2 TB Drives Supported Ultra 4 Plus - High Speed

[boblam]

I am interested in the ReadyNAS Ultra 4 Plus, but most that I find are diskless. What is a fast 2 GB drive that will work with this device?

For example, it looks like most sites have:
Seagate Barracuda Green ST2000DL003 2TB 5900 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive ($120)

But for the same price, I can get the
Seagate Barracuda ST2000DM001 2TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive ($120)
It would seem that this drive would be faster based on teh 7200 RPM than the drive above.

It looks like the one that I have seen in the performance testing is (but cost substantially more) is:
Seagate Constellation ES 2 TB 7200 RPM SATA 3 GB/s 64 MB Cache 3.5-Inch Hard Drive - ST32000644NS ($290)
but it would seem like this should be slower based on 3 GB/s

Any thoughts on a fast 2 TB drive that works with Ultra 4 Plus?

Any advice on where to purchase this device / drives?

I'm also confused as to why most vendors sell this as part # RNDP400U-100NAS and then reference iSCSI.

Not really. The 3 GB/s SATA speed is much faster than the raw drive speed. The reason for the higher price is that these are enterprise (server) class drives, not desktop drives.

I think you found them. Green drives will be somewhat slower than the 7200 rpm drives (10% is a number frequently cited here). Also check the HCL, since Netgear support is limited if get drives that are not on their list.

Someplace that will let you exchange them in a 30 day window for new drives if one fails. Amazon or Newegg both have this policy. Manufacturer replacements are refurbished, so it is best to have a retailer that has a good replacement policy.

What are you confused about? iSCSI is a product feature.

Thanks for the feedback.

My only confusion on the iSCSI part is that when I look at purchasing the device, there is typically a model number like:
RNDP400U-100NAS

Wasn't sure if the suffix (100NAS) really meant something or just an adder to the base part number for vendor identification. I wanted to make sure I didn't need different drives or the device had different features based on the suffix.

I'm thinking about the Seagate Barracuda ST2000DM001 2TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive ($120)
It looks like people have had success using it on the community hardware list (viewtopic.php?f=83&t=58882). The actual HCL looks pretty limited and almost impossible to purchase drives from (http://www.readynas.com/?page_id=82).

Anyone have an issue with this drive?

In RNDP400U-100NAS, the 100 means v1 and the NAS is the region code (North America, I think).

It is recommended that you stick to the compatibility list. If you have issues using drives outside the list NetGear will be unable to help.

Also, iSCSI is a software feature, and is totally unrelated to the hardware specifications and drive choices.

Yes, the NAS is North America and comes with the NEMA standard 3 prong grounded modular cord. Other regions that I am familiar with (thanks to the international flavor of this forum) is AUS for Australia (and I think New Zealand) and EUS for the European Community. On older units such as the NV+ (v1) now discontinued had a UK specific designation, but now from what users are reporting is that the EUS units have both the UK modular cord as well as the European continent modular cord. The NA units are 110/120 volts whereas I believe most of the rest of the international units are 220/240 volts (but I could be wrong on that).
