All About Hard Drives

All About Hard Drives. A Primer. What is a hard drive and why do you need it? In every computer there is a storage space, called a hard drive. The main hard drive of your computer stores the operating system for your computer as well as files of data, photos, videos, and other work and play and home files. Most drives have matured over the years through technology, by getting smaller, lighter, more efficient and durable, in many cases, their basic operating structure has also radically changed. There are four basic hard drives — PATA (IDE) drives, SATA drives, SSD drives and NVMe drives.


PATA drive. Also known as IDE or EIDE drives, these are the older drives that used to run especially desktop computers.The initials "ATA" stand for Advanced Technology Attachment and PATA means Parallel Advanced Technology Attachment. These were mostly designed by Western Digital. Western Digital, Seagate and other familiar names are on them. They come in two sizes, a 3.5 inch drive and a 2.5 inch drive for laptops. Actually, the 3.5 inch is dimensionally, 4 x 5.75 x 1, but  the innards are 3.5 in across. The drive has a spinning platter inside with an electronic needle that moves across the platter as you are writing and reading data from your computer. It looks like a CD (remember those?) These drives have on the outside mostly a 40-pin connector with an additional 6 or 8 dual pin combination to tell the computer if the drive is a "master" or a "slave" to another drive on the computer. (See Example Below). As you can imagine, as data is written on the drive platter, the data can become scattered or "fragmented," and often for faster drive access and use, we need to "defragment" them. They are generally the slowest of all drives, reading and writing at up to 100 or 133 MB per second, which may seem fast, but is fairly slow according to modern standards. The larger the drive, the slower the access.


SATA drive. These are  the daughter of PATA drives and is what are used in most computers today. They are faster than PATA drives, and can read and write up to 16 GB per second, as contrasted with up to 133 MB per second with PATA. SATA attachment cables are also longer than the maximum 18 inch cable with PATA and therefore can be placed within the computer frame at a more convenient place. SATA offers two connection points, one to the drive and the other to the motherboard of the computer. Again, data is written to a moving platter and therefore can become fragmented over time. They are generally less expensive than the drives that followed them. SATA drives can be purchased in large storage sizes. (See Examples Below)


SSD drive. SSD stands for Solid State Drive. These drives have no moving parts and all data is stored on non-volatile memory chips. These drive can be anywhere from 120 GB to over 2 GB in size. These drives are the preferable 2.5 inch drives found in laptops and since they have no moving parts can withstand shocks much better. They are more expensive, perhaps two to four times as much as regular SATA drives. The connection is still a SATA connection to your computer. (See Examples Below)


NVMe drive. Released in 2013, NVMe drives (Non-Volatile Memory Express) are usually attached to a PCI Express (PCIe) slot on the main board of your computer. They are incredibly fast drives with read and write speeds of 32 GB per second and upwards. They are mostly used for gaming and high resolution video editing on the computer. They are very expensive and used for high end work. (See Examples Below)

Industrial Revolution and Display Typography (1800–1870) I have recently viewed the broadcasts of Great Canal Journeys, a narrated insight into Britain’s canals and waterways by two married and retired actors. They have been responsible for the restoration of a number of Britain’s canal systems. They noted that the Industrial Revolution in that country brought about the almost demise of the canals for moving products across the continent. The railroads took over much of the movement of goods from one place to another. In much the same way, typography and printing were forever transformed by the Industrial Revolution. Britannica notes that “the Industrial Revolution changed the course of printing and typography not only by mechanizing a handicraft but also by greatly increasing the market for its wares. Inventors in the nineteenth century, in order to produce enough reading matter for a constantly growing and ever more literate population, had to solve a series of problems in paper production, composition, printing, and binding.”

Advances in Typography (1500–1900) A Historical Sketch (Part 1) Early Renaissance (1500–1550) We had noted in the Blog “What Happened After Gutenberg: 1460–1640” (November 8, 2025) that movable type spread across Europe beyond its German roots. Gothic Blackletter type, though still used for religious and legal documents, began to give way to Venetian old style humanist faces. Influenced by humanist handwriting and calligraphy, Aldus Manutius and Francesco Griffo developed italic type for compact books. National printing centers became established in Venice, Italy, Paris and Lyon, France, Basel, Germany and Antwerp in the Netherlands The transition from Gothic to Italic typefaces was part of the broader evolution of typography that took place during the Renaissance period, driven by shifts in cultural, aesthetic, and technological factors. The Renaissance, beginning in Italy in the fourteenth century, marked a revival of classical antiquity and a move toward humanism. This brought a renewed interest in the legible, flowing scripts of Roman and Greek antiquity, which were more readable and aesthetically simple compared to Gothic lettering. The development of the printing press (ca. 1440) by Johannes Gutenberg created a need for more versatile and legible typefaces. The emerging humanist values aligned with a preference for typefaces that resembled the clear, round, and graceful writing of ancient Roman scripts.\ The Italic typeface was introduced by Aldus Manutius in Venice around 1501. Italic type is a cursive font based on a stylized form of calligraphic handwriting. Along with Blackletter (See Blog Jan 16, 2025 Blackletter Type and Universities) and roman type, italic has served as one of the major typefaces in the history of Western typography. Italics takes notable influences from hand drawn calligraphy, with italic letters normally slanted slightly to the right. Upper case letters may have typographic swashes, flourishes inspired by ornate calligraphy. The name “italic” comes from their Italian use, to replace documents traditionally written in a hand-written style called chancery hand. Notice also the small “end point bowls” on some of the letters, where the ink pen stopped for a second. While modern italics are often more condensed than roman types, historian Harry Carter describes Manutius' italic as about the same width as roman type. To replicate handwriting, Griffo cut at least sixty-five tied letters (ligatures) in the Aldine Dante and Virgil of 1501. Italic typefaces of the following century used varying but reduced numbers of ligatures. Manutius sought to create more compressed elegant typefaces that could fit more text on a page, catering to the rising demand for smaller, portable books. Italic was based on the handwriting of Niccolò de’ Niccoli, a Renaissance scholar and calligrapher. Italic typefaces are defined by their slanted, cursive-like appearance, with letters that have a flowing, dynamic quality. It allowed for more text to be fitted on the page and mimicked the handwriting style of humanist scholars, like the handwriting of Petrarch. The common italic “slope” was introduced in the sixteenth century — “The first printer known to have used them was Johann or Johannes Singriener in Vienna in 1524, and the practice spread to Germany, France and Belgium. Particularly influential in the switch to sloped capitals as a general practice was Robert Granjon, a prolific and extremely precise French punchcutter particularly renowned for his skill in cutting italics. Vervliet comments that among punchcutters in France "the main name associated with the change is Granjon's.” (Wikipedia on Italic Type) The insertion of an italic typeface alongside a roman face would wait until later to distinguish portions of a book not properly belonging to the work, such as introductions, prefaces, indexes, and notes; the text itself being in Roman. Later, it was used in the text for quotations ; and finally served the double part of emphasizing certain words. Italic type was not only more elegant than the Gothic but also more efficient in terms of space. It became the preferred choice for printed texts that emphasized classical learning, philosophy, poetry, and humanist literature. Italic was initially used for entire texts but later became more common for emphasis alongside Roman type.
