Foreword
I vaguely remember that when I was still studying, Dayuan used a 32M U disk from the school to the city’s Pacific Computer City. At that time, everyone was still using a floppy disk and I used a USB flash drive. Although not much used, Can be really easy to use, but also earn enough face, the key is more than a decade has passed, this U disk can still be used, but the USB 1.1 speed is still considered. Young people's first U disk, keep it commemorative.
Afterwards, many U-disks were purchased one after another. However, the borrowed and lost items did not leave a few of them. It was not a system installation disk that was a PE boot disk. Basically gave the mobile hard drive, and my first mobile hard drive WD Elements 500G also because of the bad USB interface, even a photo is not left, saying that the broken WD Elements 500G HDD is native USB interface, that is, the USB interface directly on the hard disk above the PCB, the interface hung up the disk will hang, anyway, now choose the mobile hard disk never choose that kind.
ASUS ZENDISK HDD
In my active portable storage, the ASUS ZENDISK mobile hard disk purchased in Hong Kong in 2012 was the longest in service. Lift the artwork on the hard drive, I believe we will think of the LaCie brand for the first time, and the ASUS ZENDISK mobile hard disk is actually a very texture, the front of the hard drive is aluminum alloy material, the surface and the A surface of the ASUS ZENBOOK ultrabook After concentric round wire drawing process, the texture is very delicate, with a hint of purple in the gray black.
Another selling point of this ZENDISK is its thinness, which is only 10.8mm thicker than a 9.5mm 2.5-inch hard disk.
However, the most painful thing for me is the non-slip rubber paint on the back of the hard drive. Although the anti-skid effect is very good, it is too easy to stick dust. After a while, it is estimated that the high temperature of the hard disk leads to the melting of the rubber paint. Now it feels sticky. Slimy, feel very disgusting.
In view of the fact that this disk has almost no anti-vibration measures and problems with stickiness on the back, it was later equipped with a shock-proof hard disk package that solved two problems at a time. However, it had previously been bought for the appearance and slimness, and now it has become a cloud.
The small pocket in front of the hard drive pack is just for the data cable. One of the bad things about this hard drive is that the original data cable is too short. The friend who bought it with me finally bought a long data cable.
The total weight of 230g is not heavy, but it is not too light.
Apart from being thin, the inclusion of a 500G 7200RPM Western Digital black disk made it one of the best portable hard drives of the time. Although performance is not worth mentioning with today's large-capacity mobile hard drives, it was difficult to find such a high-performance mobile hard disk at that time. Of course, the high calorific value and the high vibration are also the side effects associated with high performance.
Easy drive line + SSD
In fact, my portable data is not much, 500G mobile hard disk also uses a small part of this, plus the SSD on hand idle, so later gradually replaced the original mobile hard disk with the combination of easy drive + SSD.
The advantage of this solution is that it is fast and it is not afraid of vibration. The small capacity is not a mere injury. After all, the large-capacity SSD is not a rarity. As long as the purse is not difficult to use, this solution can be used to combine large-capacity and high-speed portable memory. If you think that the combination of easy-to-drive + SSD is not very secure, you can use a removable hard disk drive instead of an easy-to-drive drive. However, it is easier to use the drive and it can be replaced at any time.
For the sake of beauty and reduced grinding, it is finally equipped with a relatively thin hard drive package.
The size is just right, the data line is exposed from the gap in the chain, it is quite convenient to use.
Compared with the previous mobile hard disk and shockproof package, the combination of light weight is about 100g, in fact, the weight is not the biggest problem, good shockproof effect is the key, after all, usually work packages are thrown around.
The performance of this combination is affected by the three factors of SSD, easy-to-drive and USB interface at the same time. Although the speed is much slower than that of the SSD running under the SATA interface, the read speed of the SATA interface can exceed 500 MB/s. Almost), but it still has a big advantage over mechanical hard drives.
Kingston USB3.1 HyperX Savage U disk
However, after the last time I used my colleague's SanDisk CZ80 U disk, I found that the high-performance U disk was actually very convenient, and the speed used to be similar to the combination of the easy-to-drive + SSD before, so I thought about starting with one. High-speed U disk, but I missed the N times the sea Amoy good price I still did not start, eventually in the East during the 618 period Kingston U disk every 100-20 hit the HyperX Savage U disk.
U disk surface is black rubber paint, red "X" part is metal, and this "X" just forms a groove for easy grip.
U disk capacity identification and blue read and write lights at the end and with a hanging hole, so expensive a U disk lost very distressed, so usually always love to throw things remember to carry a big thing behind.
In fact, I quite like the design of the SanDisk CZ80's retractable USB interface, because the lid is not easy to lose, but compared to the HyperX Savage U disk this design has a certain degree of waterproof, and the cover can be buckled behind the U disk, of course, If the U disk behind the rope after the lid can not be covered, so usually still pay more attention to protect the cover.
It is estimated that because the red part in the middle of the U disk is metal, the entire U disk is quite heavy on the hand, but compared to the previous two, this is simply not worth mentioning.
Checked with ChipGenius, U disk is the group leader + Toshiba MLC particles.
128G disk, there is 117G available capacity after formatting.
This saying uses the USB 3.1 Gen1 interface, but it is not problematic to use it under the USB 3.0 interface, and the performance is fully up to speed.
Pinnacle duel
The previous test has roughly understood the read and write speeds of the three devices. Then use FastCopy software to copy a 20.2G folder (Tomb Raider 10 game folder) to the external memory to see the actual of the three devices. Spend time.
The ASUS ZENDISK mobile hard disk took 216 seconds at an average speed of 95.75MB/s, which is close to the software test results.
The combination of Easy Drive + SSD took 118 seconds and the average speed was 175.06MB/s, similar to the speed of the previous software test.
Finally, the HyperX Savage U disk, which took 71 seconds to copy, with an average speed of 292.49MB/s
Write last
At present, this U disk has replaced the position of the first two predecessors, but there are some embarrassing things encountered in use. For example, when copying data on a machine that only has a mechanical hard disk, the speed is restricted by the mechanical hard disk. Can not play a speed advantage, and the other is that this U disk is a little expensive, after all, this price is a full reduction can almost smash a 480G SSD, of course, compared with the same paragraph with Huang Sicong is only dribbling.
