As we enter the digital era, the amount of data generated by individual users is increasing day by day. The massive data needs reliable transfer and backup equipment, among which the mobile hard disk is one of the most commonly used methods. In recent years, with the rapid development of solid-state disk technology, higher speed mobile solid-state disk has gradually become popular. < / P > < p > compared with the traditional HDD mobile hard disk, the mobile solid-state disk not only has higher transmission speed, but also is more robust and shockproof, which can greatly improve the efficiency of data transfer in daily use. In addition, for some old notebook computers with small hard disk capacity, high-speed mobile SSD can also be used as external disk to expand user space. < / P > < p > the product tested below is a mobile solid-state hard disk from WD, a subsidiary of Western data_ Black Brand P50 game mobile solid state drive. WD_ Black is a high-performance brand specially launched by western data for game players. Its products have excellent performance. P50 also provides top-level specifications. It adopts vme1.3 protocol, pciex4 channel, and supports USB 3.2 gen2x2 high-speed interface. The official maximum sequential reading speed is 2000mb / s. let’s have a detailed understanding of this product. < / P > < p > appearance, WD_ The black P50 mobile solid-state drive adopts a very special design. The aluminum shell is made of fine workmanship and excellent texture. The horizontal ribs make the whole hard disk look like a small container. < / P > < p > the four corner decorative screws add a bit of hard core quality to the hard disk. The solid design of the whole machine not only can effectively protect the internal memory chip, but also has a certain anti shock ability, which can guarantee the normal use under the bad working conditions.
WD_ The bottom of the black P50 mobile solid-state drive adopts a horizontal grid, which is conducive to rapidly expel the heat generated inside during operation. The overall size of P50 is 118 * 62 * 14mm, which is equivalent to a 4-inch mobile phone, with a net weight of 115g. It is small and portable. < / P > < p > in the crystal diskinfo message, this hard disk is displayed as WD_ Black sn750e should be connected with WD_ The m.2 nvme SSD sn750 of black brand is the same memory chip. We tested WD before_ Black sn750 has a maximum sequential read speed of 3500mb / s, so it is not surprising that P50 can reach 2000mb / s. P50 supports nvme 1.3 protocol and USAP. Uasp is a transmission protocol made by usb-if, which can improve the transmission speed between USB interface and high-performance host, and reduce CPU utilization, data delay and waiting time. < / P > < p > first, we use the Atto disk benchmark. Atto disk benchmark mainly tests the transmission speed of hard disk to files of different sizes. The red bar is the writing speed, and the gray bar is the reading speed. The file size increases from 512b to 64MB. According to the test results, WD_ The performance of black P50 mobile solid-state disk is very good. In the test of reading and writing files above 128KB, the average reading and writing speed is over 900mb / s, the maximum writing speed is 976mb / s, and the maximum reading speed is 1021mb / s. < / P > < p > finally, we use txbench software, which is also a commonly used professional disk performance test software. In the aspect of sequential read and write, in 32 queue single thread, WD_ The sequential read speed of black P50 is 844.61 MB / s, the sequential write speed is 996.34 MB / s, the random read speed of single queue single thread 4K is 26.52mb/s, and the write speed is 72.67mb/s. Compared with the previous software, the performance is still stable. In terms of the actual transmission speed, first of all, let’s turn to WD_ A 17.7GB folder containing pictures, executive files, compressed packages and system files is copied in black P50 mobile solid state disk. Due to the complexity of file types and different sizes, the actual transmission speed fluctuates greatly. The maximum write speed is 676mb / s, and the average write speed is about 200MB / s. < / P > < p > secondly, we copied a folder composed of several high-definition movies into it, with a capacity of about 8GB. The actual average write speed is about 670mb / s, which is very stable. It takes only 15s to complete all the writes.
WD_ The black P50 game mobile SSD is compatible with high-performance Game PC, Sony Playstation 4 / Pro game console and Xbox one game console. It can help the game console expand storage space, get faster game loading speed and reduce the time required to enter the game by connecting to the console through USB interface.
WD_ As a high-performance sub brand specially launched for game players under western data, black brand is committed to providing users with higher performance and more extreme use experience. For gamers, WD_ Black P50 mobile solid state disk is not only a reliable tool for massive game backup, but also can be used to expand the storage capacity of its own game console and improve the game experience. For feverish gamers, it’s worth considering. Continue ReadingXiaomi new machine real machine exposure center dig hole screen design or high color thousand yuan machine
