MINISFORUM, a company known for its mini-PCs, has officially launched its new PCIe expansion card, the ESP4B, now available on e-commerce platforms. Priced at 669 yuan (approximately $92 USD), this card aims to significantly boost storage connectivity for desktops and servers.
Unpacking the ESP4B’s Connectivity
At the heart of the ESP4B lies the ASMedia (祥硕) Promontory 21 (ASM2824) controller. This robust chip is the driving force behind the card’s impressive array of interfaces. The ESP4B features active cooling to ensure stable performance even under heavy load.
The expansion card boasts a total of four M.2 slots. These slots can be configured in different ways: two can operate as PCIe Gen4 x4 interfaces, suitable for high-speed NVMe SSDs, or all four can function as PCIe Gen3 x2 interfaces, offering broader compatibility with various M.2 devices.
In addition to the M.2 slots, the ESP4B provides four SATA III ports. These are achieved through PCIe Gen3 lanes, which are converted via OCuLink 4i connections. This setup allows users to connect traditional SATA HDDs or SSDs, expanding their storage options considerably.
Leveraging PCIe for Maximum Throughput
The Promontory 21 chip itself connects to the system via four PCIe Gen4 lanes upstream. Downstream, it utilizes a combination of PCIe lanes. The M.2 slots draw their bandwidth from PCIe Gen4, while the SATA interfaces are provisioned through PCIe Gen3.
Furthermore, the ESP4B includes a single USB port offering a 20Gbps Type-C connection. This provides a high-speed link for external devices or other compatible peripherals.
Target Audience and Use Cases
The MINISFORUM ESP4B is designed for users who need to expand their storage capabilities beyond the standard motherboard offerings. This includes:
- Content Creators: Requiring fast access to large video files and project assets.
- Gamers: Needing ample space for extensive game libraries and quick loading times.
- Small Business Servers: Seeking to add more hard drives or SSDs for data storage and redundancy.
- Workstation Users: Demanding flexible and high-capacity storage solutions.
The ability to mix and match high-speed NVMe SSDs with traditional SATA drives offers a versatile storage configuration. The inclusion of active cooling is a welcome feature, addressing potential thermal throttling issues that can plague high-density storage setups.
Availability and Pricing
The MINISFORUM ESP4B expansion card is currently available for purchase on JD.com and potentially other e-commerce platforms, with a retail price set at 669 yuan.
This release from MINISFORUM underscores the growing demand for flexible and high-performance storage expansion solutions in the PC market. As storage needs continue to grow, cards like the ESP4B will play a crucial role in enabling users to scale their systems effectively.
