In the era of big data, security and confidentiality have become the most important hidden danger in information technology, especially USB flash drives, which are used to transmit data between various devices. They have become the hardest hit area by viruses and Trojans, especially in scientific research and state-owned enterprises. , government, military and police, high-tech, business and other departments, once the transmission carrier of important data is lost, the loss will be irreparable, and a safe data storage and transmission medium is urgently needed.

PHIXERO push-button hardware encryption USB flash drive UP3-PW came into being. It has security protection measures such as hardware encryption, metal shell, high-speed transmission, smart chip, multi-digit password, smart self-locking and self-destruction. Let me explain one by one, hereafter referred to as "UP3".

UP3 is packaged in a minimalist and environmentally friendly carton. There is an integrated plastic storage compartment inside, which effectively protects the USB flash drive from being damaged by extrusion, vibration, bumps, and damage during storage and transportation. The interior includes a UP3 and an instruction manual. One serving.

UP3 uses one-piece zinc alloy as the shell material. It weighs 61 grams. It feels heavy and heavy when held in the hand, which makes people feel more at ease. Metal materials have higher strength, hardness and heat dissipation performance, ensuring that UP3 is sturdy and durable. You don't have to worry about damaging the internal chips due to bumps and bumps. After all, zinc alloy is an outdated material. If titanium alloy is used, it will have higher strength, lighter weight, and more skin-friendly properties.

The appearance size of UP3 is: 79 x 26 x 11.5 mm in length, width and thickness, which is a decent size. The surface is elegantly painted gunmetal gray, which reflects the texture of the fuselage. It is beautiful and durable, and there are almost no fingerprints during use. Residue.

The front of UP3 is a numeric input keyboard, which is the input area to ensure physical encryption and unlocking. The lower part of the front is spray-painted with the PHIXERO trademark in white. The appearance is relatively compact, and the body is not made for the repeated pursuit of portability. It is relatively small, and I personally think this is more suitable for carrying and using. On the one hand, it ensures more comfortable input, and on the other hand, it is easier to find the USB flash drive in the bag.

If you are still worried about losing it and it is difficult to find it, there is a long lanyard hole on the back of the Fischer Shield USB flash drive UP3. It would be better if it can be equipped with a hand strap as standard. The inner edges of the hand rope hole are polished and painted gray to effectively prevent the hand rope from wearing and tearing during use.

Above the hand strap hole is the product model and manufacturer of UP3. It is a domestic U disk, so there is no need to worry about leaving a backdoor and leaking secrets. UP3 is available in three capacities: 32G, 64G, and 128G. I bought the maximum capacity of 128G. Of course, the price is also the highest. 1G is less than 2.6 yuan. The price/performance ratio is the highest among the three brothers.

The entire body of UP3 is treated with metal polishing process, and the corners are arc transition processed. There are no sharp edges and corners on the whole body, ensuring good grip and stability of use, and there is no need to worry about scratches. Bad clothing.

UP3 has a maximum 15-digit password encryption. Compared with software encryption, I personally think that hardware encryption is safer and less difficult to crack. Of course, compared with ordinary USB flash drives without any protective measures, even if UP3 is accidentally lost, there is no need to worry about privacy leakage.

The 12 buttons of UP3 are arranged in groups of two, with 6 groups arranged in parallel vertically. The surface is covered with a rubber cap, which not only increases the feel, but also provides waterproof and wear resistance. The key travel is about 2mm, and there is a clear feel and sound feedback when pressed.

Above the numeric keys are the lock and unlock indicator lights on the left and right respectively. In addition, when the USB port is plugged in without unlocking, the blue light on the left side lights up, indicating that the UP3 is being charged. UP3 is powered by a built-in lithium battery with a capacity of 120mAh, which can be used for more than 6 months on standby. It can be charged as long as it is used, which is very convenient and enables offline hardware encryption.

The hardware-encrypted USB flash drive UP3 can automatically lock to automatically protect data security when the power is off or has not been used within 30 seconds of unlocking. The red indicator light on the right side is on when locked, and the blue indicator light on the left side is on when unlocked.

If you want to use UP3, you need to press and hold the power button in the lower right corner. After the red indicator light lights up, enter the password through the numeric keyboard. During the input process, the two indicator lights flash alternately. After entering the password, press again Press the unlock button in the lower left corner to unlock. The blue indicator light remains on and the operation is relatively smooth. The password operation is implemented on the USB flash drive and will not leave any traces on the computer. It is very difficult to crack it.

UP3 uses built-in independent chip hardware encryption, AES256 encryption scheme (Advanced Encryption Standard, Advanced Encryption Standard), which is said to be a symmetric key encryption algorithm of the US military, with a 256-bit key, specific content It's more complicated than popular science. Anyway, as long as you remember to crack it, it is much more difficult than directly kidnapping the administrator and asking for the password. There is no possibility of external force cracking it.

UP3 supports passwords with up to 15 digits, which is the possibility of assigning 10 to the 15th power of passwords. The total number of passwords supported is 6~15 digits = 10 ^ 6 10 ^ 7 ... 10 ^ 14 10 ^ 15. I haven’t read much, so I can’t calculate it. If your UP3 is accidentally lost, as long as you enter the wrong password 10 times in a row, sorry, UP3 will automatically destroy all the stored data, leaving no chance for anyone who wants to steal the secret. Don't even think about brute force cracking, building a barrier for the data. safety barrier.

UP3 looks like a USB flash drive at first glance, and it is a large-capacity USB flash drive that supports USB3.0 or USB 3.1 Gen1. The theoretical maximum transmission bandwidth is 5.0Gbps (500MB/s). Although It's not Gen2, but its speed is enough for a USB flash drive.

The standard USB-A interface is suitable for Windows, OS and other operating systems. As long as the computer's USB interface supports protocols 3.0 or above, it can achieve high-speed data transmission performance.

The blue base and internal gold-plated contacts both indicate that this is a device that supports USB3.0 high-speed transmission. Gold plating can ensure that the contact resistance is minimized, and it also makes it easier for the system to identify the following five The contact point will not be misjudged as 2.0.

UP3 uses eMMC (embedded Multi Media Car) particle master control, which is essentially just a standard set of I/O interfaces and physical layer implementations for embedded devices. It has simple interfaces, small size, and high functionality. It has the characteristics of low consumption, but compared with SSD, it has smaller capacity and slower random reading and writing. It is mainly used as a storage medium for USB flash drives, mobile phones, tablets, etc.

When you get the new disk, first go to the computer to check the capacity. It is in FAT32 format, 116Gb. Don’t ask me why it is not 128Gb. Anyone who can see this will understand, so I won’t go into details. It is recommended to format it yourself in NTFS format, which can support a single large file.

Although it took a long time, it successfully passed the bad block detection and data integrity check. There are no problems with the capacity and quality of UP3.

Using MyDiskTest for testing, the 512K random read speed is 197MB/S and the write speed is 172 MB/S.

The 32M random read speed is 113MB/S and the write speed is 95.1 MB/S.

Using CrystalDiskMark, 1GB data volume, 1M sequential read speed 194Mb/S, write speed 129Mb/S; 4K random read speed 12.48 Mb/S, write speed 10.09Mb/S.

Under the 8G data volume, the sequential reading and writing speed is faster, 1M sequential reading speed is 235Mb/S, and the writing speed is 180Mb/S; the random reading and writing speed is slightly slower, and the 4K random reading speed is 11.71Mb/S, writing speed 9.32Mb/S.

Let’s take a look at the actual reading and writing speed. The computer is an SSD hard drive, WIN10 operating system, and USB3.1 interface.

The speed of UP3 can maintain over 200MB/S for a long time when reading large volumes. At this speed, it is enough to transfer a movie in five seconds.

In terms of writing speed, it can remain stable at around 135MB/S for a long time. The transmission speed of UP3 is enough for daily use. Anyway, it is second only to my solid-state mobile hard drive with USB3.2 interface.

PHIXERO push-button hardware encryption high-speed USB flash drive UP3-PW has an independent physical keyboard input function, a built-in battery to maintain offline encryption, a military-grade hardware encryption solution, and an intelligent self-locking and self-destruction protection mechanism. The fast data reading and writing capabilities enable each user to have an exclusive private data space, protect the security of important data, create a security barrier for you, and help you realize digital smart storage.
