What are the limitations of flash memory?
1. Limited Number of Rewrite Cycles: Flash memory has a finite number of rewrite cycles, typically ranging from 10,000-100,000 write cycles. After the memory has reached its rewrite limit, data can still be read from the device, but no new data can be written. 2. Security Risks: Unlike other forms of storage media, flash memory can be reprogrammed to rewrite or delete data quickly and easily. This means that important data stored in a flash memory device can be vulnerable to malicious attacks if left unsecured. 3. Fragmentation: When more and more data is written onto a flash memory device, it can experience fragmentation and decrease in performance. Fragmentation occurs when the data is broken up into smaller fragments scattered all over the drive, making it difficult to find and read the data. 4. Power Loss Issue: Power loss can cause serious damage to the electronic components of most flash memory devices since they are designed to be powered down quickly. This can lead to data corruption and even loss of data.
