| When it comes to group disk array, in fact, the audience is really quite small, but mainly HDD, like our evaluation room just evaluated Orrick hard disk box, because the volume is too large are not called the hard disk box, called the ' Hard drive cabinet ', and this time, we get the small size of the Maiwo hard disk box, from the appearance point of view, this is the real' hard disk box '.  Maiwo K25272 hard disk box E-commerce price Loading... Hard disk box so small, will not fly? Believe it is most people who saw this box first feeling. Because the traditional group RAID disk array box size is still relatively large, this type of Small hard disk box seems to occupy the less mainstream status, as for the actual performance, take a look at it. Appearance: a little smaller than the phone In accordance with the usual practice from the packaging to see it, the entire packaging is smaller than the phone box on the back to write a very detailed product introduction, there are instructions in English, international can do it.  The back of the more prominent position to write support for HDD and SSD dual hard disk bits, support SATA interface 2.5-inch small SSD and HDD.  As usual, Zhang family portrait, reasonable, this small box to put things pretty much: hard disk box, power cord, Type-C data cable, two screwdrivers, a small hard disk base, screws and instructions, sparrow is small, It's  Hard disk surface is black anodized aluminum alloy material, coupled with the CNC cutting highlight transitional trimming, we are very familiar with, not to say.  The structure of the hard disk box is the plastic inner shell of the metal shell and the inner PCB board. The pull-out method can be extracted out of the whole to conveniently put the 2.5-inch hard disk.  Next, take a look at the details of the big picture, feel. Plastic inner shell has a DC charging port, Type-C interface, hard RAID switch, RESET reset button. Maiwo this hard disk box with a DC independent power supply port, -C interface power supply, wire a little more uncomfortable, but the power supply can be guaranteed. Hard RAID switch is relatively simple and clear, a look to know how to dial, just need to turn the switch up and down, you can set up RAID 0, RAID 1, JBOD these three modes, not through the software is also a great convenience.  The other side of the inner shell is a mesh-like cooling holes, and in general the cooling performance is sufficient.  Metal shell on it, but also on both sides of the hole, one side is the hard disk lights, enlarge the small details on the hole also used two CNC, small details in place; the other side is a fixed screw hole, the details are done Curved inward transition, work can be.   With the 2.5-inch hard drive with the basic is this state, the length of a 5.5-inch phone is also shorter than the point.  In addition, taking into account the limited desktop space characteristics, Mai Wo also die-like with a small base, the plastic material is very light, but the card is tight enough to put on the table there is a mold.  Brief summary , The appearance of some of the sum up is smaller than the phone, easy to carry and extend to the notebook, although very light, but the quality of the metal shell is still possible. Performance Test: USB 3.1 is a bit faster than 3.0 This time we got Type-C interface USB 3.1 Gen2 version, while the version sold on Jingdong is USB3.0 version, the bandwidth of USB 3.1 Gen2 is 10Gbps, USB 3.0 is 5Gbps, the loss of transmission speed loss After the USB 3.1 Gen2 can also support up to 900MB / s, while the USB 3.0 is only 500MB / s, the paper point of view, the gap is still relatively large. But we are most concerned about the ability of this hard disk box RAID set up, this performance test with everyone's favorite RAID 0 mode and dual-disk JBOD mode to read and write speed; and RAID 1's main function is to back up the data is not speed Upgrade, so this will not do a separate test. Test object: GALAXY 2.5-inch ONE series 120G SSD, 2.5-inch SSD is mainly used to extend the use of notebook storage. Because now Xiaobian hands do not have 2.5-inch HDD available, so we use the SSD to find out exactly because the formation of RAID is the need to format the hard drive, so we unified the hard drive before the test formatted to ensure that the test Fairness.  Before building RAID, let's take a look at the most common state of a normal SSD: Connect to the motherboard through the SATA interface to read and write data. This speed we should be able to guess, there is no accident, 500 + MB / s and 400 + MB / s continuous read and write speed, it should be everyone most commonly seen SATA solid state read and write speed.  Then came everyone loved the RAID 0, the test version for the USB 3.1 Gen2 interface speed version. Let me talk about this hard RAID switch, with its own flat-blade screwdriver to dial better, because the location of more reliable , Use your finger to use nails, in general, the formation of RAID arrays is still quite simple. After the formation of RAID 0, the hard disk 'new simple volume', you will be able to identify the fit after the hard disk.  CDM, AS SSD is the most commonly used hard disk read-write test software, and no other for the introduction.  From a few test software point of view, continuous read and write mainly concentrated in the 650MB / s-800MB / s range only from the above test data rough point of view, sustained read and write speed, Up to 40% more than a single SSD running the SATA channel, while 4K random reads and writes did not change much In general, continuous read and write speeds are up a notch, while 4K random reads and writes are the same. The above measured the speed of USB 3.1 Gen2, let's take a look at the speed of the more popular USB3.0 interface, as mentioned above, both 10Gbps and 5Gbps transmission bandwidth difference between the two, then the actual test in the end of the difference What about geometry?  basically, Continue to read 370 + MB / s, write 150 + MB / s As you can see clearly, USB3.0 bandwidth is not enough bandwidth brings the impact of the performance is still big. To sum up, The difference in speed between USB 3.1 Gen2 and Gen1 is still quite large , And need to pay attention to is that now most of the so-called USB3.1 interface is Gen1, that is, USB3.0 vest, only 5Gbps transmission bandwidth, so you want to get the highest speed experience, we must pay attention to yourself The interface protocol is not Gen3 USB3.1 agreement, but can not just look at this is not USB3.1. 'PConline evaluation room' summary  We have seen the 3 models of this Macwoodisk RAID mode, the data backup needs of the population can use two 2.5-inch mechanical hard drive to form its RAID 1 mode; and for the pursuit of read and write speed geek players, Can also use its RAID 0 mode, but the speed of SSD already very fast, Xiaobian reason to use SSD to test because there is no available 2.5-inch mechanical hard drive, but the formation of RAID 0 itself more suitable for mechanical hard drive; and dual-disc JBOD mode can be two hard drives together, due to small size, directly to the hard disk box as a removable hard disk box to use it is not a bad idea, anyway, it is about the size of a cell phone only. |
