Help me buying a new ReadyNAS: looking at the 524x
Hi, Since my Ultra 2 is having unresolved V+12 voltage warnings, I am looking at a new NAS. Here are my needs: - 4 bays to run 2x RAID 1 volumes: 2 x 8TB disks for video and 2x 4TB disks for da...
A quick feedback to close topic:
Encryption has no performance impact on the 524X, so it seems to benefit completely of the AES-NI cpu instructions
The CPU is the Pentium D1508, Netgear should be really clear and precise about it, as Intel makes things confusing
Transcoding is good for my needs, even from reasonable 30 Mbps 4K material to a 1080p output using Plex
HEVC to x264 transcoding for 1080p sources is also very smooth
Power usage at idle is around 35-38W, which is excellent for my needs
I am mainly happy because of a great increase in my backup speed compared to my old Ultra 2. Backup tasks with small files is near 10x faster and multiple file copy is smooth when it was near impossible
Some performance tests:
Another question
The CPU is the Pentium D1508 or a Xeon D-1508 ? I find nothing on intel site about such a Xeon processor and Netgear remains vague about its name: server processor, omitting the Pentium and Xeon names !

The RN520 series is based on a Intel® Pentium® Processor D1508: https://ark.intel.com/products/91558/Intel-Pentium-Processor-D1508-3M-Cache-2_20-GHz
The RN620 series is based on a Intel® Xeon® Processor D-1521: https://ark.intel.com/products/91202/Intel-Xeon-Processor-D-1521-6M-Cache-2_40-GHz
Imho, it could be clearer on both Intel's and NETGEAR's sides.
The fact is that Netgear omitted the Pentium and added a "-" sign writing D-1508 instead of D1508
So, what remains:
- hardware encryption actually uses the AES-NI instructions supported by the D1508 ? Hopefully that means encryption with quiet no performance impact as the RN716 reviews I saw
- what steps should I do to migrate ?
* put the 2 disks from Ultra 2 directly on the RN524x
* start it, and later I add the 2 new disks
* it will ask me to create a new volume on the 2 new disks that will be in raid 1 ?
I also have no idea whether the RN524x software uses those instructions or not.
Personally I don't see a lot of value in using the disk encryption feature. If someone steals the NAS, the USB key will generally be installed in the system or nearby (and either way stolen too). Then the thief can still boot the system and take the data (doing an OS reinstall to get admin access).

If the ultra-2 is already running OS-6 then you move the disks from the ultra (powered down) and then boot it.
If it is running OS 4.2, then you will need to copy the data to external storage first.

You would need to turn off XRAID before you add the disks. You'll choose the RAID mode when you create the new volume.

If you boot the RN524X with the disks from the Ultra 2, it will boot like the Ultra 2, on the old system, with the old settings and with the old data volume.
If you want to use the latest OS6.7.1, you'll have to perform a Factory Default with both drives in the chassis (wiping all data and settings from it). I'd advise you to update the F/W before performing the Factory Default.
It works both ways:
- Put all four disks in the NAS. Perform a Factory Default. Access the GUI. The NAS will have a single RAID5 volume on all four drives, which is not what you want. Disable X-RAID. Destroy the volume. Create two separate volumes as wanted.
- Put the first two disks in the NAS. Perform a Factory Default. Access the GUI. The NAS will have a RAID1 volume on the two drives, which is what you want. Disable X-RAID. Insert the other two drives. Create the second volume as wanted.
If you don't have the other two drives yet, then the second option is the most relevant one.

If the ultra is running 4.2.x, then the RN524x will boot with the ultra disks installed, but the volume will be read-only. You then need to copy the data to a USB drive and do a factory reset - restoring the data back when you are done. The procedure is described here: https://kb.netgear.com/29957/ReadyNAS-Migrating-disks-from-RAIDiator-4-2-to-ReadyNAS-OS-6-x86 IMO, it's simpler to just back up the data while it's still on the ultra-2.
If the ultra is already running OS 6, you can migrate the disks, and no factory reset is needed.
