The Desktop HDD series hard drives launched by Seagate for the desktop computer platform have been stuck at the 6TB stage for some time, and recently they have finally launched 8TB hard drive products with larger capacity specifications. Seagate's new Desktop HDD 8TB hard drive is the same as the previous Desktop HDD 6TB hard drive, which uses a six-disc design, but a special point is that the magnetic density specifications of each disc in the 8TB hard drive have been improved. to 1.33TB, so the storage capacity of the hard disk becomes 8TB. Moreover, the 8TB hard drive launched this time is also designed with a speed specification of 7200 rpm, and the increase in magnetic density also makes the transmission performance of this hard drive better.

●Seagate Desktop HDD unpacking and specification introduction

The Seagate 8TB Desktop hard drive tested this time is shipped by the international agent of Jianda, and there is also a special mark on the outer box, and a three-year warranty service will be provided for this hard drive.

On the back of the outer box are some warranty terms and information such as service calls.

There is also an extra layer of crash box in the package to protect the hard drive to reduce the risk of damage due to shipping.

Recently, Seagate's 3.5-inch hard drive products for desktop computers seem to have not used Baracuda as the hard drive name, but directly called Desktop HDD. I believe this naming method should also be used to allow users to distinguish more intuitively. Use Seagate's different series of hard drives!

As can be seen from the sticker on the hard drive, the detailed model of this 8TB Desktop HDD hard drive is ST8000DM002, the Date Code is 16222, the actual date of conversion should be November 27, 2015, and the manufacturing location is in Thailand. However, this time, the hard disk capacity is not directly marked on the hard disk as before, but can only be known from the model.

Seagate's newly launched Desktop HDD 8TB hard drive still adopts PMR (Perpendicular Magnetic Recording) technology. In the hard drive, a total of six disks are installed, each with a capacity of 1.33TB, and there are also 12 hard disk heads, the speed specification can reach 7200 rpm.

The transmission interface of this hard drive also uses SATA 6Gb/s.

Remove the four screws on the motherboard behind the hard drive to remove the hard drive motherboard. In addition to adding insulating spacers on the motherboard, some main AD9983AKCPZ-170 models "> AD9983AKCPZ-170 models "> AD9983AKCPZ-170 models "> AD9983AKCPZ-170 models "> AD9983AKCPZ-170 models are also added on the chip. Put on the thermal pad to increase the heat dissipation effect.

The main control chip of this hard disk is the TTB71001V0 model launched by LSI">TTB71001V0 model">TTB71001V0 model">TTB71001V0 model">TTB71001V0.

There is also a DDR3L cache memory chip launched by Micron on the hard disk motherboard, the capacity specification is 256MB, and the detailed model is D9PTK.

The Desktop HDD 8TB hard drive motherboard launched by Seagate this time is also equipped with a SMOOTH chip to drive the disk motor.

The actual weight of this hard drive is about 768 grams.

●Seagate Desktop HDD performance test

This hard drive is not initialized when it is shipped, so before testing, it is necessary to select the hard drive as the GPT partition style and format it as a single hard drive volume for performance testing.

After formatting, you can see from the file manager that the hard drive has a usable capacity of about 7.27TB.

As can be seen from the CrystalDiskInfo software, the rotational speed specification of Seagate's Desktop HDD 8TB hard drive is 7200 rpm, and the pre-loaded firmware version is DN01 model > DN01 model > DN01 model > DN01 model > DN01.

Before the test, I will attach a list of the platform components for this match for your reference.

◆Anvil's Storage Utilities software test

When testing this hard drive with Anvil's Storage Utilities software, the sequential read and write performances were 234MB/s and 206.74MB/s, respectively, and the 4K read and write performances were 0.89MB/s read and 2.7MB/s written, respectively. The score was 524.33 points.

◆ATTO Disk Benchmark software test

In the test of ATTO software, when the test file length is 8MB, the read and write performance of Seagate's Desktop HDD 8TB can reach about 251MB/s and 250MB/s.

◆CrystalDiskMark software test

When the test data is the default random number, the read and write performance in the sequential read project of this hard drive are 248.5MB/s and 233MB/s respectively; the read and write performance in the 4K project 0.932MB/s and 2.926MB/s respectively.

When the test data is set to 0Fill 10, the read and write performance of this hard drive in the sequential read project are 250MB/s and 237.2MB/s respectively; the read and write performance in the 4K project are 0.923MB respectively /s and 2.9MB/s.

◆PCMark 8 software performance test

After testing the storage items of PCMark 8 software, the test result of this hard drive is 3305 points, and the transmission bandwidth is 19.02MB/s.

◆Operating temperature test

When the hard disk is used continuously for about 5 hours in a bare metal state, the operating temperature will reach about 50°C.

●Test summary

From the perspective of performance, Seagate's Desktop HDD 8TB hard drive for desktop computers this time has not only increased the capacity specification through the improvement of magnetic density, but also the actual test reading and performance can reach about 250MB/s. As far as the magnetic recording hard disk product is concerned, the performance performance is indeed quite dazzling. At present, the suggested price of this 8TB is about NT$12,000. Although the price of a single hard drive is higher, it is actually similar to two 4TB or four 2TB 3.5-inch hard drives. For those who need large-capacity storage In other words, the larger the capacity of a single hard drive is, the less hard drives are required, which in turn reduces the power consumption and heat generation of the computer. However, although large-capacity hard drives have more storage space utilization, when all data are placed on the same hard drive, the risk is relatively increased. If one day 8TB of data is completely destroyed, it is really not a human tragedy. So it is recommended that users use some backup solutions to be more at ease!
