Product overview
TL-D400S-US is a QNAP 4-Bay LFF SATA storage Enclosure. 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.
No price is published here because the market for this part moves week to week; ask and we will give you a current one rather than a stale one.

What you get ordering this from us
Ordered by part number
Quoted and supplied against TL-D400S-US specifically, so what arrives is what your build sheet asks for.
Carriers counted with the drives
Enclosure, carriers and disks are quoted as one line so the shelf can actually be populated on arrival.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
Is TL-D400S-US genuine and is the warranty intact?
Yes. It ships new in QNAP packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will TL-D400S-US 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.
