FAQ: All Your Lexar M.2 SSD Gaming Questions Answered
Q1: What’s the difference between PCIe Gen4 and PCIe Gen5 SSDs?
A1: PCIe Gen5 is the latest generation of the PCIe interface, offering double the theoretical bandwidth of PCIe Gen4. This translates to significantly faster sequential read/write speeds (e.g., 14,000 MB/s for Gen5 vs. 7,400 MB/s for Gen4). While Gen5 offers cutting-edge performance, Gen4 is still incredibly fast and more than sufficient for most current gaming needs. Gen5 requires a compatible motherboard (e.g., Z790 for Intel, X670 for AMD).
Q2: Do I really need a Gen5 SSD for gaming right now?
A2: For most current games, a high-end PCIe Gen4 SSD (like the Lexar NM790 series) is more than enough. The performance gains from Gen5 SSDs are most noticeable in specific workloads like large file transfers, AI tasks, or future games heavily utilizing Microsoft DirectStorage. If you’re building a top-tier PC and want to future-proof for years to come, Gen5 is a solid investment. Otherwise, Gen4 offers a better bang-for-your-buck for pure gaming.
Q3: What is DirectStorage, and why is it important for gaming SSDs?
A3: DirectStorage is a Windows API that allows games to load assets directly from an NVMe SSD to the GPU, bypassing the CPU. This significantly reduces CPU overhead, speeds up game loading, and enables richer, more detailed game worlds. For games to fully leverage DirectStorage, they need ultra-fast NVMe SSDs, with PCIe Gen4 and especially Gen5 drives being ideal.
Q4: Do I need a heatsink for my M.2 SSD?
A4: For high-performance NVMe SSDs, especially PCIe Gen4 and Gen5 drives, a heatsink is highly recommended. These drives can generate considerable heat under sustained load, which can lead to thermal throttling and reduced performance. Many motherboards come with integrated M.2 heatsinks, or you can opt for an SSD with a pre-attached heatsink like the Lexar NM790 with heatsink.
Q5: How easy is it to install an M.2 SSD?
A5: Installing an M.2 SSD is relatively straightforward. Most motherboards have one or more M.2 slots. You simply insert the SSD into the slot at an angle, push it down, and secure it with a small screw or clip provided by your motherboard. For laptops, it might require opening the case and locating the M.2 slot, but the process is similar.
Q6: What does “TBW” mean, and why is it important?
A6: 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 over its lifespan before it’s expected to fail. Higher TBW values mean greater durability. For gaming, even a moderately sized TBW (e.g., 1000 TBW for a 1TB drive) is usually more than enough for many years of heavy use.
Q7: Can I use these Lexar M.2 SSDs in my PlayStation 5?
A7: Yes, the Lexar NM790 series (both with and without heatsink) is fully compatible with the PlayStation 5, provided you choose a 1TB or 2TB model with a read speed of 5500MB/s or higher (which all NM790 models exceed). Make sure to check the PS5’s specific requirements for heatsink dimensions if you’re adding one yourself. The NM1090 PRO Gen5 drives are also compatible, offering even more headroom.
Final Thoughts on Lexar Best M.2 SSD for Gaming
Choosing the Lexar best M.2 SSD for gaming depends on your specific needs, existing hardware, and budget. If you’re building a top-of-the-line, future-proof PC, the Lexar NM1090 PRO PCIe Gen5 drives offer unparalleled speed. However, for the majority of gamers, the Lexar NM790 PCIe Gen4 series provides an incredible balance of blistering performance, reliability, and value, especially the version with the integrated heatsink or the flexible single-sided models for laptops and PS5.
No matter which Lexar M.2 SSD you choose, you’re in for a significant upgrade that will drastically improve your gaming experience. Say goodbye to long loading screens and hello to seamless, high-speed action!
