SANDISK MEMORY VAULT TECHNOLOGY
As a leader in flash memory technology development, SanDisk has been in the forefront of developing advanced memory technology for over 20 years. For the SanDisk Memory Vault, SanDisk engineers have built on this success to create an archival storage device with the capability for long term data preservation.
Data Retention Test Methodology
In order to have quantifiable data to show how this device can support up to 100 years of data retention, accelerated temperature cycling and the Arrhenius acceleration factor was used to simulate the effects on data retention over long durations of memory usage.The Arrhenius equation expresses the relationship between the rate constant (or acceleration factor) and the activation energy and temperature of a reaction.
For the purposes of the data retention test for the SanDisk Memory Vault, the following temperatures and activation energies were used:
Boltzmann Constant = 8.62*10-5
Product application temperature used for this test (Ta) = 40ºC
Product test temperature used for this test (Tt) = 125ºC
Product's time-to-failure is exponentialArrhenius Acceleration Factor = 2721
The activation energy used in these calculations is a conservative value of well-known industry standard numbers. Additionally, higher stress was introduced on the product by taking a conservative assumption of 40ºC application temperature in the model, which is higher than the typical archival storage temperature of 25°C +/- 10°C.
After capturing your most precious moments, whether they're graduation photographs or wedding videos, have the peace of mind that they will be stored in their original format for generations to come. Extensive data retention test results and over 20 years of memory management experience show that you can trust SanDisk to deliver the solutions to preserve your memories.
