![]() For the high-end performance segment, Dataram now offers 8GB DIMMs for PCs enabling a powerful 32GB PC configuration. With popular PC’s have 4 DIMM slots and 4GB capacity DIMMs widely available, 16GB PC’s are common–as are RAMDisk sizes ranging from 4GB up to 12GB becoming mainstream. Dataram’s RAMDisk has the option of saving the data on system shutdown, and having it re-created on the RAMDisk when the system reboots.Īs the price of RAM has dropped significantly over the past few years, RAMDisk software has been gaining in popularity as a high speed affordable performance enhancement. In many cases, the data stored on the RAM disk has been moved for faster access from data permanently stored elsewhere. ![]() This is sometimes desirable: for example, when working with a decrypted copy of an encrypted file, or for storing a web cache (doing this on a RAM disk can also improve the speed of loading pages). RAM disk can access data with only the memory address of a given file, with no movement, alignment or positioning necessary.īecause the storage is in RAM, it is volatile memory, which means the data will be lost in the event of power loss, whether intentional (computer reboot or shutdown) or accidental (power failure). A physical hard drive or optical media, such as CD-ROM, DVD, and Blu-ray must move a head or optical eye into position and a tape drive must wind or rewind to a particular position on the media before reading or writing can occur. This performance gain is due to multiple factors, including access time, maximum throughput, type of file system, and other factors as well.įile access time is greatly decreased since a RAM disk is solid state (no mechanical parts). The performance of a RAM disk in general, is orders of magnitude faster than other forms of storage media, such as an SSD (up to 100X) and hard drive (up to 200X). It is sometimes referred to as a “virtual RAM drive” or “software RAM drive” to distinguish it from a “hardware RAM drive” which is a type of solid-state drive. The computer uses this block of memory as a disk drive (secondary storage). ![]() ~written by Nelson Rodriguez, Dataram Memory Blog Team MemberĪ RAM disk, or RAM drive is software that creates a block of main memory made up of DRAM chips on DIMM modules (volatile memory) to unlock the full potential of your available system RAM.
