optical disc drive
over time, the performance gap between the central processing units (cpus) and electromechanical storage (hard disk drives and their raid setups) widened, requiring advancements in the secondary storage technology. a solution was found in flash memory, which is an electronic non-volatile computer storage media that can be electrically erased and reprogrammed. solid-state storage typically uses the nand type of flash memory, which may be written and read in chunks much smaller than the entire size of the storage device. the size of a minimal chunk (page) for read operations is much smaller than the minimal chunk size (block) for write/erase operations, resulting in an undesirable phenomenon called write amplification that limits the random write performance and write endurance of flash-based solid-state storage devices. another type of solid-state storage devices uses volatile random-access memory (ram) combined with a battery that allows the contents of ram to be preserved for a limited amount of time after the device's power supply is interrupted. as an advantage, ram-based solid-state storage is much faster compared to flash, and does not experience write amplification.

bring your own operating system









































bring your own operating system (byoos) relates to the practice of providing pc computers, usually without internally installed disks, so users can bring their own operating system (commonly on usb pen drives) and use the supplied hardware with the operating system of their choice.









































byoos has been made possible thanks to the ability to create usb pen drives and other external storage devices with 'live' operating system images containing all the necessary drivers to allow boot up and operation on any compatible computer.
