Frequently Asked Questions (FAQ)
Q1: Why should I upgrade to an SSD for Windows 10 instead of a traditional HDD?
A1: An SSD dramatically improves your Windows 10 experience by offering faster boot times, quicker application loading, smoother multitasking, and faster file transfers. They’re also more durable, produce less heat, and are silent compared to traditional HDDs which have spinning platters and read/write heads.
Q2: Is a 500GB SSD enough for Windows 10?
A2: For most users, a 500GB (or 512GB) SSD is an excellent balance of capacity and performance for Windows 10. It provides ample space for the operating system, essential software, several large games, and a good amount of personal files. If you’re a heavy gamer or store a lot of large media files, you might consider a 1TB SSD or use a secondary HDD for bulk storage.
Q3: What’s the difference between SATA and NVMe SSDs, and which is better for Windows 10?
A3: SATA SSDs connect via the SATA III interface and offer speeds up to around 550MB/s. NVMe (Non-Volatile Memory Express) SSDs connect via the PCIe interface and are significantly faster, with modern Gen4 drives reaching speeds of 7000MB/s or more. For general everyday use on Windows 10, a SATA SSD provides a massive improvement over an HDD. For hardcore gamers, content creators, or those demanding the absolute best performance, an NVMe SSD (especially PCIe Gen4) is superior, provided your motherboard supports it.
Q4: Can I install a Lexar SSD in my existing laptop or desktop?
A4: Yes, for 2.5-inch SATA SSDs like the Lexar NS100 series, if your laptop or desktop currently uses a 2.5-inch hard drive, you can almost certainly swap it out for the SSD. For M.2 NVMe SSDs like the Lexar NM790, your system needs to have an available M.2 slot that supports NVMe. Always check your PC’s manual or manufacturer’s specifications for compatibility before purchasing.
Q5: What does “TBW” mean for an SSD?
A5: TBW stands for “Terabytes Written,” and it’s an endurance rating for SSDs. It indicates the total amount of data that can be written to the drive over its lifetime before it’s expected to fail. For example, a 240TBW drive means you can write 240 terabytes of data to it. For typical home users, SSDs usually last far longer than their TBW rating suggests, making it a less critical concern unless you’re performing extremely heavy write operations daily.
Q6: Are Lexar SSDs reliable for Windows 10?
A6: Yes, Lexar is a well-established brand in the memory and storage industry, known for producing reliable and cost-effective SSDs. Their drives often come with good warranties (like the 3-year limited warranty for the NS100 series and 5-year for the NM790), indicating confidence in their product’s longevity and performance.
Q7: Should I get an internal or external 500GB SSD for my Windows 10 machine?
A7: For installing Windows 10 itself and vastly improving your system’s speed, an internal SSD (like the Lexar NS100 or NM790) is what you need. An external 500GB SSD (like the Buffalo option reviewed) is excellent for portable storage, backups, expanding game libraries (especially for consoles), or running applications from the drive, but it’s generally not used as the primary boot drive for your OS.
