What is the interface speed of the Dell 400-AUUX hard drive?

The 400-AUUX uses a SATA 6Gb/s interface, providing data transfer rates up to 6 gigabits per second. This standard enterprise interface is compatible with all Dell PowerEdge servers and PowerVault storage arrays that support SATA drives, ensuring broad deployment flexibility across datacenter environments.

What servers is the Dell 400-AUUX compatible with?

The 400-AUUX is compatible with Dell PowerEdge 14th, 15th, and 16th generation rack servers with 3.5-inch chassis, including R240, R340, R440, R540, R640, R740, R750, and R760 series. It also supports PowerEdge T-series tower servers and PowerVault storage arrays such as NX440, NX3240, MD2460, and ME5012 models.

What is the cache size and how does it affect performance?

The 400-AUUX includes 256MB of onboard cache memory. This cache reduces latency for frequently accessed data and improves throughput during sequential operations, enhancing overall I/O performance for mixed workloads typical in enterprise server environments.

What does the 2M-hour MTBF rating indicate?

The 2M-hour MTBF rating represents the mean time between failures, indicating expected reliability for continuous operation. This metric supports capacity planning and helps establish realistic replacement schedules and SLA commitments for datacenter storage infrastructure.

Does the 400-AUUX come with a mounting tray?

Yes, the 400-AUUX ships with a Dell G13 tray, enabling direct installation into compatible PowerEdge servers and PowerVault storage arrays without requiring additional adapters or mounting hardware.
