Full Post: Exchange Server Data Recovery Most folks today cannot imagine doing without a hard disk drive. However, they were not always that common and have come a really long way within the last half a century. Nowadays there are tremendous amounts of data being stored, typically on devices known as RAID or server arrays. It's time to have a look in the history of the hard disk from it is early beginning to the current day RAID and server arrays within server farms.The very first hard drive was commercially made in 1956. It was the result of a project started in 1953 to develop a random-access file that may get data at any point in the unit, unlike tape drives which need to be read serially. The first drive was referred to as the IBM Disk File and it was a lot larger in relation to the units now you find in computers. It weighed a complete ton and only saved 3.75 megabytes of data. It consisted of 50 separate platters of data that a single head would search through to recover the desired place. This is developed for a variety of computers within it marketed, which necessitated the first standard interface to of a hard drive to your pc. This led to the next big development in hard drives in 1968 when Memorex produced the first third-party hard drive that may be used with this connector. This started a multiple decade period that will find the rise and fall of various different hard drive makers.Five years later in 1961, the first computer to use different arms for each disk platter was introduced. This made reading and writing a file considerably quicker. All heads went in tandem together along the disk with the controller choosing which one could be utilized to read the data. This device was also produced by IBM and was referred to as the IBM 1301 Disk Storage Unit. This stored 28 million characters in 20 disks and also was the first to ever use selfflying heads moving on a cushion of air on the platter. This allowed the heads to be manufactured nearer to the platter to increase storage density.In 1970, IBM created the very first computer with error correction technology. The IBM Direct-access Storage facility had an algorithm to mechanically find and correct any problems in the transmission of data. Such algorithms have become standard on all hard-drives sold today.It was the first business unit to employ a lubricated platter and low-mass heads while additionally incorporating the innovation of the sealed assembly. These systems became a typical after that, and disk drives are still called "Winchesters" in some countries including Russia. Therefore it was named after the Winchester 30-30 rifle. However, it ended up having two 70 Megabyte modules and one 30 Megabyte module.In 1974 hard disks actually started to become old as the very first model to ship 100,000 units, the IBM 62GV, was launched. It initially shipped with a capacity of 5 megabytes, later upgraded to 14 and 10 megabytes. In 1979 IBM would innovate further with the IBM 3370 using thin-film heads to further reduce the gap between the heads and also the plates. This allowed another leap in storage density.In 1980 the first commercial hard drive to surpass a gigabyte of storage was launched. The IBM 3380 had a total capacity of 2.5 gigabytes. However, it wasn't little. It weighed a total of 500 lbs. This originally was conceived of in 1979 by Shughart Technologies as a way to address space by blocks rather than the physical locations on the drive to further improving compatibility of products with different computers and operating systems. This standard would later be adopted in 1986 and incorporated into several drives prior to this.In 2000 the serial-ata standard was introduced. This might be adopted

Full Transcript: RAID 5 Recovery Most people nowadays can't imagine doing without a hard drive. However, these were not necessarily that common and have come a really long way over the past half a century. Nowadays there are huge amounts of data being stored, commonly on devices known as RAID or server arrays. It's time to take a look in the history of the hard disk from it's early start to the modern day RAID and server arrays found in server farms. The very first hard drive was commercially produced in 1956. It was the consequence of a project started in 1953 to produce a random access file that may get data at any point in the unit, unlike tape drives that must be read serially. The very first drive was referred to as the IBM Disk File and it was a good deal bigger than the units you find in computers today. It weighed a complete ton and only stored 3.75 megabytes of data. It consisted of 50 separate platters of data that a single head would search through to retrieve the specified location. Five years later in 1961, the very first computer to utilize independent arms for every disk platter was launched. This made reading and writing a file considerably quicker. All heads moved in tandem together along the disc together with the controller selecting which one would be utilized to read the data. This device was also developed by IBM and was called the IBM 1301 Disk Storage Unit. This saved 28 million figures in 20 disks and also was the first to use selfflying heads moving on a pillow of air on the platter. This allowed the heads to be produced closer to the platter to increase storage density. This is developed for a variety of computers inside it offered, which necessitated the first common interface to of the hard drive to your computer. This led to another big advancement in hard drives in 1968 when Memorex made the first third party hard drive which can be utilized with this particular connector. This began a multiple decade period that would find the rise and fall of various different hard drive manufacturers. In 1962 the first disk drive with removable media was developed. The IBM 1316 disk pack had a total capacity of 2 million figures. In 1970, IBM created the very first computer with error correction technology. The IBM Directaccess Storage facility had an algorithm to mechanically discover and correct any errors in the transmission of data. Such algorithms are becoming common on all hard drives sold today. It was the first commercial unit to employ a lubricated platter and low mass heads while additionally incorporating the innovation of a sealed assembly. These systems became a regular after that, and disk drives are even called "Winchesters" in some countries for example Russia. The developer originally planned on having two 30 Megabyte modules.

Therefore it was named after the Winchester 30-30 rifle. However, it ended up having one 30 Megabyte module and two 70 Megabyte modules. In 1974 hard drives actually begun to become old since the very first model to send 100,000 units, the IBM 62GV, premiered. It initially shipped with a capacity of 5 megabytes, later upgraded to 10 and 14 megabytes. In 1979 IBM would innovate further with the IBM 3370 using thin film heads to further reduce the gap between the heads as well as the plates. This allowed another jump in storage density. In 1980 the first commercial hard disk drive to transcend a gigabyte of storage was launched. The IBM 3380 had a total capacity of 2.5 gigabytes. However, it was not modest. It weighed a total of 500 lbs. In 1980 Shughart Engineering was the first company to placed the hard disk control within exactly the same assembly as the hard drive itself. This was an incredibly important development as it allowed different hard-drives to be more easily swapped between computers. The ST-506 was thus a significant progress in technology that might be a stepping stone for the business, after to become Seagate technologies, to become a global leader in hard drive manufacturing. 1981 saw the hdd start to lose fat. Fujitsu made the M2351A which came in a 10.1 inch formfactor. This little hard drive had a total capacity of 474.2 megabytes. In 1983 Rodime launched the first 3.5 inch drive utilizing precisely the same form-factor as many floppy drives at the time. In 1988 the first 2.5 inch hard drive assembly was created by PrairieTek. This dimension has become the industry-standard in modern times. In 1981 the Small Computer Systems Interface (SCSI) standard was proposed. This originally was conceived of in 1979 by Shughart Technology as a way to handle space by blocks rather than the actual places on the drive to further improving compatibility of devices with different computers and operating systems. This standard would later be adopted in 1986 and incorporated into many drives just before this. In 2000 the serial-ata standard was introduced. This would be adopted in 2003 and allow for higher performance and thinner cables. The standard was revised in 2005 to permit greater throughput rates of up to 3 gigabytes per second. This is actually the most typical standard generally used in hard drive controllers now. The ATA interface made it feasible for RAID servers home might hard disk drives to be created to save data. These became quite popular. In 2007, Hitachi GST reached the milestone of creating the very first terabyte hard drive in the Deskstar 7K1000. It would really be only an issue of a couple years later in 2012 if the first four terabyte drive was produced by each of the three important hard drive manufacturers: Seagate, Western Digital, and Toshiba. These manufacturers now control a

business which has seen numerous competitors come and go over the years.
