This article covers Samsung SSD 4TB 990 PRO PCIE X4 ソリッドステートディスク NVMe GB。.

Overview

Samsung's flagship NVMe SSD, the 990 PRO series, now comes in a massive 4TB capacity variant (model MZ-V9P4T0GW). This drive leverages the PCIe 4.0 x4 interface to deliver sequential read speeds up to 7450 MB/s and write speeds up to 6900 MB/s, placing it at the top of the consumer SSD performance chart. Despite its enormous storage capacity, it retains the compact M.2 2280 form factor, making it an ideal drop-in upgrade for both desktops and high-end laptops with an M.2 slot. This SSD is designed for demanding users who need both speed and capacity without compromise.

Compatibility Guide

The 990 PRO 4TB uses the M.2 2280 form factor and supports the NVMe 2.0 protocol over a PCIe 4.0 x4 interface. It is backward compatible with PCIe 3.0 slots, though speeds will be limited to the PCIe 3.0 ceiling. Virtually any motherboard with an M.2 slot can accommodate this drive physically. For sustained heavy workloads, we recommend using the motherboard's built-in M.2 heatsink or an aftermarket cooler to maintain optimal temperatures, as the 4TB capacity can generate significant heat under continuous write operations.

Product Info

Released in 2024, the Samsung 990 PRO 4TB sits at the high end of the consumer NVMe market. Pricing is around 140,000 JPY, which is typical for a 4TB PCIe 4.0 SSD with these performance specs. Samsung backs the drive with a 5-year limited warranty or 2400 TBW (whichever comes first), offering solid long-term reliability. It is available through major retailers such as . View on

Best Use Cases

Gamers: With massive game installations becoming the norm, this SSD slashes load times and accelerates texture streaming in DirectStorage titles. Perfect for a high-end gaming rig. Content Creators: Video editors working with 4K/8K footage, photographers handling huge RAW files, and 3D artists will appreciate the sustained high throughput for large file transfers. * Enthusiast Builders: For those building a no-compromise system where every component must be top-tier, the 990 PRO 4TB is the current sweet spot in price vs. PCIe 4.0 performance. It avoids the premium of PCIe 5.0 while still offering near-maximum speed.

Things to Consider

The 990 PRO does not support PCIe 5.0, so if you are building a future-proof system with the latest platform, a Gen5 SSD might be a better long-term fit. For everyday tasks like browsing and office work, the performance advantage over a more affordable Gen3 drive is negligible, making this SSD overkill for casual users. The 4TB model may experience some performance degradation when nearly full, and heavy write workloads require adequate cooling. Avoid installing it in laptops without proper heatsink and airflow. Compared to competitors like the WD Black SN850X 4TB, both offer similar speeds, but Samsung's software (Samsung Magician) provides excellent management and firmware update tools.
