HDD mechanical disk, SSD hard drive who has good and bad problems have long been the conclusion, now the new installed machine does not deserve SSD hard drive, then 80% is JS flickered (if the distribution is not known brand SSD, is also fooled), SSD hard disk is not There are two places that are too satisfying - one is unit price, and the other is reliability.
As for the price issue, the NAND flash price increase in the past two years has given HDD a chance to continue its life. However, the statistics show that the price of HDD hard disks is also slowly declining. The price of 8TB hard disks is reduced by 20% a year., But SSD has already accounted for 70% of sales.
To say that dissatisfaction with the HDD hard disk, in fact, there are - and now do not have expectations on the performance of the HDD mechanical disk, the current structure can not have any changes, the most dissatisfied is the HDD hard drive price ratio The price of SSDs has to be firm, especially 4TB and above of high-capacity HDDs. 8-12TB HDDs have been on sale for several years. The consumer-grade market has had very few sales, the price is still too high, and there is very little price reduction, or it is too slow. .
The South Korean parity website Danawa counts the prices of HDD hard disks in the most recent year, covering 7 models from 500GB to 8TB. In addition to the 500GB, the other 6 models have different levels of price cuts. The 8TB hard drive has dropped from the previous 576 US dollars to 370 US dollars, a 22% decrease, and the 2TB drive price has dropped by 20% from 87 US dollars.
Danawa said demand for SSDs is increasing. As a result, HDD hard disk demand has dropped, so HDD hard disk prices are falling.
According to their statistical data, SSD hard drives now account for 70% of sales, and HDD hard drives only account for 30%.
As for whether SSDs can replace HDD hard disks, there are still two schools of thought. One side thinks that as long as the SSD hard disk addresses the disadvantages of the unit's capacity and price, it will replace the HDD hard disk later. The other party thinks that everyone mainly uses the SSD to install the system, and the HDD Hard drive prices are lower, and greater capacity advantages will continue.
Both of these arguments have valid grounds, and SSDs are indeed growing rapidly. However, the price per unit of capacity is still difficult to compare with HDD hard disk. On the other hand, HDD hard drives will enter the era of HAMR technology next year, and capacity is expected to grow substantially. Seagate has already announced that it will launch 24TB hard drives. The target for 2020 is 100TB.
However, the dilemma of the HDD hard disk market is that the market is rapidly declining. Both enterprise and consumer-class markets sell much less. Western Digital and Seagate are reluctant to cut prices significantly. For example, I bought a 3TB hard drive many years ago. It has been maintained between 500-600 blocks, and it still remains.
Manufacturers are reluctant to cut prices. Consumers here have not seen much interest in HDD hard drives because of the significant increase in bandwidth. The future demand for HDD hard drives is mainly at the enterprise level, and the cloud data market is, after all, they are big. The requirements for capacity storage are still increasing. These markets are the fastest growing average capacity of Seagate drives.
