SSD 2026 Value Tier - Gen4 vs Gen5 Perceived Performance Comparison: Expert Analysis

In recent years, SSD (Solid State Drive) technology has made remarkable progress. In particular, with the advent of PCIe 5.0 (Gen5) SSDs beyond PCIe 4.0 (Gen4), data access speeds have increased beyond imagination. However, not all users need the latest technology. This blog post classifies the main SSDs currently on the market as tier levels based on performance, durability, and price, and carefully compares and analyzes the actual perceived performance differences between Gen4 and Gen5 SSDs to help you make a rational SSD selection.

1. SSD Tier Ratings (as of 2026)

Below is the result of classifying the main SSD models currently available on the market into tiers from S to C, considering speed, durability, and price thoroughly. Prices are based on a 2TB model and are subject to change.

S Tier (Best Choice): Overwhelming Performance and Price-Performance Ratio

• Samsung 990 PRO: Provides top-level sequential read/write speeds (up to 7,450MB/s read, 6,900MB/s write) and is optimized for high-performance tasks such as reducing game loading times and high-resolution video editing. Despite recent price fluctuations, it still has excellent performance.
• WD Black SN850X: Shows outstanding performance comparable to the Samsung 990 PRO and offers features specialized for gaming environments.

A Tier (Very Excellent Choice): High Performance and Stable Durability

• important T500: A product that simultaneously offers excellent performance and a reasonable price. While there is a slight performance difference compared to the 990 PRO, it provides sufficient performance for most users.
• SK Hynix Platinum P41: Receives good reviews from users for its fast speed and stable performance.

B Tier (Good Choice): Decent Performance and Cost-Effectiveness

• important P5 Plus: Offers a balanced performance and price among Gen4 SSDs, suitable for everyday use and light gaming.
• Kingston KC3000: Reliable performance and decent price, can be used for various purposes.

C Tier (Entry-Level Choice): Choice for Budget Savings

• important P3: A product that allows you to experience SSDs at the lowest price. Suitable for light tasks such as document processing, web browsing, rather than video editing or high-spec gaming.

2. Gen4 vs Gen5 SSD: How Much of a Perceived Performance Difference Will There Be?

PCIe 5.0 SSDs theoretically offer twice the speed of PCIe 4.0 SSDs. Some Gen5 SSDs show sequential read speeds exceeding 14,000MB/s. However, will this massive speed difference be noticeably felt in actual use?

High-Performance Gaming: For users who enjoy high-performance games, Gen5 SSDs can help reduce loading times. However, with the increasing optimization levels of recent game engines, the loading time difference between Gen4 SSDs and Gen5 SSDs may be minimal. if bottlenecks occur due to other hardware performance such as graphics cards and CPUs, the effect of improved SSD performance will be further reduced.

Video Editing and 3D Rendering: Gen5 SSDs offer greater benefits to users who perform high-performance tasks such as video editing or 3D rendering. You can shorten work time by quickly reading and writing large files. When dealing with video files larger than 50GB, Gen5 SSDs show much faster transfer speeds than Gen4 SSDs like the 990 PRO.

General Use: In general use environments such as document processing, web browsing, and email, it is difficult to feel a perceived performance difference between Gen4 SSDs and Gen5 SSDs.

3. Price and Cost-Effectiveness: Which SSD Should You Choose?

Gen5 SSDs offer high performance, but their price is also very expensive. Currently, the price of a 2TB Gen5 SSD often exceeds 200,000 won. On the other hand, a 2TB Gen4 SSD can be purchased for 120,000 to 200,000 won. Therefore, it is important to make a rational choice considering your purpose and budget.

• Users who want the best performance: Gen5 SSD (Samsung 990 PRO, WD Black SN850X, etc.)
• Users who enjoy high-performance games and high-performance tasks: A Tier Gen4 SSD (important T500, SK Hynix Platinum P41)
• Users who want decent performance at a reasonable price: B Tier Gen4 SSD (important P5 Plus, Kingston KC3000)
• Users looking for budget savings: C Tier SSD (important P3)
