Plan around 2TB mirrored space
Choose the 4TB package for a mirrored library that fits comfortably below 2TB, allowing room for growth and backup versions. Deletion, malware and a lost enclosure still require a separate backup.[1]

Is it a good fit?
4TB populated shared storage
Drives included and 1GbE file access for a small household or office; capacity planning depends on RAID.[1]
A backup destination
Keep a separate copy and verify restore behavior; RAID alone is insufficient.[1]
macOS 26 Time Machine
Buffalo KB6060 lists LS200 as not compatible.[2]
Containers, VMs and transcoding
The cited documents do not establish these workloads for this exact appliance.[1]

Living with it
What matters in everyday use
What the 1GbE port changes
One Gigabit Ethernet port and USB 2.0 favor routine sharing and scheduled copies. Large restores and frequent transfers deserve more time; link rate is not measured file speed.[1]
Check your Mac backup version first
Buffalo lists the LS200 family as not compatible with macOS 26 Time Machine. An existing AFP backup continuing to work is not evidence that a new setup is supported.[2]
A storage appliance with a defined scope
The reviewed documents describe file sharing, USB backup and WebAccess. They do not establish Docker/VM hosting, NVMe expansion or hardware-transcoding performance for this unit. Choose a documented app-capable NAS if those are core requirements.[1]
What remains unmeasured
The adopted test covers one historical factory 4TB sample. Current HDD revisions, firmware and network conditions can change results.[4]
Related empty-chassis LS220D lab (not this carton)
ServeTheHome (2016) tested an empty LS220D with two user-installed 4TB WD Reds. ATTO RAID 1 prose cites about 55 MB/s writes and 50–95 MB/s on the same chart sentence; idle 12.413 W and peak 15.424 W on a Yokogawa WT310. That is the older diskless LS220D, not the factory SoHo LS220D0402B 2×2TB WD Blue sample TweakTown used.[7]

Observed file-transfer behavior
With two 2TB WD Blue drives, SMB writes were 27 MB/s in RAID 0 and 24 MB/s in RAID 1 (10GB file). Plan for modest write throughput.

LinkStation SOHO 4TB NAS Review
Updated Nov 3, 2020
Tested: Two 2TB WD Blue HDDs, RAID0/1, SMB. Test-system list: Ryzen 5 3600, ASUS X570, 16GB DDR4-3600, MP600 1TB, Windows 10. DiskBench screenshots record the file size and transfer direction.
Applies to: Exact enclosure and capacity; original drive revision and firmware may differ from current stock.
- The modest SMB speeds suit basic file sharing; these factory-drive results do not predict other capacities or replacement disks.Source location: Original figures20–22 and conclusion
| Measurement | Result | Conditions & source location |
|---|---|---|
| RAID0 / RAID1 SMB write | 27.767 / 24.522 MB/s | DiskBench C→Z, 10,737,418,240-byte file; 368788 / 417587 ms.Original figure20 |
| RAID0 / RAID1 SMB read | 51.799 / 49.553 MB/s | DiskBench 599,259,760-byte file, 32MB blocks.Original figure21 |
| Two simultaneous SMB reads | RAID0: 33.192 and 34.484 MB/s; RAID1: 25.742 and 26.158 MB/s | Each file is 599,259,760 bytes; separate per-file rates, not one-file throughput.Original figure22 |
Limits to keep in mind
- One historical sample; no fleet reliability evidence.
- Do not transfer results to other capacities or replacement drives.
- Original charts now read; transfer-window results describe these historical runs.
- Article says two-year warranty; current official SoHo warranty is three years. Affiliate links disclosed; loan/gift unknown.

Before you buy

Budget for recovery and regional support
The current US warranty table lists three years for this family. Keep the receipt; warranty replacement does not protect or guarantee recovery of your files.[3]

Questions before buying
How much of the 4TB can I use?
With two equal disks in RAID 1, plan for about 2TB before formatting and system overhead. RAID 0 exposes more capacity but has no disk-failure tolerance.[1]
Does LS220D0402B support new macOS 26 Time Machine backups?
Buffalo KB6060 lists LS200 as not compatible. Do not rely on the generic legacy Mac/Time Machine wording in the product brochure.[2]
Is the HDD model supplied in the box guaranteed?
The exact current-stock HDD revision is not guaranteed in the reviewed documents. Historical review samples do not establish what a new order contains.[1]
Can I add memory, SSD cache or containers later?
No supported upgrade path or container-host workload was established in the cited US documents. Buy this configuration for its documented file and backup functions.[1]
What does the B suffix mean for warranty?
The current Buffalo Americas warranty table lists 3 years for SoHo. Check US seller eligibility and retain proof of purchase.[3]
Does remote access replace a backup?
No. WebAccess provides another way to reach the same stored files. It does not create a separate copy that survives device loss or data deletion.[1]
