Which NAS for Upgrade of DUO

There should not need to be a resync every unsafe shutdown. Also, putting the NAS on a UPS (e.g. APC UPS with USB port) can help limit the number of unsafe shutdowns.

Would recommend Ultra 2. You will need to backup your data as you cannot migrate from a Sparc ReadyNAS to a x86 ReadyNAS. You can then delete the partitions on the disks (e.g. using a PC), put them in the Ultra 2 and do a factory reset (http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu)

Thanks for the reply. What real world speeds would I expect on that unit (not sure what my duo is exactly doing but it's freaking painful).

Also should I use to simply test read and write speeds to my DUO for comparison to the reviews for the Ultra2?

If using wireless, that will be the bottleneck. See ReadyNAS Performance Expectations

For an ethernet wired connection you can expect 2-3x the speed of the Duo.

See The Performance Section of The Definitive Guide to the ReadyNAS Ultra Series

Also take a look at The Performance Section of The Definitive Guide to the ReadyNAS Duo

Real world speeds will be a bit slower, but it does depend heavily on what files you are using. For large files speeds should approach what's shown in the Definitive Guides. For lots of small files speeds will be slower.

Hi Thanks for your help. Is there a table that shows all the older and current readynas units read/write performance in a grid? I have access to some ex demo ultra and nvx and plus stuff, but I am finding sorting through it all a little much, I was hoping a summary of the units performance might be already created somewhere?

I am on Gigabit ethernet.

The "Performance Expectations" link above is a good place to start.

The NVX is a 32-bit NAS (has 32-bit CPU).

Ultra, Ultra Plus and Pro are 64-bit (have 64-bit CPU).

Ultra Plus is faster than Ultra. Pro 4 is same speed as Ultra 4 Plus, Pro 2 is same speed as Ultra 2 Plus. Pro 6 is faster than Ultra 6 Plus. Ultra 6 Plus is same speed as Pro Business Edition and Pro Pioneer.

Any of the x86 units should suit you fine. Do note that the NVX (not Pioneer), Pro Series and Pro Business Edition (not the Pioneer) have business features (such as NIC teaming) and 5 year warranties on brand new purchases. Ultras/Ultra Pluses and Pioneers lack business features and have 3 year warranties.
