Enterprise 300 GB SAS drive

This 2.5 inch enterprise hard drive delivers 300 GB of storage on a 6 Gb/s SAS interface. It spins at 15000 RPM with a 32 MB cache for low-latency access in transactional workloads. The drive ships new in a Dell R Series caddy for direct installation in compatible bays. It targets administrators who need high spindle speed in a small form factor.

Build and mounting

The 2.5 inch form factor fits dense server chassis and storage arrays that accept SAS drives. An included R Series caddy secures the drive and aligns the connector without extra hardware. The SAS interface supports dual-port operation for path redundancy in enterprise enclosures. Mechanical construction is rated for continuous operation in vibration-prone racks.

Included caddy impact

The bundled R Series caddy eliminates the need to source a separate tray for Dell PowerEdge or EqualLogic systems. It reduces installation time and prevents connector misalignment during hot-swap events. No additional software or firmware utilities are supplied with the drive. Buyers who need a 3.5 inch adapter or non-Dell mounting hardware must obtain those separately.

Questions about this item

Does the 6Gb/s SAS interface cap real-world transfer speeds?

The 6Gb/s SAS link sets the maximum bus bandwidth, so sustained reads and writes cannot exceed that limit even at 15000RPM.

Will the included R Series caddy fit a standard 2.5-inch drive bay?

The R Series caddy converts the 2.5-inch drive to a 3.5-inch form factor for Dell PowerEdge bays; it will not screw directly into a bare 2.5-inch bay.

What is the correct way to seat the drive in the caddy before inserting it into the server?

Align the drive connectors with the caddy's rear opening, secure the four side screws, then slide the full assembly into the bay until the latch clicks.
