Subject says it all. I am going to assume these two models (rndp2210 and rndp2220) ship with premium drives since their cost is significantly higher than a base rndp2000 (diskless system). I appreciate any/all comments on this.
These units will come with drives approved for continuous RAID applications, such as most "enterprise level" (or business class) drives. They may vary from WDC, Seagate, or Hitachi. The RNDP2210 will come with (2) 1TB drives, and the RNDP2220 will come with (2) 2TB drives.
All Pro series that come with drives from Netgear should have enterprise level drives according to past posts. The Ultra series and the new Duo v2 and NV+ v2 that come with drives will have consumer grade drives.
