Other SSD benefits include its lack of moving parts and the ability to withstand rough treatment. Keep in mind, however, that SSDs do get slower over time. SSD desktops and laptops boot up significantly quicker than comparable systems fitted with hard disk drives. People most concerned with speed usually prefer an SSD-equipped system, as they run about 100 times faster than HDD machines. Whether or not an SSD or HDD is the better option is situation dependent. The higher the speed, the faster the drive can read and write data. On consumer computers, the platters typically spin between 4200 rpm and 7200 rpm. Tracks are further divided into sectors, and algorithms handle data processing. They’re also equipped with an I/O controller and firmware that facilitates communication with the rest of the computer.Įach of the magnetic platters is comprised of concentric circles called tracks. HDDs contain an actuator arm fitted with a read-write head, one or more magnetic platters and a motor. Over the decades, however, they’ve hued to Moore’s law. In those early years, when computers were the size of large lockers, HDDs were gigantic.
A near instant success, hard disk drives quickly became the preferred method for digital storage. International Business Machines (IBM) invented HDD technology back in the 1950s. HDDs use magnetic storage technology in conjunction with rotating platters and an actuator arm to write new data and retrieve stored information. However, unlike RAM, data written onto a solid-state drive remains even in the event of a power loss.
The actual SSD technology is similar to RAM. SSDs do not require revolving disks or actuator arms to initiate a process. Pages are further configured into “blocks,” which represent groups of information. Grids are divided into sections called “pages” where data is written and stored. Solid-state drives are comprised of semiconductor flash chips arranged in an integrated circuit grid. Solid-state drives are called such because they don’t have any moving parts, making them more reliable than their HDD counterparts. Today, some SSDs achieve speeds of 3500 megabytes per second. was offering DRAM-based products marketed as “RAMDisk.” The first laptop to incorporate SSD technology was IBM’s ThinkPad in 1991, which included a 20 megabyte SSD developed by SunDisk Corporation. In time, engineers switched to a dynamic random-access memory protocol, and by the late 1980s Zitel Inc. A technological marvel of its time, the STC 4305 was seven times faster than HDDs and cost half the price. Manufactured by StorageTek, the STC 4305 hit the scene in 1978 and is considered the first SSD. Instead, solid-state devices rely on integrated circuit memory technology. Some people use the term solid-state disk, but that’s a bit of a misnomer since SSDs don’t use disks.

The Rocket Pro is another excellent choice.Īnd if you have a spare desktop drive gathering dust doing nothing, why not use something like the Satechi DIY enclosure to repurpose it as a portable, USB-C equipped SSD.SSD stands for solid-state drive. There are plenty of other good choices out there as well with a special shout out for Sabrent, a brand you may not be familiar with, but that has been producing some good quality, high performing, affordable storage solutions recently. The T7, in particular, is insanely portable, sizing little more than a credit card. Like Samsung internal storage, the T7 is fast, reliable, good value and comes with a solid warranty. If we had to choose one we'd always lean towards, it would be the Samsung T7, for similar reasons to recommending the company's internal SSDs.
An SSD is by far the best way to do this, and with the advancement of the USB-C standard, prices are beginning to fall.

From $170 at Amazon Plenty of great choiceĮven with cloud storage as ubiquitous as it is today, sometimes you simply can't substitute being able to carry data with you on a portable drive. Backed up by a five-year warranty and optional hardware encryption, this really is an SSD you can take anywhere. It's IP55 rated, can survive a two meter drop and the aluminum chassis has also been designed to act as a heatsink to ensure maximum performance for longer. SanDisk has wrapped up an NVMe SSD inside a rugged, but tiny case, and paired it with USB-C 3.2 for fast, but accessible data transfer speeds.
