Why do SSDs drop? How should I achieve data recovery after falling off? These questions have actually been asked since the birth of the SSD, after all, compared to the mechanical hard disk, based on the unique storage mechanism of the SSD, it is difficult to recover data after the hard disk failure.
A few days ago, a Japanese company called DDS (Digital Data Solution Company) made an introduction in an interview a few days ago, the company ranked first in the Japanese data recovery market for 11 consecutive years, the recovery rate is as high as 95.2%, SSD hard disk data recovery is also the company's core technology.
SSD is more difficult than HDD hard disk to recover data mainly for two reasons, the first is that SSD failure is difficult to find the cause, unlike HDD hard disk can be visual scratches, head position or sound to judge.
Secondly, due to the unique principle of SSD hard disk, in order to prevent the deterioration of flash memory performance, the write location needs to change continuously, and 80% of SSD failures are related to firmware corruption, so it is impossible to accurately know the location of the written data.
These two reasons lead to SSD hard disk damage after it is difficult to recover data, but DDS company has a deep accumulation, other companies can not solve the problem, will also find them shot, but how they recover data is the company secret.
For SSD failure, DDS experts said that now the SSD hard disk capacity is getting larger and larger, but increasing the density will also reduce the quality, more prone to errors, in order to stabilize the use, he recommends choosing the SLC flash drive.
