Normal Hard Disk/Drive vs Solid State Drive

Coronavirus quarantine Blog Post #8

Normal Hard Drive (HDD/Hard Disk Drive) vs Solid State Drive (SSD).


Most Modern Laptops use SSD's.  An SSD is basically a hard drive with no physical spinning disk and moving arm which reads the disk, which is what makes it so fast.  Think of an SSD like a giant SD Card.  On the other hand, an HDD has a spinning disk inside of it with a moving arm reading the disk, is more sensitive to movement, can be damaged if turned upsidedown or even slightly sideways, and can be damaged from rough movement.  HDD's are slower because the moving hand inside of the structure constantly moving on the spinning disk to read data and transmit it to a computer.  SSD's simply send data to a computer instantly instead of needing to read a spinning disk with a moving arm.  SSD's also have a longer lifespan.  90% of HDD's have a lifespan of about 3.5 years, and 80% have a lifespan of 4.5 years.  Almost every SSD has a lifespan of at least 7.5 years, while most have a lifespan of about 10 years.


Which should you get?:


Definitely an SSD.  If you have a very low budget that can only purchase a device with an HDD or just an HDD, remember to back up your data to somewhere like Microsoft OneDrive often, as your HDD Can fail by simply dropping your device, shaking it, tilting it sideways or putting it upsidedown, or exposing the actual HDD disk to the outside air.  If you drop an SSD, it will most likely not cause any damage.  If you shake, tilt sideways or upsidedown, or expose an SSD to air, it will not fail.

Starship SN10 Aborts at T - 0 Seconds for its 10km test flight.

  Moments ago, Starship SN10 attempted a flight to 10km, to then orient itself into a unique horizontal bellyflop position, flip itself upright after it has descended to about 1km, deploy the landing legs, and touch down on the landing pad softly. This vehicle, Starship Number 10, uses Liquid CH4 (methane) and Liquid Oxygen aka LOX/LO2, used by its 3 powerful Raptor engines.  Today, SpaceX started their official stream for the Starship SN10 Flight. SpaceX have privated the stream replay, so we cannot replay it. In case you want the link:  https://www.youtube.com/watch?v=DDEgFsefrGw&t=541s The vehicle began fueling up with Methane and LOX, and then shortly after, it started the engine chill process, which is the process of chilling the engines down in preparation for engine ignition, so the engine material does not crack or get damaged from sudden shock. The vehicle attempted to start up its 3 Raptor engines, by opening the fuel & oxidizer valves, starting up the turbopumps, sho

What is “the best” programming language?

Programming languages, there are so many of them. Some programming languages are way easier to learn than other ones. But which programming language, is “the best” programming language? This question, it is not really answerable. There is no “best programming languages”, they are all meant for different things, well, MOST of them. If I were to compare 2 different programming languages, meant for very similar things, like Batch and Bash, I would say Batch is easier, as its Syntax is not as confusing as Bash’s to the average person. Here is another example, C# is primarily used for computer applications, mostly on Windows, and HTML is a markup language, being used to make websites. I cannot compare C# (it is pronounced “See Sharp” if you didn’t know) because they are used for completely different things. It wouldn’t make sense to say, “C# is way better”, because what is it better at? Developing desktop applications? Sure! Then I can say HTML is better at making websites, it is not a logi

How do you know the universe was not created a few minutes ago?

       The universe is the giant area of space that we live in, which is observable. Anything past our universal border is not in our universe. People do say the universe is constantly expanding, but there is no proof of that, as the "imaginary" or, maybe not imaginary border at the "end" of our universe. But, how do you know that the universe even exists? Were you even in it last week? Did last week even exist? Last week, the universe could have been created, and you do not have proof against it. All of your knowledge and memory could have easily popped into existence a few seconds ago, tricking you into thinking you have existed for longer than you think. This is likely, but also unlikely, it is a 50/50 chance. A reason that this is unlikely is, there are a lot of things that do not make sense in our universe. Like, why does matter attract matter, resulting in gravity? This exists in our universe, but can it exist in a different universe? Not really, or most likel
