For WD Caviar Green series, here is a official document from WD for your reference:http://www.wdc.com/wdproducts/library/S ... 701229.pdf
Please read the paragraph at the bottom of first page:
- Business Critical RAID Environments – WD Caviar Green Hard Drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WD’s Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like enhanced RAFF technology and thermal extended burn-in testing.
Due to this document from WD, we do NOT suggest to use WD Green Series drives to build RAID, and WD EARS, EARX or EZRX drives are not on our HDD compatibility list of N0503/N4200 series/N5500/N7700 series/N8800 series/XXX series now.
Thanks for your understanding.
