At present, the main storage carrier of NAS still relies on HDD mechanical hard disk, mainly mechanical hard disk can take into account the characteristics of large capacity and low cost file storage, coupled with the limited bay of the mainstream NAS system now, to meet the user's cloud storage application needs, it is necessary to have a single disk large capacity and NAS hard disk with professional safety technical support.
As a traditional storage brand, Seagate also has its own series of NAS hard drives for different application needs of nas platforms, such as the Coyote for mainstream NAS and the Coyote Pro for high-end personal/small studio/enterprise NAS. Recently, the evaluation room received a new product from Seagate's Coyote Pro series, a 20TB Coyote Pro 20TB NAS hard drive with a capacity of 20TB.
Seagate Coyote Pro 20TBNAS HDD features
The Coyote Pro Series is a NAS-optimized AgileArray hard drive product for 24X7 use, optimized specifically for nas, supporting dual-plane balancing and time-limited failure recovery, especially in multi-bay systems to provide excellent RAID performance. ，
The Seagate Coyote Pro 20TB is the same as the 18TB version in terms of reliability, and can also meet the workload of 300TB per year and the MTBF mean failure interval of 1.2 million hours.
At the same time, the hard disk adopts a built-in rotation vibration sensor, which can detect the overall health of the hard disk, especially in the multi-bay hard disk box or NAS system, which can maintain long-term stable operation. And the hard disk is also equipped with AgileArray technology, providing better power management, can achieve double-sided balance and RAID optimization in multi-bay environment, and ensure the reliability and scalability of the entire hard disk architecture.
In addition, Seagate also provides dedicated IHM Seagate Coyote health management software for the Coyote Pro series hard disk, which can actively monitor the operating environment, find potential problems, and call adaptive algorithms to manage the performance parameters related to the hard disk, and warn in advance before the hard disk has problems, which shows that it has a good foundation in the use of safety performance.
The Seagate Coyote Pro 20TB hard drive is out of the box
The Seagate Coyote Pro 20TB is currently the largest product in the Seagate Coyote Pro series, with a model name of ST20000NE000, a hard drive speed of 7200 rpm, a cache of 256MB, and a 5-year warranty.
The appearance of the Seagate Coyote Pro 20TB hard drive is a metallic silver top cover and a matte black bottom cover, the size and size is about 26.11 mm x 101.85 mm x 146.99 mm, which is not very different from the general mechanical hard disk, but this small volume is placed in up to 10 pieces of storage discs, which is also the industry's first 10-disc packaging process owned by Seagate, coupled with the use of CMR traditional magnetic recording technology. Ensure that the hard disk read and write performance of multi-disc stacking can also have efficient performance.
The Seagate Coyote Pro 20TB hard drive weighs around 681.3g, which is quite a textured presence in the hand, and the hard disk is designed with 10 discs built in, which is not surprising to achieve this weight.
The hard disk is covered with the product specification label, the label is printed with the detailed graphic LOGO and English brand name on the white characters on a green background, of course, there is also the Wolf Graphic LOGO and text label, of course, the word "NAS" is marked in the form of black characters on a red background, highlighting that this is a hard disk product designed for nas platforms.
The motherboard part of the hard disk is located at the end of the bottom cover, due to the high degree of integration of the circuit, the size of the entire hard disk motherboard is quite small, and the interface between the hard disk and the platform adopts the conventional SATA 3.0 interface design, which has quite excellent versatility, which can not only be applied to most of the current NAS platforms, but also can be used on desktop platforms.
The hard disk motherboard is fixed to the hard disk bottom shell by 6 fixing screws in a reverse-mounting manner, and the control components inside the hard disk are connected by wire pin contact, while the important control chips and other functional components on the motherboard are located in the bottom shell due to the reverse installation of the motherboard, which plays a better role in protection.
A Smooth Viking motor servo chip plus a Seagate 500051851 master driver control chip and a Samsung DDR3L cache chip numbered K4B2G1646F-BYMA are used on the motherboard.
Seagate Coyote Pro 20TB performance review
First, we first relied on the desktop computer platform to conduct a simple performance test of the Seagate Coyote Pro 20TB hard drive, and then combined with the NAS platform to see how it would perform on the NAS platform.
Using CrystalDiskInfo software to view the hard disk information, we see that the firmware version number of the Seagate Coyote Pro 20TB is EN01, the transmission mode is SATA/600, the ACS-4 standard is supported, the S.M.A.R.T, NCQ is supported, and the actual usable capacity of the hard disk is 18.1TB. The overall health of the drive as well as the specifications meet the product description.
Through DiskGenius, the hard disk is not formatted before detection, and the hard disk information similar to ThatstarDiskInfo can also be seen, except that DiskGenius will be more inclined to refine and standardize the data presentation.
