PCIe-Based Flash Storage Devices


As the name suggests, PCIe-based flash storage devices plug right into one of the PCIe slots in a system.  The PCIe bus is electrically very close to the memory and CPU in a server, which enables these flash systems to achieve extremely high throughput and I/O rates and enjoy very low levels of latency.  Given that latency is enemy number one in a storage system, this is a … [Read more...]

DIMM-based Flash Storage


SSDs in the form of SAS/SATA disks and PCI-e cards are really fast, especially when compared with the relative turtle in the storage speed race: the spinning disk.  However, some SSDs still have latency figures that can measure into three digit microseconds, which is a lifetime for some applications, such as those that support high frequency trading.  This is where Memory … [Read more...]

SAS/SATA-based Flash Storage Devices

Motherboard SATA socket

The typical hard drive form factor – either 3.5” or 2.5” in physical size – is one the most popular form factors in which to deploy flash storage as well.  This is no surprise given that flash disks are often used on server hardware as storage vendors have embraced the use of commodity hardware as their platforms of choice.  These devices, like hard drives, sport either SAS or … [Read more...]
