Choosing Your Lexar 1TB SSD: Internal vs. External
When looking for the Lexar best 1TB SSD for PC, it’s crucial to differentiate between internal and external options:
- Internal SSDs (NM790, NM790 w/ Heatsink, NM1090 PRO): These are installed directly inside your PC, typically in an M.2 slot. They offer the fastest possible speeds and are ideal for your operating system, games, and frequently accessed applications. They’re designed for maximum system performance and responsiveness.
- External SSDs (ES5 Magnetic, Professional Go Portable): These connect to your PC via a USB cable. They are fantastic for portable storage, backups, expanding storage without opening your PC, and working with large files across different devices. While fast, their speeds are generally limited by the USB interface and won’t match the raw throughput of internal NVMe drives.
Consider your primary use case: if you want to speed up your core system, go internal. If you need portable, flexible, and durable storage, an external drive is your friend.
FAQ: Everything You Need to Know About 1TB SSDs
Q1: What’s the difference between PCIe Gen4 and PCIe Gen5?
A1: PCIe Gen5 is the newer generation of the Peripheral Component Interconnect Express interface, offering significantly higher bandwidth and thus faster read/write speeds than PCIe Gen4. Gen5 can roughly double the theoretical maximum speeds of Gen4, but it requires a compatible motherboard and CPU.
Q2: Do I need a heatsink for my NVMe SSD?
A2: For high-performance NVMe SSDs, especially PCIe Gen4 and Gen5 drives, a heatsink is highly recommended. It helps dissipate heat generated during heavy use, preventing thermal throttling and ensuring the drive maintains its peak performance over extended periods. Many newer motherboards come with integrated M.2 heatsinks.
Q3: Is a 1TB SSD enough for gaming?
A3: For most gamers, a 1TB SSD is an excellent starting point. It’s enough to hold your operating system, several AAA titles, and essential applications. However, if you play many large modern games simultaneously, you might eventually need more space or supplement it with a secondary drive.
Q4: Can I install a Lexar NVMe SSD in any PC?
A4: Your PC needs an available M.2 slot on its motherboard to install an NVMe SSD. To fully utilize PCIe Gen4 or Gen5 speeds, your motherboard and CPU must also support that specific PCIe generation. Check your motherboard’s specifications before purchasing.
Q5: What does TBW (Terabytes Written) mean?
A5: TBW stands for Terabytes Written and is a measure of an SSD’s endurance. It indicates the total amount of data that can be written to the drive over its lifetime before its reliability might start to degrade. Higher TBW ratings mean a longer lifespan for the drive.
Q6: What are the benefits of an external SSD like the Lexar ES5 or Professional Go?
A6: External SSDs offer portability, allowing you to carry large files or projects between different computers. They’re excellent for backups, expanding storage without opening your PC, and providing fast access to media files for editing on the go. Their plug-and-play nature makes them very convenient.
Q7: Will upgrading to an SSD make my old PC faster?
A7: Yes, upgrading from a traditional hard drive (HDD) to an SSD is one of the most impactful upgrades you can make to an older PC. You’ll notice significantly faster boot times, quicker application loading, and overall snappier system responsiveness, even if other components are older.
Conclusion
Choosing the Lexar best 1TB SSD for PC really comes down to your specific needs and budget. For those building a bleeding-edge system or demanding the absolute fastest internal storage, the Lexar NM1090 PRO PCIe Gen5 is an unrivaled beast. If you’re looking for an excellent balance of speed, efficiency, and value in an internal drive, both versions of the Lexar NM790 PCIe Gen4 are stellar choices, with the heatsink model offering peace of mind for thermal management.
