Exact product identity & open questions
- Manufacturer model
- LS220D0802[1]
- US factory configuration
- 8TB total across 2 HDD(s)[1]
- SoHo / B-suffix relationship
- US SoHo SKUs add a B suffix (for example LS220D0402B) and are a different catalog product[1]
- Current included HDD revision: Exact HDD model, recording method, workload rating and firmware supplied in current inventory are not guaranteed in the reviewed US documents.
- Undocumented expansion and filesystem details: Maximum memory, internal filesystem, snapshots and third-party application hosting are not established; no such capabilities are promised.
- Applicable independent test: No accepted original test of this exact factory-populated US capacity. ServeTheHome measured an empty LS220D with two user-installed WD Red 4TB disks (ATTO RAID 1 text ~55 MB/s writes; idle ~12.4 W). TweakTown's SoHo LS220D0402B with 2×2TB WD Blue copied a 10GB file at 27/24 MB/s write (RAID 0/1) and a 600MB file at 51/49 MB/s read. Neither sample is this factory-populated US SKU.
- Video ASR and frames: YouTube extraction failed this round. tCsgfaJBI9M appears to be an LS210 2TB listing video; dPhV43m-reI is Lon.TV LS720. No listening or frame claims.
