initialize new 4x4TB X-RAID very slow takes 157 hours?
Hi, I purchased a new ReadyNas 214 and updated to the latest firmware 6.10.0. Added 4x 4TB disks from a set of Seagate external drives and created a fresh X-RAID volume, which is actually RAID 5.

The WD80EMAZ are rebranded WD Red drives. Though of course they have no warranty, they should perform identically to normal Reds.
The ST4000DM000 was the original version (which goes back to about 2013). Did you shuck old USB drives?
I guess there are two basic options
- wait for the resync to complete, and then take a good look at the logs - particularly disk health. I'd suggest using ssh (smartctl -x for example)
- Interrupt the resync, and test the disks - ideally with Seatools in a Windows PC.
Although the web ui isn't responsive, you might try getting the logs with RAIDar - https://kb.netgear.com/20684/ReadyNAS-Downloads
StephenB, Thanks for the reply.
When the raid is initializing, the web GUI is almost non-responsive. It takes a long time to just login on the web, and often moving between the screens just times out. Even the volume screen is not updating now, so I can't see progress on the web page, thus I don't know how much time is left now. I tried to create a share, but tried 3 times, looks like it didn't work (due to screen timeout?). The NAS is essentially useless during this period. Is this normal expectation?
In contrast, I have a QNAP 328 with 3x 8TB drives (disks from shucking) also. Building the RAID 5 took a few seconds to start, then the initializing job ran at a low priority, so maybe it took a week to finish as well, but I was able to copy files, access it like normal, and the GUI behaved normally, so I didn't even notice it was initializing... Is there a way to adjust the initialization job on ReadyNas too?

It will get sluggish during the RAID build, but I don't think the RN214 should become completely non-responsive.
Again, I suspect you are using SMR drives. Seagate switched over to SMR in the ST4000DM004 in 2017 ( https://forums.anandtech.com/threads/seagate-barracuda-3-5-4tb-st400dm004-now-using-smr-platters-with-2tb-per-platter-capacity.2523565/ ). If you are using them, you will see poor performance. Lowering the priority of the task won't fix it - the bottleneck is the drives themselves. Once the drive cache becomes full, the performance drops to a crawl. Though this performance graph is for a different SMR model, it will give you some idea of what's going on: https://www.storagereview.com/seagate_archive_hdd_review_8tb
So, what drive models are you using (and maybe also share what you are using on the QNAP)?
It's been 24hrs, the LCD shows 30% done, but the web GUI is still non-responsive. After initial login taking a minute or more, most of the "tabs" keep showing the busy animation, and just times out without showing any data after a long time.
In QNAP, I have 3x 8TB WD80EMAZ-00M9AA0.
In ReadyNas, I have 4x 4TB ST4000DM000.
QNAP has a setting for initialization priority, low, medium and high (I assume it is just linux "nice" settings). Even at high, the web GUI and windows remote folder access was quite ok...

As conclusion, the drives actually just took 3 days to build. The estimate in the web gui was about 2x as long. Afterwards, the read and write speed was about 80 megabytes per sec to and from a PC with SSD. So once you get over the first 3 days, the NAS is alright.
