The Dell KRH17 is a 4TB Serial ATA (SATA) 3.5" LFF Hard Drive. Increase the storage capacity of your system with the 4TB Hard Drive from Dell. Offering a rotational speed of 7.2K RPM, this drive provides fast disk access. Featuring a SATA interface, the Dell KRH17 hard drive delivers data transfer speeds of up to 6Gbps. Making it a great option for many Dell PowerEdge Systems.
 
 SATA has traditionally been used for internal storage interconnect in desktop computers to connect the host systems to hard drives and optical drives. Today, the SATA interconnect technology has evolved for much higher interconnect speeds, scalability, and reliability, surpassing the technology's originally intended applications. SATA technologies are now extensively used in enterprise-class storage and server environments in near-line storage applications where scale and costs are the primary selection driving criteria.
 
 Capacity Optimized drives such as the Dell KRH17 may provide much higher capacities, but reliability and performance are not as high. For capacity-driven workloads, such as email archives, disk-based backup, and object storage applications, high IOPS or throughput performance may be less of a priority as compared to capacity. In this case, choose cost-efficient HDDs, which can offer the greatest capacity at the lowest cost. SATA drives are the slowest but also the most cost-efficient of the three interface options. The primary benefit of SATA drives is that they can provide large capacities of storage at lower cost when compared to SAS or even NL-SAS drives. Using an all-SATA drive configuration, Dell EMC PowerEdge servers can hold vast amounts of internal, low-cost storage.
