disk!media!solid state This is a relatively recent addition to the available technology and has been made popular especially in portable computers as well as in embedded systems. The most popular type is flash RAM, but also other types of RAM is used. A few years ago many had great hopes for magnetic bubble memories but it turned out to be relatively expensive and is not that common. In general the use of RAM disks are regarded as a bad idea as it is normally more sensible to add more RAM to the motherboard and let the operating system divide the memory pool into buffers, cache, program and data areas. Only in very special cases, such as real time systems with short time disks be a sensible solution. Flash RAM is today available in several 10’s of megabytes in storage and one might be tempted to use it for fast, temporary storage in a computer. There is however a huge snag with this: flash RAM has a finite life time in terms of the number of times you can rewrite data, so putting swap, /tmp or /var/tmp on such a device will certainly shorten its lifetime dramatically. Instead, using flash RAM for directories that are read often but rarely written to, will be a big performance win. In order to get the optimum life time https://besthookupwebsites.org/badoo-review/ out of flash RAM you will need to use special drivers that will use the RAM evenly and minimize the number of block erases. This example illustrates the advantages of splitting up your directory structure over several devices. Solid state drives have no real cylinder/head/sector addressing but for compatibility reasons this is simulated by the driver to give a uniform interface to the operating system. Lire la suite
