Now that the prices of hard drives have drop making storage of family photos and data at home more affordable, I bought myself a DNS-321 for Christmas.    My goal is to use one drive as storage with the second DNS drive as backup.  I think that is called a RAID1 configuration? I ordered a Western Digital 2TB Green drive (WD20EARS) and I was hoping to get a second drive of a different model so that the drive will not die at the same time. After reading this forum last night, I will return the WD20EARS due to the compatibility issues.   

I am still searching for compatible drives in the 2TB range.  Please advise me if anybody here has any luck with their drives in my proposed configuration.

Thank you in advance for your assistance.

Pretty much any non-4K sector Advanced Format drive. I've had success with WD, Seagate and Samsung (currently 2TB Samsung Spinpoint F3). I've heard possitive things about the Hitachi DeskStar too.

It's been said many times, but RAID1 isn't a proper backup. It just means if a disk dies, you should still have access to your data.

Will the Seagate Barracuda LP 2 TB 5900RPM SATA 3 GB/s 32 MB Cache 3.5-Inch Internal Hard Drive ST32000542AS work?  If I install two of these, will there be a problem?

On the backup issue, if I have data on one drive, how should I back it up on the second drive?

I can't see any reason why that drive wouldn't work. It is a standard 512 byte sector drive.

When you install the drives in to the NAS you will be prompted how you wish the drives to be formatted and configured. You can use them as two separate drives, mirrored (RAID1), JBOD and RAID0.

If you would like the data to be duplicated over both drives, choose RAID1. This process will happen automatically.

Just picked up 2 WD-EADS20 2tb caviar green drives from tigerdirect yesterday ($20 rebate). Today they are installed formatted and running in raid 1.  Copied about 100gb to them so far and have no problems.

Thank you Mike,

Just wondering what operating system ( Windows XP, etc.) are you using your computers at is connected to your DNS-321?

Mike, I take it you actually got EADS drives?  That's great, as they are getting harder to find, even when sites say EADS, they sometimes ship EARS.  That happened to me with Samsung Spinpoints... bought F3 but was sent F4... 

Don't buy from Circuit City, btw... their mistake ended up costing me $25 is shipping costs after I had to pay to return them... and they couldn't care less it seems.  They lost any future business from me...

Running a custom built AVA-Direct PC with Windows 7 64 bit,  have not yet tried mapping the NAS to my kids XP PC's but I will let you know how that goes.

Just finished mapping the 321 on a secondary XP machine, no problems.
