Test setup, measurements & limitations
BUFFALO LS710D0401 LinkStation as DLNA server and PC backup
Tested: Purchased LS710D0401 4TB Japan retail; CrystalDiskMark 8.0.4 x64 Admin, 5 runs, 1 GiB, folder selection, MB/s; author 1 Gbps home LAN; NAS 1F / desktop 2F; screenshot CrystalDiskMark_20230107173407.png.
Applies to: Direct first-hand use of LS710D0401, the same MPN as the US 4TB SKU. Japan firmware/apps and 1 GbE LAN. Chart unit is MB/s. Not a 2.5GbE measurement and not the US bundled HDD guarantee.
- Retail box printed 234 MB/s read, 188 MB/s write and 2.5G hexa-core CPU — manufacturer claims, not this 1 GbE CDM result.Source location: Unboxing / 外箱 paragraphs

Limits to keep in mind
- Japan retail sample; firmware version and client NIC model not recorded.
- Folder target; drive occupancy not visible on the screenshot.
- Author speculated hexa-core CPU caused faster random I/O and DLNA browsing — not adopted.
- Rakuten affiliate image at the end; gift/cash unknown.
