Description
Dateks offers to buy the Seagate hard disc with 20 TB data capacity, SATA III connection, 7200 rpm rotation speed and 256 MB cache memory.

This hard disc has SATAIII connection. SATAIII, or SATA 6GB/s is the latest generation data transmission connection found in the most modern computers for ensuring sufficient SSD discs data flow exceeding the SATAII possibilities. The speed of the cache memory of hard discs can sometimes exceed also the SATAII passage possibilities because in essence this cache memory is a small size SDD disc (~64 Mb). Therefore, when the relevant port is available on the motherboard it is advisable to select the SATAIII disc.

Thanks to the 7200 rpm rotation speed of magnetic discs this hard disc provides the optimum fast operation in the data search and transmission. 7200 rpm is the classic standard for the universal application both for the maintenance of the operating system and applications and the data archiving.
All parameters
Capacity 20 TB
The HDD capacity in Gigabytes indicates how much information can be stored by the HDD. The capacity of the HDD is fixed and cannot be increased after buying the HDD. Therefore, upon buying the HDD you should verify its compliance with your current volume requirements and provides a reserve for future needs.
Use : NAS
Data Interface SATA III
The connection of the HDD to the computer. The current industry standard is SATA connection. IDE connection is available with older computers. Prior to buying the HDD you should verify whether the motherboard has a free connection slot and the support for the chosen disc capacity.
Spindle rotation speed 7200 rpm
The HDD rotations. The HDDs of most desktop computers have 7200rpm and this has already become the industry standard. If you want to achieve a higher speed you should buy the HDD of 10000rpm. The operation noise, temperature and power consumption of 10000rpm HDDs are much higher than these of the 7200rpm HDDs parameters, therefore, prior to buying a 10000rpm HDD you should verify the compliance of the enclosure, power supply unit and the cooling with the technical requirements of this HDD.
Data buffer 256 MB
Data buffer is a high-speed memory built-in the HDD and allowing the disc to receive data at a smooth speed irrespective of the level of loading the physical memory of the disc at the particular time. If you work with a high number of small volume files (documents, photos, etc.) we recommend to buy an HDD with 8Mb or higher data buffer.
