History The rise of HDD and SSD Storage Media With IBM 350 RAMAC Birth

Hard-drive technology is relatively old-fashioned (in terms of the history of the computer). There are famous photographs of the IBM 350 RAMAC hard drive from 1956 which used fifty discs with a

width of 24 inches untul provide 3.75MB. This, of course, is the average size 128Kbps MP3 files. IBM 350 is only used by governments and industrial users, then became obsolete in 1969. Is not progress wonderful? PC with a standard drive appeared in the early 1980s, with the size of 5.25 inches and 3.5 inches for the class desktops and notebooks for class drives with 2.5-inch size coming soon thereafter. Internal cable interface has changed from SCSI to IDE to Serial and then to SATA for years, but basically doing the same thing: connecting your hard drive to the motherboard of your PC so that data can be processed. Today 2.5- and 3.5-inch drives use the SATA interface is almost exclusively (at least on most PC and Mac). Capacity has grown from a few megabytes to a few terabytes, up millions of times. Unuk size 3.5-inch HDD, the maximum capacity is 10 TB (Tera Byte), while driv 2.5 inch maximum size is 3 TB.

From The Beginning of Personal Computing

SSDs have a much more recent history. There is always the madness with these storage media from the beginning of personal computing, the bubble memory technologies such as flash (pun intended) and died in the 1970s and 80s. Current flash memory is a logical extension of the same idea. Flash memory chips store your data and do not require constant power to retain data. The first primary drive which we know as the SSD starts at the rise of netbooks in the late 2000s. In 2007, the OLPC XO-1 uses an SSD 1GB, and the Asus Eee PC 700 series uses a 2GB SSD as primary storage. SSD chips in low-end units of the Eee PC and the XO-1 is permanently soldered onto the motherboard. As netbooks, ultrabooks, and other ultraportable laptop PCs become more capable, SSD capacity increases, and finally the standard 2.5-inch form factor notebook. In this way, you can pop a 2.5-inch hard drive of a laptop or desktop and replace it easily with SSD. Other form factors emerge, such as mSATA SSD card miniPCIe, M.2 SSD, and SSD DIMM like in the Apple MacBook Air, but today many SSDs are still built into the 2.5-inch form factor. (Asiapcmag)
