Analysis in 2013 reveals that SSD controller technology and high-speed transmission interface IC accounts for 29% and 67% of JMicron's sales, respectively. [2] In June 2014, JMicron announced the JMF670 and JMF670H. Both are 4-channel SATA SSD controllers capable of supporting up to 512 GB of storage capacity. Production was to begin in July 2014.
RAID (/ r eɪ d /; redundant array of inexpensive disks or redundant array of independent disks) [1] [2] is a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
An Intel X25-M SSD Intel P3608 NVMe flash SSD, PCI-E add-in card An Intel mSATA SSD On September 8, 2008, Intel began shipping its first mainstream solid-state drives (SSDs), the X18-M and X25-M with 80 GB and 160 GB storage capacities. [ 1 ]
RAID 01, also called RAID 0+1, is a RAID level using a mirror of stripes, achieving both replication and sharing of data between disks. [3] The usable capacity of a RAID 01 array is the same as in a RAID 1 array made of the same drives, in which one half of the drives is used to mirror the other half.
Diagram of a RAID 1 setup. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.
As SSD technology continues to improve, they are increasingly used in ultra-mobile PCs and lightweight laptop systems. The first flash-memory SSD based PC to become available was the Sony Vaio UX90, announced for pre-order on 27 June 2006 and began shipping in Japan on 3 July 2006 with a 16 GB flash memory hard drive.

In 2007, Western Digital announced the WD GP drive touting rotational speed "between 7200 and 5400 rpm", which is technically correct while also being misleading; the drive spins at 5405 rpm, and the Green Power spin speed is not variable. [22] WD GP drives are programmed to unload the heads whenever idle for a very short period of time. [23]
