If the general consumers want to buy 240 gb or 240 gb SATA solid hard disk, even on the 3 c online shopping site or some computer stores online valuation site, you will find that as long as pay 3000 yuan, can buy almost a well-known brand in the market, also can choose a few using m. 2 interface SSD, there are vendors at less than 2000 yuan, the price, of course, larger capacity solid-state hard disk, the price is relatively high, but compared with the past, actually also can afford the average person, for example, has launched capacity of 1 TB, ten thousand yuan for solid state hard drive, under such a configuration, average 1 gb of storage cost down to 10 yuan.

Consumer SSD, enterprise although SSD price has always been a mystery, if used to store arrays of collocation, the unit price will change, but will be in a falling trend. Previously we have seen some flash storage array vendors Shouting cost less than $2 per GB, even less than $1.

Here the claim, however, there are still some mystery to note. Due to involving the application of the data reduction technology, so some products of the so-called whole storage space, actually refers to the data deleted after processing, data compression, and repeated by the effective capacity (effective capacity), rather than purely based on solid state hard drive hardware itself to provide the original capacity (raw capacity). For example, HPE is mentioned in the news release which issued in June, under the 3 par StoreServ storage array, for now available (usable) to provide storage space, unit holding cost per GB for $1.2 has been able to do (with a new generation of 15 TB large capacity solid state hard drive). SanDisk also launched in April this year InfiniFlash System in the new storage equipment IF150, emphasize of solid-state storage space, by to achieve cost one dollar per GB cost; Storage vendors, Taiwan also have industry as demand this year - a group of CDH Computex Computex exhibition by FlashStation FS3017, proposed per GB of storage cost is $0.52.

In addition to the main ultra-low unit holding cost, there are some manufacturers show that the flash storage array of prices. Such as EMC, published in the may new storage array Unity series, in order to emphasize enterprise can within the $18000 to buy the whole flash configuration model (exact match storage capacity, however, does not seem to have publicly); Pure Storage was launched in March FlashArray / / m10 entry-level products, the main have to find the price of $50000, if divided by the original Storage capacity of 10 TB of the aircraft collocation, is between $4 to $5 per GB.

From the point of the various dynamic storage vendors at home and abroad, low storage cost has become the main emphasis on part, and from this year, large capacity solid state hard drives are listed, is bound to further promote the phenomenon. Like samsung launched in March 15.36 TB PM1633a capacity, is an example; Micron (Micron) is based on 3 d NAND flash memory technology, was introduced in the fourth quarter of this year more than 8 TB SSD, provided to the cloud service providers, and then published in the first quarter of next year to highlight the high performance, large capacity enterprise SSD.

Storage application, however, the I/O access speed and capacity to meet demand, is just around the corner, but for data center environment dimension of shipment, you also need to consider other factors.

First of all, these storage resources can effective configuration is still a problem. Because, in the practical environment, the possible efficiency, mismanagement, for example, you really need the application of high speed I/O and a large amount of Storage space system, or service, but not necessarily can get corresponding resource, therefore, the implementation of service level to ensure (QoS) and Hierarchical Storage Management, Hierarchical Storage Management) of necessity.

In addition, the use of flash storage array size if more and more big, the derivative of the internal network traffic may follow a surge in, the current data center environment could cooperate, also need to pay attention to. Therefore, both the Internet may need to upgrade to 10 gbe, 16 gb FC, even to a higher transmission specifications, such as 100 gbe, 32 gb FC, so, it will affect the configuration of data center network infrastructure.
