The difference: the NAND memory chip - a common source of problems.} At first glance, an SSHD disk looks the same as a regular HDD and even on closer inspection both are very similar. The difference is in the NAND memory chip, which you won't find in a regular HDD. It is a piece of firmware stored to speed up disk initialization and it is used as a cache for user data. Last but not least it is often the source of the problem or part of it.

This article was originally published in 2020 in response to the then-ongoing WD Red SMR controversy. We have added the development of the situation from 2020 to the present, the current list of affected models, a practical procedure for checking whether your drive uses SMR, and a section on what SMR means for data recovery. The technical explanation of the recording principle remains unchanged—physics hasn’t changed.* SMR-related inquiries come into our lab on a continuous basis, year after year. Clients most often ask whether the technology might apply to their particular drive, or why their RAID array unexpectedly slowed down or got stuck during a rebuild. For some use cases—especially RAID arrays and NAS units—SMR may not be the right fit, which is why it is worth understanding what SMR actually is and which drives are affected.
