SAS SSD storage technology is a storage technology between the traditional hard disk and memory. In IOPS, it is 50 to 1000 times faster than a regular mechanical hard disk, and it can be used in any position within one millisecond. The storage unit performs fast input/output operations.
With the deep and wide range of server applications, many important applications are seriously constrained by server hard disk IO bottlenecks, and performance can not be significantly improved, such as search engines, portals, high-volume online games, online electronic transactions, real-time airline booking, finite element analysis and other equipment transactions The more intensive, the more demanding the IOPS (how many input/output processing requests per second) is, and the IOPS plays a decisive role in the operation of the server. Although the important CPU performance and memory capacity in the server composition are exponentially improved according to Moore's Law, even the fastest 15,000-rpm hard disk drives cannot meet the increasingly demanding geometric growth requirements. ASpec's Industrial Grade SSD Solution Development Center It is recommended that an industrial SAS SSD disk array solution based on SSD server solutions be 50 to 100 times faster than mechanical hard disk IO performance.
Traditional hard drives rely on motor speed and cache to improve access to data, and random access to dense data cannot bring a qualitative improvement. Industrial-grade SAS solid-state hard disk drives overcome the limits of traditional mechanical hard disks that rely on hard disk motors to read data at high speeds, radically changing hard disk IO pairs. The biggest bottleneck of the entire server performance. The performance of search engine servers, online game servers, electronic trading servers, and high-performance computing servers has increased dramatically. It can be said that the future hard drive era SAS solid state drives and PCI-e solid state drives will be the terminators of traditional hard drives.

The main features of ASpec's industrial-grade SAS SSDs:
Performance: The ASpec Universal Industrial SAS interface will continue to perform functions such as command sequencing on SCSI hard disks. This feature allows hard disk controllers to execute commands in the most efficient order, which improves performance. The same functionality, if implemented in SATA hard drives, will depend to a large extent on processor-based calculations. In simple terms, if the SAS is capable of hardware decoding some hard disk acceleration commands, the SATA hard disk needs to be soft decoded.
Temperature support: -55°C~+105°C
Capacity support: 128GB~1TB
To adapt to the environment: wide temperature, impact, corrosion, high temperature, low temperature, salt fog, moisture and other harsh operating environment.
Speed: ASpec is a complete two-way system for industrial-grade SAS SSDs, while SATA inherits the features of IDE and is a semi-two-way communication system. Therefore, the data throughput of SAS can be double that of SATA systems.
Connections: The longer the SATA data line, the more pronounced the performance failure. In fact, according to the relevant specifications, the length of the data link of SATA should not exceed 1 meter, otherwise there may be signal failure and thus affect the use. However, the industrial-grade SAS interface completely overcomes this problem, and the longest length of its connection line can be up to six meters. This is quite a benefit for multi-drivers or users who are accustomed to external hard drives.
ASpec Unitech Industrial Grade SAS SSD Server Solution
Multiple SAS SSDs can be combined via a RAID card.
Positioning: IO-intensive industries - industry websites/online games/web hosting/search engines/portals/high-performance computing/electronic trading.
The above configurations are based on the multi-core Xeon technology of the current fastest SAS SSDs and Intel Core architecture, and create high CPU + IO rack servers to meet the geometric growth of dense IO applications. Compared with traditional mechanical hard disks, IO performance has greatly improved. ASpec's industrial-grade SAS SSDs can also help IDC server rooms, which are rising in electricity prices, plagued by costs, and are a great solution to drastically reduce electricity bills. They even redesigned traditional server chassis and reduced the existing server space. half.
Servers in classic applications, such as search engines, e-finance transactions, online games, and high-performance computing applications, require extremely high data-intensive data exchange speeds, and require higher response time for storage-intensive application servers. Mechanical hard disk SATA to SATA interface SSD to more powerful SAS SSD, from 7200 to 15000 rpm, from support for RAID 0, 5 to more advanced RAID mode, can not have a qualitative change in response time, and power consumption Increasingly, the emergence of new SSDs has seen a real leap in speed and a significant reduction in power consumption.
A Spec comparison of SAS interface and SATA interface for industrial-grade SSD
ASpec's unlicensed industrial-grade SAS SSD SSDs are designed for intensive multi-tasking and computing applications, and the product has achieved excellent results in recent evaluations of many industrial-grade SSD SSDs. The 2.5-inch industrial-grade SAS interface SSD covers four large capacity series of 128GB, 256GB, 512GB, and 1TB, with a maximum read/write speed of 520/440 Mb/s. The OPS read and write are 40000 and 50000 respectively. Read and write performance is stable and fast, and the seek time is less than 0.1 milliseconds. Supports RAID with an average failure time of 1 million hours and can withstand 1500G impact. Size 100.2 × 70.0 × 9.8 mm, weighing about 80 grams. Compared with SATA interface SSDs, it has significant advantages!
