SATA 600 in Netgear ReadyNAS NV+ RND4000

Postby Jelle » Mon Jul 25, 2011 7:55 am

Hi,


Is it possible to use SATA III disks in the Netgear ReadyNAS NV+ RND4000? For example the Barracuda Green 5900.3.

I understand that the disk will only run at SATA II speed and performance, just want to know if it's possible.

Thanks for any answer.

You mean like the 2xHitachi HDS5C3030ALA630 drives I have in my NVX? Yes. They do very well in fact. All SATA drives are backward compatible, the newest drives can even be used in the SATA1 interface found in the older ReadyNAS units.

In fact a look at the specs will show that even the original SATAI drives will saturate a gigabit network. A gigabit network will transmit data at 1000Gb/s while the SATAI drives will send that data at 1,500Gb/s. The data speed of the hard drives has never been the limiting factors. In my NV+ for example with SATA1 interface, it was the CPU while in the newer desktop x-86 machines it will either be the CPU or the NIC.

So have you already purchased the NV+?

If you don't already have a NV+, I would suggest purchasing an x86 ReadyNAS (e.g. Ultra, Pro). These are much faster than the NV+. Also x86 ReadyNAS support 3TB drives which means they are much more future proof.

No, I don't have the NV+ or any other NAS at the moment. I'm still in the orientation phase and thinking about which NAS I should buy and which HDDs. My goal is to build a NAS with 4x 2TB drives in RAID 5 and when searching the internet I found the NV+. It's not the newest machine, but has a lot of features and is within my set price (250 euro max).

I'll take a look at the ultra and pro later today, thanks for the information.

I think I will go for the RND4000. It's technology might be a bit outdated, but it's within my budget limit. Maybe I'll go for an upgrade in a couple years..

It is slower than the newer models, but certainly still functional as a server. The speed is likely only to be significant when copy or reading large files (movies).

Yes, that is also my understanding for what I read on the internet. But after tweaking some performance settings it should be possible to stream BR or at least BR rip files. I don't mind that the copying proces is slow.

I simply don't know about BR files. They are so much larger than standard DVD ripped files. I know it will do fine on mp4 files, but about others I am not sure. Someone who has either tried it or successfully done it will have to reply.

I personally would have doubts because of the lower transfer speed of the NV+ (25MB/s) versus the Ultra/Pro series (60-100MB/s). It would be a close thing, as even at the full speed it would take 23 minutes to transfer a 35GB BR file. At a more leisurely 12MB/s (allowing for some glitches) it would take 49 minutes. I am using 35GB for the size of the BR file, for the only BR disk I have access to has 35GB of data on it. (It's not my disk as I don't own any, and borrowed it to test a BR drive).

That would be like trying to stream 5 DVD files, and I am not sure the NV+ can handle 5. One or two, yes. If you are definitely going to need to stream BR files, you would be wise to do some more research before committing.
