What is the best kind of computer?🖥
The short answer: One with the most amount of RAM you can afford, touchscreen if it's a laptop, and with the largest hard-drive you can afford. I think for my purposes (everyday use, not strictly concerned with long-term data storage) I would choose an SSHD (Hybrid) for a nice blend of the speed from a SSD (solid-state (flash) drive) and the long-term storage of a HDD (hard disk (mechanical) drive. See below for more detailed information of each aspect that might concern you when buying a computer!

Easy Guide to Important Aspects when Buying a Computer
Here we delve into some of the can be confusing parts of purchasing a computer. We know you want the most RAM, and here we'll go over "What's the Difference between a mechanical (regular) hard-drive and a SSD or solid-state drive. And when might I choose one over the other?" Those questions answered as well as information for what has always been the most complex part of choosing a computer to buy - to me: processors and what their differences are. This page will focus some on laptops but the things I've mentioned go for both Laptops and Desktop Computers.
𓄃 RAM
(Random Access Memory) RAM is computer memory that stores data temporarily while a computer is running and is easier and quicker to access than hard-drive.
The Basics: You want as much RAM for your money. Why is that? What does RAM do? Having more RAM (Random Access Memory) provides several benefits, particularly in terms of performance, multitasking, preventing crashes, and future-proofing your purchase.
Here's why more RAM is desirable?
It improves multi-tasking. RAM allows your system to run multiple applications simultaneously without slowing down; For those times when you want to browse the web with multiple tabs open, run video editing software, and listen to music at the same time without performance issues.
It also gives you faster performance. When your computer has sufficient RAM, it can store more data in its high-speed memory, reducing the need to rely on slower storage like an HDD or SSD. This speeds up tasks like loading applications, switching between programs, and opening large files - less time wasted and/or getting aggravated at lack-luster performance.
For those whom want to use their laptop or desktop for gaming (desktop is suggested more for gaming as the components required to play high-taxing games often have over-heating issues in laptops as opposed to desktops unless specifically built for gaming. Many modern games require significant amounts of RAM to run smoothly. Insufficient RAM can result in stuttering, slower load times, and poor frame rates.
When handling large files, tasks like video editing, 3D rendering, and working with large spreadsheets or databases, more RAM is essential to manage the data efficiently (keep everything running smoothly).
Sufficient RAM is also necessary as it low RAM can cause your system to freeze, crash, or display error messages when it runs out of memory while performing demanding tasks.
Future-Proofing
Besides all these above mentioned important reasons, you want your investment to stay viable as long as possible. As software and operating systems become more advanced, their memory requirements increase. Having more RAM ensures your system can handle future updates and applications and you're not re-buying what you've just invested in - that your purchase sticks around for a while before becoming obsolete.
These are the reasons when considering a computer, I always look at RAM first. It's got to be capable. I can't fight with or beg a computer to do tasks. Ain't nobody got time for that!
Bonus tip:
If you run virtual machines (e.g., for software development or testing), each instance requires its own portion of RAM. More RAM allows you to run multiple virtual machines simultaneously.
How Much RAM Do You Need?!
- 4GB: Basic tasks like web browsing, word processing, and email (minimal multitasking).
- 8GB: Moderate multitasking, casual gaming, and general use.
- 16GB: Professional work (video editing, graphic design), gaming, and heavy multitasking.
- 32GB or more: High-end gaming, 3D rendering, simulations, and running multiple virtual machines.
To sum it all up, more RAM enables smoother, faster, and more efficient operation, especially for demanding tasks and modern software. And more of it is an aspect of future-proofing your technology.

The first thing I do when looking to buy a laptop is look at RAM. That is going to prevent the computer from being sluggish. Even before that, after being spoiled to the acer touchscreen I got in college... I will never (if I have a choice) go back. It's so handy to be able to lean in while working and touch the screen. I also noticed another benefit: that if the webpage I was on was freezing, often times I could still move the page, and navigate using touch. I do not like to be slowed down when working. Solid-state drives since their invention have always been recognized as being superior, especially in laptops as with a mechanical hard-drive you've got moving parts and sometimes when you're moving a laptop around, I've heard grinding from the spinning disk and the parts of the harddrive that writes to it.
Backlit keyboards, aside from looking sweet, are handy when working in the dark.
My last consideration, and preference when it comes to laptops is unless it comes in white, I like a dark-colored laptop so it kind of fades away while I'm watching movies on my laptop.

Worried about the recoverability of data stored on drives?
How HDDs and SSDs measure up in terms of Data Recovery
Yes, HDDs (Hard Disk Drives) are generally better for data recovery compared to SSDs and SSHDs, though this depends on the nature of the failure. Here’s a detailed explanation:
Why HDDs Are Better for Data Recovery
-
Recoverability of Deleted Data
- On HDDs, when you delete a file, the data itself isn’t erased immediately; only the file’s reference in the file system is removed. This makes it possible to recover the data until it’s overwritten.
- Specialized data recovery software can scan the disk to reconstruct these files.
-
Predictable Failures
- HDD failures, especially mechanical ones, often provide warning signs (e.g., unusual noises, slow access times). This allows for proactive recovery before total failure.
- Even in cases of mechanical failure, data can often be recovered by repairing or replacing faulty parts in a clean room environment.
-
Physical Data Location
- Data is stored magnetically on spinning platters in a sequential and predictable manner, making it easier for experts to retrieve data even if part of the disk is damaged.
-
Fragmentation Tolerance
- While fragmentation can reduce performance, it doesn’t usually result in permanent data loss. Recovery tools can piece together fragmented data.
Challenges with SSD Data Recovery
-
TRIM Command
- Most SSDs use the TRIM command, which immediately erases data when a file is deleted to maintain drive performance. This makes traditional data recovery methods ineffective.
- Once TRIM has been executed, recovering the deleted data is almost impossible.
-
Wear-Leveling Algorithms
- SSDs use wear-leveling to distribute data evenly across memory cells. This makes it harder to locate specific pieces of data during recovery.
-
Data Loss During Failure
- SSDs tend to fail suddenly and completely, often due to controller or firmware issues. When this happens, data recovery is much more difficult compared to mechanical failures in HDDs.
SSHDs (Solid State Hybrid Drives)
- Complexity: SSHDs combine an HDD and SSD, meaning the data could be stored on either the magnetic platters or the flash memory. This complexity can make data recovery more challenging.
- Limited Flash Access: Recovery from the SSD portion of an SSHD faces similar issues as with standalone SSDs.
When HDDs Are Better
- Physical Damage: Data recovery professionals can often repair mechanical parts or extract data directly from the platters.
- Deleted Files: Recovering deleted files is straightforward unless the data has been overwritten.
When SSDs Are Better
- No Moving Parts: SSDs are immune to mechanical failure, so they are less likely to need recovery from physical damage.
- Durability: For situations where physical shock or vibration is a concern, SSDs are less likely to fail in the first place.
Conclusion
- HDDs are better for data recovery in most scenarios because their data storage methods and failure modes are more accessible to recovery tools and techniques.
- SSDs, while more durable, can be challenging to recover from due to TRIM, wear-leveling, and sudden failure risks.
- For critical data, regular backups are the best way to ensure recovery, regardless of the drive type.
