Lenovo E490 Core i3 8th Gen: M.2 Slot SSD Choices

When upgrading the storage in your Lenovo E490 Core i3 8th Gen, one of the critical decisions you'll face is selecting the appropriate type of SSD for the M.2 slot. The key specifications to consider are the size of the M.2 SSD (2280 or 2242) and its interface (SATA or NVMe 3.0).

Understanding M.2 SSD Specifications

The M.2 slot on your Lenovo E490 can accommodate different types of SSDs. The 2242 slots are older and typically use NVMe 3.0 x2, while the 2280 slots can support either SATA or the newer NVMe 3.0 x4 configurations. Understanding the specific type of M.2 slot you have will help you narrow down your options.

Choosing the Right SSD

Once you've identified the correct M.2 slot, you'll need to prioritize your storage needs and budget. Here are the key considerations:

Storage Capacity

The standard M.2 SSD that came with your Lenovo E490 has a relatively small 512GB capacity. If you require more storage, you can upgrade to a larger capacity SSD. However, the actual slots available will depend on your system's configuration. For instance, the E490 typically comes with a 2280 M.2 slot, which can accommodate a wider range of SSD capacities.

Budget and Performance

Your budget will play a significant role in determining the type of SSD you can afford. If you only need moderate performance, a SATA SSD is a viable option. However, if you prioritize performance, NVMe SSDs are highly recommended. It's important to note that while NVMe 4.0 drives may be the latest technology, they are not necessary for the E490 since it only provides NVMe 3.0 performance. Therefore, investing in an NVMe 3.0 drive is sufficient.

SSD Type: TLC vs QLC

When it comes to selecting the right NAND type, Adaptive tech users often choose between TLC (Triple-Level Cell) and QLC (Quad-Level Cell). While QLC offers higher storage density and lower costs, TLC is generally preferred for its faster read and write speeds.

Do Not:
Despite the availability, QLC SSDs are not recommended for budget-conscious users at this time. QLC SSDs can be prone to wear and frequent write cycles, which can impact their longevity and reliability.

Recommendations:
Select a TLC-based NVMe SSD for the best balance of performance and longevity. Examples include the Kingston A2000 or the Crucial P1. Both offer NVMe 3.0 performance and durable TLC NAND.

Conclusion

By carefully considering your storage needs and budget, you can ensure that your upgrade to a higher-performance SSD enhances the overall performance of your Lenovo E490 Core i3 8th Gen. Remember to choose the appropriate M.2 slot type and stick with TLC-based SSDs for optimal performance and reliability.

Frequently Asked Questions

Q: Can I upgrade the M.2 slot to a different type?
A: The E490 typically supports 2280 and 2242 M.2 slots. The specific slot you have determines the type of SSD you can use. Ensure you match the specifications of your existing slot to avoid compatibility issues.

Q: How much storage should I choose?
