Product Description
The 3ware RDC-400 and RDC-400-SATA Drive Cage expansion bays are designed specifically for applications requiring a high-performance Serial or Parallel ATA drive interface. They accommodate four 3.5-inch drive trays, all within the space of three 5.25-inch height drive bays. Their built-in backplane provides improved reliability and accommodates power and drive signal distribution. The 3ware Drive Cage expansion bays are ideal for installation in servers, industrial PCs, and rack-mountable systems as well as anywhere drive capacity exceeds drive bay availability. The 3ware RDC-400 and RDC-400-SATA Drive Cages are both equipped with fans that provide the drives an appropriately cooled environment. LED indicators on the unit¿s front panel provide real-time drive status, as each drive tray can be individually locked for improved security.

backplane failed <2 years,
By PhD Student "audiofriend" (Houston, TX USA) - See all my reviews
This review is from: 3ware Serial ATA RAID 4 Bay Drive Cage ( RDC-400 SATA ) (Personal Computers)
We used the 3Ware RDC-400-SATA enclosure for the RAID array serving our lab 32-node Linux cluster. This is a heavily-loaded scientific computing system with jobs that often run for weeks at a time, so any downtime is potentially disastrous.This 3Ware product has actually increased our downtime--the backplane failed before any of the drives. Two weeks prior to failure, the buzzer sounded. The alarm does not distinguish between fan underspeed and drive failure, but the disk array appeared fully functional, so we assumed a fan problem. Unfortunately, replacing a fan requires shutting down the system, taking the cage apart, and soldering the new fan power cables. Also, there are 3 fans on the enclosure, so fixing a fan underspeed problem may require replacing all 3 at once. And in hindsight, it's still unclear whether the buzzer was actually indicating a partial failure of the backplane. We eventually lost connection to one of the drives in the cage. After swapping cables and drives, it was clear that a backplane pass-through had failed. Since then, we've removed the cage and connected all drives directly to the 3Ware RAID card, and our disk array is back to normal. The 3Ware RMA team was unhelpful in replacing/repairing the failed unit. Pros: * The drive enclosure looks pretty, and it feels mechanically robust. Cons: * Poor quality: backplane failed <2 years * Poor design: replacement fans must be soldered in; indiscriminate alarm (is it the fan? is it drive?) Final thoughts: What good is a hot-swap drive cage if it fails before your hard drives do? If you want a drive cage that looks nice, buy 3Ware. If you want a drive cage you can depend on, go with another manufacturer and save yourself the trouble.

Must have for large RAID,
By
This review is from: 3ware Serial ATA RAID 4 Bay Drive Cage ( RDC-400 SATA ) (Personal Computers)
These cages are the best thing available for a large RAID. The problem that most people do not think of when building a RAID is the heat created by the hard drives. These boxes do an excellent job of transferring heat away from the drives. Less heat = Longer drive life.I have built two RAIDs for myself and three for customers. I have used the 3ware cage in four of them. The one that isn't using the cages has tremendous heat problems. I am using a lot more fans in that one and the noise level is considerably higher. The four RAIDs running with 3ware cages are not having any problems at all. I am currently supporting 9 cages. The only hardware problem I have had was one failed fan. The alarm went off, I found which fan went south, replaced it, and life went on. I have used 3ware tech support twice and they were very fast with a solution (both were related to software). If you are going to build a RAID, this is money well spent.
