16 SSD hard disk combination: power consumption 230W, speed is a bit exotic

SSD hard disk is indispensable. Do you think 1-2 SSD hard disks are not enough?Apex is crowdfunding a storage scaler expansion cardUp to 16 m.2 SSD hard disks can be installed, and the maximum power consumption is 230W.

Although there are many PCI e hard disk expansion cards on the market, the number of hard disk bits is usually no more than 4, and a few can reach 8. The storage scaler should be the first one with 16 SSDs. The storage scaler can install 16 m.2 hard disks, and there are two groups of 4xssd array bits on both sides.



In order to make 16 SSDs work normally, storage scaler designed a powerful PCB circuit,The maximum power supply is 230W, but the typical power consumption is only 80W. It uses the PCI 4x slot and has four sff-8643 SATA 3 / SAS interfaces.




The company uses 16 512gb Samsung 850 hard disks for demonstration, forming an 8tb array, with a reading speed of 7377mb / s and a writing speed of 5712mb / s. The continuous reading and writing performance is very strong.

However, the random performance of 4K is only 21.9mb/s, which is very weak now,The reason is that this expansion card only supports m.2 hard disk in SATA mode, and does not support nvme hard disk, so its performance is limited.


This also makes it very embarrassed. The combination of 16 weak chicken SATA mode SSD hard disks will only increase their capacity, improve their continuous read-write speed, and have little improvement in 4K random performance, even far inferior to the current nvme hard disk.

In addition,This expansion card does not have its own raid master. It is either connected through the mode of HbAS or matched with other raid controllers, so it is also a bit weak.

The company's crowdfunding target is $50000. Currently, it has raised less than $10000 and only 27 supporters. It has 23 days to go before it can get a refund.
