Chinese motherboard manufacturers regularly please us with very innovative solutions, for example, an Intel X99 motherboard with DDR4 and DDR3 memory support, or an Intel H310C motherboard with support for four generations of Intel chips at once. And another creation of a gloomy Chinese genius was the Onda B250 D32-D3 motherboard, which supports connecting up to 32 drives with a SATA interface.
The Onda B250 D32-D3 motherboard has dimensions of 405.5 × 310.5 mm, which does not correspond to any standard form factor of motherboards. The board is located immediately 32 SATA ports, and here are used twin ports for data transfer and for power, as in laptops. The drive to this connector can be connected either directly or through an adapter. In any case, you will need some kind of non-standard case to accommodate all this.
The novelty is built on Intel B250 system logic, and its bandwidth is clearly not enough to connect such a large number of SATA drives. Therefore, the manufacturer used some additional controllers, however, it is not specified which ones. In the photos of the Onda B250 D32-D3 board, you can notice some chips from Marvell.
We also note that since the novelty is built on the Intel B250 chipset, it only supports older processors of the Skylake and Kaby Lake generations performed by LGA 1151. It is also interesting that the Onda B250 D32-D3 is not equipped with the usual 24-pin ATX connector, but instead There are six 6-pin PCIe slots. There is also a pair of slots for DDR4 SO-DIMM memory modules, PCI Express 3.0 x1 expansion slots and a connector for connecting USB 2.0 ports. The rear panel has two network ports, four USB 3.0 ports and one HDMI and D-Sub video output.
The motherboard Onda B250 D32-D3, as well as its version B250 D32-D3 IPFS, are sold in China at a very impressive price of 3300 yuan, which is approximately equal to $ 465 or almost 30,000 rubles.
