Server-based Solid-State Drives (SSDs) can utilize a PCI Express (PCIe) interface to directly connect to the server CPU and function as a cache accelerator allowing frequently accessed data, or “hot” data, to be cached extremely fast. High performance PCIe SSDs with extremely efficient input/output operation and low read latency improves server efficiency and avoids having to access the data through an external storage device. PCIe SSD server acceleration is ideal for high transaction applications such as web acceleration or database queries like SQL, Oracle or SharePoint. Flash-based PCI Express SSDs not only reduce power and cost but also minimizes area because it requires less rack space for the hard disk drives (HDDs). Server-based SSDs can also be SATA or SAS drive that can be plugged into the SATA/SAS interface on the system.
