MDD 10TB Hard Drive: Live Price, the Warranty Each Listing States, and Seagate Compared
We earn a commission if you buy through the links on this page, including links to the sellers it describes. You should read everything below knowing that. What we can offer against it is method: the figures here are computed from our own price database rather than supplied by anyone, the ownership facts come from public records we link, and we publish no rating or verdict on any seller - we show you what they sell, what the warranty covers, and how to check a drive yourself.

Every MDD listing was read at source on 1 October 2026. Prices and counts last refreshed
Fewer than 3 MDD 10TB listings are in stock right now, so any comparison on this page rests on a thin field and says so. The 10TB drives you can buy today, from any brand, are listed below.
MDD is a label registered to GOHARDDRIVE, INC.; the drives are built by other manufacturers and sold under MDD's own part numbers. Who owns the label, and why no reliability data exists for it, are on the MDD reliability page. This page is about one capacity: what MDD has in stock at 10TB today, what each of those listings says about itself, and how it compares with the rest of the 10TB shelf.
MDD 10TB listings in stock
One row per product, cheapest per terabyte first. The warranty column is what each listing states; the line under the condition is the evidence for that offer. Prices are Amazon US listings, in US dollars.
Provenance describes the offer shown now, not the drive: Amazon's own condition and grade, the seller, the seller's note in their words, and what the listing title claims. It can change when a different seller holds the listing.
| MDD part number | Capacity | Interface | Condition and evidence | Warranty the listing states | $/TB | Price | |
|---|---|---|---|---|---|---|---|
| MDD10TSATA25672NAS | 10TB | SATA-6G | Used This offer: sold by Worldwide Product Importer · Amazon says New / New · title says Renewed | none stated | $28.00 | $279.99 | Buy Now |
Each listing, in its own words
MDD10TSATA25672NAS is a SATA-6G 10TB drive, used, at $279.99 ($28.00/TB). Its title says "renewed". Amazon's condition field reports it as New / New. The offer shown is sold by Worldwide Product Importer. The listing states no warranty.
Against Seagate at 10TB, matched
Where a Seagate 10TB listing is in stock at the same interface and condition as an MDD one, the two cheapest are compared per terabyte. A negative figure means MDD is cheaper. Model counts show how many distinct drives sit on each side of the match.
| Interface | Condition | MDD $/TB | Seagate $/TB | MDD vs Seagate | Models | Seagate |
|---|---|---|---|---|---|---|
| SATA-6G | Used | $28.00 | $32.00 | -12.5% | 1 / 6 | Buy Now SkyHawk AI 10.0TB |
At least one side of this match rests on a single model, so read it as one listing against another rather than as a market-wide figure. The all-capacity view, with every match and the mean and median across them, is on MDD vs Seagate.
The whole 10TB shelf, as levels
Every brand with a 10TB hard drive in stock, with its cheapest new and cheapest used price per terabyte. These are levels - the cheapest listing of each kind - not like-for-like differences: two brands' cheapest listings can be different interfaces and different drives.
| Brand | Listings in stock | Cheapest new $/TB | Cheapest used $/TB | Interfaces |
|---|---|---|---|---|
| WD | 14 | $37.17 | $20.00 | SAS-12G, SATA-6G |
| Seagate | 12 | $42.00 | $25.00 | SAS-12G, SATA-6G |
| HGST | 3 | $38.45 | $23.50 | SAS-12G, SATA-6G |
| MDD | 1 | none in stock | $28.00 | SATA-6G |
Among the 4 brands with a used 10TB drive in stock, MDD's cheapest used listing ranks 4 of 4 by price per terabyte. The other brands on the 10TB shelf today are WD (14), Seagate (12), HGST (3). At this capacity MDD lists SATA-6G drives, and 0 of its 1 in-stock listings state a warranty. Those three facts - the interface, the condition and whose warranty applies - are the decision, more than the label on the drive.
Where the MDD 10TB listings differ from each other
Only one MDD 10TB listing is in stock, so there is nothing to compare it with under the same label. Read its warranty statement and provenance line in the table above, and compare its price with the rest of the 10TB shelf below rather than with other MDD drives.
What 10TB drives give you in an array
Most people buying 10TB drives are filling a NAS or a server, so the useful number is usable space, not raw capacity. Synology documents how each RAID type turns drives into storage: RAID 1 gives the smallest drive's size, RAID 5 gives "(N – 1) x (Smallest drive size)" and RAID 6 "(N – 2) x (Smallest drive size)".
Company's own words Choose a RAID Type - DSM 7 Knowledge Center (capacity per RAID type), Synology. Read 1 October 2026.
Applied to 10TB drives: RAID 1 (2 drives) gives 10TB usable, RAID 5 (4 drives) gives 30TB usable and RAID 6 (4 drives) gives 20TB usable. At today's cheapest MDD 10TB listing ($279.99), RAID 1 costs $559.98 for the drives, $56.00 per usable terabyte, RAID 5 costs $1119.96 for the drives, $37.33 per usable terabyte and RAID 6 costs $1119.96 for the drives, $56.00 per usable terabyte. Those are drive costs only, at one listing's price; buying four drives usually means four different listings, so check each one's condition and stated warranty rather than assuming they match. For comparison, the cheapest used Seagate 10TB on the shelf is $25.00 per raw terabyte - a level, not a like-for-like match.The interface question at 10TB
Every MDD 10TB listing in stock is SATA, the interface of desktop NAS units and of every IronWolf we track, so interface is not the obstacle at this capacity. What the listings do not state is recording technology - none of them says CMR or SMR - and that is the question to put to the seller before one goes into an array. The mixing guide covers the rest of the checklist.
A cheap 10TB is a fair buy if you know what you are buying. Most MDD listings are used drives with a seller's warranty. Read the provenance line and the stated warranty for the listing you choose, check the drive's health the day it arrives, and keep it in a redundant array with a backup.
Before you buy an MDD 10TB
Settle the interface first: a SAS drive needs a SAS controller and cannot join a SATA pool, which the mixing guide covers in detail. Then read what the specific listing states about warranty, because at 10TB it differs from one MDD listing to the next - the warranty page explains whose promise it is. Recording technology is not stated by any MDD listing, so ask the seller if your array needs CMR. And on arrival, read the drive's health data inside the return window and compare it with what the listing said.
Frequently asked questions
Frequently asked questions
How much is an MDD 10TB hard drive?
The cheapest MDD 10TB listing in stock is $279.99 ($28.00 per terabyte), used, SATA-6G. We track 1 MDD 10TB listing in stock; prices are Amazon US.
What warranty does the MDD 10TB have?
It depends on the listing: of the 1 MDD 10TB listings in stock, 0 state a warranty (none) and 1 state none. A stated warranty is the seller's, not a drive maker's.
Is the MDD 10TB cheaper than a Seagate 10TB?
Matched at the same interface and condition: SATA-6G used, MDD -12.5% against Seagate (1 MDD / 6 Seagate models).
How much usable space do four MDD 10TB drives give?
Using Synology's documented formulas: RAID 5 gives (N - 1) x the smallest drive, so four 10TB drives give 30TB usable; RAID 6 gives (N - 2) x the smallest, 20TB. At today's cheapest MDD 10TB price, four drives cost $1119.96, or $37.33 per usable terabyte in RAID 5.
Is the MDD 10TB SATA or SAS?
In stock right now: 1 SATA and 0 SAS. A SAS drive needs a SAS controller and, per Synology's documentation, cannot share a storage pool with SATA drives - so check the interface of the specific listing before you buy.
Is the MDD 10TB CMR or SMR?
No MDD listing states a recording technology, and our CMR/SMR resolver has no MDD part number on record, so we show it as unknown and never assume CMR. Ask the seller before using one in a NAS.
Is the MDD 10TB new or used?
1 of the 1 in stock are used, and 1 of those titles say "(Renewed)". A listing Amazon reports as new is, on this site, "sold as new under the MDD label": MDD is a label, so it cannot carry a manufacturer's warranty.
