Warp Factor 9 Mr. Scott... SSD vs HDD

SSD vs HDD... What are they? ...and what's the difference?

According to Wikipedia an SSD (Solid State Drive) is: A solid-state drive (SSD, also known as a solid-state disk[1][2][3]) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology primarily uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives, which permit simple replacements in common applications.[4] Additionally, new I/O interfaces, like SATA Express and M.2 have been designed to address specific requirements of the SSD technology. SSDs have no moving mechanical components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) or floppy disks, which contain spinning disks and movable read/write heads.[5] Compared with electromechanical disks, SSDs are typically more resistant to physical shock, run silently, have lower access time, and lower latency.[6] However, while the price of SSDs has continued to decline over time,[7] consumer-grade SSDs are (as of 2016) still roughly four times more expensive per unit of storage than consumer-grade HDDs.[8]

According to Wikipedia a HDD (Hard Disk Drive) is: hard disk drive (HDD), hard diskhard drive or fixed disk[b] is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces.[2] Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile memory, retaining stored data even when powered off.

Now that's the tech bit out of the way...

Many existing computers and laptops come with HDD's pre-installed as they're cheaper and can offer large storage capacities on a budget. While HDD's are fine for most users once you've experienced the massively increased speeds of SSD's you won't want to go back to regular HDD's. Typically an SSD drive is 10x the speed of a HDD which makes this one of the most noticeable upgrades your computer or laptop can have fitted.

Most computers are capable of running on SSD drives though sometimes an adapter or bracket may be required. A consideration for laptops is that SSD drives use less battery power than regular HDD's which is a handy bonus, plus they're more durable if your laptop gets knocked or even dropped (even if the laptop doesn't survive the SSD probably will).

The downside of SSD's is the upside of HDD's, SSD's are much more expensive and space comes at a premium, typically a new laptop with an SSD drive will cost you an extra £200 with 1/4 of the space of its regular HDD counterpart, but the massive speed difference makes this still a desirable option.

Best of both worlds...

Hybrid drives SSHD or as Apple markets them "Fusion" Drives deliver the best of both worlds, combining SSD with HDD in one package. The SSHD delivers very nearly the speed of an SSD with the storage capacity of a HDD at a price point usually somewhere between the two. Hybrid or SSHD drives are perfect for people who want SSD speeds on a budget while not compromising on storage capacity.
