This article covers ADATA 1TB SSD Legend 800 NVMe PCIe Gen4 x 4 M.2 2280 内蔵ソリッドステートドライブ 最大3.
Overview
The ADATA Legend 800 1TB SSD is an M.2 2280 NVMe drive built on the PCIe Gen4 x4 interface. It delivers sequential read speeds up to 3,500 MB/s and write speeds up to 2,800 MB/s, placing it firmly in the entry-to-mid-range segment. Using 3D NAND flash, the 1TB variant offers a rated endurance of 1,200 TBW and comes with a 3-year limited warranty. Priced around ¥45,788 in Japan, it competes directly with other budget Gen4 SSDs like the Crucial P3 Plus and Kingston NV2. For everyday tasks like OS booting, application loading, and game level transitions, the performance is more than adequate.
Compatibility Guide
The Legend 800 uses the standard M.2 2280 form factor and connects via PCIe Gen4 x4, with full backward compatibility to PCIe Gen3 slots (though speeds will drop to Gen3 levels). It works with any motherboard or laptop that has an NVMe M.2 slot, regardless of chipset or CPU socket. For laptops, check whether the drive is single-sided (the Legend 800 is likely single-sided, but confirm with ADATA) to ensure it fits in slim chassis. The drive supports Windows 10/11, Linux, and macOS. It is not recommended for PS5 expansion due to the lack of an included heatsink.
Product Info
Released around 2023, the ADATA Legend 800 targets budget-conscious users who want Gen4 speeds without paying a premium. The 1TB model offers 3,500 MB/s reads and 2,800 MB/s writes, which is sufficient for fast OS booting, application loading, and game level transitions. It lacks a dedicated DRAM cache, relying instead on Host Memory Buffer (HMB) to use system RAM as a cache. The 3-year warranty and 1,200 TBW endurance are typical for this price tier. Available in 500GB, 1TB, and 2TB capacities. The NAND type is 3D NAND (specific cell type not disclosed).
Best Use Cases
Gamers upgrading from SATA or Gen3 SSDs: If your motherboard supports Gen4, this drive will noticeably reduce load times in modern games. It's a cost-effective way to speed up your primary drive without jumping to Gen5. Budget content creators: For photo editing, 1080p video editing, and general productivity, the read speed is ample. However, if you frequently write large video files (e.g., 4K ProRes), consider a DRAM-equipped model for sustained write performance. Secondary storage or NAS cache: The drive's price per GB is attractive for use as a game library drive or as a read cache in a NAS. Avoid using it as a write cache in high-write environments. Budget-first buyers: If you want the cheapest Gen4 SSD available and don't mind modest write speeds, this is a solid pick. But if random write performance matters, spend a bit more on a DRAM-based drive.
Things to Consider
The lack of a DRAM cache means random write performance may be lower than DRAM-based SSDs under heavy multi-threaded workloads. The sequential write speed of 2,800 MB/s is modest for Gen4; competitors like the Crucial P3 Plus offer faster writes (up to 3,500 MB/s) but often use QLC NAND with lower endurance. The Legend 800 uses 3D NAND (likely TLC), which gives it a better endurance-to-price ratio. Also, no heatsink is included, so if you install it in a PS5 or a high-airflow desktop, you may want to add an aftermarket heatsink. For laptop use, verify the drive's single-sided design to avoid clearance issues. ## FAQ
Q: Can I use this SSD in a PS5? A: Physically it fits, but the PS5 requires a heatsink and the drive must meet Sony's performance criteria. ADATA does not list the Legend 800 as PS5-compatible, so use at your own risk with a third-party heatsink. Q: Does it have a DRAM cache? A: ADATA does not specify a DRAM cache. It likely uses HMB (Host Memory Buffer), which borrows system RAM. For typical desktop use, this is fine; for heavy server workloads, a DRAM-equipped SSD is recommended. Q: How long will the drive last? A: The 1TB model has a 1,200 TBW rating. Assuming an average daily write of 50GB, it would last over 65 years. Even at 100GB/day, it's over 30 years. Endurance is not a concern for normal users.
