| 1466305 | 2020-01-29 22:43:00 | I have two 4TB seagate green drives of different ages that were giving me issues when used in an old QNAP NAS. One supposedly had a SMART error and the other had an I/O failure (think that was my fault). They also were in a striped array that failed in some weird QNAP way - data was gone but apps were still there and capacity was down to 4tb not 8, the NAS won't boot without a drive installed and stores installed apps on the drives so maybe it uses some space not in the RAID array for that *shrug* not important just curious. I moved to a newer 4 bay NAS a while ago and this one was only booting up once a week to backup some of that data. I took them out of the NAS and did a bunch of tests with seatools and haven't been able to fault them but I still don't trust them not to fail on me. So I thought I'd create a software mirror in windows and use them as non critical storage with some hardware redundancy. So to the question in the title, should I use windows disk management to create a mirror or storage spaces, and why ? I kinda need to rationalise my storage but it's a long winded exercise that I can't really be bothered with. I think the QNAP is officially retired after this. I also built my own NAS a while back as an experiment and that's still sitting there if I need it, but I stole the drives out of it so I'd have to start over. |

| 1466306 | 2020-01-30 04:48:00 | I like simple. So I have 2 internal drives and 2 external. 1 of each has my image on them, and my file backups. The other external has file backups only. Works for me. I hate raid and such... |

| 1466307 | 2020-01-30 21:18:00 | NEVER use Greens in a NAS. NEVER . Thats why you had issues . Get a HD designed for use in a NAS. WD greens are garbage. I guess Seagate Greens are just as bad ? "Keep it simple" rule applies, so use Disk management to create a 2 Drive Mirror. Note , that a mirror is not a substitute for a backup. You MUST backup that mirrored partition (drives) So why even bother with a mirror in a home PC, you are just creating problems for yourself. Keep it simple, so use one of those drives in the PC, stick the other in a USB case & use for backup. That will give you less issues A single drive failing in a mirror can end up corrupting both drives in the mirror, seen it happen . Mirrors on home PC's are more trouble than they are worth . I wouldnt use Greens on a mirror regardless. You run the risk on sync issues from their power save mode. |

| 1466308 | 2020-01-30 21:49:00 | It's kinda how I feel too, the mirror thing though - it's just me trying to mitigate the reality which is that I'll use one drive, do a backup or two, then never bother to backup again rendering the backup useless. So a mirror at least gives some hardware failure protection is what I was thinking. I know better but that's just what actually happens. And as far as not using greens in a NAS, I am aware. I used to have a pair of WD red drives in the NAS, and these 2 green drives in my PC. Once a week the PC was set to back up the NAS onto the two Green drives and that's all they did. when I replaced the NAS with a larger one I figured the old NAS could take over the backup duties and set it to only boot up once a week and run a backup then shut down again. The issues around green drives in a NAS are largely around them going to sleep and taking too long to wake up again so the controller thinks a drive is missing. I didn't think this would be an issue in my use case, but apparently it is. I do have a couple enclosures around so I think I'll do as you suggest but I'm not confident that regular backups are ever going to happen. But it's not a must for me, nothing I have stored is irreplaceable or a major problem if I lose it. Annoying, inconvenient, and time consuming, but not the end of the world so I disagree with the MUST and instead call it a SHOULD. There are things I don't wan't to lose, some photos, my music collection, some other files. All of that exists in multiple places because I don't want to lose it. Everything else is less important. Although my NAS has a lot of storage it's all for convenience and none of it really matters. |
