Alert Less than 20% of volume data's capacity is free. Performance on volume data will degrade
Firmware 6.10.3 I am seeing this allert Less than 20% of volume data's capacity is free. Performance on volume data will degrade if additional capacity is consumed. NETGEAR recommends that you ad...

Just to clarify the volume size. With XRAID/RAID-5 the volume capacity for 4x4TB is 12 TB. The other 4 TB are used for RAID parity blocks (which is what the system uses to rebuild a disk when it is replaced).
But the NAS reports sizes in TiB (1024*1024*1024*1024 bytes), not TB (1000*1000*1000*1000 TB). 12 TB is the same as 10.9 TiB.
2.26/10.9 is about 20% (slighty more, but there could be some accounted for space).
The warnings are quite conservative. Generally I expand my volume when free space drops to about 15%, and I haven't had any issues with stability.
FWIW, I do leave quotas on, so I can see the space used by every share.
So, I have Quota's turned off and not going to worry about it, thanks for the tip. In my first Iomega Nas units shipped with Seagate Baracuda 7200 drives and honestly they worked pretty good for quite some time... I switched to WD RED 5400 drives as I replaced the Seagates and increased capacity and I guess I've been sticking with the Red drives since... each of my RN204 have 4e 4TB Red drives. It has just worked and it's easy to find them. Now the SMR issue has just started to show up in the last 6months of discuddions, some say the Red are and some say they are not...but going forward I'll be sure to stay away from any that are... As drives got cheaper and going to 1 platter with high compression I can only imagine the nightmare they could be. I will take a look at the compatitbility list before I do anything... Too bad I missed the sale on 8TB 5400 drives before christmas, I should have just picked up 4 of them :-)
I will checkout the NAS systems you mentioned, I"ve kind of kept my eye the market, who knows there might be a sale before New Years.... (it's my wifes birthday, I"ll buy it and tell it is for her for her birthday since she likes so many movies)... don't think it will work, but I"ll try.
My background as I had said started back in the day of the IBM, HP DEC and other computers that stood 6' tall and today would have less power than your cell phone, technlogy for the end user has reallly stepped up and I had the oppertunity at being on the front end of it.. (see your PM from me) depending on your age you may or may not remeber it...
When I was working the companines I was involved with did alot of international business so I got to travel quite a bit, I remember the days of the Hanover Fair, staning in a booth for 10 days each year and spending time with my wife traveling and visiting the different countries ..
Anyway thanks for the help I really appreciate it..

Currently shipping "Red" drives <8TB are SMR. After being called out on the issue, WD introduced the "Red Plus" line, which is still 5400RPM but also CMR. "Red Pro" are still CMR, and are 7200RPM.
So go Red Pro if I'm going to change... Good to know... They were just on sale, darn!
