hard drive speed

[_BJE_]

im wonder and i don't know the answer so im asking you guys dose a hard drive perform slower in read and write if it is filed up maybe like 80% or whatever im just curious

I think Data on the otter edge of the Drive reads and writes slower where as the inner part of the drive reads and writes faster. i remember some use to partition there drive to like a 1/3rd of the total size so they would get faster speeds by using the inner side of the disk instead. im not sure if it being full directly affects it but the fuller it is the more data i would assume is possibly around the outter edge which is slower. I can be a little off as im going off memory from years ago

Yes, due to the speed of the disk being relative to the distance from the center your writing data to, the disk writes outside to inside , thus if your hdd is almost full it will be slower to write and read new data

opposite (outside faster) due to the way rpms works but otherwise right

Well, if you think a little you arrive to the conclusion that the closer to the center part of the disk the faster you can access small info, however I think that big files are accessed at the same speed...

 

Not sure about anything I said though...

[AresKrieger]

The distance the red bug moves is larger therefor it moves faster than the blue bug

Edge to center is how data is written, so it will slow down over time, also fragmentation can occur slowing it even more

Knew i would get something wrong in there haha your right  For OP:  since 1 rotation  passes more overall surface area on the disk  at the outer edge of then one full rotation  would on the center but take the same amount of time to achieve the Full rotation more data can be read in the same amount of time equaling faster read and writes. Tried to break it down a little simpler to understand hopefully it doesnt come out as a mess of an explination

ah thanks everyone

how about bigger size drives will a 1TB 80% filled be slower then a 2TB 40%filled or will they be the same

A 2TB drive is often two disks, so about the same if it uses disk 1 fully first which I assume it will (if it didn't it would constantly switch disks) though am not sure.

hmm thanks anyway
