Dell offers the following types of storage products on its workstation products.

Solid-state Drives (SSDs): Dell M.2 PCIe NVMe SSDs and 2.5” SATA SSDs offer exceptional performance vs 7200 rpm HDDs1 and added durability and reliability unmatched by standard hard drives. SSDs are virtually silent and give out less heat helping create a better experience. PCIe drives with the NVMe protocol have up to 4 times the theoretical bandwidth of SATA SSDs.Dell Offers 3 Classes of SSD's a mainstream offering (Class 20 SATA or Class 40 PCIe NVMe) and a high performance offering (Class 50 PCIe NVMe).

Hard Disk Drives (HDD's): Dell Precision products offer a full range of HDDs, including FIPS-certified encrypted HDDs. Dell’s fast response free fall sensor technology can sense if a system is falling and "park" the heads in a safe position to help protect the drive from failure and potential data loss. By having this technology in the system, these Dell drives can detect and react quickly to protect your data.

PCIe based Add-in-Cards: Taking advantage of the latest M.2 SSD form factor, you can populate the Dell Ultra-Speed Drive PCIe cards with up to 2 or 4 PCIe NVMe drives of incredibly fast storage. The Ultra-Speed cards and M.2 PCIe NVMe SSDs are also available as kits than can be ordered after your system purchase, to update or expand capacity.
