Storage technology

Rapid storage technology
Noah Data Strongroom is a modern, solid-state storage technique. This technique, known as flash memory by far surpasses the normal hard disc of today in efficiency, durability and reliability. The flash memory performs its work completely without moving parts

MLC and SLC
Only trade mark memory modules, especially selected and approved by Novega, come into operation for Noah Data Strongroom. Standardly MLC (Multi Level Cell) NAND memories are built in. Up to a memory dimension of 128 GB there can optionally be assembled SLC (Single Level Cell) modules. Flash memories based on SLC are particularly characterized by an even higher writing speed and an enhanced durability, but are a bit more expensive and not as compactly built as MLC memories. Hence SLC memories comparatively show a smaller capacity. We would be pleased to advise you on choice of memory technology convenient for you.

From Wikipedia:
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive interface, thus easily to be replaced in most applications. An SSD using SRAM or DRAM (instead of flash memory) is often called a RAM-drive, not to be confused with a RAM disk. The original usage of the term solid-state (from solid-state physics) refers to the use of semiconductor devices rather than electron tubes, but in this context, has been adopted to distinguish solid-state electronics from electromechanical devices as well. With no moving parts, solid-state drives are less fragile than hard disks and are also silent (unless a cooling fan is used); as there are no mechanical delays, they usually enjoy low access time and latency.
