X-RAID implemantation

Hi. I've been reading up on the difference between NAS and ordinary hard drives and one thing that pops up is TLER.

I understand that it's only really relevant if RAID is done in hardware.

So can you tell me, is X-RAID a software or hardware raid in the ReadyNAS RND4200v2

 

Thanks

Mo

Re: X-RAID implemantation

A few years ago NAS-purposed drives came out (WDC Red, Seagate Ironwolf).  Just use those instead of a consumer-grade drive.  Or of course use an enterprise-grade drive (including WDC Red Pro, Ironwolf Pro, among many others).

 

Enterprise-grade will give the fastest performance.  Reliability is supposed to be better, but good data on that is hard to find.

 

The NAS-purposed consumer grade are lower performing, although still fast enough to saturate a gigabit network connection.  They run cooler than enterprise-grade (using less power).

I have seen some folks who say that, but they appear to be pretty dated articles.  So I wouldn't assume that is still true. Also there is some additional vibration control in NAS-purposed drives (which is helpful when you have multiple drives in the same chassis).

Software raid.
