Product overview
HAT5310-20T is a Synology HAT5300 20TB SATA 3.5-Inch hard Drive. Rebuild time scales with capacity, so a large drive in a parity group is a longer window of exposure. Tell us the RAID level and group size and we will say plainly whether the geometry still makes sense.
Tell us the deadline you are working to and we will say whether it is achievable before you commit to it internally.

What you get ordering this from us
Ordered by part number
The order is placed against HAT5310-20T, 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.
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 HAT5310-20T genuine and is the warranty intact?
Yes, new and sealed, with the Synology warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will HAT5310-20T 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.
