Solid-state drives, or SSDs, are storage devices that use flash memory chips to store data, instead of the hard disk magnetic platters. Flash memory chips use less power and, because they have no moving parts, are not prone to mechanical failure, but are more expensive than magnetic platters, which means SSDs cost more than hard disks with a much greater storage capacity. Samsung’s 128G-byte and 64G-byte SSDs are available in 1.8-inch and 2.5-inch versions that can fit a range of devices. Samsung also makes SSDs with capacities of 32G bytes and 64G bytes. According to reports, the 128 Gb SSD, which is built from 64 MLC NAND flash memory chips of 16 Gb each, is energy efficient at 0.2 watts in standby mode and 0.5 watts in active mode and Samsung claims the drives will last 20 times longer than the average 4-5 years of hard drives – which would mean that the SSD is rated at 80-100 years. The company wont name customers for these SSDs but is a regular supplier for several notebook producers, including Apple for its MacBook Air, Lenovo and its ThinkPad X300, as well as multiple performance systems from Dell.
