As the quality of multimedia files improves, the file capacity will naturally increase. Therefore, for NAS users who have a lot of multimedia storage needs, the larger the hard disk capacity specification of the machine, the better. So this time, I also borrowed three 8TB hard drives for NAS, including Seagate NAS HDD (IronWolf), Seagate Enterprise NAS HDD (IronWolf Pro), and WD Red Red Label series, to test it out, so that netizens can choose large-capacity hard drives. It can be used as a reference when matching NAS devices.

●Seagate NAS HDD (IronWolf) 8TB hard drive specification introduction

Seagate's NAS HDD series (recently officially renamed IronWolf) for 1~8Bay NAS devices is different from general desktop hard drives in that there are more ADC1005BCJ-1 rotational vibration sensors, dual balance motors and Designs such as error recovery control allow the hard drive to operate continuously and stably in a 7x24 working environment, and can achieve an annual data transfer volume of 180TB.

At present, the capacity of this series of hard drives can reach up to 10TB, and the 8TB NAS HDD tested this time is equipped with a total of 6 storage discs, the speed specification can reach 7200 rpm, and the maximum transfer speed can reach 216MB/s.

The detailed model of the NAS HDD 8TB hard drive tested this time is ST8000VN0002, and the origin is Thailand.

The hard disk transmission interface adopts SATA 6Gb/s.

After removing the circuit board, you can see that the main control chip has a thermal conductive patch, and there is a built-in 256MB model from Samsung.">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 DDR3-1600 memory particles are used as cache space, detailed model K4B2G1646Q-BCK0.

The main control chip mounted on the hard disk circuit board is Seagate's own LSI TTB71001V0 chip.

There is also a SMOOTH hard drive motor driver chip on the circuit board.

In addition, the Seagate NAS HDD has a rotational vibration sensor added to the circuit board of the 6TB, 8TB and 10TB capacity versions, which can reduce data reading errors caused by the vibration of multiple hard drives.

The actual weight of the hard drive is about 773 grams.

●Seagate Enterprise NAS HDD (IronWolf Pro) 8TB Hard Drive Specifications

Seagate has also launched another Enterprise NAS HDD series (recently renamed IronWolf Pro) for NAS devices, which are mainly designed for 1~16Bay professional or enterprise NAS devices. The difference between this series of hard drives and the NAS HDDs introduced above is that in terms of durability design, it can reach 300TB of data transmission per year, and the warranty period is increased to 5 years, and it will provide a free two years before the warranty period. Seagate Rescue Data Recovery data recovery service (registration required) provides additional protection for user data. This series of hard drives will be available in 6TB, 8TB and 10TB capacity versions, and all have support for rotational vibration sensors, dual-balanced motors, and error recovery controls.

The Seagate Enterprise NAS HDD tested this time has a capacity specification of 8TB, which is equipped with a total of 6 storage discs and 256MB memory particles as a cache. The speed specification is 7200 rpm, and the maximum transfer speed can reach 230MB /s.

The detailed model of the hard drive tested this time is ST8000NE0001, and the origin is also in Thailand.

Seagate Enterprise NAS HDD series hard drives also use SATA 6Gb/s transmission interface.

The main control chips on the circuit board are equipped with thermal conductive patches, and next to the main control chip, you can also see that the built-in 256MB memory particles are DDR3-1600 memory particles introduced by Samsung, and the detailed specification is K4B2G1646Q-BCK0.

The main control chip of the hard disk also adopts Seagate's own LSI TTB71001V0 chip.

The circuit board is also equipped with a SMOOTH hard disk motor driver chip.

Seagate Enterprise NAS HDD series hard drives are also equipped with rotational vibration sensors on the circuit boards, making it more stable when multiple hard drives operate at the same time.

The actual weight of the hard drive is about 774 grams.

● WD Red 8TB hard drive specification introduction

WD has always used color to distinguish its hard drive product series, and the Red Red Label series is a hard drive product specially designed for NAS devices, and it has also launched Red and Red Pro for devices with different numbers of hard drives. Two red label series products. The difference between these two series of hard drives and other WD green label, blue label or black label hard drives for desktop computers is not only lower operating power consumption, but also adding RAID application optimization and vibration balancing technology to make the hard drives Able to achieve 7x24 long-term stable operation. The Red series in the WD Red Label series is a hard drive product designed for NAS devices with 1~8Bay specifications. There are 1~8TB capacity specifications to choose from, and the hard disk speed specifications are designed to be 5400 rpm, and all are provided Three-year warranty service. The other Red Pro series is designed for NAS models with 1~16Bay specifications. In addition to the speed specification being increased to 7200 rpm, the warranty service period has also been increased to 5 years.

The WD Red series will have versions with 1TB~8TB capacity specifications. The 8TB version is specially equipped with helium filling technology, and is equipped with 7 storage discs and 128MB cache memory. The speed specification is 5400 rpm. The maximum transfer speed can reach 178MB/s.

The WD 8TB Red Red-labeled hard drive model is WD80EFZX, which is produced in Thailand, and will be pre-loaded with NASware version 3.0 firmware when it ships.

WD Red series hard drives also use SATA 6Gb/s transmission interface.

After removing the circuit board, you can see that a piece of insulating foam is added between the hard disk and the circuit board, and a thermal patch is set on the main control chip.

The signal contacts on the hard disk are designed with retractable pins.

A 7101B hard disk main control chip launched by LSI is mounted on the circuit board of the WD Red 8TB hard disk.

Next to the control chip is a Samsung DDR3-1600 memory particle with a capacity of 128MB, which is also used as a cache space. The detailed model is K4B1G1646G-BCK0.

The hard disk is also equipped with a SMOOTH L7229 hard disk motor driver chip.

WD's 8TB Red hard drive circuit board also has a rotational vibration sensor, which enables more stable transmission performance when multiple hard drives are operating at the same time.

The actual weight measurement shows that although the WD Red 8TB hard drive is a 7-disc design, it is more than 100 grams lighter than the Seagate 6-disc product due to the introduction of helium filling technology to make the internal structure lighter.

●Measurement of hard disk performance

After reading the specifications of the three hard drives, let's actually test the performance! This time, in addition to testing the performance of a single hard drive with a desktop computer, we will also actually install a NAS and configure the access performance of a RAID 1 disk array. The NAS model used this time is the DS716+ from Synology with two RJ-45 network ports. Therefore, when connecting to the NAS for testing, two computers will be used to read or write data through the network ports at the same time. The list below is the test platform components, for your reference.

●Trial summary

The two Seagate NAS series hard drives use 7200 RPM and 256MB of cache memory. The read and write performance of a single drive can reach about 240MB/s, and the access performance with NAS can also reach about 180~190MB/s. , Write about 160~170MB/s, the performance is not bad. Therefore, if you pay more attention to the CP value, the NAS HDD series in the two NAS series, which is the current IronWolf series, will be a good choice, but if you pay more attention to the warranty period or need data rescue services, the IronWolf Pro series has a five-year warranty. And the free data rescue service every two years is quite attractive, but the price is naturally higher.

WD Red series hard drives may be due to the consideration of power consumption and temperature, the speed specification is only set at 5400 rpm, so the read and write performance of a single drive is about 185MB/s, and the access performance with NAS is about as high as read and write. 185MB/s, write about 140MB/s. Therefore, if you are more demanding on performance, it may be more suitable to match the Red Pro series with a speed of 7200 rpm, and the warranty period is also longer.
