Product overview
This is the Synology plus HAT3300 4TB 5400RPM SATA 3.5-Inch HDD, order code HAT3300-4T. 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.
Priced per unit, with tiered pricing at quantity. Send the number you need and we will come back with the banded price.

What you get ordering this from us
Ordered by part number
The order is placed against HAT3300-4T, not against a description of it, so there is no room for a substitution you did not agree to.
Firmware family matched
A mechanically identical drive with the wrong firmware is rejected by the controller; we check the family, not just the capacity.
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 HAT3300-4T 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 HAT3300-4T 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.
