ReadyNAS NV+ (RND4000) new disk, compatible list?
Hello,
This is from ReadyNAS NV+ manual:
Find disks that are compatible with your ReadyNAS system.
A list of compatible disks is at http://www.readynas.com/hard_disk_hcl.

Hello,
I'm have to say I am very disappointed to know that the limitation is 2TB. Because since now
I have not found any information about that. I have read hundreds times all the manuals and information
available in the internet and I haven not wound this limitation information :( why you have hidden it?
But, from the manual I see that with RAID 5 setting I can have capacity max 6 TB (4 disks with 2 TB capacity).
Could you provide information for me how I can change from RAID 1 (2 disks with 2 TB capasity) to
RAID 5 with 4 disks? What is the easy way?
Another question is can I upcrade the NV+ v1 to v2? And then to have the possibility to use 4TB disks with RAID 1 setting?
WBR, Jussi P.
Yes 4 x 2TB disks is the max supported by the NV+ (v1). When the NV+ was released 2TB disks were still long away from being released. If you're using the default X-RAID (which on Sparc ReadyNAS such as your NV+ v1 uses RAID-4 actually with a dedicated parity disk) it'll automatically handle going from 1 disk to 2 disks to 3 disks to 4 disks and expand the volume to use the capacity of the smallest disk on each disk (of course to get the volume capacity you'd get (n - 1) * capacity of smallest disk, so with 2TB disks it would be (4 - 1) * 2 = 3 * 2 = 6).
Note that disk manufacturers use TB whereas like most computers do our NAS units measure space using TiB (but call it TB). So 6TB is about 5.4TiB. It's still the same amount of space (1KB = 1000 Bytes vs 1 KiB = 1024 Bytes).
No the NV+ v2 is a very different product. It's confusing that it's named so similar to the v1. You can't move from the v1 to the v2 or vice versa. They use a different CPU architecture, different RAID format and different firmware.
- Ok, thanks for the information. I have to check this RAID from the settings, because I think it is RAID 1. I already purchased this disks: Seagate Iron Wolf ST1000VN002 4 TB Internal Hard Disk; 88.9 mm (3.5); 64 MB Cache, SATA 6Gb/s, Do you know if this is working, so I could use it as a 2 TB disk in ReadyNAS. I would like to use it because probably in future I will change to a NAS with 4 TB disks. WBR, Jussi P.
In the v1 it would be recognised as having < 1TB of capacity.
