RAID 5 vs. Synology Hybrid RAID (SHR) and how it works! - 341

How does SHR differ from, for instance X-RAID ?

WHat about performance? RAID5 vs SHR? And what about how many drives are active when retrieving a file? What happens if two drives fail, will I lose all files as in RAID5 or only those on that drive?

You should really hi pass your audio recordings (remove bass hum) at least 120hz and down should be removed.

I really love this video, thank you for the explanation! I bought a Synology DS1815+ and I haven't set it up yet (I have 4TBx8 drives, 32TB) But I think I will go with SHR after watching this video. I think they also have SHR2 now. I would love to see benchmarks (performance metrics) between SHR and Raid5/6 or so. Thanks again.

Great video and walk through. Thank you!

Whats the cheapst raid controler for the x3650 m3 with RAID 5 support?

Thank you guy for the detail pic.

Hi Morten, thank you for the great video. On the subject of Synology software raid with NAS certified hard drives, would you recommend 8 X 2TB HDD = 12TB SHR2 or 5 X 4TB HDD = 12TB SHR2? Both usable capacity is 12TB but I'm not sure which way is best/less risky. Only difference on synology raid calculator is, 1st setup mentioned: 4TB "used for protection" and 2nd setup mentions: 8TB "used for protection. Any help would be great!

Riktigt bra video!

Hi. Thanks again for a great video :-)
A question for raid build: I understand, that if you have made a, lets say Raid 5, and you want to change it to a Raid 6, then you have to erase all the data on the disks and rebuild the Raid. Is that correct understood?
But how does it work with SHR: I plan to begin with just 2 or 3 disks in my NAS, and therefor go with the "1 disk security", but if I later, in the future, choose to expand my NAS with more drives, and therefore want to set the SHR to "2 disk security", do the Synology then also have to erase all the data to set up this new Raid, or can I keep my data on the disks while it changes the system? (I hope my question makes sense?)

so if all the disks are the same size, what happens if two disks fail at the same time in SHR?

Thanks. Good explanation. I couldn't see the point of the separation, which I knew about. But of course, it's obvious when somebody points it out. Ingenious!

I like that explanation and can see why you like it (I would too -haha)! Gives us the opportunity to upgrade slowly as we can afford larger disks and get more space each time. Thanks!

Extremely useful video! Thanks so much for clarifying everything :)

Morten might watch EEVblog?

do you have any dell m1000e m600 i didnt see any on your rack -- im making a play server and i have the 10u rack and some parts --- do you have any videos on this server or could you do one on this series thanks --- i watch your videos - kendhill

your really good at explaining stuff. thanks for pointing me to this one!

Here is a SHR Webinar by synology if interested.

yo bra

I think it's pretty funny that you have a raid 5 video then a few days later you have a video about one crashing :p
(i think you do still have some work on your grammar, but that's expected for someone who doesn't speak it native)
