A Closer Look at SSD Failure

• One of the major areas of concern for SSD users
  is flash endurance. SSDs write data in blocks. If
  a single binary bit has to be changed, the
  operating system rewrites the entire data block.
  This in turn adds up to the SSD wear cycle count.
  The manufacturers are using different types of
  flash memory to improve P/E figures as per what
  the consumer needs. A 34 nm SLC or eMLC has 100k
  P/E cycles, which make them ideal for enterprise
  use. The SSDs using MLC or TLC NAND usually
  target PC users. Apart from buggy firmware and
  controller failure, wear out of SSD flash causes
  SSD failure resulting in data loss.
• Given the complex storage of data on SSDs, any
  type of failure is not easy to deal with. SSDs
  feature complex data structures and specialized
  controller chips. Data recovery from SSDs
  presents various challenges before the
  organizations. One of the biggest challenges is
  accessing data at the chip level and bypassing
  high-level encryption used for data security. The
  data recovery process also requires rebuilding
  data striping on SSD (somewhere resembling RAID).
  Several data recovery companies are now equipped
  to recover all data from failed SSDs. They can
  easily overcome SSD data encryption and search
  the SSD layers to recover your data. The time
  required to perform data recovery depends on the
  extent of damage and the amount of data lost.

A Closer Look at SSD Failure

• Binabot Review SSDs have emerged as a good
  alternative to meet the high performance needs of
  enterprises. However, when it comes to
  reliability and endurance, they are not the best
  option due to the wear out mechanisms that are
  inherent to all devices based on flash
  technology. Although SSDs (based on flash) are
  non-volatile, they exhibit abnormal behavior in
  times of power failures. A recent study by the
  researchers of Ohio State University and HP Labs
  brought to light five different types of failures
  in SSDs when exposed to power faults shorn
  writes, metadata corruption, bit corruption,
  unserializable writes, and dead devices.

• Integrated circuit assemblies are the only type
  of memory employed in SSDs for storing data.
  Since SSDs have no mechanical components as
  opposed to HDDs, users can rest assured that
  these drives are free of hardware damages like
  head crashes. However, SSDs are not immune to
  failures. The built-in flash chips may suffer
  from physical damage. Other aspects of data loss
  also apply to SSDs, such as viruses, human
  errors, software conflicts, and more.
