If your SSD has not been properly initialized or partitioned, it may not show up in Windows. You can fix this by re-partitioning the drive. You can also use Samsung Magician, a free software suite that offers a user-friendly set of optimization tools to get the most out of your SSD.
An SSD has a limited number of writes before it starts slowing down. This can be prevented by avoiding extreme temperatures and not writing too much to the drive. Also, be sure to always keep some free space on the drive. Lastly, make sure to back up your data to another location to prevent loss of files.
An SSD has a more stable operation than a hard disk drive, but it is not completely reliable. For example, a SSD has higher uncorrectable bit error rates (UBER) than HDDs. Although UBER rates do not predict failure, they can cause loss of data. To mitigate this, be careful when installing an SSD in a laptop and always use a battery-powered external hard drive to back up your data. You should also limit the frequency of writing to your SSD to avoid consuming too much of its lifetime. In addition, you should use a power supply that provides consistent voltage to the SSD. This will improve its lifespan. Also, do not use defragmenters on your SSD.
