The ReadyBoost cache is created on the root directory of the drive. If the system drive (the primary drive, with Windows system files on it) is a solid-state drive (SSD), ReadyBoost is disabled, since reading from that drive would be at least as fast as reading from the ReadyBoost drive. [7]
ReadyBoost (when enabled) uses external memory like a USB flash drive to extend the system cache beyond the amount of RAM installed in the computer. ReadyBoost also has a component called ReadyBoot that replaces the Prefetcher for the boot process if the system has 700 MB or more of RAM.
The small discs are more expensive than the standard size, and do not work in all drives. Universal Disk Format (UDF) version 1.50 and above has facilities to support rewritable discs like sparing tables and virtual allocation tables , spreading usage over the entire surface of a disc and maximising life, but many older operating systems do not ...
It is designed to leverage features introduced in Windows Vista, namely ReadyBoost (a supplementation of RAM-based disk caching by dedicated files on flash drives, except on the 512 MB version) and/or ReadyDrive (a non-volatile caching solution, i.e. an implementation of a hybrid drive, as long as the main storage isn't already one); [5] as ...
Suggesting initramfs was an alternative to ReadyBoost is incorrect: they are entirely different things. Initramfs is a system which is only of relevance during the booting of the machine and allows you to have a smaller runtime kernel during operation (improved boot times as a result of a sequential read are consequential rather than by design).
By default, the necessary files are loaded into main memory, but using a feature called ReadyBoost, Windows Vista and Windows 7 can use alternative storage such as USB flash drives, thereby freeing up main memory. Although hard disks may have higher sequential data transfer rates, flash drives can be faster for small files or non-sequential I/O ...
CompactFlash IDE (ATA) emulation speed is usually specified in "x" ratings, e.g. 8x, 20x, 133x. This is the same system used for CD-ROMs and indicates the maximum transfer rate in the form of a multiplier based on the original audio CD data transfer rate, which is 150 kB/s.
