1DCWH - Dell 73GB 10000RPM SAS 16MB Cache 2.5-inch Internal Hard Disk Drive

To buy the right hard drive it is important that you know the interface type of your computer. The interface type determines the compatibility to a system. Common interface types today are IDE (also known as PATA), SATA, or SCSI. SCSI interface type may come in different pin configurations.Hard drives are system specific for Laptops. However, you need to know the interface type for desktops and servers to choose the right product. Hence we recommend that you use the Service Tag feature in the Parts For Your Dell? tool to choose the right hard drive for your desktop or server. For Laptops, you can either use System Drill Down or Service Tag feature.
