![]() NVMe SSDs can exceed even SATA SSD speeds by up to 10 times. How much faster is an SSD? This depends on both the hard drive and the solid-state drive. Western Digital PC SN720 with NVMe interface, 1 TB capacityģ,400/2,800 MB/s, sequential read/write speeds Micron 5200 ECO with SATA interface, 7.68 TB capacityĥ40/520 MB/s, sequential read/write speeds Seagate EXOS 2X18 with SATA or SAS interface, 18 TB capacity Toshiba MG Series with SATA interface, model MG06ACA800E, 8 TB capacity ![]() SSD manufacturers phrase the speed differently. Note that sustained transfer rate, or sustained data rate, is a common term that hard drive manufacturers use for the process of reading and writing data on a disk. The following table shows manufacturer-provided data on sample solid-state drive and hard drive speeds. This piece analyzes the differences between SSDs and HDDs and which storage use cases they’re most suited to, including rapid data processing and archive storage. And even though SSD prices continue to decrease overall, hard drives are still cheaper and offer cost-saving benefits to some enterprises. A SATA-interface SSD is often double the read/write speed of a SATA HDD, and some NVMe SSDs have 10 times the read and write rates of HDDs.īut hard drives are still part of the market: although hard drive shipments are decreasing overall, according to Horizon Technology, major hard drive manufacturers are still producing drives designed for enterprise storage use cases. Solid-state drives (SSDs) have become a popular storage choice for enterprises because of their high speeds compared to hard disk drives (HDDs).
