Best SSDs for Upgrading or Replacing Your Drive (2025 Buyer’s Guide)

The storage performance of your computer can truly make a difference in your overall computing experience, like a lot! If you’re currently using a traditional hard drive (HDD), you’re probably powering on your PC and then going for a walk just so you can give it enough time to start up properly.

Upgrading to a solid-state drive (SSD) can change that and significantly boost your performance—from blazing-fast boot times to lightning-quick file access. Having your operating system installed on a traditional hard drive in 2025 is a big no-no in my book, you definitely need to replace it with a solid state drive (SSD).

That’s why I’ll walk you through some of the best SSD options available in 2025 to help you make a smart decision for upgrading or replacing your drive.

Top SSD Picks (Shortlist)

Here are my top picks for solid state drives you should consider when buying a new SSD.

Understanding SSDs: What You Need to Know

What is an SSD?

A solid-state drive (SSD) is a storage device that uses NAND-based flash memory to hold your data. Unlike traditional HDDs, which have spinning disks and moving parts, SSDs are all about speed. They can access data almost instantly, making them an essential upgrade for gamers, content creators, and anyone wanting a smoother computing experience, even the every-day computer user.

The Evolution of SSD Technology

Over the past decade, SSD technology has come a long way. Initially viewed as a luxury, prices have dropped, and performance has soared. The introduction of NVMe (Non-Volatile Memory Express) tech has taken speed to the next level, utilizing the PCIe (Peripheral Component Interconnect Express) interface. As of 2025, Gen 4 and even Gen 5 NVMe SSDs are now common, making it an exciting time for newcomers and tech enthusiasts alike.

Why Opt for an SSD?

• Speed: Say goodbye to long boot times and hello to applications that load in the blink of an eye.
• Durability: SSDs have no moving parts, meaning they can withstand shocks and wear better than HDDs.
• Silent Operation: Enjoy quieter computing environments—great for laptops and workspaces.
• Energy Efficiency: SSDs use less power, extending battery life for portable devices.

Types of SSDs to Consider

Internal SSDs

SATA SSDs

• Interface: SATA (Serial Advanced Technology Attachment) – The same tradition hard drives uses.
• Speed: Tops out at around 600 MB/s.
• Ideal For: Older systems lacking NVMe support, or if you’re on a budget.
• Examples: Crucial MX500, Samsung 870 EVO.

NVMe SSDs

• Interface: PCIe (Peripheral Component Interconnect Express)
• Speed: Can reach speeds of over 7,000 MB/s.
• Ideal For: Gaming, video editing, and any demanding applications.
• Examples: WD Black SN850X, Samsung 990 Pro, Crucial T705.

External SSDs

External SSDs provide the same technology in portable formats. They usually connect via USB or Thunderbolt, making them perfect for users needing extra storage on the go.

Key Features to Look For

• Bus Speed: Look for support for faster transfer speeds, like USB 3.2 or Thunderbolt 3.
• Durability: Choose rugged designs if you’re on the move often.

Important Performance Factors

DRAM vs. HMB

• DRAM: Provides quicker data access, beneficial for multitasking.
• HMB: Utilizes part of your computer’s memory, offering a decent performance for everyday tasks at a lower cost.

NAND Types

• TLC (Triple-Level Cell): Balances speed and price, great for general use.
• QLC (Quad-Level Cell): More affordable and high capacity, though it can lag in performance over time.

PCIe Generations

SSDs are categorized by PCIe versions (Gen3, Gen4, Gen5). Make sure your motherboard is compatible to avoid performance issues.

Capacity Considerations

SSDs come in sizes ranging from 250GB to 8TB. Higher capacities often translate to better performance, especially with large files. Generally, for gaming, aim for at least 1TB, and 2TB if you have a large library—some games can exceed 200GB!

Pricing and Recommended Brands

Choosing an SSD means balancing performance and price. I’ve found that some brands consistently produce reliable options:

• Samsung: Top-notch internal SSDs, particularly in the NVMe space.
• Western Digital (WD): Great offerings for both gamers and general users.
• Crucial: Budget-friendly without skimping on quality.

What to Look for in Warranty and TBW Ratings

Most SSDs offer warranties of 3 to 5 years. TBW (Terabytes Written) ratings indicate durability—higher numbers suggest longer lifespans, which is vital for heavy users.

BIOS Compatibility

Before you buy an NVMe drive, ensure your system can boot from it. Some older systems might require updates, or may not support NVMe drives at all.
