DELL 405-ABCS raid controller accessory

Product Overview

AI-generated summary

At £518.50 ex‑VAT for a “RAID controller accessory” (rather than the controller itself), this is one of those Dell bits that can be great value *only if* you’re matching the exact part for an existing array. If you’re trying to fix a specific compatibility issue—say you’ve got a Dell server/storage setup that expects this exact accessory—then it’s the safe, low-drama route. Dell parts tend to be boring in the best way: they slot into the ecosystem cleanly and you avoid the kind of controller/firmware mismatch headaches that waste more time than the part costs.

That said, I wouldn’t buy it speculatively. If you’re building out new storage, replacing an unknown/failed controller, or you’re not 100% sure what it’s for in your current chassis, this price starts to look steep for something that may not deliver any tangible improvement—especially since you’ll still need the rest of the RAID stack to be correct. Bottom line: buy it only if your Dell tooling or support documentation tells you *this* accessory is required for your exact model/array; otherwise, it’s probably better to spend that money on the actual missing component (or get the part number checked first).
