What is flash and SSD recovery?
SSD (Solid State Drive) is a drive which has no moving parts such as in a conventional hard drive. For storage memory SSD uses flash memory. In simple words, it is such a big flash stick.
The main advantages of SSD drives is speed, resistance to mechanical damage, low power consumption.
High reading and recording speed – as compared to conventional hard disk drives SSD running at high speed. For example, the drive connected via SATAIII interface operates at 500 Mbps. It’s impressive but not the full potential of the SSD. The operating system is loaded on such drives in a matter of seconds.
Resistance to mechanical damage. SSD has no moving parts so it does not prone to mechanical damage, of course within reasonable limits.
Quiet operation. When using SSD drive does not emit any sounds. You probably know that regular hard drives during operation emit noise.
Low power consumption. In comparison to HDD, SSD uses less power that is very important for laptops.
Life span, this means that the SSD drive will run a limited time – usually 10,000 overwrite cycles. That is why they need SSD recovery pretty often.
Price. Yes, SSD drives is not very cheap, and SSD recovery is more expensive then that for HD.
Overall flash media devices are much more reliable than traditional hard drives, mainly due to the fact that they have no moving parts inside and this makes them less vulnerable to shocks and drops.
Most flash media manufacturers rate their devices at 10,000 to 100,000 write/erase cycles. With normal use, USB sticks, camera cards and SSD drives can last for up to a decade without showing signs of memory wear.
Typical reasons for Flash Media Failures:
- Electrical damage to microchips (power surges or electrostatic discharges)
- Damage from physical impacts (broken connectors or microchips)
- File corruption (usually due to unsafe device removal)
- Accidental file deletion or reformatting (human error)
- Damage from malicious software – viruses, trojan horses and other malicious programs
Data Recovery from failed flash media is usually performed by direct extraction of memory dumps from NAND microchips (professional data recovery tools being used) with subsequent reconstruction of logical volume. Sometimes damaged connector or electronic circuitry needs to be repaired.
