Pros: I have thirteen (13) of this HD's 3Gbps predecessors (HGST Deskstar HD32000 IDK/7K (0S00164) 2TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drives) running since November 2009 in a RAID6 configuration with not one HD going out on me (RocketRAID 4321 SAS RAID Controller + Areca ARC-8020-16 16-Port SAS Expansion Controller Module). I decided recently to max-out the enclosure (15-bay hot swap) from 22TBs to 26TBs by adding two more, but the 3Gbps HDs weren't available anymore. So, I purchased two (2) of these 6Gbps versions. They work GREAT! After a few days of a live RAID expansion, the drives run inclusively with the older models without any issues. I continue to get 300MB(ytes)ps+ file transfers and expect them to last as long as the continually-working older HDs in the system! I ordered three (3) more of these HDs for possibly more expansion and/or spares. Can't beat $110/HD at the time...

Cons: NONE, whatsoever!!!

Overall Review: These 6Gbps HDs do work in a 3Gbps SAS system without any problems. Again, the only reason I had to use them in this system is due to the discontinued 3Gbps models of the same HD family (HD matching is very important in RAID systems...)

Pros: I have this controller and battery backup controlling 10x 2TB HDs (HITACHI Deskstar HD32000 IDK/7K (0S00164) 2TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Retail) in a "15-bay Hotswap SAS/SATA Tower Enclosure with SAS Expander" from PC Pitstop. The SAS Expander is an Areca ARC-8020-16 (3G). Great performance (up to 250 MB/s with file transfers within the RAID system and 300+ MB/s to other storage systems depending on the data connection). Monitoring features are superb! I like being able to access the controller via its HTTP interface over a dedicated ethernet connection. Being notified via e-mail of any happenings is a great plus!

Cons: None, whatsoever!

Overall Review: Great controller for the price! Nice low-cost solution for high-capacity, high-performance system...

Pros: I purchased 10 retail boxed versions of these HDs back in November 2009; configured in a RAID6 array for 16TB of storage. I added 3 more of the bare drive versions (being reviewed) 13 months later (December 2010). I haven't had ONE drive go bad after 24/7 operation for 18 months! Performance: 300+MB/s (that's megaBYTEs) sustained file transfers from one partition to another on the same RADI6 array...

Cons: Absolutely none to mention! ;o)
