Maximum time in seconds that read from disk or write to disk

The maximum time in seconds that it takes to read from or write to disk can vary depending on several factors, including the speed of the disk drive, the size of the data being read or written, and the efficiency of the file system being used.

In general, modern hard disk drives have read and write speeds that range from around 100 to 200 megabytes per second (MB/s) for consumer-grade drives, up to several gigabytes per second (GB/s) for high-end enterprise-grade drives.

The time it takes to read or write a specific amount of data will depend on the speed of the drive and the size of the data being transferred. For example, reading a small file of a few megabytes may take only a fraction of a second, while reading a large file of several hundred gigabytes could take several minutes or even hours.

It's also worth noting that solid-state drives (SSDs) can typically read and write data much faster than traditional hard drives, with speeds ranging from hundreds of MB/s up to several GB/s, depending on the drive's specifications.
