FAQ Section: Your SanDisk 120GB SSD Questions Answered
Q1: Why should I choose a 120GB SSD over a traditional hard drive (HDD) for my desktop?
A: A 120GB SSD, even with its smaller capacity, offers a massive performance upgrade over an HDD, especially for your operating system. You’ll experience dramatically faster boot times, quicker application launches, and an overall more responsive system. HDDs are good for bulk storage, but SSDs are kings of speed.
Q2: Is 120GB enough storage for my desktop PC?
A: It depends on your usage. For most users, 120GB is perfect for just the operating system (Windows takes up about 20-30GB) and essential programs. If you have many large games, video editing software, or a massive photo collection, you’ll likely need a secondary, larger drive (either another SSD or an HDD) for those files.
Q3: How do I install a SanDisk 120GB SSD in my desktop?
A: Installation is usually straightforward. You’ll need a SATA data cable and a SATA power cable (usually coming from your power supply). Many desktops have extra drive bays. Mount the SSD, connect the cables, and then you’ll either install a fresh operating system onto it or clone your existing OS from your old drive. There are many online tutorials and YouTube videos to guide you.
Q4: Are SanDisk SSDs reliable?
A: Yes, SanDisk is a well-established and reputable brand in the storage industry. Their SSDs are generally known for their good quality, performance, and durability. Like all electronics, failures can occur, but SanDisk stands behind its products with warranties.
Q5: What does “SATA III 6Gb/s” mean, and why is it important for a SanDisk 120GB SSD for desktop?
A: SATA III 6Gb/s (SATA 3.0) is the current standard interface for connecting SSDs and HDDs to your computer’s motherboard. “6Gb/s” refers to the maximum theoretical data transfer rate. It’s important because it ensures your SSD can communicate with your computer at optimal speeds, preventing a bottleneck in performance. Most modern desktops support SATA III.
Q6: Can I use a 120GB SSD alongside my existing hard drive?
A: Absolutely! This is a very common setup. You can install your operating system and frequently used applications on the 120GB SSD for maximum speed, and then use your larger, older HDD for storing documents, photos, videos, and less frequently accessed files. This gives you the best of both worlds: speed and capacity.
Q7: Will a 120GB SSD make my games load faster?
A: Yes, installing games on your 120GB SSD will significantly reduce game loading times compared to running them from an HDD. While it won’t directly improve in-game frame rates (that’s more about your CPU and GPU), the initial loading of levels, textures, and game assets will be much quicker.
