Then there is no real need anymore to run a RAID for reliability. Also because I started small with 1 disc Volume 1 (Samsung EcoGreen F2 1,5TB, 5400rpm, 32MB, SATA-300, type HD154UI), then expanded with a 2nd disc Volume 2 (Samsung EcoGreen F3 2TB, 5400rpm, 32MB, SATA-300, type HD203WI) and finally added a third disc Volume 3 (Western Digital Caviar Green 3TB, 5400rpm, 64MB, SATA-300, type WD30EZRSDTL).
This 3TB drive installed on both the CS407 and DS410J without any problem, with full 3TB available (of course). I didn't pick the SATA-600 WD30EZRX drive, because the NAS doesn't need the extra SATA3 speed and I didn't want to take the extra risk on incompatibility.
By the way on the backup DS410J all 3 drives are combined to one single JBOD volume, because as far as I know, you can only bakcup with Synology NetBackup to one volume.
If anybody can tell me how to add the WD30EZRSDTL to the user compatibility list on the forum, please tell me or do it for me.
