technology despite difficulty of data erasure and recovery -->
The main reason that they chose SSDs was their speed, according to Kroll Ontrack's research, which found that 92% of CIOs, CTOs and IT managers bought them because they were faster than HDDs. Sixteen percent believed SSDs to be more reliable than HDDs, while 18% said that they chose SSDs simply because they like to work with leading edge technology.
Of those IT leaders who said they had chosen not to use SSDs in their organisations over the past 12 months, 68% said that the medium was too expensive. Less than one in 10 (9%) said that they avoided SSDs because it is too difficult to recover data from them, and even fewer (3%) preferred not to use SSDs because they could not be safely erased and reused.
The survey further highlighted where usage of SSDs is most prevalent. When asked what proportion of their data storage is SSD technology, the majority of organisations (82%) said that up to 25% of their data storage is SSD, compared to 13% who say that between 26% and 50% of their data storage is SSD and just 5% who say between 51% and 75% of their storage is on SSD. More than three quarters (78%) say that they use SSDs predominantly on desktops and laptops, compared to just 12% on servers.
Kroll Ontrack highlights the top five technical issues that make data recovery from SSDs much more complex and difficult than from traditional HDDs.
1. Proprietary design and architecture: The design of SSD is rapidly developing in the pursuit of higher performance, lower cost and higher capacity. For each new design, the layout of the data, the way it is configured and the way the data is accessed changes. Consequently, the data layout needs to be mapped for each new design before a recovery can be attempted.
2. Design does not prevent data loss: The data stored on SSDs is susceptible to corruption. When electrical power is removed from an SSD, whether it is planned or unplanned, the SSD has milliseconds to save the data into the right location. If the SSD is reading or writing data at the time the power is removed this is a complex task to achieve.
3. Encryption: Using hardware or software encryption can make the ability to recover data quickly significantly more challenging and SSDs are more frequently encrypted than normal HDDs. Maintaining up-to-date backups of your data is even more critical with encrypted drives to ensure a quick recovery.
4. Embedded SSDs: On most tablets and smartphones, the memory, controller and associated electronics are mounted on the same circuit board as all the other electronic components. This means fault isolation and repair are far more complex than from an SSD that can be removed.
5. Number of manufacturers: There are currently over 500 manufacturers and hence the number of different designs is huge.
