This article covers Western Digital(ウエスタンデジタル) 500GB WD Blue SN570 NVMe 内蔵ソリッドステートドライブSSD.

Overview

The Western Digital WD Blue SN570 is a PCIe Gen3 x4 NVMe SSD that strikes an excellent balance between price and performance. The 500GB model (WDS500G3B0C) delivers sequential read speeds up to 3,500MB/s, making it a solid upgrade over SATA drives for everyday computing and light gaming. It's a single-sided M.2 2280 drive, ensuring compatibility with a wide range of laptops and desktops. WD Blue SN570 is positioned in the entry-to-mid range of the NVMe market. It uses TLC NAND flash, which offers better endurance compared to QLC-based competitors. The drive also comes with Western Digital's SSD Dashboard for monitoring health and firmware updates, adding a layer of convenience for users who want to keep their storage in top shape. With a 5-year warranty and a TBW rating of 150TB for the 500GB variant, the SN570 is a reliable choice for budget-conscious builders looking for a performance boost without breaking the bank.

Compatibility Guide

The WD Blue SN570 is a standard M.2 2280 NVMe drive that works with any system having a PCIe Gen3 x4 (or higher) M.2 slot. It is backward compatible with PCIe Gen4 slots, operating at Gen3 speeds. Form factor: M.2 2280 (single-sided) Interface: NVMe 1.3 / PCIe 3.0 x4 Supported OS: Windows 10/11, macOS, Linux Note: Some older chipsets (e.g., Intel 6-series, AMD A320) may not support NVMe boot. Always check your motherboard manual. For example, pairing it with a B560 motherboard and an Intel Core i5-11400 will allow the drive to reach its full speed. It is not compatible with PlayStation 5, which requires a Gen4 drive.

Product Info

Released in 2021, the WD Blue SN570 is a mid-range NVMe SSD from Western Digital. The 500GB model (WDS500G3B0C) has the following key specs: Sequential read: up to 3500 MB/s Sequential write: up to 2300 MB/s (500GB model) Random read (4K): up to 460,000 IOPS Random write (4K): up to 450,000 IOPS TBW: 150 TB Warranty: 5 years (limited by TBW) Market positioning: entry-to-mid range. It competes with Samsung 980 and Crucial P3, but uses TLC NAND for better endurance. The WD SSD Dashboard is a nice bonus for maintenance.

Best Use Cases

Everyday PC users: Ideal for boot drives and general applications. The speed jump from SATA is very noticeable for tasks like opening browsers, office suites, and file transfers. Budget gamers: Good for game load times, though Gen4 drives offer slightly faster loading in some titles. The SN570 is perfect for those building a budget gaming rig with a B550/B560 motherboard. * Secondary storage or cache: For use in a secondary PC, NAS cache, or scratch disk. The 150TBW endurance is sufficient for moderate write workloads. Not recommended for heavy server logging or constant large file transfers.

Things to Consider

The WD Blue SN570 lacks a DRAM cache, relying on HMB (Host Memory Buffer) to improve performance. This can cause slowdowns during sustained heavy writes, but for most users, the difference is negligible. If you frequently move large files (100GB+), consider a DRAM-equipped drive like the WD Black SN770. Write speed on the 500GB model is 2300 MB/s, which is slower than the 1TB version (3000 MB/s). If you need faster writes, the 1TB variant is a better choice. Competitors include Samsung 980 (also DRAM-less) and Crucial P3 (QLC). The SN570's TLC NAND gives it a durability edge, though prices are similar. Also, ensure your motherboard M.2 slot is PCIe Gen3 or Gen4; older SATA-only M.2 slots will not work. ## FAQ
Q: Can I use the WD Blue SN570 in a PS5? A: No, the PS5 requires a PCIe Gen4 SSD. The SN570 is Gen3, so it won't work. For PS5 storage, look at the WD Black SN850P or similar Gen4 drives. Q: Does the lack of DRAM affect everyday use? A: For most tasks like booting, gaming, and general use, HMB handles it well. You won't notice a difference. Only under heavy sustained writes (e.g., copying 200GB files) might you see a performance drop. Q: Is 500GB enough for a gaming PC? A: It's enough for OS, a few apps, and maybe 2-3 modern games. Many AAA games now exceed 100GB, so if you plan to install multiple titles, consider the 1TB model.
