendo controller designs, it was given a larger size and more centralized placement for the GameCube. The rubberized analog stick in combination with the controller’s overall button orientation was intended to reduce the dreaded “Nintendo thumb” – a term used to describe pain in any part of the hands, wrists, forearms, and shoulders as a result of long-term play.[53][54]
NOR flash is more expensive to produce than NAND flash and tends to be used primarily in consumer and embedded devices for boot purposes and read-only applications for code storage. NAND flash is more suitable for data storage in consumer devices and enterprise server and storage systems due to its lower cost per bit to store data, greater density, and higher programming and erase (P/E) speeds.

Like the SanDisk, StarTech’s USB-C Dual UHS-II Card Reader supports UHS-II performance and does not have a microSD card slot. It’s much wider and longer than the competition, and it costs almost 2.5 times the price of the Verbatim for similar performance. It can read two SD cards simultaneously, although you lose some speed in the process.
The first Satechi Type-C SD and microSD Card Reader unit we tested did not recognize SD or microSD cards on three different Windows laptops. The second unit we tested read SD cards only with the “Satechi” logo facing down, and it read microSD cards only with the logo facing up. When it did work, it had slow SD and microSD speeds between 30 MB/s and 40 MB/s when they should have been about twice that.
Getting yourself in a memory card muddle and not sure which card to buy? We look at memory card speeds and the fastest memory card on the market to help explain the differences so you can find out what’s the best card for you.
On March 6, 2009, Pretec introduced the first SDXC card,[65] a 32 GB card with a read/write speed of 400 Mbit/s. But only early in 2010 did compatible host devices come onto the market, including Sony’s Handycam HDR-CX55V camcorder, Canon’s EOS 550D (also known as Rebel T2i) Digital SLR camera,[66] a USB card reader from Panasonic, and an integrated SDXC card reader from JMicron.[67] The earliest laptops to integrate SDXC card readers relied on a USB 2.0 bus, which does not have the bandwidth to support SDXC at full speed.[68]

Reliability Qualification results show that the projected data retention failure rate is much less than 1 PPM over 20 years at 85°C or 100 years at 25°C
The Secure Digital eXtended Capacity (SDXC) format, announced in January 2009 and defined in version 3.01 of the SD specification, supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification. SDXC adopts Microsoft’s exFAT file system as a mandatory feature.[15]
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.
Devices using flash memory erase data at the block level and rewrite data at the byte level — NOR flash — or multiple-byte page level — NAND flash. Flash memory is widely used for storage and data transfer in consumer devices, enterprise systems and industrial applications.
While EPROMs had to be completely erased before being rewritten, NAND-type flash memory may be written and read in blocks (or pages) which are generally much smaller than the entire device. NOR-type flash allows a single machine word (byte) to be written – to an erased location – or read independently.

Like the Unitek, the Iogear was fast and gave us the speeds we expected from each card. It had read and write speeds of 93 MB/s and 87 MB/s, respectively, during our SD card test, and read and write speeds of 93 MB/s and 73 MB/s during our microSD card test. In our CF card test, it had read and write speeds of 155 MB/s and 139 MB/s. It cannot read multiple cards at once, though.
I see 1-Star reviews being posted for this same card. Take the time to assure BEFORE you Click “Add to Cart” that your source is “SOLD BY SANDISK, FULFILLED BY AMAZON.” BUY FROM OTHER SOURCES AND YOU MAY GET BURNED*

Reliability and warranty: It’s vital that a card reader works the way it’s meant to. We tested a surprising number of units in this category that were defective or performed inconsistently. For this reason, we favor readers from trustworthy manufacturers with solid warranties—most USB-C card readers that we found had one-year warranties, but two- and three-year warranties are even better.
Store several gigabytes of data in a small form factor. Supports the latest in memory card format, SDXC (Secure Digital Extended Capacity). Provides two different memory card slots: whether you have the SD or MicroSD size memory card, the dual slot IOGEAR Card Reader/Writer has got you covered.
We appreciate your interest in the Nintendo GameCube.  At this time, we haven’t announced any immediate plans to discontinue the sale and distribution of this system, or the games available for it.  In fact, we still have a handful of software titles being developed for the Nintendo GameCube.  For the latest news and information on this system, as well as other Nintendo-related products, please keep an eye on the news section of our website (http://www.nintendo.com/newsmain?page=newsmain).

You can sometimes help increase the read speed of your card to your computer if you are using a USB 2 or FireWire accessory such as the Lexar UDMA Dual Slot (CF and SD) model or the SanDisk ImageMate Multi-Card USB 2.0 Reader.
The memory card market does sometimes seem overcomplicated, but if there’s one thing you need to remember from this article then it’s this: image quality is completely unaffected by your choice of memory card.
The most important features for an SD card reader are speed, physical size, and ease of use. Because most new laptops have at least one USB-C port—and some now have only USB-C ports—we focused on USB-C card readers for this guide. We also looked for readers that support both SD and CF cards to ensure compatibility with as many cameras as possible.
Same here, Dell Vostro…a couple of days ago I got an major update of the windows 10, not eaven asking for , took 1/2 day to update it and now my SD reader is not working and is not showing in Device Management, 
To erase a NOR flash cell (resetting it to the “1” state), a large voltage of the opposite polarity is applied between the CG and source terminal, pulling the electrons off the FG through quantum tunneling. Modern NOR flash memory chips are divided into erase segments (often called blocks or sectors). The erase operation can be performed only on a block-wise basis; all the cells in an erase segment must be erased together. Programming of NOR cells, however, generally can be performed one byte or word at a time.
Most NAND devices are shipped from the factory with some bad blocks. These are typically marked according to a specified bad block marking strategy. By allowing some bad blocks, the manufacturers achieve far higher yields than would be possible if all blocks had to be verified good. This significantly reduces NAND flash costs and only slightly decreases the storage capacity of the parts.
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.
