For the past few years, solid-state drives (SSDs) have become quite popular in the computing world, mostly because of how fast they are compared to hard disk drives (HDDs). So, what exactly sets an SSD apart from an HDD?
Nowadays, computers use non-volatile medium for storage, which means data that’s stored in it doesn’t get lost once the computer shuts down. Storage for modern-day computers and notebooks have been handled by hard disk drives for the longest time and it’s only now, with SSDs becoming more affordable, that consumers are seeing a different storage medium in their computers.
Hard disk drives have mechanical parts
If you aren’t familiar, hard disk drives store data on circular disks made up of aluminum, glass, or ceramic that are coated with a magnetic layer, often called platters. Since these platters are responsible for holding the data, the storage capacity of an HDD is dependent on how many platters it has.
When the computer’s processor sends out instructions to read and write data, the motor on the drive moves the actuator arm across the platter. At the end of the actuator arm are the read/write heads which are made up of tiny magnets responsible for reading data already stored on the platter or writing new data on the empty spaces on the platter. The combined movement of the actuator arm and the rotation of the platter allows the computer to read and write data, which is kind of like the arm of a record player touching a vinyl record to play music.
Having all these moving parts means an HDD’s read and write speed is dependent on how fast the platters can rotate and how fast the actuator arm can track locations on the platter. These parts can only move up to a certain speed or else they’ll break down, and nobody wants a broken storage device. As with all mechanical parts, heat and noise are by-products of their movements, which is why an HDD can become hot and/or noisy during operation.
Solid-state drives have no moving parts
From its name, an SSD is a drive that uses a type of solid-state storage called flash memory, which is also a non-volatile storage medium, to store and retrieve data. Each flash memory chip found in the circuit board of an SSD contains memory cells that are made up of floating-gate transistors, which are a special type of transistor that can store or discharge an electrical charge in its cage-like part called the floating gate. The storing capability of these transistors is what allows the data to remain, even when there’s no electricity flowing through them.
As mentioned, an SSD doesn’t have moving parts like the actuator arm and motors of an HDD. Instead, it has an embedded processor called a controller. Much like the computer’s processor, the controller does all the heavy lifting, as it’s the one responsible for locating the blocks of memory where data can be read or written to.
This is also the reason why SSDs perform faster than HDDs; since they don’t need to wait for any moving parts to read or write data, the controller just needs to receive the instructions from the computer’s processor and it can start reading or writing data.
SSDs may not suffer from a mechanical breakdown, but they’re far from faultless. Flash memory can only have data written and erased a finite number of times before its cells degrade and become unreliable. This means an SSD can only write a certain amount of data before it fails, which is why SSD specification sheets typically include Terabytes Written (TBW), so consumers know how much data can be written into the drive before it eventually fails. However, SSDs these days can last more than ten years in typical day-to-day usage.
Both storage mediums have pros and cons
So, is a solid-state drive better than a hard disk drive, or vice-versa? Sadly, there’s no simple answer to this question, as it all depends on the needs of the consumer, which usually involves speed and storage capacity.
On one hand, if a person wants faster read/write times, an SSD is the clear winner, but you’ll lose out on storage capacity, since most SSDs today start from 120GB and can only go up to 1TB or 2TB. Mind you, those high-capacity SSDs will surely burn a big hole in your wallet.
On the other hand, if a person values capacity more, an HDD is the better option, with drives typically ranging from 500GB to 6TB of storage capacity for mainstream HDDs. Also, HDDs don’t cost an arm and a leg compared to SSDs if you want to get large-capacity ones.
With these in mind, there’s no stopping consumers from having both an SSD and an HDD in the same system. Setting up an SSD as your main drive with the operating system and other important software, while having a secondary HDD to store all your media and personal files, would net you the best of both worlds: a speedy system boot up without sacrificing storage space.

What you need to know about Elon Musk’s Starlink
The much-awaited internet service is coming sooner than later
Over the last few weeks, reports started pouring in about the possible arrival of Starlink internet service to the Philippines under a partnership between Converge ICT and SpaceX. These reports came after a senator’s meeting with representatives of SpaceX discussing the benefits, possible timeline, and requirements needed from the internet service.
These reports quickly became the talk of the town especially with the frenzy surrounding Starlink. You may have heard it before given the media attention it had received in the past. SpaceX — the company behind Starlink — promised fast network speeds and coverage almost anywhere around the planet with its internet service. There’s so much more to that though, so here are the things you need to know.
What is Starlink?
For those out of the loop, Starlink is a satellite internet service provided by SpaceX. SpaceX is a company founded by Elon Musk that builds next-gen space exploration technologies. The company is also behind the high-profile launches of reusable rockets as well its plans to bring people to Mars.
Starlink works through a constellation of small satellites. These satellites are placed in low to medium Earth orbit, communicating signals through an array of antennas and lasers. They work in tandem with dedicated ground transceivers to receive from and transmit signals to the satellites. In effect, the internet service relies on satellites instead of physical cables to provide an internet connection to consumers.
The technology behind Starlink is not a novel one, with the first satellite internet service dating back to the 1990s. However, most of these services ultimately failed due to logistical constraints and the prohibitive costs involved in setting things up. Granted, there had been few services that have seen some success but their adoption is few and far between. Reducing latency and lowering costs for consumers remain major challenges to many satellite internet providers.
Wanting to improve the whole situation, SpaceX began product development of Starlink in 2015. By 2018, it began testing its satellites which culminated in the launch of operational ones last 2019. Just last year, the company reached a milestone by launching up to 60 satellites at a time. This 2021, it is setting its sights for the global coverage of the populated world. Ultimately, SpaceX aims to put about 42,000 satellites in orbit in the future.
One goal of Starlink is to provide people in remote areas with a fast and reliable internet connection, which means a lot for developing countries like the Philippines.
How do I sign-up for the service?
Right now, the company is offering a limited beta service in the US and Canada. If you live in areas where the service is available, you can go ahead and sign-up for the service on Starlink’s website. Not all who signed up can avail of the service though since they are limiting their users at the moment on a first-come, first-serve basis. If you’re lucky, you may receive an email containing further instructions.
What does it feel like to use the service?
During its beta phase, Starlink claims speeds of 50 to 150 Mbps. Latency — which is also a crucial factor in internet-related tasks such as gaming and streaming — ranges from 20ms to 40ms. These figures are far from the advertised 1Gbps speed, as well as the advertised latency of 25ms to 35ms.
Still, those figures are fast enough for everyday use, especially when compared to other satellite internet services. Those figures are also close to the actual experiences by people participating in the limited beta service. For its part, Starlink promises continued improvement to network speed, latency, and software.
At the moment, the cost of signing up for Starlink is much higher than availing of a cable internet connection. The satellite setup kit is reported to cost around US$ 499 (PhP 24,000) while monthly fees start at US$ 99 (PhP 5,000). In comparison, PLDT’s internet plans max out at PhP 6,099 for 300Mbps while Globe’s internet plans max out at PhP 9,499 for 1Gbps.
To get connected, Starlink users must configure their setup kits and download the respective app. Each setup kit consists of the satellite dish, Wi-Fi router, power supply, cables, and a mounting tripod.
A clear view of the sky is also a prerequisite for a stable connection. As a note, weather disturbances can affect the connection between the user and the satellite infrastructure.
Starlink also requires its setup equipment to be stationary at all times. This is unlike cellular networks, which are designed to be mobile. While it offers a “wireless” connection to the internet, it still is “fixed” in the sense that it requires constant communication between the transceiver (the satellite dish) and the orbiting satellites.
When is it really coming to the Philippines?
Recent reports suggest that Starlink is coming soon to the country, but no definitive timeline has been given. Rumors suggested that the service will arrive later in Q3 2021. The most recent development squash any hopes of imminent arrival though, with Converge ICT stating that the partnership is still “premature”.
During the later weeks of February, however, Filipinos who signed up for Starlink started receiving a reservation email. The reservation fee costs around US$ 99 (approximately PhP 5,000) though it is fully refundable too. The email also details a possible coverage of the whole country by 2022. The exact date, however, remains unclear at the moment.
Likewise, the internet service still has many obstacles towards its widespread adoption in the country. The initial cost for would-be subscribers comes to mind. As mentioned, the approximate cost of Starlink hovers at PhP 24,000 with a monthly fee amounting to PhP 5,000. For that cost, you are getting better speeds with local telco offerings.
Despite its high cost, the promise of a fast and reliable internet connection is tempting especially in far-flung areas. Reaching out to these far-flung areas is a major challenge for all local telcos since the necessary physical infrastructure is non-existent or hard to setup. Starlink could reach these areas easily, providing internet connection to those willing to shell out money.
Are there any other things that I should know about the service?
Starlink has garnered some concerns as well, with most directed towards its potential to cause light pollution. The potential to contribute to light pollution is a particular concern for astronomers. Apparently, Starlink’s satellites are bright enough to leave a trail of light, “photobombing” shots of the night sky. To this end, SpaceX said that it is already working on a solution to amend the problem.
As Starlink continues to push forward, more and more people are hoping to get aboard with the service. After all, a fast and reliable internet connection is still far from reality for many people living in remote areas. Hopefully, the service would come sooner as this will greatly improve the current situation of the internet in the Philippines.
The industry’s next big thing: Cloud gaming explained
It’s gaming on the go, but for internet that’s not slow
Everybody’s getting into gaming these days, and you can’t blame them. With the pandemic continuing its ravaging ways in the world, people turn to their consoles or PCs for some action. However, not everyone can afford all the expensive PCs and the next-gen consoles when they come out.
Instead, a new player comes into the fray with a pretty great idea. What would happen if you can just play your favorite games from any device? Also, what if we told you that this won’t take up space on your device at all? This is basically what cloud gaming offers to you: a way to play games from any device at any time!
So, how does that actually work? What do you need to ensure quality gameplay, and should you even consider it?
The basics of playing on a cloud
On paper, it’s pretty easy to understand how cloud gaming works. Basically, you have access to a library of games from a cloud storage service. When you subscribe to the service, you can virtually play your library from any device regardless of the specs. Also, you don’t have to worry about storage problems since these games are stored on a server.
It’s no joke when these companies tell you that you can play your games on any device. With their dedicated data servers, they make sure that the games run smoothly once you access them from the cloud. On your end, you will need a strong and consistent internet connection to play the games smoothly.
Several companies already have cloud gaming software available for people to subscribe to. Some examples include NVIDIA’s GeForce Now, Microsoft’s xCloud, and Google Stadia — all of which store PC games on a server. These companies even take the time to update their server hardware every so often to bring the best possible quality.
System requirements for cloud gaming
Much like your ordinary PC or gaming console, companies that run cloud gaming servers need certain equipment to run smoothly. First, these companies must set up active data centers and server farms that run the games. These data centers ensure that games are up and running, while reducing latency. In other words, these serve as the powerhouse of cloud gaming.
Next on the list is the network infrastructure necessary to send these to the users. To ensure that people don’t experience lags when they play their games, companies also invest in acquiring proper data connections. However, in most cases, this isn’t something these companies have control over; it’s mostly coming from their available internet service providers.
On the front-end, companies also provide dedicated hardware and software to house the cloud. For example, NVIDIA integrated GeForce Now into their own cloud streaming device, the NVIDIA Shield back in 2013. Meanwhile, Google Stadia relies heavily on using pre-existing Google software like Google Chrome and the Stadia App.
Something great to offer, for the most part
Cloud gaming services offer something unique in the industry. Essentially, it eliminates the user from investing so much into buying expensive PCs as it allows people to play from virtually any device. Whether it’s on a smartphone, laptop, or even a smart TV, people get access to games at high frame rates without an RTX 3080.
Furthermore, the game and save files are stored on the cloud, and don’t take up any storage on your devices. This is greatly beneficial for people who are already running on limited storage space, especially if they play Call of Duty: Warzone. With everything stored on the cloud, you don’t need most of the 512GB of SSD storage.
However, one of the biggest issues with cloud gaming revolves around the thing it’s based on: the internet. Specifically, it’s on the user’s internet connection as these services require the fastest internet to run smoothly on any device. Basically, you will need either an Ethernet or a 5G wireless connection to ensure the lowest latency possible.
That infrastructure isn’t readily available in most markets, which is a prominent issue among several third-world countries. Furthermore, even if there are companies that have 5G in their pipeline, these same providers also put data caps on it. Even if the user can play at an optimal frame rate, they’re doing so with a restriction in place.
Does this new player have any place?
With the world continuously opening its arms to the gaming industry, innovation becomes the forefront of success. Companies come up with a variety of gaming technologies that seek to cater to a wide variety of people. From individual hardware to pre-built systems, gaming often revolved around these things.
With cloud gaming, it gives people not just another option within the mix. Rather, it seeks to challenge the notion of availability and accessibility, and give it a viable solution. Essentially, it takes away the physical hardware limitations on the user’s end, and makes it available for everyone.
But like most gaming technologies, everything is still limited somehow. These systems still experience bottlenecks both on the manufacturer and the user’s end. In the end, it will depend on how much you’re willing to shell out for them, and how willing you are to accept the risks.
Your MagSafe Questions Answered
Do you really need it?
If you’ve ever owned an old MacBook before, you’ll know that those chargers magnetically snap onto place. That particular technology is called the ‘MagSafe’.
The MagSafe technology might not be new but the implementation for the latest iPhones makes the technology even more usable. Other than the securely-placed phone for wireless charging, there are a plethora of case manufacturers who continuously work on future accessories that support MagSafe existing ecosystem.
But is the Apple MagSafe more than just a gimmick? And do you really need it?
