Frequently Asked Questions (FAQ)
Q1: What’s the main difference between SATA and NVMe SSDs?
A1: The main difference lies in their interface and speed. SATA SSDs connect via the SATA port, offering speeds typically up to 550MB/s. NVMe (Non-Volatile Memory Express) SSDs connect via the PCIe interface, which is much faster, often reaching speeds of 3000MB/s to 7000MB/s or more, as seen in the Lexar NM790 series. NVMe drives are generally preferred for modern PCs, gaming, and demanding applications.
Q2: Will a Lexar SSD really make my old PC faster?
A2: Absolutely! If your old PC is still using a traditional hard disk drive (HDD), upgrading to even a SATA SSD like the Lexar NS100 will provide a dramatic improvement. You’ll notice much faster boot times, quicker application launches, and an overall snappier system response. It’s one of the most cost-effective upgrades for older machines.
Q3: Do I need a heatsink for my NVMe SSD?
A3: For most casual use, an NVMe SSD might not strictly need a heatsink. However, for sustained heavy workloads like intense gaming, video editing, or large file transfers, NVMe drives can generate significant heat. A heatsink, like the one included with the Lexar 2TB NM790, helps dissipate this heat, preventing thermal throttling and ensuring the drive maintains its peak performance. For laptops or well-ventilated desktops, it might be less critical, but it’s always a good idea for high-performance usage.
Q4: Can I use an external Lexar SSD for gaming?
A4: Yes, you can! External SSDs like the Lexar ES3 series, with their high USB 3.2 Gen 2 speeds, are excellent for storing and running games, especially for consoles like the PS5 (for PS4 games or as extended storage) or Xbox. For PC gaming, while an internal NVMe SSD will offer the best performance, a fast external SSD can still provide a much better experience than running games from a traditional external HDD.
Q5: How do I install an internal Lexar SSD in my PC?
A5: Installing an internal SSD usually involves a few steps:
1. Backup: Always back up your data first!
2. Mounting: For 2.5-inch SATA SSDs, you’ll mount it in a drive bay and connect SATA data and power cables.
3. M.2 NVMe: For M.2 drives, you’ll insert it into the M.2 slot on your motherboard and secure it with a screw.
4. OS Migration/Installation: You can either clone your existing operating system to the new SSD or perform a fresh installation.
Many tutorials are available online, and Lexar often provides guides with their products.
Q6: What does TBW mean for SSDs?
A6: TBW stands for “Terabytes Written,” and it’s a measure of an SSD’s endurance – how much data can be written to the drive over its lifetime before its reliability might degrade. For example, a 1000TBW rating means the drive can theoretically have 1000 terabytes of data written to it. Higher TBW values indicate greater durability, which is important for power users or those who frequently write large amounts of data. Lexar’s SSDs generally offer very competitive TBW ratings.
