Re: [rrd-users] Storing RRD data and HDD I/O

Hi Ilja,

There are 2 ways to interpret your query, so I'll answer them both:

1. No, there is no difference between storing the single datum "0" or "100"
2. Depending on your OS, file system, disk drive and controller, and rrd =

layout, it is possible that storing many data will generate more disk =

I/O than storing a single datum.

HTH!
