Back up & Storage configuration help

JdotH · Apr 9, 2015

Hi Experts,

So first here's what I have:
Asus P8P67 EVO
Samsung 830 256Gb SSD OS Drive
2x 3TB Seagate HDD Storage
Win7 64bit

I was going to buy 2 more Seagate 3Tb drives to make a RAID10. It dawned on me though that this doesn't exactly protect me. So Im wondering if it makes more sense to RAID 0 Stripe the two 3TB drives I have for speed read/write & buy just one 3Tb+ HDD to backup to?

Also, my SSD OS Drive has no back up. So if it dies I guess I just buy a newer SSD & re-install or is there a better plan?

Thanks All

Raid 0 is not a good choice - combining drives into one big drive - but has no redundancy

But RAID 10 is. - twice the speed with redundancy.

SSD - use Windows backup onto a similar size hard drive.

Could put the two in RAID 0 for the speed and size, then have the single 3TB as a backupp as you are thinking, and can always Keep an image or two of the SSD on both the RAID and the single 3TB, then if yhe SSD fails, you can move all to the RAID, and pop the image onto the 3TB and use it as the boot/OS drive until you can replace the failed SSD (if and when it fails, if used properly SSDs can run for years, I'm still running some I got back in 2009

Raid is not a backup , raid is a redundancy.

It really depends on how paranoid you are. I have windows doing incremental backups to a raid 5 setup that also holds all my media that then backs up to another raid 5 setup.

The reason raid is not a backup solution is data flaws get replicated across the entire raid. So lets say you delete a file or need to recover from a virus or bad windows update. The raid isn't going to do shit for you. That's what the incremental backups are for.

Now what the raid will do for you is save you from hard drive failures.

So to be safe you really need both and to be super safe you need that to go to a second array. But lets be fair for a home solution that gets slightly ridiculous.

There are several ways you could go about this. You could setup multiple raids in the same machines, setup a nas to backup to, or a friend of mine just has two external hard drives he does the same backups to.

I realize there is no redundancy. This is why I am proposing using say a 4TB HDD to back up the two 3Tb (6TB total) to.
This would yield the same 2x read & write speed increases as RAID 10 but only cost me one 4TB drive at $129. Also, arguably, having 4 drives in RAID 10 means there is 4x drive failure potential. Where as a simple RAID 0 only has 2 failure points....I would just need to keep up with my back ups to the 4TB back up drive.

What do you think?

Tradesman1 :

Lol. I have had the Samsung 830 since I believe 2010.

So I think you & I are in congruence. Heres a quick recap of my plan:

-Use my two 3TB Seagates in RAID 0 (6TB total)
-Buy either one 3TB Seagate ($85) or 4TB Seagate ($129) to back up my RAID 0 to.
-Find a image software solution for my 830 SSD to put on the 6TB RAID 0

This then has less failure points than a RAID 10 with 4 drives as now I will only have 2 in RAID 0. It also affords me a separate incremental backup location. Plus this is cheaper than buy two more seagate drives to create a RAID 10 as I will only need to buy one.

I like the raid 10 idea better.

But the other way - I'd just keep the two 3TB as separate drives (e: and f

and then I'd get a 4tb and partition it into g: and h:

I'd make g: the backup for e: and h: the backup for f:

Thanks!

What do think about my gains vs if I should bother with this:

Should I get the 850 Pro 512gb as a replacement to my 830 256gb?
Heres a comparison. Not sure if its really a $270 big enough difference.

...Or I could just get the 850 Pro 256Gb for $140 just to get the speed gains.
Looked into using a M.2 or the XP941 via an adapter or Intel's new 750 NVMe SSD.......BUT it seems my mobo is limited to Sata III.

Thoughts?

Thanks for the input. See above. Thoughts?

You'd need different physical drives to back one up on the other. Maybe a small hdd would be better (and cheaper).

M.2 doesn't go with P67. M.2 is too new.

I must say - you're much more concerned with backup than the average punter. Had a bad experience?

i7Baby :

Lol. No bad experience. Just always used RAID 1 Mirror on my pc as I use it for work too. I ran out of room on that mirror (2x Velociraptor 500GB) so I bought 2 3Tb Seagates....now im just second guessing my plan & looking for advice.

*As far as the M.2 & NVMe info...I just typically research everything/my limitations before purchasing anything.

So what should I do for my storage back up again?
Also, what do you think about my 830 vs 850 Pro upgrade?

i7Baby · Apr 9, 2015

"So what should I do for my storage back up again?" - go raid10

"Also, what do you think about my 830 vs 850 Pro upgrade?" You'd need different physical drives to back one up on the other. Maybe a small hdd would be better (and cheaper).

Raid 10 it is then.

For the SSD I meant this: I have a Samsung 830 256gb now. do you believe I will see a difference if I replace it with a Samsung 850 Pro 512gb ($270) or 256gb ($140). I just feel as though my current SSD is 5 years old and not terribly fast/might die. I havent run out of room on it either (about 100gb available still).

"I have a Samsung 830 256gb now. do you believe I will see a difference if I replace it with a Samsung 850 Pro 512gb ($270) or 256gb ($140)." - No. I don't think you'd notice the difference.

I just upgraded from a 2 year old 120gb sandisk to a 250gb 850 evo because I was sick of juggling space requirements. I can't feel any difference in boot times.
