With the improvement of image quality, the required file storage space naturally also increases, so in order to allow users to have more space for application, Seagate recently added its IronWolf series hard drive product line specially designed for 1~8Bay NAS models. A 3.5-inch hard drive with a capacity specification of up to 14TB was launched again. In addition to the increase in capacity, Seagate IronWolf 14TB hard drives have also introduced their own AgileArray technology, which not only enables the hard drives to optimize performance and data security in a RAID environment, but also has a dual-disk balancing function to avoid excessive The situation that the hard disk vibration affects data reading and writing occurs. According to official data, this hard disk can reach 1 million hours of MTBF and 180TB annual write capacity specifications, and also provides a 3-year warranty service.

In addition, Seagate specially provides IronWolf Health Management for IronWolf and IronWolf Pro series hard drives. As long as it is paired with devices from three NAS manufacturers, Asustor, Synology and Thecus, the IHM function can be enabled in the system, allowing users to more quickly View information such as hard disk operation status and detection health.

●Seagate IronWolf 14TB Hard Drive Unpacking and Specifications

The detailed model of Seagate's new 14TB IronWolf hard drive is ST14000VN0008, which is equipped with a total of 8 discs and 16 sets of read-write heads, and still uses the traditional CMR magnetic recording technology to make the hard drive reach 14TB capacity specifications, and it is also Helium filling technology is used to reduce air resistance, thereby achieving the effect of cooling and saving electricity. In addition, it can be seen from the sticker on the hard drive that the 14TB Seagate IronWolf hard drive is also made in Thailand.

Seagate IronWolf hard drives are mainly designed for 1~8Bay NAS devices. Compared with ordinary hard drives, the differences between the hard drives themselves are that the hard drive mechanism adopts 7X24 operation design. In addition, there are more rotational vibration sensing and dual-disc balance technology, which can reduce the vibration caused by the rotation of the hard disk itself or the operation of multiple hard disks for data access images.

The 14TB Seagate IronWolf hard drive is also designed with helium-filled technology, and is sealed with all-aluminum welding to avoid helium leakage.

The Seagate IronWolf 14TB hard drive also adopts the SATA 6Gb/s transmission interface specification.

Then remove the hard disk circuit board to see the circuit specifications of this hard disk.

The main control chip on the circuit board of the Seagate IronWolf 14TB hard disk adopts the Marvell i1261-B1 control chip, and there is a model D9PTK with a capacity specification of 256MB next to it. > 256MB model > 256MB model > 256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model">256MB Model” >256MB model > 256MB model > 256MB of Micron Micron DDR3L-1600 memory chips as cache space.

There is also a SMOOTH operating motor control chip on the circuit board.

There are ADS1282IPWR rotary vibration sensors installed in the corners of both sides of the circuit.

●Seagate IronWolf 14TB hard drive performance test

After briefly reading the unpacking and specification introduction of Seagate's 14TB IronWolf hard drive, let's take a look at the transmission performance of the hard drive! The following is a list of components used in the test for your reference.

◎Processor: Intel Core i7-8700K

◎Motherboard: ASUS ROG STRIX Z370-F GAMING

◎Memory: G.Skill TRIDENT Z RGB DDR4-3200 8GBx4

◎ Hard drive: WD Black NVMe 1TB SSD solid state drive

◎Operating system: Windows 10 64 bit

After actually installing the computer and formatting, you can see through the file manager that the 14TB Seagate IronWolf hard drive has a usable capacity of about 12.7TB after formatting.

Through the CrystalDiskInfo software information, we can see that the speed specification of the Seagate IronWolf 14TB hard drive is 7200RPM, and it is equipped with SC60 version firmware. The detailed model is ST14000VN008-2J101.

●ATTO Benchmak test

When actually using the ATTO software to test, the read and write performance of the Seagate IronWolf 14TB hard drive can reach about 260MB/s after the file length is 8KB.

●CrystalDiskMark test

When the CrystalDiskMark software is set to the random data option, the read and write performance of the Seagate IronWolf 14TB hard drive in sequential read and write projects can reach approximately 269.3MB/s and 263.9MB/s, while the read and write performance in 4K projects can reach approximately 0.9 MB/s vs 1.6MB/s. When the data option is set to 0Fill mode, the read and write performance of the Seagate IronWolf 14TB hard drive in sequential read and write projects can reach approximately 269MB/s and 263.1MB/s, and the read and write performance in 4K projects can reach approximately 0.9MB/ s with 1.8MB/s.

●TxBENCH software test

When actually using the TxBENCH software to test, the read and write performance of the Seagate IronWolf 14TB hard drive in the sequential read and write QD32 project can reach approximately 261.102MB/s and 260.773MB/s, and the read and write performance in the random 4K QD1 project can reach approximately 1.095MB/ s with 2.04MB/s.

●NAS RAID0 performance software test

Since it is a product specially designed for NAS, this time I also borrowed two Seagate IronWolf 14TB hard drives and ASUSTOR AS4004T with a built-in 10Gb network port to test it together. In this test, two hard drives are set to RAID 0 mode, and a compressed file with a file size of about 5.8GB is directly transferred to the computer with an ASUS XG-C100C 10Gb network card.

When actually transferring from the computer to the NAS, the speed of writing to the NAS can reach about 308.3MB/s, and the actual transfer time is about 19.3 seconds. Then, when the same file is transferred from the NAS to the computer, the read performance from the NAS can reach about 422.2MB/s, and the transfer time is about 14.1 seconds.

●Test summary

After the actual test of the Seagate IronWolf 14TB hard drive, its performance is basically the same as the previous 12TB version. The maximum speed can reach 260MB/s, and the capacity is 2TB more. For NAS users who need large-capacity storage It can be regarded as an option with a larger capacity specification, but the current official suggested price of this hard drive is about NT$17,999, which is about 4,000 yuan more than the price of the 12TB version, although the capacity is larger, But there is still a big price difference, it depends on whether the user has a large-capacity demand!
