How long will data stay on a hard drive?
Data Retention Under those ideal conditions, hard drives are predicted to be able to retain their data for 9 to 20 years. The long range is due to the different architectures used in the manufacturing of modern hard drives. SSDs (Solid State Drives) have a reputation for having a very low data retention rate.
Which RAM retains information when power is off?
Non-volatile random-access memory (NVRAM) is random-access memory that retains its information when power is turned off (nonvolatile). This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied.
What type of RAM loses its data rapidly?
|when the power is turned off, both SRAM and DRAM lose all their data, and are therefore called||volatile memory|
|________ RAM loses its data rapidly, and the memory controller must refresh it several thousand times a second||Dynamic|
