Dell U706K 300GB SAS Drive

This Dell U706K is a 300GB 2.5-inch internal hard drive spinning at 10000 RPM with a 16MB cache. It uses a SAS 6Gb/s interface and is designed for hot-pluggable server environments. The bare drive measures 0.6 inches high, 2.8 inches wide and 4 inches deep, weighing approximately 8.01 oz. It is built for Dell PowerEdge and PowerVault systems requiring high-speed storage.

Check SAS Controller and Bay Compatibility

Verify that your server or storage array has a 2.5-inch SAS drive bay and a controller supporting 6Gb/s SAS. The drive is listed as compatible with specific Dell PowerEdge models including the 2970, M605, M610, M710, M805, M905, M910, R210, R410, R510, R610, R710, R805, R810, R815, R900, R905, R910, T310, T410, T610, T710 and PowerVault NX3100, MD3200, MD3220, MD3200I, MD3220I, MD3600I, MD3620I. Ensure your chassis accepts the 0.6-inch drive height.

Fits Hot-Plug Server Chassis

This drive slides directly into a hot-plug 2.5-inch SAS tray, allowing replacement without powering down the system. It draws power and data through the standard SAS backplane connector, so no extra cabling is required. The 10000 RPM spindle and 16MB buffer deliver fast access for transactional workloads, freeing up I/O capacity on the controller for other drives in the array.

Questions about this item

Does the Dell U706K arrive as a bare drive or with mounting hardware?

It is listed for PowerEdge 2970, M605, M610, M710, M805, M905, M910, R210, R410, R510, R610, R710, R805, R810, R815, R900, R905, R910, T310, T410, T610, T710, PowerVault NX3100, MD3200, MD3220, MD3200I, MD3220I, MD3600I and MD3620I.

How does the 6Gb/s SAS interface affect throughput in a RAID array?

The 6Gb/s SAS link provides up to 600 MB/s per lane, so sustained array speed will depend on controller, stripe width and the 16MB cache.
