Dual U-port, high-speed read/write, $1/GB solid-state USB flash drive to know

Reason for buying

In fact, at first there was no purchase plan, simply because during the 618 saw Patriot this U393 price is really good, 420MB / s write speed, 256GB version of the price is 1 yuan / GB, so I began to force myself to create demand:.

  • I have a need for mobile storage of data.
  • I often need to copy HD movies to play on my TV.
  • U-disk size to carry more convenient.
  • The all-metal casing and texture are also very good.

But, I already have more than one portable hard drive...

It doesn't matter! This Patriot U393 solid-state flash drive is more portable, more convenient to plug and unplug directly without the need for a data cable, and A and C ports to eat. Of course the most important thing is that it is too cheap!

So, it came to me under the escort of the courier boy.

Appearance

Open the box link to pass, directly look at the appearance and details of the workmanship of this U393.

Although it is a simple straight U disk shape, but you can see that Patriot still put effort in the design: silver white U disk, the dial processing is very delicate, the first feeling in the hand is very stunning, the feel is really nothing to say. In the official words, this is called "sports car shape". The newest addition to the line is the newest addition to the line.

The USB flash drive has a dual-head design, with one A-port and one C-port, for compatibility. The most critical thing is that it does not require two special data cables like SSDs, and the advantage of direct plugging and unplugging is completely unmatched by SSDs.

The interface is protected by a reversible cap buckle, with the aigo brand logo on one end of the front and the 256GB capacity logo on the other, the fonts are laser etched, so there is no risk of wear and tear with long-term use, which is essential for the quality of digital products.

The cap buckle can be flipped open, where the A-port is fixed by magnetic suction, the solidity is just right, usually not easy to open, when you want to use a finger gently dial can be turned down; C-port is fixed by mechanical card point, slightly tighter, when you want to use the two-hand operation will be more convenient ▲

Although the size is not large, but in the hand is still very weighty, weighed about 29 grams, and a Ling Mei studio acting almost ▲

Speed measurement

The way to examine a USB flash drive well do not use, of course, is to speed test. Is a mule is a horse, pull out to slip.

Port C

Port A

The first inevitable step is to run a score with AS SSD Benchmark, once on the C-port and once on the A-port.

The read speed of the A-port is slightly higher than that of the C-port, reaching 512.6MB/s, which is close to the standard 520MB/s, and the write speed of 423.86MB/s, which is slightly higher than the standard 420MB/s.

Port C

Port A

Next, we continued with CrystalDiskMark 8, again splitting the test between C and A ports. The result is that the read speed of C-port is still about 100MB/s lower than that of A-port, but the write speed is not much different.

It seems that port A does perform better than port C when reading data. This means that if you are just copying files from a USB stick to your computer, try to use the A port for faster speeds; if you are writing files, there is not much difference between the two.

Here are some more read and write tests. The actual test used are large files such as movies.

Empty disk reading

Let's first measure the read speed of an empty disk. The read speed of the empty disk is stable at around 400MB/s, which does not reach the official standard of 520MB/s, but is far above all mechanical hard drives on the market and comparable to most SATA port solid state mobile hard drives ▲.

Empty Disk Write

The write speed of the empty disk is stable at 314MB/s, which is also about 100MB/s lower than the nominal 420MB/s. This is comparable to the write speed of most solid state mobile hard drives on the market, which is a pretty good result for a small, heat-sinkable USB drive.

Half Disk Write

The speed fluctuates when writing continuously to about 1/3 of the capacity, not sure if it is affected by heat dissipation, but then it is stable again ▲

I think this fluctuation is acceptable, considering that such extreme continuous writing of large files is not common in life.

Full Disk Write

We all know that SSDs need to be carved out of the cache to improve their read and write performance. As the storage space gets compressed, the cache gets filled up and the drive starts to experience speed drops. So there is the term "slow out speed" - these are normal phenomena.

This Patriot U393 as a solid-state USB drive, of course, can not escape from this iron law.

When the USB flash drive memory is occupied to about 3/5, its write speed starts to decline. In other words, a 256GB capacity USB flash drive can actually read and write at high speed with about 160GB of storage space ▲

Full disk read

However, the read speed has not been affected in any way, and remains stable at slightly less than 400MB/s.

When the initial look at it, because of the value and cost-effective. Now the USB flash drive has been used for more than half a month, or very much like the design of this U393. I like to hold it when I'm in a daze or thinking about a problem, and it feels really delicate in my hand, and the flip cover design is quite decompression ▲

C-port connection

A-port connection

In actual use, the first thing I felt when I took it to replace my previous solid state mobile hard drive was naturally convenience. Although the speed is similar to that of a regular solid state mobile hard drive, the U393 is significantly smaller and more convenient to carry around.

And one A port and one C port design, compatibility is also very good, also do not have to drag an additional "small tail" (data cable) as with the SSD, in the convenience of use is really a class up.

But it is not without its slots: because of the all-metal case, so after a long period of continuous work, the heat generated by the flash drive chip will quickly be transmitted to the case. I checked with a thermal imager and the highest temperature was 57.6°C ▲

And because the shell is made of metal, so the thermal conductivity is particularly fast, when you pull it with your hands, the body will feel the heat more than other materials such as plastic. To put it bluntly, it is a little hot.

Summary

Dual U-port, high-speed read/write, $1/GB solid-state USB flash drive to know

At the end of the article, a brief summary of this Patriot U393.

  • U disk value is very high, double side waist line smooth, coupled with a delicate surface treatment process, excellent texture;.
  • Dual U-port design, good compatibility, basically everywhere you go without worrying about the lack of interface.
  • The measured read and write speeds are a little lower than the calibration, but the overall speed is quite good and better than I expected.
  • (a) Writing speed fluctuates after half a disk, and after 3/5 full disks, writing speed decreases, but reading speed remains the same.
  • If you just read the files on the USB flash drive, it is recommended to use the A-port operation, the measured speed will be slightly higher than the C-port 100MB/s, but the difference in write speed is not significant.
  • Compared to solid-state removable drives, this U393 is direct plug and play, does not require additional data cables, and is smaller and more portable.
  • Metal casing in enhancing the texture at the same time, but also brings the disadvantages, after continuous reading and writing casing temperature is high, the summer will have a hot feeling.

Overall, the price of about 1 yuan / GB, to buy this value and performance of the USB flash drive, I think this 618 is also worth ~

Insist on doing reviews with attitude and producing content with temperature. I am tomato, we will see you in the next article~
