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 versus SAS) and technology (solid-state drive or hard drive).

Serial ATA (SATA) 7,200 RPM Hard Drive:
For magnetic hard drives, the performance is influenced by the speed of the drive measured in revolutions per minute (RPM). Higher RPM means the hard drive can transfer data faster resulting in higher performance. A 7,200 rpm hard disk drive (HDD) is standard performance for desktop applications. 7,200 rpm are available in the highest capacities giving you more space to store your current and future data.

SATA 10,000 (10K) RPM Hard Drive
10K rpm hard drives boast a higher performance with fast access times and fast data read/write.

Serial Attached SCSI (SAS) 10K RPM or 15K RPM Hard Drive:
High-end hard drives require a high-end storage bus for optimal performance. SAS hard drives offer compelling elements of the SCSI and SATA worlds in a single efficient design. SAS is an excellent standard for workstation environments requiring extremely high performance and reliability. It supports the traditional SCSI command structure so it can work with SCSI software tools. In addition, SAS is a bidirectional bus, meaning data can be routed in both directions, yielding a higher number of simultaneous data transfers to and from multiple devices than SATA hard drives.

Solid-State Drives (SSDs):
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.

Note: The hard drive industry is transitioning SATA hard drives to Advanced Format technology. All Dell Precision workstations will utilize 512 emulated (512e) Advanced Format and 512b legacy technology hard drives. For more information on the technology, please visit:
