This article covers Samsung 990 EVO Plus 2TB PCIe Gen 4.0 ×4 NVMe M.2 (2280) TLC NAND 最大 7,250MB/秒 内蔵 SSD MZ-V9S2T0B-IT.

## Overview
Samsung released the 990 EVO Plus 2TB in November 2024 as a mainstream NVMe SSD that bridges the gap between the flagship 990 PRO and the budget-oriented 980 series. The model number is MZ-V9S2T0B-IT/EC, and it comes with official domestic warranty coverage when purchased through authorized Japanese retailers. Sequential read speeds reach up to 7,250MB/s with write speeds up to 6,300MB/s, making this drive a solid choice for gaming PCs and creative workstations.
What sets this drive apart is its dual-interface design supporting both PCIe Gen 4.0 x4 and PCIe Gen 5.0 x2 connections. It complies with the NVMe 2.0 specification and uses TLC NAND flash memory. Random performance is rated at 1,000,000 IOPS for reads and 1,350,000 IOPS for writes, which keeps OS boot times and application loading snappy in everyday use.
In the current SSD market, the 990 EVO Plus sits in the mid-range tier, offering near-flagship sequential performance at a more accessible price point. The 2TB capacity provides ample room for game libraries, creative project files, and system backups without requiring an immediate upgrade.

## Compatibility Guide
This drive uses the M.2 Type 2280 form factor, which is the most common size found on modern desktop motherboards. It fits into any standard M.2 slot, whether your board supports PCIe 4.0 or PCIe 5.0. The dual-interface design means you can install it on a PCIe 4.0 system today and carry it over to a PCIe 5.0 platform later without losing compatibility.
Since the drive complies with NVMe 2.0, most recent motherboards will recognize it without additional driver installation. However, older platforms may require a BIOS update to properly detect and boot from the drive. Before purchasing, check your motherboard's M.2 slot configuration, as some boards share PCIe lanes with other components like SATA ports or additional M.2 slots.
For laptop users, the M.2 2280 form factor is also widely supported in modern notebooks. Installation requires opening the bottom cover, which may void the manufacturer's warranty on some models. Always consult your laptop's service manual before attempting an upgrade.

## Product Info
The Samsung 990 EVO Plus 2TB launched on November 13, 2024, making it a relatively recent addition to Samsung's SSD lineup. It occupies the mid-range segment, delivering sequential performance close to the flagship 990 PRO while keeping the price more accessible. The drive achieves up to 7,250MB/s sequential reads and 6,300MB/s sequential writes, with random performance rated at 1,000,000 IOPS read and 1,350,000 IOPS write.
The NAND flash is TLC based, utilizing Samsung's 236-layer V-NAND technology. The controller is Samsung's Piccolo, and while the drive does not include a dedicated DRAM cache, it uses a 64MB Host Memory Buffer (HMB) to achieve performance levels comparable to DRAM-equipped models in most scenarios.
The manufacturer provides a 5-year limited warranty or 1,200TB TBW, whichever comes first. This endurance rating translates to roughly 0.66TB of writes per day over five years, which is more than sufficient for typical gaming and general computing workloads.

## Best Use Cases
- Content creators who work with large video files or RAW photo libraries. The 2TB capacity and high sequential speeds handle 4K footage and batch exports comfortably. Professionals doing sustained heavy writes daily might prefer a DRAM-equipped drive.
- Users running out of storage space for modern game installs. With many AAA titles exceeding 100GB, 2TB provides room for a substantial library. Those seeking absolute minimum load times should consider higher-end PCIe 5.0 x4 drives instead.

## Things to Consider
This drive uses an HMB design rather than a dedicated DRAM cache. For gaming and everyday computing, the difference is barely noticeable, but sustained heavy write workloads can cause performance to drop below what a DRAM-equipped drive would sustain. If your workflow involves continuous large file transfers for hours, consider the 990 PRO instead.
While the drive supports PCIe 5.0 x2, the maximum transfer speed is the same whether connected via PCIe 4.0 x4 or PCIe 5.0 x2. On PCIe 3.0 systems, however, throughput will be significantly limited, so upgrading an older platform may not yield the advertised performance benefits.
Compared to the 990 PRO, this drive trades some random performance and sustained write endurance for a lower price. For most gamers and general users, the 990 EVO Plus offers the better value proposition.
