Product overview
The Dell 1.2TB 10000RPM SAS 2.5-Inch hard Drive is supplied under part number 400-ATJO. Rebuild time scales with capacity, so a large drive in a parity group is a longer window of exposure. This one spins at 10000RPM. Tell us the RAID level and group size and we will say plainly whether the geometry still makes sense.
The listed price is per unit and current; tell us the quantity and we will confirm what it holds at before you raise the order.

What you get ordering this from us
Ordered by part number
The order is placed against 400-ATJO, not against a description of it, so there is no room for a substitution you did not agree to.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is 400-ATJO genuine and is the warranty intact?
Yes, new and sealed, with the Dell warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will 400-ATJO 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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