This guide explains everything in simple words. Clear details. Real differences. Easy to understand.
SK hynix Gold P31
Product Details
Capacity, Form Factor, and Interface
SK hynix Gold P31 comes with 1TB storage capacity. This size fits most users. It stores games, software, videos, and work files without stress. The drive uses the M.2 2280 form factor.
Most modern laptops and desktops support this size. The interface uses PCIe NVMe 3.0. That means the drive works best on Gen3 motherboards, though it can also run on Gen4 slots at Gen3 speed.
The compact design helps in thin laptops. No cables needed. Just slide into the slot and secure with one screw. Simple and clean installation.
Speed Performance
The Gold P31 delivers up to 3,500 MB/s read speed and up to 3,200 MB/s write speed. These numbers sit near the top of PCIe Gen3 performance. Boot times feel fast. Programs open quickly. File transfers finish in seconds instead of minutes.
SK hynix uses HYPERWRITE cache technology. This feature boosts write speed during large transfers. The system writes data to a fast cache area first. Then it moves data to main storage. This process keeps performance stable during heavy workloads.
Reliability and Endurance
The Gold P31 includes a 5-year warranty. Endurance reaches up to 1,200 TBW. That means users can write up to 1,200 terabytes of data before reaching the rated limit. MTBF reaches 1.5 million hours. SK hynix also tested the drive with 1,000 hours of HTOL stress testing. These numbers show strong long-term durability.
Laptop users benefit from its thermal efficiency. The drive runs cool under load. Lower temperature improves lifespan and keeps speed steady.
Features
Excellent Power Efficiency
Gold P31 uses less power than many Gen3 SSDs. Laptops gain longer battery life. Less heat builds inside small systems. The drive stays efficient even under heavy use.
Strong Thermal Control
The controller and NAND design help reduce heat. Many users report stable temperatures even without a heatsink. This matters in thin laptops where airflow stays limited.
Easy Migration Software
SK hynix provides Macrium cloning software. Users can copy the old drive to the new SSD easily. No need to reinstall Windows or programs from scratch.
Broad Device Support
The drive supports desktops and laptops with M.2 NVMe slots. It does not support Sony PS5. Buyers must confirm motherboard compatibility before purchase.
What Is the Good?
Gold P31 offers near maximum Gen3 speed. It runs cool and efficient. It provides high endurance rating. It delivers stable performance during long tasks. Laptop users enjoy strong battery efficiency. Price often stays lower than high-end Gen4 drives.
The drive balances speed, power use, and reliability very well.
What Is the Bad?
The drive cannot reach Gen4 speeds. High-end users may want faster numbers. It does not include a heatsink in the box. It does not support PS5. Heavy video editors who need extreme speed may prefer Gen4 models.
Overall Opinion
SK hynix Gold P31 fits users who want reliable Gen3 performance without high cost. Office users, students, and moderate gamers benefit most. Laptop owners gain extra battery efficiency and lower heat. It may not break speed records, but it delivers consistent daily performance with strong durability.
Samsung 990 PRO
Product Details
Capacity, Interface, and Build
Samsung 990 PRO also offers 1TB storage. It uses M.2 2280 form factor like the Gold P31. The big difference appears in the interface. Samsung uses PCIe 4.0 NVMe. This allows much higher data transfer speed compared to PCIe 3.0.
The slim design fits most desktops and laptops that support PCIe 4.0. PS5 systems also support this drive with proper installation and heatsink if required.
Speed Performance
Samsung 990 PRO reaches up to 7,450 MB/s read speed and up to 6,900 MB/s write speed. These numbers nearly double Gen3 performance. Large games load very fast. 4K video editing feels smoother. Heavy file transfers complete in very short time.
Random performance also improves strongly. The drive reaches up to 1,400K read IOPS and 1,550K write IOPS. That means better performance in multitasking. Systems feel very responsive.
Thermal and Power Design
Samsung uses a nickel-coated controller for thermal control. The design helps manage heat during high-speed tasks. Performance per watt improves compared to older Samsung models. The drive delivers strong speed while managing power use effectively.
Samsung also includes Magician software. Users can monitor drive health, update firmware, and optimize performance.
Features
PCIe 4.0 High-Speed Performance
The biggest feature remains Gen4 speed. Modern motherboards with PCIe 4.0 slots allow full performance. Heavy users notice faster game loads and quicker rendering times.
Strong Gaming Support
Fast random speeds improve DirectStorage game loading. PS5 users also benefit from high read speed for large games.
Hardware Encryption
Samsung includes 256-bit AES hardware encryption. Sensitive data stays protected. Business users value this feature.
Advanced Software Support
Samsung Magician software provides health monitoring, performance optimization, and firmware updates. This adds long-term support.
What Is the Good?
Very high read and write speeds. Excellent random performance. Strong gaming results. Advanced thermal control. Encryption support. Works with PS5 and modern Gen4 systems.
Power users gain clear performance improvement over Gen3 drives.
What Is the Bad?
Price stays higher than Gen3 SSDs. Systems without PCIe 4.0 cannot use full speed. High performance can create more heat in small cases without airflow. Casual users may not notice full speed benefit.
Overall Opinion
Samsung 990 PRO targets gamers, creators, and heavy multitaskers. It shines in demanding tasks like video editing, large game installs, and high-speed file transfers. Budget users may not need this level of performance. Enthusiasts and professionals often prefer this drive for its raw speed and advanced features.
Details Comparison
Gold P31 and Samsung 990 PRO serve different markets. Gold P31 runs on PCIe 3.0 with 3,500 MB/s read speed. Samsung 990 PRO runs on PCIe 4.0 with 7,450 MB/s read speed. That creates a major difference in raw numbers.
Real-world difference depends on usage. Office work, web browsing, and basic gaming show small differences. Heavy video editing, 4K file transfers, and large game installations show clear improvement on the Samsung drive.
Thermal performance favors Gold P31 in small laptops. It runs cooler and uses less power. Samsung 990 PRO focuses on peak speed. Good airflow helps maintain stable performance.
