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.

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.

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.
