ReadyNAS 214 Tier Configuration
Dear All,
I am new to forum, so I have had new ReadyNAS 214 four bay and did not setup yet. I am planning to configure it 3x2TB WD NAS Hard Drive using FlexRAID 0, but i need to know about tier setup, (i also have a 128GB SSD) is it possible to use it for metadata tiering or data tire, is it worth for any performance gain?
(I do not know the needed size of ssd capacity for 3x2TB=6TB flex-RAID 0)
Thx.
Personally I think a better plan would be to use two larger mechanical disks in RAID-1 (at 2x6 TB), and then use a pair of SSDs.
It'd be risky to use a single SSD for metadata tiering. It's not a cache, so if the disk fails you could lose your volume. I'm not sure if you can only do data tiering, or if data tiering includes metadata tiering. But even data tiering is described as "mostly temporary". https://kb.netgear.com/000060806/ReadyNAS-OS-6-10-Data-Tiering
But if you are also using RAID-0 for the mechanical disk, I guess you are already giving up on RAID redundancy.
As far as size goes, I suggest setting up the NAS w/o the SSD first, and see if the performance is ok for you. That would also give some more info on the amount of metadata your volume uses.
Personally I am ok w/o it on my RN526x. The data tiering won't help with large file speeds (which is limited by the network). Metadata tiering would be helpful for browsing large folders.

Thanks StephenB,
so i have just 3x2TB HDD nothing more, as my understanding it is risky and not worth to setup like this tier thing,
I am thinking to setup raid 0 directly :-) old fashion way.
Btw. Which tool can calculate the disk transfer speed for my NS214, is there any sofware to compare NAS disk performance,
eg. with or w/o SSD tier so i can decide to configure it.
thx.
For large file transfer tests, I use NasTester. http://www.808.dk/?code-csharp-nas-performance But that won't give you much information on ReadyTier performance, since those transfers are limited by your network.
I don't know of a good tool for measuring directory browsing and small file transfers. Intel did make a tool called NASPT, but it was end-of-lifed quite a while ago, and I don't have any experience with it. I suppose you could create some windows scripts that copied folders, etc and simply time them.
