Product overview
Part number X477A-R6 identifies this NetApp 4TB 7200RPM SAS 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.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
X477A-R6 is what is quoted and X477A-R6 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.
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 X477A-R6 genuine and is the warranty intact?
Yes, new and sealed, with the NetApp warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will X477A-R6 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, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

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