They’re much more reliable than mechanical drives and much, much faster. Why do people ask the MBR vs GPT question specifically with regards to SSDs? Solid state drives are becoming the standard computer drive technology. Have a look at HDD Raid Vs SSD Raid: The Major Differences You Should Know for more information. This can offer amazing performance and redundancy advantages. Interestingly, the opposite approach of partitioning a drive is combining multiple physical drives into one virtual drive. On a modern SSD however, this problem is largely solved. Since the partitions exist on the same physical drive, there can be access contention. The downside of using partitions compared to using multiple physical drives, is that there’s a performance penalty. There are more uses for partitions besides this, but those are the most important ones. For example, most laptops have a protected partition on the main system drive that contains software and data which can restore the machine back to its factory default.


Partitions are also used for recovery purposes.
