Frequently Asked Questions (FAQ)
Q1: What’s the main difference between an internal and an external SSD for my XPS 15?
A1: An internal SSD (like the NM790 or NM1090 PRO) replaces or adds to the storage inside your laptop, serving as your primary drive or a secondary fast storage. It offers the fastest possible speeds for booting your OS and running applications. An external SSD (like the Go Portable, ES3, ES5, or SL500) connects via a USB port and is used for portable storage, backups, or expanding capacity without opening your laptop.
Q2: Can I install an NVMe SSD in my XPS 15 myself?
A2: Yes, generally. Dell XPS 15 laptops usually have an accessible M.2 slot for NVMe SSDs. However, it requires some technical comfort with opening your laptop, handling small components, and potentially reinstalling your operating system if you’re replacing the boot drive. Always refer to your specific XPS 15 model’s service manual or a reliable tutorial for detailed instructions.
Q3: Which Lexar SSD speed is best for video editing on an XPS 15?
A3: For video editing, higher read and write speeds are crucial.
* Internal: The Lexar 1TB NM790 (PCIe Gen4) or NM1090 PRO (PCIe Gen5) will offer the best internal performance for working with large video files directly on your system.
* External: The Lexar 1TB ES5 Magnetic External SSD or SL500 Portable SSD (both USB 3.2 Gen 2×2) provide exceptional external speeds for storing and editing projects directly off the drive. The Professional Go Portable SSDs are also great, supporting Apple ProRes recording.
Q4: Will a PCIe Gen5 SSD work in an XPS 15 that only supports Gen3 or Gen4?
A4: Yes, a PCIe Gen5 SSD like the Lexar NM1090 PRO is backward compatible and will work in a Gen3 or Gen4 M.2 slot. However, it will only operate at the maximum speed supported by that slot (e.g., Gen4 speeds if in a Gen4 slot, or Gen3 speeds if in a Gen3 slot). You won’t get the full Gen5 performance, but it will still be incredibly fast.
Q5: What is Lexar DataShield?
A5: Lexar DataShield is 256-bit AES encryption software included with some Lexar external SSDs (like the ES3 and SL500). It helps protect your sensitive files by encrypting them, requiring a password to access the data. This adds an extra layer of security, especially important for portable drives.
Q6: How do I know which M.2 slot my XPS 15 has (e.g., PCIe Gen3 or Gen4)?
A6: The PCIe generation supported by your XPS 15’s M.2 slot depends on your laptop’s specific model year and CPU generation.
* 10th Gen Intel CPUs and older: Typically support PCIe Gen3.
* 11th Gen Intel CPUs and newer: Often support PCIe Gen4.
To be absolutely sure, check your XPS 15’s exact model number (e.g., XPS 15 9510, 9520, 9530) and consult Dell’s official specifications or your laptop’s service manual. You can also use system information tools or SSD utility software to identify your M.2 slot’s capabilities.
Q7: Are Lexar SSDs reliable for daily use and demanding tasks?
A7: Absolutely. Lexar is a well-established brand in memory and storage, known for producing reliable and high-performance products. Their SSDs undergo rigorous testing, and many come with competitive warranties (like the five-year limited warranty on several products listed). For daily use and demanding tasks like content creation or gaming, Lexar SSDs are a trustworthy choice.
