Ubuntu on MicroSD?
Operating an OS is similar to moving files in and out of a storage device. You may not achieve optimal speed since MicroSD cards generally offer slower read/write rates compared to SSDs or hard drives, though this won't harm the device.
Yes, you can use them if you rely on them often. SD cards aren't ideal for running operating systems because they're slow and of lower quality, which can lead to failures over time.
SD cards offer a reduced write cycle, making them more affordable compared to SSDs. The quickest available SD card is UHS-3 at 300MB/s, which remains slower than standard SATA SSDs and remains costly. If speed and longevity aren't critical—such as for basic use in a Raspberry Pi—it's perfectly acceptable.
Yes, I've destroyed a few devices. They often turn into write-protected after some time, just like USB flash drives. Their lifespan depends on how you use them. If you mainly use them to start the operating system and save data elsewhere, they'll last much longer than if you constantly read from and write to the card. Based on your needs and the SD card's condition, they might last several years or fail in a few weeks. For something portable and dependable, I suggest using an external HDD/SSD enclosure.
