What are Solid State Drives? Solid state drives (SSD) refer to the technology in which the storage media is based on a kind of memory other than rotating disks. There is no rotating parts or motors in these drives. SSD utilize one or more kind of memory to realize the storage media such as RAM, ROM, NAND, NVRAM, and lately Flash memory. In comparison to standard hard disk drives (HDD), SSD feature: 1. Instantaneous start-up time because there is no mechanical parts 2. Very small access time, typically less than 100 microsecond 3. The latest SSD have reading/writing speeds that overcome SATA II port and saturate SATA III rate at nearly 550 MB/sec 4. Very high random read/write speeds in access of 100,000 IOPS compared to only 150 IOPS for HDD. 5. Reliability since there is no shock-prone components. 6. Windows 7 boot time as low as 7 to 20 sec. Who need the SSD: 1. Operating systems developers. 2. CAD/CAM applications with intensive graphics/designs 3. Games developers and gamer PCs 4. High speed reliable servers 5. People who like to upgrade their laptops/PCs to get top performance and do not like to wait for the cowling of the mechanical parts. Top manufacturers: 1. OCZ 2. Samsung 3. Intel 4. Sandisk 5. Kingstone 6. ADATA The only problem is their high price as compared to HDD. Typically their price is 4 to 6 times more than HDD but they worth it.
