External SSD - Time Machine

My recommendation is to have more than just one backup device.

SSDs tend to be expensive, and when they fail they do so catastrophically and without warning. Hard disks are less expensive. They tend to fail over a long period of time, becoming slow and / or noisy, and Time Machine will eventually begin to complain it couldn't complete a backup.

Also, you — usually — get what you pay for. OWC / MacSales products (for example) are more expensive for a reason.

Be sure to encrypt the backup. The reason is that when the device fails (not if but when) you can just throw it away with no concern for its contents. An unencrypted Time Machine backup can be used to create an exact duplicate of the source Mac's contents without having to provide the encryption password. After all that is its purpose, but you don't want anyone to do that but you.

Recommendations for external SSD drives for Time Machine backups. Thanks in advance.

See what is sold locally ...(?) Best Buy, Office Max...

HDD mechanical drives are less expensive.. and will work with TM

SSD solid state drives are more expensive, esp today...

Recommended twice the size of your internal drive

Any new drive should be erased and reformatted to remove any proprietary software preinstalled:

Erase and reformat a storage device in Disk Utility on Mac

Back up your Mac Back up your Mac with Time Machine - Apple Support

Use external storage devices with Mac
