Choosing a Workstation Hard Drive

You should configure your workstation with a hard drive based on your requirements for capacity measured in gigabytes (GB), rotational speed measured in revolutions per minute (RPM), interface (SATA vs PCIe) and technology (solid-state drive or hard drive).

Drive Types:

Solid-State Drives (SATA & PCIe SSD):

SSDs provide the best overall level of storage performance. SSDs have no moving parts, so their speed is not measured in RPM. In addition to offering higher performance, SSDs are also more durable, more reliable, and operate cooler and quieter than standard hard drives.
For the utmost in storage performance choose the optional PCIe M.2 NVMe SSD storage device. The PCIe SSD is a solid state storage device that has similar storage technology to a standard SSD. The difference between a standard SSD is that the PCIe SSD allows the data to transfer at the high rate of the PCIe bus which can provide extremely fast read/write performance.

7200 RPM SATA Hard drives:

For magnetic hard drives the performance is influenced by the speed of the drive measured in RPM. A 7200 rpm HDD is standard performance for desktop applications. 7200 rpm are available in the highest capacities giving you more space to store your current and future data.

SSD Boot Drive + SATA 7200 rpm Hard Drive:

Use an SSD as a boot drive configured with a 7200 rpm hard drive that offers the best of both worlds: performance and capacity. The SSD will feature fast boot up, snappy application loads and the performance benefits of the SSD. Pairing it with a SATA 7200 rpm hard drive will provide the capacity needed for current and future data storage.

Self-Encrypting Drive (SED):

Keep your data safe by using powerful, hardware-based encryption without a negative impact on performance. With SEDs, the hardware-based encryption engine is built directly into the drive controller, delivering always-on encryption helping you maintain security without significant performance degradation. Dell's SED hard drive is OPAL compliant and FIPS 140-2 certified.
