To compare speed specifications in data sheets of NAND flash memory media, the test conditions must be identical. If the measurement was not started repeatedly or did not cover the entire logical address space, the specified speed can be significantly higher than the real achievable speed.
When qualifying a NAND flash memory medium for performance or timecritical applications, it is advisable to simulate
the maximum load peaks and access patterns of the application as well as possible in a test program and to test this over a longer period of time.
