Product overview
The QNAP 4-Bay rackmount USB 3.0 RAID expansion unit is supplied under part number TR-004U. Drives, carriers and the enclosure are separate line items, and a shelf that arrives without carriers cannot be populated. Tell us the drive count and we will quote the whole shelf.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

What you get ordering this from us
Ordered by part number
TR-004U is what is quoted and TR-004U is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Supported by the head unit
We confirm the shelf is on the controller’s supported list, not merely that the cable fits.
Questions buyers ask about this part
- Is TR-004U genuine and is the warranty intact?
- Yes — new and sealed, with the QNAP warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will TR-004U work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.
