You cann't be too good to be careful............ In simple terms, this sentence applies to any scenario, especially the use of digital products. But often the more careful it is, the more likely it is to make mistakes, such as the cup next to the computer. The more careful you do not touch it, the easier it will be to knock over, and the keyboard will be flooded. But compared to the keyboard water, the drop of the mobile hard disk is often easier to hurt, and the hard-copy things inside say nothing, especially for old resources or some important archive files that are not easy to find. For example, this self-assembled SSK mobile hard disk, which had just been dropped from the desktop to the ground three days ago, contains classic games such as the classic Yisu series, Xuanyuanjian series, and photographs and videos just taken from the outdoors on weekends. Now that the PC is unable to recognize the hard disk, hard disk-related software cannot recognize it, let alone fix it. So either throw away the hard disk or spend money to find a professional agency to recover it. In any case, the cost is somewhat high. The hard drive's breakage, coupled with the SSK hard drive box has been used for nearly 10 years, still stuck in the era of USB2.0 interface, so I feel it is necessary to re-purchase a drop-resistant hard disk box, and must be TYPEC -C interface, because it needs to be used with SSDs that have been eliminated. This is also the case, after comparing several brands directly to buy ORICO hard disk box 2539C3, in addition to meet the requirements of anti-drop, USB3.1 interface, but also joined the tool-free installation and dust-proof waterproof life of the design, must The degree is also the reason for the high price. ORICO hard disk box USB3.1 external 2.5 inch Type-c solid state USB3.0 notebook mobile hard disk box 188 yuan Lynx featured to buy This ORICO 2539C3 hard disk box supports tool-free installation, the whole is divided into two parts, one is the ABS material 2.5-inch hard disk box, the volume is 140mm*100mm*23mm; the second is the silicone sleeve around the hard disk box, the material is extremely soft This is mainly to rely on this to achieve anti-fall effect. It is also because of the design of the silicone sleeve that the bottom of the hard disk box is not designed with traditional foot pads. The thickness of the upper and lower parts of the silicone sleeve is about 3.1mm, which is not very thin. It guarantees the performance of anti-shock and shock absorption to a certain extent, so as to protect the internal hard disk. The hard disk box adopts the design of the trunk and the bottom is an integrated silicone pad design, which can be opened directly from one side. For the product mentioned waterproof and dustproof, relying on the surrounding gray silicone layer to achieve, from the point of view of the waterproof rating, is IP54, that can not completely prevent dust intrusion, but the intrusion of dust will not affect the normal operation of the equipment, At the same time, it can effectively prevent the intrusion of water from different directions (cannot be soaked in water), and basically meet the dustproof and waterproof effect in daily use environment. Compared to the design of silicone on the bottom, the upper cover does not have a design with a cushion. Therefore, the sponge pad included in the package needs to be installed to achieve the shock absorption effect of the hard disk surface. The design is somewhat simple. It is hoped that the lid will also be designed with the same silicone pad. The overall internal workmanship is relatively general. Since only one side buckle is used to fix the upper and lower covers, some joints will have the problem that they cannot be completely closed in terms of airtightness. This is a part of product design that needs improvement. The current treatment is to use a rubber band for reinforcement. The inside edge of the silicone is magnified and there is a raised raised wall near the interior to further enhance the protection against dust and water. Here is a detail worth mentioning, that is, the main control chip, it is not easy to dismantle, is the use of SATA3.0 (6Gbps = 768MB / S) master solution, and TYPE-C interface for USB3.1 GEN1 ( One generation), namely SATA3.0to USB3.1 GEN1 TYPE-C design, USB3.1 GEN1 maximum theoretical transmission speed 5.0Gbps (625MB/s), and the hard disk box supports the maximum hard disk capacity of 2TB. This is a post-installation rendering. It looks like the silicone pad fits tightly around the hard disk enclosure. How is the actual effect? First, try the waterproof effect. Use a water cup to flush 400ml of water directly from the top of the meter. Look at how the internal water enters. Most of the water will be ejected and some water will remain on the surface. At this time, the water can be thrown off if it is shaken. However, in order to verify the real effect, no drying operation is performed. Excluding the silicone sleeve, the outside of the hard disk cartridge also has residual moisture, which may penetrate into the interior through the hinge connection or the snap switch. After opening the HDD Enclosure, it was sure to see moisture at the edges, and water droplets on the surface of the HDD fell from the clip switch when the cover was opened. Fortunately, the interior of the hard disk box is still dry. Let's take a look at the drop-resistance effect. It can fall freely from a height of one meter three and fall twice. It can be recognized by the system when connected to a computer, which means that the anti-drop function is effective. Then, for the personal use, the required anti-drop waterproof performance has basically been met, let's take a look at the read and write performance of the hard disk. Below to match with the USB3.0 interface of the ZOTAC OI320 for testing, hard disk select Plextor SSD M6V, different hardware configuration of the computer equipment and the use of hard drives are different, in the final test rate will be different, the following The results are for reference only. Look at the theoretical value of the AS SSD test. Measure three consecutive times. Take the group with the highest read/write rate. On the left is the test data without the Plextor Turbo drive installed. Relative to the OI320 configuration, 418MB/s and 155MB The read/write rate of /s is fairly good on the performance. The right side is the data after installing Plextor Turbo drive. After the startup, the write performance is obviously improved. Let's use FastCopy to try the actual read/write rate, and also select the test data three times to select the maximum value. Among them, the D drive is a WD 1TB blue disk (mechanical hard disk) installed in the PC, and the G and F disks are external hard drives (Plexex SSD M6V). Whether reading or writing, the speed is stable at 86MB/s and 88MB/s, and the difference is not too great. On the other hand, Figure 3 shows the internal read/write rates of SSDs, which can be stable at 110MB/s. The ORICO 2539C3 HDD Enclosure is quieter in operation due to the internal shock absorption design. It will not hear the sound or vibration of the hard disk on the desktop. Simply make a summary, first of all, where you need to care about the use. The price is relatively high, not suitable for all players, suitable for people who focus on resistance to falls Workmanship on the airtight, design needs to be optimized, there is a big room for improvement No status indicator, the inner cover of the HDD enclosure has no shock-absorbing silicone design and can only be used with the included sponge Silicone sleeves need to be manually installed, the overall volume is larger than the common 2.5-inch hard disk cartridge Let's talk about the places where performance and performance don't show up Tool-free installation, convenient dismantling Excellent anti-fall performance to avoid accidental damage to mobile hard disk due to daily drop With a certain level of waterproof performance in life, it can prevent the internal water in the hard disk from being spilled. Read and write rate is stable, more in line with personal expectations In order to use a mobile hard disk with high frequency, it is indeed necessary to purchase a hard disk cartridge that resists falling, so as to avoid accidental dropping and dropping, so that valuable data in the hard disk cannot be read again.
