This article covers Samsung 990 PRO 1TB PCIe Gen 4.0 x4 (最大転送速度 7,450MB/秒) NVMe M.2 (2280) 内蔵 SSD MZ-V9P1T0B-IT.

Overview

The Samsung 990 PRO 1TB is an internal NVMe SSD that uses the M.2 2280 form factor and connects via PCIe Gen 4.0 x4. Its model number is MZ-V9P1T0B-IT, and it is sold as a domestic authorized product in Japan. The maximum sequential read speed is 7,450 MB/s, while write speed reaches 6,900 MB/s. Random performance is rated at 1,200,000 IOPS read and 1,550,000 IOPS write, placing it among the top-tier PCIe 4.0 drives.
This drive is designed for gaming PCs and creative workstations, aiming to accelerate OS boot times, application launches, and large file transfers. It sits in the mid-to-high-end segment of the PCIe 4.0 SSD market, offering a strong balance of performance and reliability for enthusiasts who want to maximize their system's storage speed.
The interface is NVMe 2.0 (PCIe Gen 4.0 x4), and the M.2 Type 2280 size means it fits into standard M.2 slots found on most modern motherboards. The 1TB capacity provides enough room for the operating system, key applications, and several games, making it a versatile choice for a primary drive.

Compatibility Guide

This SSD uses the M.2 2280 form factor, so you need a motherboard with an M.2 slot that supports PCIe Gen 4.0 x4 to achieve full speed. If you install it in a PCIe Gen 3.0 x4 slot, the transfer speed will be limited to the PCIe 3.0 bandwidth, which is roughly 3,500 MB/s. Check your motherboard's M.2 slot specifications before purchasing.
Compatible motherboards include those with Intel 600-series or newer chipsets, and AMD 500-series or newer chipsets. However, the number of M.2 slots and PCIe lane allocation varies by model, so it's wise to verify the manual. If your motherboard includes an M.2 heatsink, using it will help manage the drive's heat output.
The drive supports the NVMe 2.0 specification, but it should work in slots that support NVMe 1.3 or later. On older motherboards, a BIOS update might be required for full compatibility. Installation is straightforward: insert the drive into the M.2 slot and secure it with the screw provided by the motherboard.

Product Info

The Samsung 990 PRO 1TB was released in December 2022. Its price point places it in the mid-to-high range for 1TB PCIe 4.0 SSDs, appealing to users who prioritize performance and reliability. It is widely available through online retailers like the domestic authorized version includes a 5-year warranty or 600 TBW, whichever comes first.
Key performance figures include sequential read speeds of up to 7,450 MB/s and write speeds of up to 6,900 MB/s. Random performance is rated at 1,200,000 IOPS read and 1,550,000 IOPS write. The interface is NVMe 2.0 (PCIe Gen 4.0 x4), and the form factor is M.2 Type 2280.
In the market, this drive is positioned as a high-end PCIe 4.0 model, offering near-top-tier speeds within its generation. While PCIe 5.0 SSDs are emerging, the 990 PRO remains a strong choice for users with current motherboards, balancing performance, compatibility, and price.

Best Use Cases

  • Gamers who want to speed up their system drive: the 7,450 MB/s read speed reduces game load times and OS boot times. However, you need a PCIe 4.0 motherboard to take full advantage; otherwise, the drive will be bottlenecked by PCIe 3.0.
  • Creative professionals who handle large files, such as video editors or 3D artists: the high write speed and random performance help with loading assets and exporting projects. If 1TB is not enough for your library, consider a larger capacity model.
  • Users who value reliability and want a domestic authorized product: the 5-year warranty and 600 TBW endurance provide peace of mind for long-term use. Be aware that the warranty only applies to authorized domestic units, so avoid parallel imports.

Things to Consider

This SSD is designed for PCIe 4.0 x4, and using it in a PCIe 3.0 slot will cap speeds at around 3,500 MB/s, so you won't get the full performance. Also, some motherboards share PCIe lanes between M.2 slots and other devices, which could affect performance; check your motherboard manual for lane allocation.
Compared to other 1TB PCIe 4.0 SSDs, the 990 PRO is priced at a premium. If you're on a tight budget, a more affordable drive might meet your needs, though you may sacrifice some peak performance. The 1TB capacity is adequate for most users, but if you store large media libraries, a 2TB or larger model would be more practical.
Heat is another consideration: high-speed NVMe drives generate more heat, so using a motherboard M.2 heatsink is recommended. If your motherboard lacks one, consider aftermarket cooling solutions to maintain consistent performance.

FAQ

Q: Can I use this SSD on a PCIe 3.0 motherboard?
A: Yes, it will physically fit and work, but the transfer speed will be limited to PCIe 3.0 bandwidth (around 3,500 MB/s). To get the full 7,450 MB/s read speed, you need a PCIe 4.0-capable motherboard.
