1PB computing power

1. You can consult linkzol
this depends on your computing application hardware. If computing is purely dependent on CPU or GPU computing power
for the computing power of CPU, it is the superposition of pure CPU's double precision computing power, and it is the same for GPU
in addition, we should consider whether your computing software supports GPU computing power. If a pure CPU costs 1 Pb, then the budget is much larger. GPU is different. A card such as titanx has a single precision computing power of 11T flops.

2. In this era, it is impossible for a single hard disk to be 1PB. What we need is a server, which is a pile of hard disks. Then we rely on the server operation to make the pile of hard disks into a whole. 1PB is about 100 10t hard disks, 3000 yuan each. The optical hard disk is 300000 yuan, and the server including the transmission network is tens of thousands, so 1PB hard disk is 400000 yuan in theory
in addition to 1eb, this is not so simple. This is 1000 times of the above. First of all, 400000 × 100 = 400 million, and then you need a set of very advanced transmission system to connect them. Because the data is too large, the ordinary transmission method may not be able to read it for a year. You need to cooperate with high bandwidth, optical fiber, processor with strong computing power and so on to make such a large database become a whole and a "hard disk". Therefore,
this hard disk may be at least 1 billion to buy, because it is not available now, so people need to design and make a special one.

Hard disk is one of the main storage media of computer, which is composed of one or more aluminum or glass discs. The disk is covered with ferromagnetic material
the hard disk includes solid state hard disk (SSD disk, new hard disk includes SATA solid state, m.2 solid state, PCI-E solid state, and m.2 solid state has nvme m.2 and SATA m.2), mechanical hard disk (HDD traditional hard disk has 3.5 inch, 2.5 inch, 5400 rpm and 7200 RPM)
4. The main mixed operation procts are more and more comprehensive, and adapt to economic development
so mixed operation is the trend,
how to develop commercial banks
since the 1980s, affected by financial liberalization, electronic and information technology, the operation mode and competition pattern of global commercial banks have been in rapid development and change. In contrast, the formation of China's commercial banks' organizational system, the rise of market-oriented competition, and the evolution of management and competition pattern are mainly driven by the graal reform of economic and financial system< Since the 1980s, China's reform and opening-up policy has injected great vitality into the development of the financial instry. From the reconstruction of the financial system, the realization of financial macro-control to the full implementation of the market-oriented reform of the financial sector, China's financial reform has gone through an extraordinary road of development. With the pace of the reform and development of the overall financial system, China's commercial banking instry from scratch, growing and standardized, performing a dynamic chapter of reform
first, the establishment of "professional banks" marks the emergence of the rudiment of China's commercial banking system. In the early 1980s, the pattern that the people's Bank of China "dominates the whole country" and that the central bank and commercial banks "are not separated from each other" was broken, forming a professional banking system composed of Bank of China, construction bank, instrial and Commercial Bank of China and Agricultural Bank of China. This is the initial form of China's commercial banking system.
