This article covers SAMSUNG 990 SSD 2TB PCIe Gen4 NVMe M.2 内蔵ソリッドステートハードドライブ 最大7.

Overview

Samsung's latest mid-range NVMe SSD, the SAMSUNG 990 SSD 2TB (model MZ-V9V2T0B/AM), is here to offer a compelling balance of speed and efficiency. It leverages a PCIe Gen4 x4 interface to deliver sequential read speeds up to 7,250 MB/s and write speeds up to 6,450 MB/s, with random read/write at 850K/1,200K IOPS. Compared to the 990 PRO, it achieves up to 38% better performance per watt, making it ideal for thermally constrained systems like laptops. Priced around ¥60,000 on Japan at launch, it's a strong value proposition for gamers and creators who need fast storage without breaking the bank.

Compatibility Guide

Form factor: M.2 2280 (22x80mm) fits both desktops and laptops with an M.2 NVMe slot. No 2.5-inch or mSATA compatibility. Interface: PCIe Gen4 x4 NVMe 1.4c. Backward compatible with PCIe Gen3, but speeds will drop to ~3,500 MB/s sequential. No additional power cables required; powered directly from the M.2 slot. Works with all modern motherboards supporting NVMe; no special chipset requirements.

Product Info

Released in 2024 as a Canadian import model, this SSD is available through Japan. It carries a 5-year manufacturer warranty (subject to Samsung registration, but note that import models may not be covered in Japan). Market positioning: mid-range Gen4 drive with near-flagship sequential speeds and lower power draw. The controller is optimized for efficiency, reducing heat output compared to the 990 PRO. It uses Samsung's 7th-generation V-NAND (likely 3D TLC NAND) and the new Pascal controller (DRAM-less design, but with Samsung's HMB technology).

Best Use Cases

Gamers: DirectStorage-ready, large game libraries load quickly. 2TB holds multiple AAA titles. Random performance is adequate for smooth texture streaming. Not ideal for extreme overclocking or heavy multi-threaded workloads where 990 PRO's random IOPS matter. Content Creators: Excellent for 4K video editing, large photo libraries, and fast export of project files. Sequential writes are strong. However, sustained write performance may drop after large multi-GB transfers (DRAM-less behavior). Consider a DRAM-equipped drive if you do constant heavy writes. * Power-conscious users: Laptop owners and small-form-factor PC builders will appreciate the lower power consumption and heat. Great for thin notebooks where a 990 PRO might throttle.

Things to Consider

This is a Canadian import, so Japanese warranty support may not be available. Check seller policies before buying. Compared to competitors like WD SN850X (with DRAM) or Crucial T500, the 990 SSD offers slightly lower random reads but better efficiency and often lower price. If you do heavy server-style workloads, consider a DRAM drive. In a PCIe Gen3 system, the speed advantage is lost; a cheaper Gen3 drive makes more sense. The controller is DRAM-less but uses HMB (Host Memory Buffer) to borrow system RAM, which works well for most users. However, on systems with limited RAM or in multi-tasking scenarios, performance may be less consistent. ## FAQ
Q: Can I use this in a PS5? A: Yes, it meets the PS5's speed requirement (7,250 MB/s > 5,500 MB/s required). You'll need to attach a heatsink (not included). Q: How does it compare to the 990 PRO? A: The 990 PRO has higher random IOPS (1,400K read) and a DRAM cache, making it better for heavy multitasking and server use. The 990 SSD offers better efficiency and lower cost for gaming and daily use. Q: Does it support S.M.A.R.T. and TRIM? A: Yes, standard NVMe features including S.M.A.R.T. monitoring and TRIM are supported. Samsung Magician software can be used for firmware updates and health checks.
