Sorry the long post, but there’s no way to summarize the folliowing into TL:DR
Ripping and Remuxing DVDs and Blu-Rays
DVDFab or AnyDVD for ripping (original definition, a 1:1 bit for bit copy of contents of the disc less copy protection) DVDs and Blu-Rays into ISO or disc structure. DVDFab is free for 30 days, after which the Blu-Ray ripping portion ends, but the DVD ripping portion remains free. AnyDVD is free for 21 days and not sure what functions, if any remains free.
Handbrake isn’t an option for ripping commercial discs because it doesn’t remove the copy protection on most U.S. releases. DVDFab and AnyDVD must be continually updated to defeat these continually changing protection schemes with the free version of DVDFab lagging months behind the paid version.
MakeMKV is free while in Beta, which it has been for the past ten years. The only advantage to paying for it, other than the warm fuzzies, is that you receive a permanent license key versus having to download a new key and version of the program every few months.
Because MakeMKV is always free, updates to defeat new copy protection schemes it takes longer (sometimes months later) to be updated.
More about ripping. As stated above, ripping is the process of making an exact copy of the contents of the disc without any compression or quality loss. You can rip to ISO, which is a container that contains an exact copy of the contents and structure of the original disc contents or to folders that retain the files in the structure on the disc.
While ISO is an exact image of the optical disc, few streaming programs (e.g. Plex) will stream and ISO. And other than standalone Blu-Ray players, few standalone or Smart TV media players will play a Blu-Ray ISO. Also, few software media players on your PC will play Blu-Ray ISOs correctly.
Which leads to MakeMKV. While MakeMKV does allow you to make an ISO from a Blu-Ray, but not DVD, it’s main function is to RIP and Remux (place into a container) a disc into invdividual MKV files. Note that MKV, MP4, AVI and many others are containers and not formats. When you RIP and Remux with MakeMKV, you’re taking the video from the disc, RIPs and exact copy of the video less copy protection and places into an MKV container as an exact copy of the original.
The catch is the MKV (and MP4) container can contain only one video, but multiple audio tracks and subtile, and no menu. So each video, main movie, trailers, extras on your disc will be a separate file.
While I believe Handbrake can remux a video from an MKV container to an MP4 container. It’s primary purpose is to reencode the already highly compressed video from the disc to another even more highly compressed video format, losing quality in the process.
Because MKV and MP4 are containers, just saying “I have an MKV or MP4” id meaningless since the video format contained inside can vary greatly. The primary reason to remux a video into an MP4 container, other than reencoding is that the MP4 container is more compatible than MKV.
On to storage and hard drives.
Make these your mantras:
All hard drives will fail. DOA, 10 seconds, 10 months, 10 years.
RAID in any configuration is NOT A BACKUP! RAID is meant to maintain the integrity data on the drives in the array. Yes, there’s a degree of “backup” in the sense that data can be restored if one or more (depending on configuration) drive fail, but delete a file or overwrite a file in a RAID and it’s just as gone as if you had a single drive.
There are no truly good or truly bad drives or manufacturers. For home use, more money buys you a longer warranty, but reliability of higher level drives like Pro and Enterprise drives is based on commercial installations where 24/7 use and reliability is necessary.
Backup, backup, backup. See Mantra #1. Follow the 3-2-1 Backup strategy. 3 copies of your data (main drive and two copies), 2 on different media (one on another hard drive, a second on optical disc, cloud or tape, but not SSDs or flash drives which are not archival), 1 offsite, either physically or cloud.
As for SMR (Shingled Magnetic Recording), they’re not just for archival use or only to make drives cheaper. More about this below. SMR (imagine a how a shingled roof is built with overlapping shingles) was developed because density capacity on the drive platters (hence the term hard drive) has reached their limit. Currently the largest consumer purchasable drive is 18TB and it’s not SMR. However, the largest commercially available drive is 20TB and they are SMR because of drive form factor limitations.
Because of the nature of SMR drives, they have to erase and write the data on the overlapping shingled sectors, they’re slower on writes, but just as fast on non-shingled drives on read. This is the reason they may be considered archival drives, write rarely, read often. But for most users the write speed difference isn’t a major factor.
The write speed difference IS a factor when they’re used in a RAID configuration. To retain the integrity of the RAID array, the data on all drives must be checked and rebuilt (i.e. read, erased and rewritten). This is where SMR drives fail because the write speed is too slow. So SMR drives shouldn’t be used in a RAID.
Finally PHEW a RAID not a NAS and a NAS is not a RAID.
NAS is Network Attached Storage. That’s it. A drive or drives accessible by multiple devices on a network, now including access over the internet if desired. .
RAID (Redundant Array of Individual/Independant/Inexpensive Disks) is at least two disks in an enclosure which can be a NAS that is either striped (combined to increase speed) or mirrored. Striping and mirroring in various RAID configurations with an extra parity drive that can be used to restore corrupted data. Note that is for corrupted data only. As stated above, once you permanently delete a file or folder in a RAID, it’s gone just like on a single drive.
