SSD Form Factor

Solid state drives are made of a controller and a number of modules of NAND flash memory chips mounted on a printed circuit board (PCB) which contains an interface with the computer. The 2.5” SSD is the most popular solid state drive as it can fit into most notebooks and desktop PCs. Some 1.8” and 3.5” SSDs are also available. The mSATA SSD is about 1/3 the size of a business card and can be found inside the new Ultrabook class of notebooks. A PCIe (PCI Express) SSD connects directly to a computer’s motherboard and can reach higher data transfer speeds than other SSDs which use various classes of SATA interface.

Solid state drives are smaller, faster, more energy-efficient, and practically indestructible with long lasting data preservation capability. There are no moving parts on an SSD, meaning that it will operate silently and is less likely to experience unexpected drive failure. SSDs use NAND flash memory for data storage. In comparison to the delicate rotating discs and magnetic heads found on HDDs, your data will always be accessible even after your SSD has reached its end of life when new data can no longer be written onto it.

Hard disk drives usually offer more storage at a lower total cost. However, when it comes to speed, quietness, power consumption, coolness and durability, solid state drives win hands down. SSDs are commonly used for additional storage to HDDs. Using an SSD as a boot drive and to store your favorite programs can significantly save you time and money in addition to fun and joy added to your computing activities.

SSD vs. USB Flash Drive

SSDs and USB flash drives both use NAND flash memory for storing data. SSDs typically use higher quality flash memory and better controllers with higher number of data channels. SSDs are designed to replace or augment hard disk drives while USB flash drives are designed to be inserted and removed repeatedly. USB flash drives are not designed to tolerate heavy reading and writing which is typical for SSDs and HDDs.
