What is Solid-state drive?
[[File:MKNSSDCR60GB.jpg|thumb|A 2.5-inch [[Serial ATA]] solid-state drive]] [[File:Intel 525 mSATA SSD.jpg|thumb|Intel 525 mSATA SSD]] A '''solid-state drive''' ('''SSD''') is a [[data storage device]], typically used in a computer. It uses [[flash memory]] to store [[Information|data]] even after power is turned off. SSDs are designed to access data in the same way as traditional [[hard disk drive]]s (HDDs). An HDD can usually be directly replaced with an SSD. Most SSDs use the SATA interface, the same as what HDDs use. Some SSDs also use other interfaces for other devices, like servers and stuff. Research shows than SSDs are more reliable than HDDs. but SSDs are more likely to fail suddenly comparing to HDDs. However, the likelihood of an SSD failing is very rare. Furthermore, SSDs have been reported to exceed the manufactures specifications. The best thing about solid state drives is that they have a much faster read/write speed than hard disk drives.<ref>{{cite web|url=http://www.storagereview.com/ssd_vs_hdd|title=SSD vs HDD|publisher=StorageReview.com|accessdate=2012-06-14}}</ref> They also have no moving parts, which means they don't make noise or break as easily. However, SSDs are often more expensive than a hard drive. This also means that for the same price, someone can get much more capacity if they select an HDD instead. However, SSD prices had dropped over the years due to advancements in technology. A [[hybrid drive]] combines the features of an HDD and an SSD into one unit. It contains a large HDD and a smaller SSD [[cache]] to improve performance of frequently accessed files. A hybrid drive can offer almost the same performance as an SSD, and it can contain more capacity. The price is also lower than of an SSD. The main market for this drive are the laptop users, as these devices can accommodate no more than one drive.<ref>{{Cite web|url=https://www.lifewire.com/solid-state-hybrid-drive-833451|title=Getting the Performance of an SSD with the Capacity of a Hard Drive|last1=writer|first1=Mark Kyr
