The term “mobile storage device†is a bit of a mystery for most people. In fact, it should be something that everyone will have. Everyone’s familiar U disk is a mobile storage device, then a large-capacity mobile hard disk, and a faster-speed portable solid-state hard disk. For those students who are already working or at school, these things should be necessary. I can't live without a mobile storage device as a design student class. My usual plans for painting in school rooms are Save to u disk to go back and continue to draw, and then save it to u disk the next day to guide the work to the teacher or the next day and then export the computer in the school room to continue to do, and the design is motionless is a few G, and at any time on weekdays To go to print shop print plans, photos, documents, nothing to save but also some movies, documentaries and the like, as well as the habit of putting camera photos on a U disk, so my needs for mobile storage devices: carry, capacity, Cost-effective. Comprehensively, the first high-priced portable solid state drive is sure to be passed. Although the mobile drive has a large capacity and high cost performance, it is inconvenient to carry the pass. Therefore, u disk is left to be selected, and the u disk is selected to be portable at any time. Used, the beginning is to just buy a just about it, point to open the dog to search for Kingston U disk, found to focus on the super super small can hang in the key chain and inconspicuous mini u disk DTMC3 128GB, and the price and other The style of Kingston U disk no difference, he
Kingston DTMC3 128GB USB3.1 Reading Speed ​​100MB/s Metal U Disk Silver Portable Ring Jingdong Direct Link 
U disk or into the year ago, used in the original article issued by the mother of the gold exchange point of the E card plus Jing beans, the final payment of 58 hands and found that the 128GB version is now out of stock, the largest only 64G version, ha ha ha ha!
specification:
DT series is a Kingston entry U disk, this series has a metal shell and a large key ring, as basic products are TLC flash memory particles, low cost TLC is inevitable, there is a higher end of the HX series is a sub-brand HyperX U disk, HyperX U disk flagship speed durable, no doubt is a better MLC flash memory particles, yes, Kingston U disk certainly can not do without DT HyperX Predator USB3.0, but the national husband Wang Sicong same paragraph ah
In fact, I really don't like U disk as a one-time packaging, but every brand is like this.
Surface read speed 100MB/s
U disk is small, the nail cover is large, remove the buckle can be done smaller
DTMC3 has a 16-128GB version, priced at 79-299 yuan respectively, but now 128GB version of Dog East has been removed

Side of various models and U disk information
Compared to the Kingston HXF30 64GB and SanDisk TF card I purchased in 14 years, I know how small it is.
This U disk has a drawback is ~ as shown above, obviously two traces
Group PS2251-07 master, with Toshiba TLC flash memory particles, most U disk market use this set of master control program
Performance Test I used to test some of the conventional software when evaluating SSDs
The AD SSD Benchmark test only measures continuous writing, because the basic work of the U disk is basically continuous reading and writing, unlike SSDs as the system hard disk needs to deal with a large number of broken files, so random 4K and queue depth is very important for solid state drives, AD SSD Benchmark continues Reading 130.08MB/s, writing 20.42MB/s, much faster than the official 100MB/s
The CrystalDiskMark test continuously reads 135.2MB/s and writes 20.13MB/s. CrystalDiskMark's test project is basically the same as the AD SSD Benchmark test above, but its final score is the best score of 5 tests, so the general test score will be better than the AD SSD Benchmark. To be higher.
ATTO Disk Benchmark continuously reads 133.32MB/s, writes 18.71MB/s
HD tune benchmark minimum 100.4MB/s, maximum 139.3MB/s, average 130.3MB/s, data is basically the same as above
Actual file reading averaged at 127MB/s
Write 17.6MB/s
Plus a group of my Kingston HXF30 64GB I bought in 14 years to compare, although it is an old retired product, but it is at least MLC flash memory
The same group PS2251-07 master, but with the Toshiba MLC particles
The speed of MLC is obviously not a level with TLC, but the USB-constrained bandwidth does not expect U disk to have a solid, unnatural performance.
