Based on what I've seen, I back this up because I've dealt with a damaged hard drive (due to improper shutdown). There are several benefits worth mentioning: RAM operates quicker than ROM, which can boost performance for simple tasks. It may offer better security if you store data on a USB rather than the main drive, keeping information outside the computer. You can free up space by moving operating systems and updates to other drives, avoiding unnecessary usage of storage. Running OS from a USB makes replacement simpler compared to SSDs or HDDs when signs of wear appear. Accessing files or changing system behavior becomes straightforward via USB OTG with compatible devices. Linux supports this easily, though some might question its widespread adoption. Potential downsides aren’t clear here, but I’m not sure why it isn’t more common.
Volatile memory lacks safeguards against power interruptions or outages, unlike premium HDDs and SSDs. Certain operating systems, like Windows, also demand more RAM than users usually possess. Though some Linux distributions can run entirely in RAM, they tend to be compact and designed for specific tasks such as system recovery or network testing. RAM offers quicker access compared to HDD/SSD, but its cost per gigabyte is higher, and the performance gap when using RAM as storage is minimal. USB drives provide equivalent security to hot-swapping or external HDDs/SSDs. Various encryption solutions are also available.
File corruption can occur with USB drives when shutdowns are improper, which is why replacing a USB is simpler than swapping an SSD or HDD. The method I understand requires finding another PC or entering a clean OS to reinstall everything after suspecting issues. With an internal drive, just disconnect the old one, connect the new one, and reinstall your operating system and applications.
Hot-swappable HDDs/SSDs are becoming less common nowadays. The existing USB standard helps somewhat, but it's still slower than SATA, eSATA, and M.2. I'm curious about whether data remains safe if you keep the original files in ROM and avoid using RAM alone. Flash storage might also be more resistant to power surges.
Having a backup in ROM reduces the advantages of RAM disks. The extent of this loss relies on how often the backups occur. While it has some value, it's not suitable for everyday use.
Memory cells show greater responsiveness compared to solid-state drives (SSDs). Data can sometimes change unexpectedly because of cosmic rays, external interference, or power supply issues. RAM helps boost system performance by acting as a file cache, though loading operating systems entirely into RAM at startup isn't practical. Running from ROM was attempted by Microsoft in earlier days, even with Windows 95 supporting it. However, the approach faced many problems and was eventually discontinued.
