On March 3, Longsys, a leading semiconductor memory company, made its debut at MWC 2025 in Barcelona. Operating under the theme “New Mode of Storage Empowering Global Mobility,” the company presented a range of cutting-edge storage products, which garnered significant attention for their innovation and potential impact on global mobility.
PTM Business Model: Full-Stack Customization Service
The Product Technology Manufacturing(PTM) model was a major highlight, showcasing Longsys’ full-stack customization capabilities—from in-house controller development and product design to rigorous testing and intelligent manufacturing.
Embedded Storage for Mobile Devices: Unlocking Flagship-level Performance
Longsys presented a full lineup of embedded storage solutions for smartphones, tablets, and wearables, including high-performance UFS, QLC eMMC with in-house WM6000 controller, and low-power LPDDR5. These products cover diversified needs from entry-level to high-end, providing all-round embedded storage support for mobile intelligent terminals.
In 2024, Longsys took the lead in applying the advanced 3D QLC technology to its eMMC products and launched the QLC eMMC with in-house WM6000 controller that supports capacity options ranging from 128GB to 512GB, meeting the needs of “cost reduction and capacity expansion” for terminal applications. The overall performance has been improved by more than 30%, and the standby power consumption reaches the level of microwatts (uW), which greatly enhances the battery life of the device. At present, it has been applied in various types of smartphones.
Server Storage: Powering AI Computing, Accelerating Intelligent Future
In 2025, large model technology will transition from probabilistic generation to strong reasoning ability, driving the demand for higher storage requirements in data centers and cloud computing industries. The server storage products showcased by Longsys at MWC 2025 can effectively meet the needs of AI servers in large-scale data processing and high-efficiency computing operations.
- ORCA 4836 NVMe eSSD & UNCIA 3839 SATA eSSD – Built with 3D eTLC NAND and enterprise-grade controllers, capacities ranging from 480GB to 7.68TB, ensuring high throughput, stability, and data security.
- CXL 2.0 Memory Expansion Module & DDR5 RDIMM – Supporting PCIe 5.0, up to 192GB capacity, and 6400Mbps speeds, theoretical bandwidth of 32GB/s, enabling memory pooling and AI acceleration.
Bluetooth PSSD: Seamless Unlocking of Hidden Storage Space
The Bluetooth PSSD stood out as a highlight during live demonstrations. This slim-profile device combines ultra-low power consumption (standby power as low as 1.5mA) with shock/vibration resistance. Equipped with a USB 3.2 high-speed interface supporting both BOT and UASP protocols, it offers configurable capacities from 128GB to 1TB.
NFC PSSD: Tap to Unlock Hidden Storage Space
Similar to the Bluetooth PSSD, the NFC PSSD also focuses on privacy data protection, but is unlocked using NFC technology. Users simply tap the sensor area with an NFC-enabled smartphone, smartwatch or NFC card to unlock a specific storage area for data access, creating on-the-go privacy storage for users. The product was first announced at CES 2025 in January.
Lexar Mobile Imaging Storage: Professional Photography at its Best
In the field of mobile phone imaging storage, Lexar, a consumer storage brand under Longsys, presented the SL500 portable solid – state drive and the Professional Go solid – state drive photography kit specifically designed for iPhone photography.
Lexar SL500 Portable SSD with Magnetic Set
The product is widely compatible with a wide range of devices, providing up to 4TB of storage capacity. With the unique magnetic design, it supports the iPhone 15 Pro series and 16 Pro series to externally record ProRes 4K videos and store them as they are taken without occupying the phone’s memory, which is a great convenience for users.
Lexar Professional Go Portable SSD with Hub
The product adopts Mini small size design, one plug and shoot, easy to realize external recording ProRes 4K video, instant transmission, shooting material directly to the hard disk. Used in conjunction with the docking station, advanced professional photography, one-stop to meet professional needs such as sound and fill light, ideal for professional photographers.
Global Presence & Localized Services
Longsys continues to strengthen its global footprint. The product manufactured by its South American manufacturing and operations center, Zilia, gaining strong recognition at MWC 2025. By integrating a dual-circulation supply chain strategy, Longsys ensures efficient production, stable supply, and localized support for global customers.
As AI, 5G, and mobile storage evolve, Longsys remains committed to customized innovation and high-quality intelligent manufacturing, paving the way for smarter, more connected storage solutions.
