Sandforce SF-1500 Series (Enterprise Processor) OCZ Agility 2 (with 10k random-write cap) Some Basic idea about SSD and SSD controller These devices may offer near-SSD performance for many applications.Īll SSD RAID 0 Charts 2011. Hybrid drives combine the features of SSDs and HDDs in the same unit, containing a large hard disk drive and an SSD cache to improve performance of frequently accessed data. Such devices may employ separate power sources, such as batteries, to maintain data after power loss. For applications requiring fast access, but not necessarily data persistence after power loss, SSDs may be constructed from random-access memory (RAM). SSDs share the I/O interface technology developed for hard disk drives, thus permitting simple replacement for most applications.Īs of 2010, most SSDs use NAND-based flash memory, which retains data without power. The prices have continued to decline in 2012. Compared with electromechanical disks, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency, but are, at 2011 market prices, more expensive per unit of storage.
SSDs do not employ any moving mechanical components, which distinguishes them from traditional magnetic disks such as hard disk drives (HDDs) or floppy disks, which are electromechanical devices containing spinning disks and movable read/write heads.
SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. A solid-state drive (SSD) (sometimes improperly referred to as a "solid-state disk" or "electronic disk") is a data storage device that uses integrated circuit assemblies as memory to store data persistently.
