在过去18至24个月内，消费和专业级网络附加存储（NAS）市场经历了显著的设计转变。1以Synology等主要制造商为首，这些企业采取了一系列硬件优化措施，包括焊接内存、限制硬盘兼容性和集成固定启动盘等，旨在降低生产成本。1这些改动的结果是，NAS从开放模块化的存储节点逐步演变为功能受限的封闭锁定设备，用户的长期所有权和可维修性能力大幅下降。1
在具体设计层面，问题表现得更为明显。x86平台NAS普遍采用焊接LPDDR内存，无法进行升级，一旦内存芯片故障便需要更换整个主板。1许多中档NAS产品仍然配置1GbE网口，而2.5GbE已成为主流消费级主板的标准配置。1Synology等厂商实施了硬盘验证政策，限制第三方驱动器的使用或在兼容性检查失败时禁用相关功能。1制造商还采用低容量M.2 2230固态硬盘或直接焊接UFS 3.1作为系统盘，这占用了原本用于扩展的槽位。1PCIe通道配置存在明显缩水，M.2槽和网络控制器运行在Gen 3 x1或x2配置而非标准的x4规格。1
供应链和产品迭代策略进一步加剧了这一趋势。多个厂商重新发售2至4年前的硬件，仅进行表面改动（如将1GbE升级至2.5GbE）作为新产品。1硬盘市场的供应紧张导致低端1-2TB和高端16TB以上容量的选择被挤压，消费级购买者的选项受到限制。1此外，无DRAM的NVMe固态硬盘在持续工作负载下出现性能下降问题。1
Consumer and professional-grade network-attached storage (NAS) systems have undergone significant design changes over the past 18 to 24 months, with manufacturers implementing cost-cutting measures that have transformed these devices from open, modular systems into increasingly locked-down products 1. The shift reflects a broader trend toward reducing long-term repairability and user ownership flexibility across the NAS market.
Manufacturers have adopted multiple strategies to lower production costs while limiting user upgrades and modifications. Memory components on x86-based NAS systems are now commonly soldered directly to motherboards as LPDDR memory, making them non-upgradeable and requiring full motherboard replacement if a memory chip fails 1. Similarly, makers are integrating system storage using low-capacity M.2 2230 solid-state drives or soldered UFS 3.1 chips that occupy expansion slots otherwise available for user storage 1. Synology and other vendors have implemented drive validation policies that restrict or disable functionality when third-party drives are used 1. Additionally, many mid-range NAS models still feature 1-gigabit ethernet ports despite 2.5-gigabit connectivity becoming standard on consumer-grade motherboards 1.
Technical constraints compound these design limitations. PCIe lanes are severely insufficient on many current models, with M.2 slots and network controllers operating at Gen 3 x1 or x2 speeds rather than the standard x4 configuration 1. NVMe solid-state drives without DRAM cache experience degraded performance under sustained workloads 1. The broader storage market has further narrowed consumer choices, as supply constraints have squeezed availability of both low-capacity drives at 1–2 terabytes and high-capacity models at 16 terabytes and above 1. Some manufacturers have also repackaged hardware from two to four years prior with only surface-level updates, such as upgrading from 1GbE to 2.5GbE connectivity 1.
