With the rapid popularization of mobile terminal devices and digital products and the continuous improvement of people's living standards, each person or family will have multiple computers, smart phones, tablet computers, and digital camera devices. The result is a large number of data files, including many data that require long-term preservation and multi-device sharing. Many people will suffer from a hard disk or memory card damage, leading to important work, learning documents and precious video, photo files completely lost painful experience.
 The thing that always thought that the camera card was burned was in the legend, but it never occurred to us that the tragedy came to a head. If you do not have the habit of backing up, you will eventually pay a heavy price. With painstaking experience, this was specifically equipped with a Tieweimar D4-310 DAS (direct-attached storage) device for data backup. The data is priceless and there are many precious records that are lost and cannot be found.
 Something was sent to the other, and two 2T red disks were returned as storage. . .
Product unpacking:
In addition to the D4-310 mainframe, the Tieweimar D4-310's packaging and internal products and accessories include a product manual, a warranty card, an external power adapter, a TYPE-C cable, and an installation gadget.
The product is designed with four 3.5-inch hard disk docks, supporting 8TB on a single disk, and a full capacity of 32TB.
In the material of the body shell, a thickened 2.5mm aluminum alloy shell is used, which is ideal in terms of firmness and heat dissipation.
The D4-310 uses a fan to actively dissipate heat. A double cooling fan can be seen behind the body. It can ensure long-term stable operation of the hard disk in the DAS. In addition, you can see the USB3.0 interface, TYPE-C interface, and RAID0/RAID1 mode conversion knobs on the side of the cooling fan. With the mode switch knob, the user can easily switch the memory mode.
The machine comes with two USB 3.0 expansion ports, this is not bad, for notebook users, after connecting can use this to expand, do not worry about the USB interface is not enough.
The bottom of the fuselage close-up. After all, when the four hard disks are fully installed, the heat dissipation requirements are still relatively high. The D4-310's dual active cooling fan and heat vent design ensures long-term, stable operation of the internal hard drives, while also ensuring the safety of important user data.
Product dismantling:
It was found that the machine was not screw-sealed, and it was easy to disassemble the shell and see the inside of the D4-310. The USB ports and knobs on the blue PCB below are the locations where the rear of the camera was seen.
Corresponding to the power supply and data interface board of the four hard disk installation positions, the surface of the chip controlled by the master for a long time has been polished, and the details are unknown.

State after installing the hard disk
Hard disk purchase and installation:
Next, install the hard disk, and further experience and testing of the use of the Temavio D4-310. Here are used two Western Digital 2TB hard drive, NAS dedicated red disk. Although the advantage in speed is not obvious, stability is notoriously good, and this is what I value most.
Users are very convenient when installing and removing hard disks. They can support both 2.5-inch SSDs and 3.5-inch mechanical hard disks. Four hard drive installations have a great advantage in terms of future capacity expansion.
Included power adapter, and TYPE-C data cable
One TYPE-C data line, using USB3.1gen-1 protocol for ultra high-speed data transmission interface, support positive and negative insertion
Read and write speed test: (Raid 0) high speed mode
Let's look at the performance of this DAS in actual use. The D4-310 is a DAS that can both take into account (Raid 0) high-speed mode and (Raid 1) security mode, and can support the combination of two or two hard disks for different disk array modes and arbitrary switching of four hard disk arrays. Hard disk 1 and hard disk 2 form a Raid 1 installation mode, and you can also use hard disk 3 and hard disk 4 to form Raid 0 high-speed mode.
First of all, we set up and test the Raid 0 high-speed mode of Tieweima D4-310. In Raid 0 high speed mode, two hard disk capacities can be fully utilized. Through the disk project information in the computer management, you can see the full capacity information of D4-310.
Raid 0 high-speed mode is a superposition of two hard disk capacities, the sum of two 2T capacities is 4T
Below we need to test the read and write speed of Raid 0 high-speed mode D4-310 through some disk testing tools. The first is the ATTO Disk Benchmark test. Through the test results, it can be seen that the read and write speed of the D4-310 performs very well in the Raid 0 high-speed mode.
What continues to be tested is the AS SSD Benchmark.
Followed by CrystalDiskMark test results. . .
In front of the benchmarks on the software, and then again the actual transmission of the file test, through the Windows file transfer monitoring map can be seen from the iron Weimar D4-310 copied to the desktop speed, followed by copying from the desktop back to D4-310 Screenshots.
Read and write speed test: (Raid 1) safe mode
There is also a 1TB green disk in the hand. Let's try the Raid 1 security mode for the two red disk groups, which are used for saving important data. Another green disk is used alone to download the entertainment game disk.
Install the third hard drive in.
In front of Raid 0 high-speed mode, the advantage is to get the maximum storage space and high-speed read and write storage. Next, switch to Raid 1 safe mode, RAID 1, which is the automatic backup mode, in which the effective use of the two hard drives becomes 50%. Before I installed two 2TB red disks with a total capacity of 4TB, in RAID1 mode. Among them, 2TB is used as storage, and 2TB is used as a backup for data. After double backup, even if a hard disk is completely damaged, it will not result in data loss. The benefit of Raid 1 security mode is double protection. Guarantee the absolute security of data.
After adjusting the Raid 1 security mode, the D4-310 was tested again using disk test tools such as AS SSD Benchmark, Crystal DiskMark, and ATTO Disk Benchmark.
In Raid 1 safe mode, the actual file copy speed test from desktop to DAS and DAS to desktop.
Game test:
The following is the final installation of the third 1TB Western Digital green disk used as a SINGLE mode alone, as an entertainment game hard disk direct loading game running test.
The speed of loading the game is basically the same as the local disk, loading the game and running the game is like the computer's local hard drive.
Toss about the same, this way, the level is limited, to share here
Advantages: Through the application of multiple modes in front, and behind the hybrid application, you can see that a machine of the Temamar D4-310 provides two array modes for the user, which is more practical. In use, the user can According to the different importance of data selection Raid 0 high-speed mode and Raid 1 security mode, can also be used in a mixture of two colleagues, different types of data storage, in the use of both high-speed storage and secure storage at the same time.
Improvement: Mode switching requires the use of tools to set up. It is estimated that the manufacturer's starting point is to worry about user misoperation. There is room for optimization here. Also equipped with a restart thimble is easily lost, Oh, I can not find it after using it once. . .
Having said so much is just trying to warn you about the importance of data security. This time it is an insurance policy for all kinds of data. It will no longer be afraid of accidents. . . Finally, I heard that the use of hybrid hard disk Raid 0 mode speed will be improved, I do not know if there are valued friends used, seeking recommendations, I really want to try fresh.
