The best budget storage path for most people
Direct‑Attached Storage (DAS) and drive shucking are budget-friendly storage expansion methods that plug into an existing PC or router, reuse drives you already own, and avoid the upfront cost and complexity of a full network-attached storage (NAS) system while still giving you room for multiple disks and basic data protection options.
If you want cheap storage expansion without learning NAS software, the TerraMaster D4-320 4‑bay DAS is the clear top pick. At USD 161 (approx. RM745), it turns spare HDDs and SSDs into usable storage, supports tool‑less installation, and connects over USB‑C so it works like a big external drive with your PC or even a router. For most budget NAS storage shoppers, this DAS enclosure alternative covers backup, bulk media, and cold storage needs at a far lower cost and learning curve than a full NAS box.
To keep costs down as capacity grows, pair the D4‑320 with shucked external drives for bulk terabytes, and reserve a small true NAS only for data that must be online 24/7. That hybrid NAS vs DAS balance is where most home users will get maximum value.
Top pick: TerraMaster D4‑320 — turn old drives into real storage
The TerraMaster D4‑320 is a 4‑bay DAS enclosure designed to reuse drives you already have and grow into more later. It accepts 3.5‑inch SATA HDDs, 2.5‑inch SATA HDDs, and 2.5‑inch SATA SSDs in any mix, so you can combine leftovers from past builds into one pool of storage. Installation is tool‑less, which makes it easy to hot‑swap or upgrade disks without a screwdriver. A USB‑C port on the rear connects directly to a PC or compatible device, and you can even plug it into a router to expose shared storage on your network.
At USD 161 (approx. RM745), this D4‑320 DAS enclosure is a low‑cost entry point to multi‑drive storage compared with buying a dedicated NAS chassis. The trade‑off is that it lacks the deeper services and always‑on apps of a true NAS; "although a NAS offers more versatility, a DAS can be a great solution if you just need access to your files". That makes it ideal for backups, media libraries, and archive data that you access from one main machine or a simple home network.
Who it suits: anyone with older HDDs or SSDs lying around who wants cheap storage expansion and basic RAID without running a full NAS. Who it does not suit: users who need advanced NAS apps, multi‑user permissions, and continuous uptime.

Drive shucking: the cheapest way to feed a NAS
Once you outgrow a single DAS and move toward a true NAS, the most expensive part is filling it with large drives. Shucking — buying external drives and removing the internal disk — remains one of the best sources of inexpensive storage for a NAS or PC, and "shucking remains one of the best sources of NAS drives" for servers and more. A typical external 8TB enclosure is a plastic shell, a bridge board, and the drive itself; dismantling it gives you an internal HDD at a lower drive shucking cost than a retail NAS‑branded equivalent.
You can sometimes find NAS‑class or white‑label drives inside these shells, but it is a storage lottery. You do not know in advance which exact model you will receive, and some units may be duds. Drives in external enclosures often lack workload ratings and warranties intended for always‑on NAS use; they were designed for occasional external storage instead. For non‑critical home use, those compromises can be acceptable, especially if your main goal is cheap bulk capacity rather than guaranteed 24/7 duty cycles.
Shucking makes the most sense when the external unit is significantly cheaper per terabyte than new NAS drives or refurbished enterprise disks. Always compare real price per terabyte, factor in hidden costs like adapters and extra cooling, and test each shucked drive with a burn‑in period before trusting it with important data.
Key buying checks: NAS vs DAS and hybrid strategies
When choosing between NAS vs DAS, start with your workload and budget. DAS units like the D4‑320 provide simpler setup and lower cost when you mainly need direct file access or basic backups, while a NAS adds versatility with always‑on services and multi‑user sharing. Many users get the best budget NAS storage results by combining both: a DAS enclosure alternative for bulk archives, plus a lean NAS for critical data and services.
For drives themselves, focus on three to five checks. First, compare price per terabyte across bare NAS drives, refurbished enterprise models, and external units for shucking. Second, check recording method (CMR vs SMR), drive cache size, and workload ratings so you do not end up with a slow or unsuitable disk in a RAID array. Third, confirm compatibility with your enclosure or NAS, including interface and physical mounting.
Finally, plan around hidden costs and risk. Shucking can need adapters, mounting hardware, more cooling, or a separate case, and warranty support can be harder once you break the shell. RAID is not a backup, so any setup that uses shucked or reused drives should be paired with a tested backup strategy and reliable storage for the copies that matter most.
Buy if / Skip if
- Buy the TerraMaster D4-320 if you want cheap storage expansion from spare HDDs and SSDs without learning NAS software or managing complex apps.
- Skip the TerraMaster D4-320 if you need advanced NAS features like always-on services, user permissions, and app ecosystems more than you need low upfront cost.
- Buy the TerraMaster D4-320 if you plan a hybrid setup where it starts as a direct-attached unit and later connects to a router or NAS for shared storage.
- Skip the TerraMaster D4-320 if you have no spare drives and intend to buy all-new disks, in which case a small dedicated NAS chassis may be better long-term value.
- Buy the shucked-drive approach if the external unit’s price per terabyte is significantly lower than comparable NAS drives and you are comfortable doing extra testing.
- Skip the shucked-drive approach if you are new to storage, since sticking to refurbished or brand-new drives on sale is safer and easier to manage.
- Buy the shucked-drive approach if your usage is non-critical home storage, such as media libraries or game archives, where occasional downtime is acceptable.
- Skip the shucked-drive approach if you cannot tolerate uncertainty in drive models, warranties, or early failures, or if you do not have a solid backup strategy.
