Frequently Asked Questions (FAQ)
Finding the right SSD can sometimes feel like wading through alphabet soup. Here are some common questions answered to help you out!
Q1: What is an SSD, and why should I get one for my PC?
A1: An SSD (Solid State Drive) is a modern storage device that uses flash memory to store data, unlike traditional HDDs (Hard Disk Drives) which use spinning platters. This means SSDs have no moving parts, making them significantly faster, more durable, quieter, and more energy-efficient. Upgrading to an SSD, even a 120GB one, will drastically improve your PC’s boot times, application loading speeds, and overall system responsiveness.
Q2: Is 120GB SSD capacity enough for my PC?
A2: A 120GB or 128GB SSD is generally enough if you primarily use it as a boot drive for your operating system (Windows/macOS) and a few essential programs (like your web browser, office suite, etc.). However, if you plan to install many large games, creative applications, or store a lot of media files, you’ll quickly run out of space. In such cases, consider a larger SSD (256GB or 512GB) or combine it with a secondary, larger HDD for data storage.
Q3: What’s the difference between SATA and NVMe SSDs?
A3: SATA (Serial ATA) and NVMe (Non-Volatile Memory Express) are different interfaces for connecting SSDs. SATA SSDs (like the Lexar NS100 series) use the same interface as traditional HDDs, offering speeds up to around 550MB/s. NVMe SSDs (like the Lexar NM1090 or NM790) connect via the PCIe slot, providing much higher speeds, often reaching thousands of MB/s. NVMe is ideal for high-performance tasks, gaming, and professional workloads, while SATA is a more affordable and still very fast option for general use.
Q4: How do I install an internal SSD in my desktop or laptop?
A4: For a 2.5-inch SATA SSD, installation usually involves opening your PC case (or laptop panel), connecting the SSD to a SATA data cable and a SATA power cable (for desktops) or sliding it into an available 2.5-inch drive bay (for laptops). For M.2 NVMe SSDs, you’ll need an M.2 slot on your motherboard, where the drive slides in and is secured with a small screw. After physical installation, you’ll need to initialize the drive in Windows Disk Management or clone your old drive’s OS to the new SSD. Always back up your data first and refer to your PC’s manual or online tutorials for specific instructions.
Q5: Are Lexar SSDs reliable?
A5: Yes, Lexar is a well-established brand in the memory and storage industry, known for producing reliable and performance-oriented products. Their SSDs often come with decent warranties (like three or five years), indicating their confidence in product longevity and quality. User reviews generally reflect positive experiences regarding their reliability and performance.
Q6: What does TBW (Terabytes Written) mean for an SSD?
A6: TBW stands for Terabytes Written and is an endurance rating for SSDs. It indicates the total amount of data that can be written to the SSD over its lifetime before its reliability might start to degrade. For example, a 60TBW rating means the drive is expected to handle 60 terabytes of data written to it. For average users, even lower TBW ratings are more than sufficient for many years of typical use. Higher TBW ratings are important for power users, servers, or applications with extremely heavy write cycles.
Q7: Can I use an external SSD for my PC to improve performance?
A7: An external SSD (like the Lexar ES3 or Armor 700 series) can significantly improve performance for certain tasks, such as storing and accessing large media files, running portable applications, or performing quick backups, much faster than an external HDD. However, it cannot serve as your primary boot drive to speed up your operating system’s startup, as it connects via USB, which is typically slower than internal SATA or NVMe connections. For an OS speed boost, an internal SSD is what you need.
