<h1 class="pgc-h-arrow-right" data-track="1" > [pit black group].</h1>
First of all, let's talk about the two or three things that I entered the pit black group, everything seems to be a coincidence, because a certain degree of network disk is always inexplicably blocking my resources, so I came up with the idea of a private cloud, just happened to see the tweets of various big guys in ZDM, especially the "picking up garbage" sharing of the Arvinia gangster, seeing the family video center, personal website, private library, remote hang-up download and other functions, the small heart palpitation is unbearable, in 2020 618, I chopped my hands to form a black group.
However, the game between productivity and iQiyi has basically not stopped during the year, except for the occasional backup of Baidu cloud disks, the black group has not brought any changes to my life. For an ordinary user, all the fantastic functions are broken by tedious operations, the black group may be very powerful, but as a social animal that works overtime like eating, there is not so much time to toss, and several functions that are difficult to study are still not learned by the family (mainly the Queen Lord... All kinds of spit. Therefore, taking advantage of this wave of hardware price increases, I retreated.
PS: There is no meaning to belittle the black group, but I just want to say that for the small partners who do not like to toss, the black group is not the best choice.
<h1 class="pgc-h-arrow-right" data-track="5" > [into a hard disk cabinet].</h1>
So where does the data go from here? How can I solve the problem of daily backup storage? In fact, think about it, my requirements for storage are relatively simple, storage is the first requirement, and then it is possible to bring a little mobile phone backup, taking into account the download is also good, of course, it is best to be unlimited speed. seem...... Suddenly glanced at the player cloud that had been idle for a long time, and suddenly had a thought, as a large-capacity storage, the neutered old hen + hard disk cabinet is more suitable for me. So I started the more affordable Orecco NS200C3, with two plates.
Orec NS200C3 is not small, filled with a large amount of cushioning foam, all aluminum alloy body.
To tell the truth, ORICO is also a more familiar brand, better than the price is cheap. This NS200C3 should be regarded as a product with excellent industrial design in their home. The use of 4mm thick all-aluminum alloy integrated body coverage, texture and heat dissipation is better, the side is a large LOGO, simple and beautiful.
The third digit of the NS200C3 represents the plate position, and I chose the double plate position. The design of the large-area honeycomb heat dissipation hole at the tail effectively improves the heat dissipation performance, in addition to the power switch, data interface and power interface, built-in 40mm double ball bearing fan, high speed, large air volume. There is no RAID function, mainly consider buying double disk bits, RAID function is indeed dispensable, it is better to pursue a price-performance ratio.
The front panel is a magnetic design that can be suspended in mid-air, which is not very interesting.
However, the panel is ABS material, which is more likely to produce scratches and fingerprints, and is surrounded by a circle of heat dissipation holes. It was chosen mainly because it is more convenient to use without tools.
Two flap doors, the location of the connector insertion has been marked on the door, as long as the hard disk is aligned and inserted.
Speaking of capacity, Oreo's NS200C3 supports a total of 28TB large capacity, single disk support 14TB, but now this hard disk price, 14T is also too luxurious, I chose two Toshiba NAS hard disk N300 series 6T hard disk.
It was chosen because this is Toshiba designed for NAS systems, and because it is considered to be used in NAS scenarios, it is preferred for NAS dedicated disks. Compared to desktop hard drives, it supports 7×24 power-on uninterrupted operation. At the same time, the NAS hard disk stability will be stronger, and the noise will be lower, quieter.
Toshiba's hard drive uses a SATA3.0 6Gbps speed interface, 7200RPM speed, and 256M independent cache. Its size is 147mm× 101.85mm×26.1mm, the length and width are standard 3.5 inches, the hard disk weight of about 700 grams, the weight is full. As a NAS hard disk, The speed of Toshiba N300 series hard disk is also excellent, the previous NAS hard disk often has a relatively low speed, and Toshiba's hard disk meets the premise of stability, and the motor speed is the same as that of ordinary hard disks, reaching 7200RPM.
The label on the front indicates that the origin is the Philippines.
The trapezoidal PCB board can be seen that Toshiba's workmanship is still very delicate, and has a built-in rotational vibration (RV) sensor.
Stability is very important for NAS. Toshiba N300 Series hard drives provide 1 million hours of MTTF, and vibration compensation technology is also used to help provide consistent performance in multi-disk storage cabinets. After all, hard drives have a price, data is priceless, and a safe and reliable hard drive is more important than all expenses.
In addition, why choose Toshiba N300, but also because this series of hard disks fully use CMR technology. Hard disks using CMR technology have space between tracks, and data will not be stacked, which is suitable for system disks or hard disks that need to be read and written frequently. At the same time, hard disks with CMR technology have a longer service life and better read and write performance, especially write speeds. In addition, the security aspect is also more secure, and it is easier to recover data even in the event of unexpected situations. At least personally, NAS still prefers to use CMR technology for hard drives.
OK, install the hard disk, plug in the power supply, and you are ready to test. The external 12V4A high-power power supply is powered, and the workmanship and material are good.
<h1 class="pgc-h-arrow-right" data-track="21" > Performance and Expansion</h1>
First do the performance test, Orecco NS200C3 uses the JMS561U+ ASM1542 master control scheme, support UASP acceleration protocol; because there is no RAID function, so there is no speed bonus of course, there is no data recovery function, the hard disk cabinet is only used as a large-capacity hard disk enclosure, and 2 6T hard disks are identified separately.
First format the hard disk to detect the health of the hard disk. One word, "steady"!
First of all, the HD Tune Pro hard disk performance diagnostic test tool is used to test the underlying read and write performance of the hard disk, the so-called underlying test is to test the original read and write performance of the hard disk without partitioning. In fact, there are many functions of this software, it can detect the hard disk transfer rate, burst data transfer rate, data access time, CPU usage, health status, temperature and scan the disk surface.
From the HD Tune test, the average reading speed reached 188.1MB/s; the maximum reading speed reached 230.4MB/s. In terms of write speed, the average write speed reached 175.8MB/s; the maximum write speed reached 222MB/s. The read seek time is 13.2 milliseconds and the write seek time is 4.54 milliseconds.
CrystalDiskMark's read and write test made me a little surprised, the sequential read and write speed actually reached nearly 200MB/s, and more unexpectedly, the lightning port of NUC8 with C TO C can actually press to 250MB/s, and the theoretical speed is still very good.
For this reason, I also checked the speed of the hard disk, which is basically the limit of this HDD. So what was the actual experience? Direct copy of a single large file, the transfer speed of the write is almost 150MB/s, and the read reaches 200MB/s.
If it is a copy of a large number of small files, the speed will be slightly reduced, basically around 100MB/S. In addition, considering that the hard disk cabinet needs to be used for a long time, Orec also provides automatic hibernation function, which will undoubtedly reduce the power consumption of the hard disk cabinet.
<h1 class="pgc-h-arrow-right" data-track="29" ></h1>
At the end of the article, I still want to say that friends who have time to toss and study self-organized black groups are definitely the best choice, because it can bring maximum performance. As for brands such as Synology and Wei Unicom, in addition to being a little expensive, other aspects will be more secure. But ordinary individual users or home users, if there is not so much high-end demand, worry and effort to save power while also solving the problem of file storage space and security, then in fact, play Keyun or Hikvision H series personal cloud storage with a hard disk box is enough. Routers with USB interfaces that have been popular for a while can actually be used as cloud disks, so it is recommended that you choose rationally according to your own situation.
The last little suggestion: the hard disk selection is recommended in one step, the hard disk is valuable, the data is priceless, and big brands such as Toshiba and Western Digital have hard disks specifically launched for NAS, especially Toshiba's vertical disk, which should be the hot choice in the past two years. Of course, everything is better to buy after the tide of mines has passed, and the price is rational.
