Hi all.

I am mainly using this for personal data: old photos, textbooks, school projects, reference data, videos, movies (ahhem, yes) and legacy programs (ahhem, yes) and tax documents (receipts, etc).

Main daily use is my personal laptop (not much inside), just for YouTube, some photo editing and such, document editing and such. My work is now backed to cloud server so that's pretty much ok. Might be a data horder...

Not a techie...

Using a windows os

Around 50GB to 100GB of data*

Personal storage 500GB SDD, 500GB HDD, 250GB HDD

Current system: Manually copy and paste

1. Important stuff gets copied everywhere (30GB).

2. Backups (half yearly, if i remember) this is done incremental (e.g. year 1: 50GB, year two 50GB + 10GB, year three 50GB+10GB+10GB; total 80GB)

3. Its really messy and I take a long time to find my files. Just thought i lost my important backup and found it hidden physically (the sdd) in my office - would like to avoid this too.

So i would like to arrange my datas so that I can access them easier and stored easier.

Budget minimum: i dont really want to spend more than I have to. And judging by the prices of storage... probably i am looking at spending less than usd 500 for an entire system. One in use and one offsite. I intend for this to be offline usage so avoid virus or other issues.

The easier way will be to use more hard drive to continue my Backups and perhaps delete old datas. But I wouldnt know if these data are corrupted during copying - it happened once before.

So please suggest a easy backup and forget system with some form of checking for corruption.

I am slightly concerned that there are some myths about filtration that running more air flow thru will make up for the drop in efficiency in filtration. That is only partially true. You will need to run alot more air.

​

For example, if you have a Hepa 13 capturing 99.97% of particles vs merv 13 capturing 75% of the same particles.

​

Running hepa 13 at cadr of 100 m3 per hour,

​

You will have to calculate

​

1st pass 0.75 efficient

2nd pass 0.25 * 0.75 efficient

3rd pass 0.25 * 0.75 * 0.75 efficient

... so on

​

Which gives the formular 1 - (1-0.75)^n = 0.9997, where n = number of passes

​

So it requires around 5.2x as much. Hence for hepa at cadr = 100 m3 per hour, You will need around 520 m3 per hour for merv.

​

It is not simply, 0.9997/0.75 x 100 = 133 m3 per hour.
