Choosing NAS storage & drives means resolving a practical mismatch: do you need a NAS-focused drive for a larger enclosure, or a compact internal hard drive suited to NAS backups? The MDD 24TB NAS Hard Drive and Seagate Barracuda ST5000LM000 5TB serve different hardware contexts. Match the bay and intended role first, then use capacity, features, and price to make the final call.
Quick verdict
Pick the MDD when a NAS-first drive is what your enclosure plan calls for. Pick the Seagate when the role is NAS backup in a smaller internal-drive format. The difference is not simply capacity: the listed form factors and compatible-device descriptions also point to different hardware contexts. Start there, then use the price and technical values as tie-breakers rather than assuming either numerical specification automatically means better performance.
Compact comparison
| Product | Listed price | Capacity in title | Form factor | Compatible device |
|---|---|---|---|---|
| MDD 24TB NAS Hard Drive | USD 509.95 | 24TB | 3.5 in | PC |
| Seagate Barracuda ST5000LM000 5TB | USD 141.54 | 5TB | 2.5 in | Laptop |
Where each product wins
- MDD 24TB NAS Hard Drive: It wins for shoppers matching the listed Hot Swap feature or the title's 7200RPM and 512MB cache values. Those are concrete fit requirements, not proof of a performance advantage.
- Seagate Barracuda ST5000LM000 5TB: It wins when the target setup calls for the listed 5.4K RPM and 128MB cache values, or when the lower listed price is central to the decision. The numbers should be treated as matching points, since the descriptions do not establish that one is inherently superior.
Product notes
MDD 24TB NAS Hard Drive
The MDD 24TB NAS Hard Drive makes its case through a clear, specific feature: Hot Swap. That gives a shopper a concrete enclosure-related point to match, alongside the title's explicit NAS wording. The limitation is cost and condition: it is listed at USD 509.95 and marked Used. Choose MDD when Hot Swap and the NAS-focused title align with the enclosure; its price and Used condition are the main compromises for this matchup. The product is also described as a PC-compatible HDD, so the intended hardware context should be part of the decision before purchase.
Seagate Barracuda ST5000LM000 5TB Internal Hard Drive
The Seagate Barracuda ST5000LM000 5TB is a sensible match for a compact internal-drive role because its description explicitly includes NAS backups alongside laptop, small-form-factor desktop, external-enclosure, and DVR use. Its SATA III 6Gb/s interface is another concrete point for matching a system's requirements. The limitation is capacity: the stated 5TB is below MDD's 24TB, and the drive is marked Used. Its listed compatibility is Laptop, so it frames the choice differently from MDD's PC compatibility. Choose Seagate when the NAS-backup description and lower listed price matter more than the larger capacity.
Final choice by use case
For a NAS enclosure that calls for the MDD title's NAS designation, choose MDD 24TB NAS Hard Drive. Its Hot Swap feature and larger stated capacity make it the more direct fit for that use case, provided the enclosure matches the listed format and the USD 509.95 price works for you.
For NAS backups in a 2.5-inch, laptop-compatible context, choose Seagate Barracuda ST5000LM000 5TB. Its description directly names NAS backups, and its lower listed price makes it the price-side choice. Both drives are marked Used, so condition does not separate them. In short, match the bay and intended role first, then choose the drive whose capacity, features, and price fit that setup.
