What Is Sequential And Random Reads And Writes?

[Roasted Bunny]

Is it sorta like it reads/writes data in a order or just randomly?

[John Doe]

An order of big files, sequential means in order.

Simplest examples:
Sequential = copy and pasting things
Random = games

Would booting Windows be sequential read?

It's both a sequential and a random read. It loads up both bigger files and a lot of small files.

Random generally tends to mean a lot of small files, while sequential does so with big files (for the most part).

Thanks, it makes sense now. Thank you! :D

Its not something you really have to worry about if you using mostly an SSD; like having OS on SSD. Now to help with HDDs and sequential read, this is why you should defrag HDDs every so often, as it will put most files back in an order that makes more sense for sequential reads. That can depend on the defrag app you use though and how it is setup to defrag and re-sort the files on disk.
