Secret Beyond Technology Solid State Hybrid Drives

In today’s world speeding paced, high speed is sought and coveted. The need for high speed is the reason for the increased use of Solid State Drives (SSD) in the computer industry.

SSD technology is capable of delivering speeds better data access using NAND flash memory. Although the adoption rate increased SSD, Hard Disk Drives (HDD) is still very competitive in the traditional storage media market, because the HDD is able to offer a far greater capacity to lower costs for consumers and OEM manufacturers.

With the emergence of Solid State Hybrid Drives (SSHD), computer users and OEM manufacturers can gain the advantages of HDD and SSD technology in one device.

SSHD is able to combine the advantages of the two ‘camps’ is because it uses advanced algorithms for optimal benefit from the HDD and SSD technology.

without limits

SSD and HDD technology each has its own advantages. The initial idea of technological innovation SSHD is: create a device that is able to combine the advantages of both technologies.

As the technology has begun to commonly applied in computer, SSDs use NAND type flash memory are susceptible to wear caused by read-write cycles.

While the HDD device, the cycle can be carried out up to thousands of times without risk of wear. NAND flash can only last about 10,000 to 60,000 times the board, depending on the type of flash memory used.

The problem of wear on the SSD to be a problem in the long-term durability and integrity of the data, especially for businesses users.

The problem is during the activity, those who have a laptop with SSD unconsciously do things that can mempendek their SSD lifespan, among others, write and erase data repeatedly, for example when creating and revising the document.

On the other hand there is the HDD. Mechanical components in the HDD is also often associated with the wear of the device along with the length of time of use, and relatively more susceptible to damage related to the rise and fall of voltage / electric current when compared to SSD.

Bearing / shaft of the hard disk drive will work constantly as long as the motor spins the hard drive, even in idle condition. In addition, the touch contact between the actuator head and disk media during the process of reading the data can also be the cause of the wear of the device.

So, how does the SSHD (eg: Seagate SSHD) achieve maximum performance and durability of these two technologies? Adaptive Memory technology is the answer.

To maximize the efficient use of storage technology on flash memory and HDD SSHD their products, Seagate developed a set of algorithms that can track data usage, and intelligently analyze the data which should be stored in flash memory and which are stored on disk.

This algorithm will also continue to make changes to the allocation of data in accordance with changes in data access patterns of the user.

Combining media HDD and NAND flash memory capacity is small (which has Adaptive Memory technology into a single device, SSHD offer synergies of both the storage media technology.

SSHD overcome the weaknesses of both technologies contained in these technologies with emphasis on the process of writing data using the HDD and the process of reading data using NAND flash.

By directing the majority of the process of writing data to the HDD in the device, limiting the SSHD process of writing data to the NAND flash memory, so it can extend the life of solid state components and enhance durability.

Using a similar principle, the process of reading data using NAND flash in the SSHD will make the HDD spins less, thereby reducing the risk of wear on the mechanical parts in it and touch minimize contact between head / disk media in the drive.

Durability Media Storage

Because NAND flash and HDD media complement each other in this device, Seagate hopes that the SSHD will surpass SSD and HDD in terms of durability. This expectation is also supported by data obtained from the field.

The chart below displays the field data obtained from one of the partners Seagate customer, a manufacturer of laptops with different segmentation classes. The information below shows the levels of returns (returns due to damage or the like) cumulative average in the period of 6 months.

As has been evidenced in the data, products Seagate second-generation SSHD (SSHD P2) reaches the level of the lowest returns of all laptop products purchased by consumers.

The data also showed that the SSHD product has endurance level higher than the HDD, the HDD P2 which became the basis of architectural design.


Now never bother to choose between speed SSD or HDD capacity. SSHD solution combines the best features of both technologies, creating a synergy that is ideal for performance, capacity, and reliability.

With intelligent algorithms to analyze and redirect the data, the SSHD utilize NAND flash memory and hard drive media optimally to cope with the workload of today’s computers. In the world of computer storage media, SSHD lets users get all the benefits in one solution.
