Decent price, kept me updated with progress, well packed (and they chucked in some sweeties!) and good delivery. Great service overall.Read on Google
Today Flash memory is everywhere including our Smartphones and Tablets and Computers. With production costs falling, capacities ever expanding and the ability to stably and securely hold masses of data while being able read/write near instantaneously has led to the flash storage revolution.
What is Flash Storage?Flash memory is a type of non-volatile memory that doesn’t need any power to retain information - Even if the device has had no power for years the data within is safe. Based upon EPPROM (Electrically Erasable Programmable Read Only Memory) of yesteryear there are 2 main flash variants, NAND (Not And) and NOR (Not Or). NOR NOR is generally used for BIOS ROM utilised in things like Motherboards. It is perfect at executing code, has a high read speed and is very low power. It is also flawless in quality and contains little to no errors. NAND NAND on the other hand is permitted certain faults allowing for cheaper production. It also has a much higher write and erase speed making it perfect for storage applications. NAND is also very dense as the cells are connected in series which allows for much higher capacity storage. |
Are there different types of NAND?

USB Flash DrivesNAND Flash is perfect for all kinds of storage and USB Flash drives are no exception. These drives allow you to carry all sorts of data in a highly pocket friendly, compact form factor.

Memory CardsMemory cards are far harder to understand due to the multiple classes and versions available. The most widely used today is the SD card which comes in 3 sizes: Standard, Micro and Mini. These then come in 3 main capacity types SDSC (1MB - 2GB), SDHC (2GB – 32GB) and SDXC (32GB – 2 TB). On top of this there are speed classes which are suited to different applications. Ensure you buy a card that is compliant with your device for best operation: UHS SD UHS (Ultra High Speed) is designed for modern devices that need the very fastest write speeds. UHS can handle things like 4K video recording, Full HD Video, HD still images and continuous shooting.
SD SD are your everyday cards and will work with most generic devices. Class 10 is great for Full HD video recording and images as is a class 6 compliant card. Class 2 is designed for standard video recording and images.
