Product overview
Synology lists HAT5320-4T as an Enterprise 4TB 7200RPM SATA 3.5-Inch hard Drive. Carriers and caddies are chassis-specific and are almost never included with a bare drive; this is 3.5-Inch. Give us the server model and we will quote the carrier alongside it instead of letting it hold up the swap.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
The order is placed against HAT5320-4T, not against a description of it, so there is no room for a substitution you did not agree to.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Spares held to a fleet standard
Tell us the chassis you run and we will keep the spare consistent with what is already in the shelf.
Questions buyers ask about this part
- Is HAT5320-4T genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will HAT5320-4T work in my server?
- Send the server model or the shelf it is going into. Vendor-keyed firmware is the usual reason an identical-looking drive is rejected, so we check that alongside interface and form factor.
- 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.

Specifying a system, not just the part?
Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
