Recovery and writing data to SSD: Working towards a standard
Set up a new working group that will seek to promote co-operation between manufacturers and SSD data recovery companies to streamline and make less burdensome recovery and cancellation data from solid-state devices.
The solid-state storage solutions presents some problems when the need arises to recover data after a crash, accidental or malicious it. At the Flash Memory Summit last week, the Storage Networking Industry Association (SNIA) and the Solid-State Storage Initiative (SSSI) announced the establishment of a new Special Interest Group that will evaluate the technical recovery and data delete from solid-state media to fuel the development of tools and operating standards.
The companies involved to recover data from damaged entertained comparisons with SSD manufacturers for several years. ” The problem is that there are no standards for these procedures, ” said the president of the newly formed Data Recovery / Erase SIG, Scott Holewinski, who observed as an annual session at the Summit is not enough to eviscerate the problem and that the purpose of the GIS should be to be able to bring together all stakeholders to improve the collection procedures and withdrawn from, solid-state storage. Even practices erasure are considered, since they require the same technical capabilities of the recovery operations.
The main problem when it has to do with the SSD is represented by all the series of functions that have been introduced by various manufacturers over the years to extend the life of solid-state disks over time. The wear-leveling algorithms do nothing but move very frequently the data from cell to the memory cell, from chip to chip with the outcome of making difficult for the recovery of specific information. Added to this are the technologies of self-encrypting that put further to the test data recovery techniques, many of which are developed in proprietary companies that deal with these activities. ” There are few passable roads. Less than get help from manufacturers, there is very little you can do to recover the information. ”
The first objective of the SIG aims to achieve is to build a business case to show the existence of a market for the recovery and write data, so as to convince the producers of the various drives to commit engineering resources on this aspect. You can try to work with standardization bodies. The ultimate goal is to be able to create a scenario where it is possible to simplify the recovery and write data to the dedicated SSD.
Holewinski was keen to stress that the techniques developed for the retrieval of information and data from SSD will not be based on mechanisms to bypass security measures or authentication as in the vast majority of the time is the impairment (physical or logical) of the data structure which prevents their recovery.
The operations of data recovery from SSD for now remain a practice very expensive, especially compared to what you can with a floppy / traditional mechanical: often every single striding / case is unique and difficult due to macro-categories, thus requiring a procedure unique and personalized on the basis of the model of SSD controller and used memory chips used.
