Rule 1: All hard drives fail. ALL OF THEM!
Rule 2: 100% of hard drives fail. ALL OF THEM!
Rule 3: ALL hard drives fail. ALL OF THEM!
The only way to protect your data locally is by using something called RAID (it's a computer acronym for Redundant Array of Inexpensive Disks). While there are DAS (Direct-Attached-Storage) RAID devices, unless it's USB 3, I would go with a NAS (Network-Attached-Storage) device. The issue is SPEED. (You can also backup your data [porn collection?] in the cloud, but that's a monthly cost...)
There are low-end NAS RAID arrays out there for $200-300. I have used inexpensive models from QNAP and Synology - both have worked well for me and my clients. (My own porn collection is on a QNAP 4-drive NAS device).
But, a few caveats:
- There is a considerable up-front cost to a RAID device: the RAID box itself doesn't have any storage (drives), so you have to "populate" the box with hard drives... multiple drives!
- You have to routinely check the system to ensure that the inevitable drive failures are detected and the failing/failed devices are replaced quickly.
So some quick computerese technology stuff... There are multiple "levels" of RAID:
- RAID 0 simply spreads your data across multiple drives, but offers NO PROTECTION! (if ONE drive fails, you may lose ALL of your data!) -- NOT RECOMMENDED!
- RAID 1 (called a mirror) copies whatever is on one disk to a 2nd disk. Thus, if you lose a disk, there is a complete copy right there! (BEST PROTECTION, HIGHEST COST: buy 2 4TB drives and store up to 4TB of data!)
- RAID 5 (most common) spreads your data across all of your drives, but sets aside storage too for a "checksum". The amount of storage "lost" for the checksum is determined by the number of drives in the array: use just 3 drives, and you lose 1/3 of the raw storage to data protection.
The most common small-business (or, in my case personal) array is a 4-drive unit, with all 4 drives populated. Assume you purchase 4 5TB drives... you will store data on 3/4 of the total storage area, and 1/4 will be used for data protection. The math, then, is that your 4 5TB drives will allow you to store AND PROTECT 15TB of data (the last 5TB of data is used to provide protection).
Now, you can see why there is a large up-front cost:
- $200-300 for the RAID device
- $100 EACH for 4TB Seagate IronWolf drives TIMES 4!
That's $600-700!
BUT, if you make that investment, you won't ever have to start over again (so long as you keep an eye on it! Drives fail - and so long as you lose only ONE DRIVE, your RAID ARRAY will keep your data safe!
