i want to make media home server to play videos music not sure how many of 10 tb hard drives will i need as for 5000 of dvds to them and what the best format to use

windows 10
may get 4k hdr player for later on

Well, are you trying to create a backup strategy -- or a streaming host?

DVD rips (or any rips for that matter) depend on compression. Does your media fall within a certain size, on average? Is it just standard DVD's, or are you ripping 720p/1080p BluRay as well?

i want to only pay them on plex and maybe 1080 maybe 720 if i see any differences on both and can i do both back up and host too and i wanna try dvd first as for bluray i got low number

What size are some of your DVD rips?

This is a question that can't be answered well; because you didn't provide adequate information.

  • do you want to rip the videos from the dvd, or back up the images?
  • What environment, OS, and file system do you intend on using?
  • is this server going to be an htpc, pure backup nas, or a mix?
  • what equipment do you already have?
  • will you be ripping the dvds yourself? do you already have images of the discs?

with no other information, your question could be answered with anywhere from ~135 GB -23.5 TB and be technically correct

4.7 gb of gigabytes

The native resolution of NTSC DVD is 480:720 at either 30 or 24 fps iirc.

There's absolutely no reason to rip at a higher resolution.

i use window 10 as it more used and less expensive
file system not sure as formata for the videos maybe a easy one with good quality over any tv
server or host to have at home for watching videos and tv mostly i want to watch and maybe back up as if one of them fail i don't need to do it again
i want to get 7700k for 4k playback and i want to buy 10 tb hard drives as this will be new build for our familiy members
i will be ripping this from dvds from my familiy collection

Given the semi-vagueness of your answer...
(I know I could never answer how much space would I need in the future.)
I suggest a flexible approach where you start off with a few high-capacity redundant drives, and you can add to your array / storage pool later.

IDK what method is best for that? But I'm sure others do.

I'm sorry that we're not communicating effectively here. Is English your first language? I don't mean to be rude, but you may want to ask on a forum hosted in your native tongue for better quality advice.

When you rip your video, do the following:

  • install handbrake.
  • use handbrake to rip your DVD, select all of the footage available, or just the longest one if it's a movie disc.
  • use 480:720 at 25fps (if you're in a PAL region, 30 if NTSC) at constant quality, h.264 compression level 18-20
  • name the resulting file whatever you want and save in an appropriate directory

If you follow these guidelines, you shouldn't need more than a few (1-3) TB of storage.

i am mix of american mexican familiy and i am in the japanese community so my spelling it not the best as speaking and spelling are two different things for me as my job is mostly to follow order or make things with out words some times mess with allot of my writing skills and am from the midwest

Your post and title lead to two different questions. I'll answer the title.

Depending on how you want to backup for each TB of HDD space you buy you want to be 1 to 3 TB of backup storage.

1TB if you just want a single backup of all data
2TB if you want above + offsite backup (warm)
3TB if you want a single backup + offsite backup (warm) + air gapped backup

is there easy guide for this

While a DVD can hold 4.7GB, I find that the movies themselves typically are around 4GB. I use MakeMKV to rip my Blu-Rays and DVDs without any compression (to get the best possible quality). I have some 2GB movies, I have some that are 4.9GB, but most are in that 3.6 to 4.3GB region. With Handbrake you should be able to reduce that to around 2GB without really noticing the loss of quality.

5000 DVDs at 2GB per movie = 10TB

Seeing as your 10TB drive only has 9.3 TB of usable space, you're going to be cutting it real close with a single HDD, so I'd suggest getting 2 for main storage. That way you'll have room to expand and you don't have to worry if your movies turn out to be 2.5 or even 3GB.

Then there's the matter of backup. How much security do you want?
I have about 12TB of Blu-Rays on my NAS and have everything backed up to three external 5TB drives. If one of those dies at the same time as the RAID array in the NAS, I'll just re-rip the movies that were on there again.
With 150 or so Blu-rays and a couple dozen series on Blu-Ray, re-ripping a third of my stuff is manageable if I spread it out over a month or so. With 5000 DVDs however ... that's going to take a while. You're not going to want to do that a second time.

Personally I'd suggest backing up to smaller drives. 3TB to 5TB is ideal. That way a small error or a user mistake (dropping the drive, for instance) only costs you a smaller part of your backup.

what if i want to add 2 or 3 10 tb or 8 tb and the os may be on m.2 and can i add videos on per hardrive until it full and is it easy to full recovery or i need to have it raids on nasa

Raid is not a backup. You can, by all means, use a raid setup but dont expect that to be 100% fault tolerant. Its not uncommon for a disk to fail during a rebuild of a raid and depending on the level of the raid you might lose everything. If you truly care about your data you should at the very least have an actual backup. My suggestion would be 3 identically sized drives, one for storing, one for backup, one for offsite if you care that much about it. You could run raid 1 with a third drive for backup if you wanted a little fault tolerance.

When using Handbrake (after you ripped the DVD with MakeMKV, which results in a MKV file with MPEG2 codec) you can also opt to use h265 instead of h264. This should result in even smaller files at the same quality at the cost of additional processing power usage of your CPU. That being said, my RPi3 seems fine with h265 so your 7700k should be as well.

Concerning the title: 1 unit of storage needs roughly 3 units of redundancy to be safe. (You need to protect against disc failure and bit rot)
