Can compressing C drive improve performance?

Question

I know this question has been asked a few times already, but most of the discussions I see are either from years ago when hardware was slower or are entirely theoretical/speculative. I have a fairly high-end computer (i7 with 6GB of RAM) and I've noticed that sometimes my hard drive (1TB WD Caviar Black) creates a bottleneck in performance (such as while copying a lot of large files). Can, on this computer, disk compression improve overall performance (such as by reducing read/write time)? Does anyone have first hand experience on the matter or have run benchmarks testing the performance difference?

Answer 1

no compressing will not do anything what i would do is format



what you do is right click on the C drive and click format

(you will get a warning ignore it and click ok)

hope this help!

Answer 2

Compression is actually the complete opposite of improving drive performance.

When you compress files you let the CPU convert the data for the hard drive to save space (compression) as this is done the data that is stored on the disk is compressed. Every time the data needs to be read it has to un-compress first. This will now include first caching the data to your system memory and working your CPU more by having to uncompress. Thus slowing down the process of getting data from your hard drive to your software.



I would not recommend compression at all. If you want speedier performance you can look into RAID 0'ing up another drive, Solid State Drive, or just a faster hard drive in general (the lower the seek timing and higher sustained read/write speed the better performance)



Edit: Ok I believe you are misunderstanding me. Data read from the drive will take the same amount of time whether it is compressed or not (due to data being stored on the hard drive in binary state). However compressed data takes on another step in having the CPU uncompress the data before it can be used. So, compressed data is ultimately slower.



Trust me... If compression were really that great you would see data centers compressing all of their data. They run on supercomputers hundreds of times faster than our desktop computers yet they do not compress and spend millions every year purchasing more and more drive space. Compression in the data industry is for people who don't know what their doing.

Answer 3

Do not format you're pc as Joseph Steel said u will loose everything u should no that lol





Now i have a perfect solution as this is what i do.



Go to computer >> click on ur harddrive >> left click and properties >> hard ware >> properties >> change settings >> policies now you should see Enable write catching on disk make sure that box is checked and at the bottom you will see Enable advanced performance check it and youre good to go click ok and thats it

Answer 4

Compressing your C: isn't something I would recommend to increase performance. What I would do is clean your computer up with three selective programs. One Advanced System care Two Auslogics Disk Defrag and Three Auslogics Registry cleaner.



If the bold html didn't work here are the programs;

Advanced system care

auslogics disk defrag

auslogics registry cleaner



Get all three from download.com

Answer 5

It's bad

Answer 6

it's possible yes
