This article covers (ウエスタンデジタル) Western Digital 2TB WD Green SN350 NVMe 内蔵SSD ソリッドステートドライブ.

Overview

Western Digital's WD Green SN350 2TB (model WDS200T3G0C) is an entry-level NVMe SSD in the M.2 2280 form factor, offering sequential read speeds up to 3,200 MB/s. This makes it roughly four times faster than a typical SATA SSD, providing a noticeable boost in everyday PC tasks. With a generous 2TB capacity and a price tag around ¥44,000 (approx. $300 USD), it targets budget-conscious users who want to breathe new life into an older system without breaking the bank. The drive uses 3D QLC NAND flash, which keeps costs low while enabling high capacities. It lacks a dedicated DRAM cache but supports Host Memory Buffer (HMB) to leverage system RAM. The included Western Digital SSD Dashboard software lets you monitor drive health, temperature, and usage, adding peace of mind for long-term use. For light office work, web browsing, and media consumption, this SSD delivers a smooth, responsive experience.

Compatibility Guide

The WD Green SN350 2TB uses the standard M.2 2280 form factor and connects via NVMe PCIe Gen3 x4. It is compatible with any motherboard or laptop that has an M.2 slot supporting NVMe (not just SATA). Form factor: M.2 2280 (22mm wide, 80mm long) Interface: NVMe PCIe Gen3 x4 OS support: Windows 10/11, macOS, Linux Power: Powered directly by the M.2 slot, no extra cables needed Be sure to check your motherboard manual to confirm NVMe support in the M.2 slot. Some older boards only support SATA M.2 drives.

Product Info

The WD Green SN350 2TB was released in 2021 as part of WD's budget-friendly Green lineup. It sits firmly in the entry-level tier, prioritizing affordability and capacity over raw performance. The 2TB variant offers a TBW (Total Bytes Written) rating of 100TB, backed by a 3-year warranty. Capacity: 2TB (2000GB) Sequential Read: up to 3,200 MB/s Sequential Write: up to 2,200 MB/s (2TB model) NAND: 3D QLC NAND Controller: Western Digital proprietary DRAM cache: No (HMB supported) TBW: 100TB MTBF: 1.75 million hours * Warranty: 3 years

Best Use Cases

Budget PC upgrades for home users: If you're still running an HDD or a SATA SSD, swapping to the SN350 will dramatically improve boot times and application loading. It's a cost-effective way to modernize an older desktop or laptop. However, if you already have a decent NVMe Gen3 drive, the upgrade benefit is negligible. Secondary bulk storage drive: The 2TB capacity is excellent for storing games, photos, videos, and documents. It works well as a secondary drive for reads, but heavy write workloads (e.g., downloading large files constantly) may wear out the QLC NAND faster than a TLC drive. * Office and productivity machines: For tasks like email, spreadsheets, and web browsing, the SN350 offers more than enough speed. It runs cool and quiet, making it ideal for silent PCs. Users who perform frequent large file transfers or run virtual machines should consider a higher-end drive with DRAM and better write endurance.

Things to Consider

The WD Green SN350 uses QLC NAND, which can slow down significantly during sustained large writes. Without a DRAM cache, random I/O performance is lower than DRAM-equipped SSDs. For an OS drive, this might lead to occasional stuttering under heavy multitasking or when the system is low on RAM. Competitors like the Crucial P3 Plus (Gen4, TLC) or Kingston NV2 (QLC, DRAM-less) offer similar pricing. If your motherboard supports PCIe Gen4, the P3 Plus provides better future-proofing and write endurance. The SN350's strong suit is its low cost per gigabyte for 2TB, making it a solid choice for bulk storage or light OS use. ## FAQ
Q: Can I use this SSD in a PS5? A: No. The PS5 requires a PCIe Gen4 NVMe SSD for internal storage. The SN350 is Gen3 and is not compatible as a PS5 upgrade drive. For PS5, look for a Gen4 SSD like the WD Black SN850. Q: Is it suitable for a laptop upgrade? A: Yes, as long as your laptop has an M.2 2280 slot with NVMe support. Check if the drive is single-sided; many laptops require single-sided SSDs. The SN350 is likely single-sided, but verify before purchase. Q: How long will the drive last for daily use? A: With a TBW of 100TB, a typical user writing 20-30GB per day can expect the drive to last 5-10 years based on the wear level. Heavy users (e.g., downloading 100GB+ daily) may see reduced lifespan. The 3-year warranty covers defects, not wear-out.
