FAQs About 500GB SSDs Under $100
Q1: What’s the main difference between an internal and external SSD?
A1: Internal SSDs (like the Samsung 870 EVO or 980) are installed inside your computer, typically replacing a hard drive or acting as a secondary drive. External SSDs (like the SanDisk Extreme or BUFFALO) connect via a USB cable, offering portable storage that you can plug into different devices.
Q2: SATA vs. NVMe: Which one should I choose?
A2: SATA SSDs are generally more affordable and are great for older systems or as a secondary storage drive. They offer speeds far superior to traditional hard drives. NVMe SSDs, on the other hand, are much faster, connecting directly to your motherboard via a PCIe slot (often M.2 form factor). If your system supports NVMe, it’s the ideal choice for primary storage due to its incredible speed.
Q3: Are 500GB SSDs enough storage for most users?
A3: For many users, 500GB is a good sweet spot. It’s usually enough for the operating system, essential applications, and a decent amount of files, photos, or even a few large games. If you have extensive media libraries or a massive game collection, you might consider a larger drive or supplementing with external storage.
Q4: Can I install an internal SSD myself?
A4: Yes, for most users, installing a 2.5-inch SATA SSD in a desktop or laptop is a fairly straightforward process, often involving just a few screws and cables. M.2 NVMe SSDs are even simpler, typically just slotting into place. Many online tutorials can guide you through the process step-by-step.
Q5: What does “TBW” mean, and why is it important for SSDs?
A5: TBW stands for “Terabytes Written,” and it’s a measure of an SSD’s endurance. It indicates the total amount of data that can be written to the drive before its warranty or expected lifespan is reached. A higher TBW means the drive is rated for more writes and generally has a longer lifespan. For example, 600 TBW means you can write 600 terabytes of data to the drive over its lifetime.
Q6: Will an SSD really make my old computer faster?
A6: Absolutely! Upgrading from a traditional hard drive (HDD) to an SSD is often the single most impactful upgrade you can make to an older computer. You’ll notice significantly faster boot times, quicker application loading, and overall snappier system responsiveness, even if your processor and RAM are older.
Q7: Can I use an external 500GB SSD to store games for my PS5 or Xbox Series X/S?
A7: Yes, you can! For current-gen consoles like the PS5 and Xbox Series X/S, external SSDs are great for storing older generation games (PS4, Xbox One, etc.) or for backing up current-gen games. While you can’t play next-gen games directly from most external SSDs (unless specified by the console manufacturer for expansion slots), they’re fantastic for expanding your overall game library and reducing internal storage clutter.
Final Thoughts
Finding the best 500gb SSD under 100 doesn’t have to be a daunting task. As you can see, there are plenty of excellent options available, whether you need a super-fast internal NVMe drive, a reliable SATA workhorse, or a rugged portable solution. Each of these SSDs offers fantastic value, promising to significantly enhance your computing experience without breaking the bank. So go ahead, pick the one that best fits your needs, and enjoy the speed!
