UFS 4.0 Has 2,800MB/Second Write Speeds

Samsung claims to have created the industry’s highest performing Universal Flash Storage (UFS). With read speeds of up to 4,200MB/s and write speeds of up to 2,800MB/s, UFS 4.0 is twice as fast as the previous generation.

Not only is UFS 4.0 faster than previous generations, but Samsung claims it also consumes less power. As a result, the company claims that it will be at the heart of future mobile storage solutions, having a dramatic impact on smartphone performance as well as having a significant impact on augmented reality (AR) and virtual reality (VR) hardware.

According to Samsung, UFS 4.0 comes in a small package that measures 11mm by 13mm by 1mm and can support capacities of up to 1TB. This 1 TB has a sequential read speed of 6 MB/s per mA, a 46 percent improvement over the previous generation’s power consumption.

“UFS 4.0 offers up to 23.2Gbps per lane, which is double that of the previous UFS 3.1,” Samsung claims. “That much bandwidth is ideal for 5G smartphones, which require massive amounts of data processing, and it is also expected to be used in future automotive applications, AR, and VR.”

The performance is also impressive, with a sequential read speed of up to 4,200MB/s and a sequential write speed of up to 2,800MB/s promised. The previous generation, UFS 3.1, could promise write speeds of up to 1,200 MB/s. More than doubling the previous generation’s speed while using nearly half the power is likely to have a significant positive impact on device performance.

JEDEC, the Solid State Technology Association, an independent semiconductor engineering trade organization and standardization body, has approved the UFS 4.0 standard specification. Samsung says mass production of UFS 4.0 storage will begin in the third quarter of 2022, and that it is collaborating with smartphone and consumer device manufacturers from around the world to create an ecosystem of support for UFS 4.0 to make market adoption easier and faster.

3D NAND was developed in response to the scaling limitations of 2D NAND memory.

The layers in 3D NAND were flipped from horizontal to vertical orientation and strings of them were built to form a tower. By changing the direction of how the cells are configured created opportunity to increase storage capacity, reduce size of the storage area and reduce the power consumption to access the cells.

Honestly, it’s a complicated explanation to describe the changes between 2D and 3D NAND, but we found this awesome video from TechTarget. The video is very direct and to the point without over complicated explanations. Please watch it. 2min 20 seconds long.

Micron Technology, Inc. (Nasdaq: MU) has announced the availability of a sample of the world’s first vertically-integrated 176-layer NAND solid-state drive (SSD) for data center applications. This new data center SSD features Micron’s industry-leading NAND with 176 layers of storage cells and proven CMOS-under-the-array technology for an ultra-efficient design.

Last year, organizations that used high encryption standards for data at rest and in motion paid 29.4 percent less for a data breach than organizations that used low or no standard encryption. Micron SSDs include self-encrypting drive functionality and Microsoft eDrive options to help protect against data breaches and tailor security to specific data protection needs.

For the purpose of this article we are explaining the difference between “disc” and “disk” in relationship to the terms applied to technology products.

The term “disc” is most often referred to data storage in the form of optical media.

The term “disk” is most often referred to data storage in the form of hard drive or solid state drive media.

It is also said the spelling “disc” is more commonly used in Europe to describe data storage products; whereas the spelling “disk” is more commonly used in the United States.

From our understanding the origins of “disk” to describe data storage is rooted from the floppy diskette days. Users, resellers and manufacturers would shorten the word “diskette” to simply use the word “disk.” ( ref )

Once optical media such as CD and CD-R came to market the term “disc” was used to describe the product because of the product shape. The Latin word “discus” is used by the Greeks to describe “dikein” which is “to throw” and to throw and object which was flat and round.

As the years past with CD and CD-R and then DVD and DVD-R it came even more common for technology users, resellers and manufacturers to use the spelling “disc” to describe their optical media products.

Here at GetFlashMemory.info we see many versions of the spelling when describing a USB flash drive or disk. The correct spelling when related to a USB flash drive would be “USB disk.” This is true because the data storage device does not have a physical shape which is round.

About one year ago, we did report on a USB flash drive which emulates CD-ROM optical media when connected to computers, called the Disc License drive. In this situation the spelling for “disc” is correct because the product emulates that of a circular optical drive. This product is a WORM device (Write Once Read Many) which means the data on the USB drive cannot be modified, changed, manipulated or deleted.

From all accounts it appears Aleratec closed their doors and out of business from sometime starting in February, 2022.

GetUSB.info attempted several calls to the corporate office in search of comment, but received no response. Furthermore, it appears that Google has removed Aleratec from their search results because their domain www.aleratec.com has been inactive for more than 30 days. We are posting this information in case end-users are looking for company support or warranty information.

Aleratec, Inc. was a family-owned California-based company with two decades of experience designing, developing, and marketing high-performance, dependable, and easy-to-use products.

Greg Morris, CEO of Nexcopy Inc, a similar company profile and also based in Southern California commented today after request, “I’ve known about Perry Solomon, the CEO, well over twenty years and he was always a good person to speak with regarding industry trends and business practices. Extremely friendly and approachable. Perry was focused on bring a solution to the market which brought true value to the end-user. I wish him the best of luck with his next business adventure.”

Aeratec offered PC-based and standalone flash memory duplicators, as well as CD and DVD duplicators, hard drive duplicators, and hard drive demolishers. In addition, Aleratec provided a “charge and guard” cabinet for charging portable devices such as tablets. The charge and guard cabinet proved especially useful in schools.

Some products are still available online at the time of this posting, but the majority of models appear to be out of stock or on back order.

Micron announced the industry’s first 3D NAND memory device with 232 layers on Thursday. The company intends to use its new 232-layer 3D NAND products for a variety of applications, including solid-state drives, and expects to begin mass production of such chips in late 2022.

Micron’s 232-layer 3D NAND device has a raw capacity of 1Tb and a 3D TLC architecture (128GB). The chip is based on Micron’s CMOS under array (CuA) architecture and stacks two arrays of 3D NAND on top of each other using the NAND string stacking technique.

The CuA design, combined with 232 layers of NAND, will significantly reduce the die size of Micron’s 1Tb 3D TLC NAND memory, allowing Micron to price devices featuring these chips more aggressively or simply increase its margins.

Micron did not specify I/O speeds or the number of planes in its new 232L 3D TLC NAND IC, but it did state that the new memory will outperform existing 3D NAND devices, which will be especially useful for next-generation SSDs with a PCIe 5.0 interface.

Speaking of SSDs, Micron’s executive vice president of technology and products, Scott DeBoer, stated that the company has worked closely with developers of in-house and third-party NAND controllers (for SSDs and other NAND-based storage devices) to ensure proper support for the new type of memory (and make sure those upcoming drives end up in our best SSDs list).

“We optimized [232-layer 3D NAND] technology around what we need to make the world’s fastest managed NAND and both datacenter and client SSD products,” said DeBoer. “The combination of controllers, both internal and external, has been a strong element of our vertical product integration focus to ensure that we have optimized NAND and controller technology for what we need to deliver future leadership products.”

Among the benefits of its 232-layer 3D TLC NAND are Micron mentioned lower power consumption compared to previous-generation nodes, which will be another advantage given Micron’s historical focus on mobile applications and relationships with device makers.

Given that Micron will begin production of 232-layer 3D TLC NAND devices in late calendar 2022, we can expect SSDs powered by the new memory to arrive in 2023.

Help! Is a TF card or microSD card required for my device? What IS the difference?

When it comes to memory cards, the market offers a plethora of options aimed at various devices. TF cards and microSD cards are two of the most well-known of these options. These cards are used as primary or secondary storage devices in a wide range of devices.

Having said that, there is some misunderstanding about what a TF card is. Is there a distinction between a TF card and a microSD card? Is it the same thing? Which one should I choose?

What Is a TF Card?

In 2004, Motorola and SanDisk introduced TransFlash (TF) cards as a replacement for SD cards. Secure Digital cards (SD cards), as you know, are memory cards used in digital cameras and other devices which require portable storage. Although SD cards are the most widely used storage format, they are larger and more cumbersome than a TF card.

TF cards were designed to be smaller and more compact than SD cards while still retaining SD card functionality. This means you can use a TF memory card in your digital camera or any other device that accepts an SD card with the help of an SD card adapter.

What is a MicroSD Card?

MicroSD cards are simply rebranded TF cards. When Motorola and SanDisk released the TF card in 2004, it was released as a separate standalone product. Aside from the fact that TF cards supported the same standard specifications as SD cards (except for the size), they were a distinct, non-standardized product class.

The SD Association, which is the governing body over the Secure Digital specifications and compliance guidelines, adopted TF cards as microSD cards to standardize these flash memory cards.

So, microSD cards are TF cards in disguise.

TF Card vs. microSD Card: What’s the Difference?

There are no distinctions between TF cards and microSD cards. Both can be used interchangeably. For example, if you have a TF card but your smartphone only supports microSD cards, you can use your TF card. It will work perfectly because it adheres to the same standard.

Which Card to Pick Up?

If you need a memory card for your digital camera or older gadgets but don’t need one for your smartphone, a full-sized SD card is the way to go.

On the contrary, if you need a card for your smartphone alone, you have no other option than a microSD card.

Finally, get a microSD card with an SD adapter so that you can use your card in both your smartphone and other devices. Because MicroSD cards use the same standard interface as SD cards, they can be used in place of SD cards with the help of an SD card adapter.

Copy 1GB of data every 30 seconds with the all new 16 target SD Card Duplicator by Nexcopy. Improved copy speeds result in ultra-fast Secure Digital copier outperforming all other systems.

The all new SD160PC is a computer connected SD Card Duplicator manufactured by Nexcopy Inc., a California based technology company. The Drive Manager software is written and developed by Nexcopy and provides Users with the most feature rich software to perform the most complex data load projects.

• Copy 1GB of data to all sockets Every 30 seconds.
• Read CID numbers from Secure Digital cards.
• Drive Manager software provides six copy modes.
• Software supports any file format (copy mode dependent).
• User profiles in software to control employee access.

As with previous models, the SD160PC SD Card Duplicator can read CID numbers of Secure Digital media. The CID number is a Card ID number written into read-only memory by the card manufacturer and read back through a hardware chip and vendor command on a host system such as the SD160PC. A card ID number is an extra layer of security for encrypted content written to Secure Digital media. Nexcopy displays the CID number of each card with the option to download and export said CID numbers to a .csv file.

Please visit the SD160PC product page to view details about the product including a live speed test (video) displaying the copy speed of SD card duplicator system.

The SD160PC is currently shipping and available for purchase from Nexcopy directly or through our global reseller channel of authorized resellers.

Nexcopy announced the SD Card Duplicator product release through PRLeap Press Service on March 30,2022

You’ve heard the quote “the devil is in the details” and when it comes to duplication of data to SD cards, nothing can be more true. Today we talk about an SD Card Duplicator which provides the ability to data stream unique content to each card.

Typically a user would duplicate the same content to SD cards because they intend to make many copies of the same content. However, my companies who use SD media (or microSD media) want to not only copy the same content to each card, but also copy unique data to each card.

Let us dig a little deeper with an example:

It is very common for companies who generate map data also want to protect their mapping information. Maps are expensive to make and often times hold proprietary information that company wants to protect. So when it comes time to use an SD Card Duplicator to make hundreds or thousands of copies, it is required to have a protection scheme included with the duplication solution.

A common method to provide protection on SD card media is using the CID number of the card. The CID number is a value which is put into “read only memory” of an SD card and that CID number is unique to each card and follows the card around. It is not possible to copy or duplicate the CID number… it is a value which is designed to only be read. In addition to the unique number, there takes specific vendor commands to read the CID number from the card itself.

With an SD Card Duplicator from Nexcopy it is possible read the CID number because Nexcopy uses the special vendor commands to read the CID value.

So this is what a mapping company can do:

• Encrypt the mapping data
• Include a text file with the decryption code for the maps
• Include the CID number of the physical card in the text file mentioned above
• Since CID numbers are unique to each card, write the unique key code text file to each card

With the SD Card Duplicator the user can export the CID numbers in bulk during the duplication process. When the CID numbers are exported in bulk, the company can write a script to generate key code text files which can only be decrypted by the card which holds the correct CID value.

The final step of the SD Card Duplicator would be writing the encrypted map data to all the SD cards (or microSD cards) and make a second duplication pass to perform the unique data stream of the encrypted file which holds the CID number and key code to each individual card.

There is certainly some custom scrips or batch files which the end-user would need to write, but the bulk of the duplicator process would be done by the Nexcopy SD Card Duplicator.

Secure Digital (SD) is a proprietary non-volatile memory card format created by the SD Association (SDA) for use in portable devices.

The standard was introduced in August 1999 as an improvement over MultiMediaCards (MMCs) by a collaboration of SanDisk, Panasonic (Matsushita), and Toshiba, and has since become the industry standard.

In January 2000, the companies also established the SD Association (SDA), a non-profit organization, to promote and develop SD Card standards.

This article explains how to encrypt data which can be decrypted on both a Mac and Windows computer.

Microsoft Windows accounts for nearly 80% of desktop computers, with Apple OS accounting for about 18% of the market share; (as of Q3, 2021) with this in mind, it is very common for users to want encrypted data to be shared on both Mac and Windows computers. For example, at work, Microsoft Windows is used, while at home, the employee uses a Mac computer. It is not easy to share encrypted data between these two operating systems. There is no installed solution from Microsoft or Apple that provides cross-platform encryption and decryption.

There are two options for those who want to decrypt files on both a Microsoft Windows and an Apple Mac computer.

Individual users can purchase software that encrypts and decrypts software for both Mac and Windows computers as one solution.

The other solution is buying a physical drive which supports decryption on either operating system.

The second option is better suited to a business. This is true because the employee or individual is not required to purchase software.

This article explains how to encrypt data which can be decrypted on both a Mac and Windows computer by using a specific USB flash drive.

The only known solution that has the following three characteristics in a product by Nexcopy. This is a company which provides feature rich flash drive duplicator solutions, but also provides advanced functions to flash drive, such as cross-platform encryption.

This is how the Nexcopy USB flash drive encryption solution works:

• PC based software is used to encrypt the data
• Included with the encrypted data are two software utilities loaded onto the flash drive
• The utilities run from the flash drive and decrypt the data when the correct password is entered
• The applications do not require installation, they run directly from the flash drive
• The PCViewer.exe is the Windows based utility – no admin rights required
• The MacViewer.app is the mac based utility – no admin rights required
• By launching the correct utility and entering correct password the files will be decrypted and displayed on the associated operating system

Please keep in mind there is a difference between the term “encryption” and the term “copy protection.” There is a difference.

The process of encoding information is known as encryption. This process converts the original representation of the information, for example, plaintext, into ciphertext. Only the authorized party who knows how to decipher the ciphertext back into plaintext can reorganize and piece it back together. The important thing to remember is that once the decipher is complete, the user can do whatever they want with the plaintext. That content can be copied, duplicated, shared, streamed, and screen captured by the user.

Copy protection includes the process of encoding; however, it adds an additional layer of security by prohibiting the user from doing anything other than viewing the content, such as copying, duplicating, sharing, streaming, and screen capture. To put it another way, the files can only be viewed and not modified.

Encryption is a valuable technology in situations where the content owner trusts the person with the password; however, security is required in the event that the USB flash drive is dropped, stolen, or misplaced. By encrypting the content, unauthorized users are prevented from accessing it.

Copy protection is a valuable technology for protecting content while allowing multiple users to view it. For example, a teacher may have valuable lessons that they want all students to see, but they do not want the lessons saved or shared with other classes. This is an excellent application for copy protection.

The company offers USB duplicator solutions for mass production of USB encrypted flash drives. Nexcopy also offers large-scale USB duplicators for copy-protected flash drives. So, depending on the individual or company’s needs, there is a solution for those who require encryption for both Windows and Mac computers.
