ReadyNAS Device Compatibility List

After a 48 hours non-stop data upload I think my NAS is okay. :)

ReadyNAS NV+ RND4000 1024Mb RAM v4.1.7.T49 beta "experimental" firmware with factory default settings
Cage 1: WD20EARS-00MVWB0 (4kb sector, 3 platter)
Cage 2: WD20EARS-00MVWB0 (4kb sector, 3 platter)
Cage 3: WD20EARS-00S8B1 (4kb sector, 4 platter)
Cage 4: WD20EARS-00S8B1 (4kb sector, 4 platter)
TP-Link TL-WR1043ND router 4-port Gigabit Ethernet switch with "N" WireLess and Cat5E cables (no Jumbo Frame support)
PC: Intel Q9550@3570MHz, 2x2Gb DDRII-1120MHz, 2x32Gb Samsung SSD in RAID 0 for system,
2x750GB Samsung HDD in RAID 0 for applications, Atheros AR8121 Gigabit Ethernet (has Jumbo Frame suppor)
Acer RevoView mediaplayer unit with 250GB internal HDD

IOMeter results are almost same like "official" results, 31MB/sec read, 24MB/sec write.
The mounted network drive performance via Total Commander and drag and drop copy is around 16-18MB/sec.

After so many tries and changes I have to accept, this unit has a relatively slow hardware,
that is why shows a moderate performance in Windows 7 x64, but in summary I am satisfied with this super NAS! :)

I'm pretty sure the 00S8B1 are 4k sector drives too from reading about them on this forum and elsewhere on the web. Your performance numbers look good.

Yes, you get what you pay for. The more expensive units have faster performance. The NV+ is a good reliable unit (I have two of them), but the x86 units are quicker. You can see a good comparison of performance expectations for various ReadyNAS here: http://home.bott.ca/webserver/?p=363

Indeed ( i fix that ).
Differency is the platter number, 00S8B1 has 4 platters (500gigs/platter), the 00MVWB1 has only 3 ( 666gigs/platter).

I got this answer from official TP-Link support:

Dear Andrew,
Thank you for your email.
Our TL-WR1043ND supports Jumbo Frame very well. You don’t have to make any special setting for that. The jumbo frame will be automatically transferred.
Any further help, please feel free to contact us.
Best Regards

If I enable the Jumbo Frame support on RND4000 the performance drops dramaticaly.
The 2-4MB/sec read and write performance is definitely not "jumbo". :)

Darquebus your computer's NIC needs to not just support jumbo frames but be configured to use them as well. You should also be using Cat5e ethernet cables or newer.

Now consider that the Constellation drives fail testing - why? They are 512 byte sector drives and *should* work. Is it due to "Bad" drives? Or an issue with the NAS? Has to be one of the 2. If it is an issue with the NAS, maybe Netgear cannot or will not fix it - or don't consider it worth the effort. If Netgear came out and said this would you accept it and ask no more? Probably not as otherwise these last few posts would not exist.

Sorry, I didn't realize you were omniscient.

As a matter of fact, I would accept if Netgear said those drives don't and won't work in the NV+. I could make an informed decision either to investigate other drives or a newer NAS. As it stands now, I'm stuck waiting to see if they'll ever add them to the list.

I'd love for them to tell me which of your three options it is.

If the fault is in the drives - would Netgear publicise that? And risk causing issues between them and Seagate?

Why not? You think the SN04 issue didn't cause issues between them?

My contention is [they don't work] as I suggested in my original post as these drives have been available for a considerable time, when the NV+ was still a focus sell.

Uh, no, the 2TB Constellations may have been announced while the NV+ was a focus sell, but by the time they reached the market, the NVX was the current model. In fact, looking at the 2TB drives they did test with the NV+, it seems pretty likely that they just stopped testing new drives on the NV+.

But I really would like for them to test the only enterprise-grade 2TB drive available.

I own the NV+ and one of these drives now. If they work, I'll buy more and put them in the NAS. Please oh please report back, Netgear!!

Can I use one of these http://www.amazon.com/Western-Digital-Caviar-Desktop-WD2001FASS/dp/B002MD05SA/ref=sr_1_8?m=ATVPDKIKX0DER&s=pc&ie=UTF8&qid=1287956270&sr=1-8 in my ReadyNAS Duo? Thanks.

Stupid question: Are all the hard disks in the Duo list compatible? Does it not matter which one I pick? I see that there are 2TB options there, but I thought 1TB was the maximum size for each disk?

Yes all the drives in that list are compatible with the Duo.

I would avoid the WD Green disks for now, particularly the WD 2TB one.

1TB used to be the maximum when 1TB disks were the max capacity disk available. Since 2TB disks came out, firmware updates have made it possible to use 2TB disks.
