Product overview
ST6000NE0021 is a Seagate 6TB 7200RPM SATA 6Gb/s 3.5-in hard Drive. Rebuild time scales with capacity, so a large drive in a parity group is a longer window of exposure — this one spins at 7200RPM. Tell us the RAID level and group size and we will say plainly whether the geometry still makes sense.
This part is quoted rather than listed, because the price moves with availability. Send the quantity and we will come back with a number we can stand behind.

What you get ordering this from us
Ordered by part number
ST6000NE0021 is what is quoted and ST6000NE0021 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
- Is ST6000NE0021 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 ST6000NE0021 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.
