Hard disk for Music Server

Raid 0 offers no backup, it only spans more than one drive into volume (s) Very bad if there is a drive failure. Raid 5 is good but difficult to repair if there is a failure. 1+0 is much better, gives you failure, hot swaps without downtime or data loss, but during the failure time you will suffer data SLOW downs big time, on a network sharing the files..

More smaller, faster, drives with STRIPPING, will blow your mind with speed. SSD RAID 1+0, 4-10, 2 gig SSD drives, Hot rod buddy...
FTH comes to mind, Faster than hell.

I ran SCSI II raid on my old Novel networks, for some manufacturing software...The 60 meg BOOT drive weighing close to 60 lbs each. Priam, drives with 10" platters? I think......OLD SCHOOL...LOL They were Raid 5 X 5s The rack was close to 400 lbs, the system 36, IBM ran on 220-240.  What a watt sucking setup....Sure was cool, though...HOT, was more like it, come to think of it.. Made barrels of all things...Paper, metal, HS, polys, overpacks....

Just curious about your need for 10 TB of storage - that's a lot!

Do you currently have a large collection already on hard drive that you are simply going to transfer? Or, do you have a CD collection that you are going to rip? If that latter, it it is going to take you a long time to rip 10 TB of CDs.

And, instead of ripping everything, you might think about combining a streaming service service and then ripping only those CDs that are not available from streaming. File the rest of your CDs away and just add them as needed and/or you find the time.

Of course, if you have something else going on that needs the 10 TB of storage (videos, photos, business, etc.) then ignore the above.

As someone who has a goodly amount of experience building my own very fast computers (which among other things I use for editing of 4K video material, which is a very challenging task for a computer), here are my thoughts:

I agree with @rbstehno that you don’t need speed. Also, given especially the need for a backup drive or drives I would choose a small number of large drives, rather than a multitude of smaller ones. And I don’t see any need for complicating things with RAID. Keep it simple!

What I would do is use a single 5400 rpm 10 TB drive for music storage, another 5400 rpm 10 TB (or larger) drive for backups, a self-powered external usb-connected 10 TB drive for a second backup, and something like a 7200 rpm 1 TB WD Gold drive as the system drive (i.e., the drive containing Windows and programs). (That’s more capacity than you’ll need for that drive, but I don’t think the Gold drives are available in smaller capacities). Or if you envision using the computer for unrelated purposes where a faster system drive may be desirable, consider a smaller SSD, perhaps even a Samsung M.2 2280 NVMe drive if your motherboard can support it, those being **extremely** fast.

To back up the music files I would periodically simply copy the files from the music storage drive to the other backup drives, telling Windows to skip files that are already there.

I would also consider using a disk imaging program to periodically create images of the system drive, storing the images on one or both of the backup drives. In the unlikely event of failure of the system drive that would avoid the necessity of having to reinstall and setup Windows and your programs. I suggest that you consider Terabyte Unlimited’s "Image for Windows" program, which I have used for many years with great results, or Acronis True Image, which seems to be fairly popular.

Finally, FWIW, my perception is that HGST drives (HGST now being a brand of WD) are not very popular these days, as evidenced in part by the limited number of reviews their recent drives seem to receive at NewEgg.com.

Good luck. Regards,

I think more info is needed. Is music the only thing you're putting on the drives?, how many people will access at any one time? Have you considered backup? Is this going to be a headless server running linux? 

I spent over 42 years in IT with over 30 years in the performance end of things including storage systems costing over million dollars (EMC storage), the last 10 years actually working for a solid state/hard disk manufacturer. You always need a backup no matter what raid array you use or even if you spent over a million $$ on a disk subsystem.
If I was going to build an array for music and even for video, I would go with a raid 5 or 6 which gives you better reads at the expense of slow writes. But I also don’t like using software raid, if I was going to build a raid system I would buy a 4 or more disk system that provides the difference raid configurations.
All of my systems at home, either Linux or OSX, use an ssd for the system disk but use your typical 5400 rpm drives for the other uses.
