Recently, the company moved out of the new office building, and it has since got rid of the situation of working under the leadership of the leader. As a result, during leisure, he secretly engages in some recreational activities and is not afraid of anyone staring. However, because the computer of the unit has confidentiality requirements, the content of entertainment cannot be stored in the computer of the unit and can only be played secretly through the mobile hard disk.
I already had a 2TB mobile hard disk, which is mainly used as a data warehouse. Although the capacity is large enough, due to the speed limit of HDD, I have no SSD, I have a high-speed U disk or mobile hard disk. The idea.
Just started planning to directly buy a high-speed 3.0 U disk, the results went to an East search in a circle, can reach 300M / s 256G U disk prices are above 1000, and those 4,500 yuan, are reading 100M / Around s, write less than 100M / s slag cargo.
After much deliberation, I simply bought a SSD and USB3.0 mobile hard disk box to assemble my mobile SSD. Due to the higher formaldehyde content in the newly renovated office, I bought 6 kg of activated carbon.
My Black East side is the next day, Pu Kete M7VC 256G SSD and ORICO 2569S3 mobile hard disk box, the following I slowly talk about why you want to choose these two things.
Look at the SSD, Heidong 479, won with the coupon 459, because it is used as a mobile hard disk, so there is no need to buy too advanced disk (SATA3.0 transmission rate of 6Gbps, USB3.0 transmission rate of 5Gbps, so USB3. 0 will limit the performance of high-end SSDs. The M7VC of TLC particles will be sufficient. In any case, the brand and quality of Plextor are relatively reliable.
The Plextor M7VC's packaging is red and white and looks very simple. 
On the back is some performance indicators and technical parameters.
The attachment is very simple, except that the body is the manual and warranty card.
Metal shell, just this color reminds me of a song: Shandan Dan blooming, red Yan Yan.
Fortunately, the back sticker is white.
Standard SATA3.0 interface.
Followed by the choice of USB3.0 mobile hard disk box. Do not look at the mobile hard disk box structure is simple, but there are many fame. The most important one is the master chip, followed by price and workmanship. After some review, we know that the current performance of the SATA3.0 to USB3.0 chip is ASM1153E and JMS578. From the performance point of view, the ASM1153E is slightly dominant. From a functional standpoint, JMS578 dominates because JMS578 supports Trim functionality. Initially intended to buy JMS578 products, the results did not find in the Black East, can only go to a treasure to buy, I in order to scrape a single coupon (charcoal package + hard disk box), they bought ORICO's 2569S3 in Black East.
Hard disk box packaging is also very simple.
back.
The attachment is also very simple.
To be honest, this box looks okay, but I'm not very satisfied. Because the shell is plastic, it is not conducive to heat dissipation, but considering its price of 45 yuan, it also endures. Yuangu has a chip workmanship. OK, but more than 100. . . . .
back.
There is an arrow on the back, which is pushed in the opposite direction of the arrow and opens.
Mount the M7VC into the hard disk drive.
Insert the computer and initialize it first.
Then is the partition, and the partitioning software uses partition wizards.
There is no difficulty in this, and the old drivers understand that 4K alignment is justified.
SSD's SMART information can be seen as 0 power, this second-hand East did not give me second-hand goods, fortunately.
Simple test it, the test host configuration is roughly: 6600K + ASUS Z170-AR, the main board is Intel S3500 480G, M7VC connected to the SATA interface when hanging from the disk, the operating system is WIN10 64, the disk drive for the system comes without Intel IRST driver.
AS SSD Benchmark test, from the point of view, USB3.0 mode was completely burst by SATA3.0 mode, but I only need to continue reading and 4K read fast enough, and these two indicators, USB3.0 mode compared to SATA3 The .0 model is a little bit less, and it is a tolerable range of losses.
In the TxBENCH test, the read speed in the USB3.0 mode is still relatively close to that in the SATA3.0 mode, and the performance of the ASM1153E is really good.
In the CrystalDiskMark test, the speed of USB3.0 mode is slightly higher than that of SATA3.0 mode, but it is still in a tolerable range.
Try to load the game speed, use the stopwatch to record GTA5 loading time, we can see, USB3.0 mode is only 2 seconds slower than SATA3.0 mode, the performance loss is very small.
After the above tossing and testing, I confirmed that this set of programs is feasible, so I copied a lot of games at home. . . . . Who knows, the game does not occupy the space of the SSD, then they have copied some big sister's videos to explore the mysteries of human science. Then began to use, compared to the mechanical mobile hard disk, SSD mobile hard disk really is the 6's fly.
Finally sum up some of the tossing experience:
1. Select SATA3.0 to USB3.0 HDD box, chip is the key, although USB3.0 is not born with SATA3.0 fast, but a good adapter chip, can minimize the performance loss, the best performance The chip is ASM1153E, but the price of the product is quite different. You can choose according to your needs.
2. For the choice of SSD, the first consideration is the price, followed by the brand and quality. After all, switching to USB3.0 mode has a loss of performance, so even if you use the most advanced SSD, put it in a mobile hard disk box, and ordinary The SSD gap will not be too big.
3. Although the mobile SSD hard disk is relatively large compared to the U disk, it has the advantages of large capacity, high speed, and low price. Compared with the HDD mobile hard disk, it is not afraid of falling, and is suitable for use in harsh environments.
