Can someone explain to me how read/write speeds work and how i can obtain fast speeds :)

Hi there,

i've been doing some pc stuff for some time now and i've been curious all this time.

How exactly does the advertised read/write speed work and how does it translate to the 400-700 mb/s speeds i experience when for example: copying a game to my second ssd.

Im also curious how i could improve my drive's speeds to whats advertized (6.300 mb/s) (showing 400-600 when copying files/games).

Last question which im also curious how i obtain 1gbps copy speeds on my ssd's.

My specs:

Also recently bought an external ssd +enclosure via usb-c: Kinston Fury renegade 1TB https://tweakers.net/pricewatch/1759900/kingston-fury-renegade-ssd-heat-spreader-1tb.html

Hope someone can provide me with some answers

For any questions u can ping me and contact me in any way.

The speeds listed are best case. If you're doing a copy from another drive, you might be limited by the speed of that other drive for example. Or if you're copying to/from the same drive, you're dividing the time between the two.

 

Also the speeds are usually for sequential transfers. So think big files. If you're moving small files, there will be a lot more overhead to manage them.

There is basically no real world situation where you'll see your drives' advertised max speeds in action, when benchmarking maybe but when actually using them there's always something else factoring in to limit things.

Don't think I've ever seen real-world speeds >1.5GB/s or so doing anything with my PCIe4 SSD on a 13900K system.
