Memory has been a growing priority when consumers shop for new mobile and tablet devices. So lets dig something deep in memory and find whats actually works inside it.
To begin with let’s elaborate on some basics.
Internal storage
Internal Nand Flash storage is the default amount of storage your OEM provides. As most of you must know, it is preceded by a number, say 8GB, 16GB or 32GB, which is misleading. A part of the storage is reserved for OS, system apps and pre-loaded apps and what is actually free at user end is at least 3 to 4 GB lesser than what is advertised.
Besides quantity, the quality of internal storage matters a lot. This is what I want to discuss here
To overcome the shortcomings of the eMMC chips , Samsung introduced UFS storage to smartphones with Samsung Galaxy S6/ S6 Edge.
Overall, UFS 3.0 storage could almost double data bandwidth while consuming lesser power. These storages can also withstand higher temperature range (-40°C to 105°C) which makes them more suitable for automotive applications.
Another important UFS 3.0 feature is support for multiple RPMBs (replay protected memory block) with multiple RPMB keys. RPMBs are hardware partitions used for securely storing critical data like user billing information, DRM content protection keys, etc. RPMB regions are fixed at manufacturing and are also configurable at manufacturing.

eMMc
eMMC stands for "embedded MultiMediaCard" and it's essentially a type of internal storage embedded or attached to a device or phone's motherboard. These chips are comprised of a controller and NAND flash memory, both of which are within "a single integrated circuit."This circuit connects to a given device's main circuit board. From there, the eMMC chip's controller is able to handle the task of putting data in storage. The use of NAND flash memory in an eMMC chip also uses little to no power to hold onto data.

Your eMMC storage performance degrades with time, as you keep filling it. To avoid performance penalty, it is advised that you keep about 20 percent of your storage free at all times.
Samsung eMMC memory is extremely compact, typically smaller than a postage stamp, allowing for smaller and thinner devices. Leading manufacturers have favorited Samsung’s eMMC memory because it allows for a smooth pathway to elegant and advanced mobile designs with a short time to market. The latest standard, eMMC 5.1, even furthered the performance and power efficiency.
To overcome the shortcomings of the eMMC chips , Samsung introduced UFS storage to smartphones with Samsung Galaxy S6/ S6 Edge.
On 7 July 2016, Samsung introduced the first UFS cards in 32, 64, 128, and 256 GB storage capacities.[20][21] The cards are based on the UFS 1.0 Card Extension Standard..
Note -Google Pixel 3a/3a XL still use eMMC storage
What is UFS ?
UFS was primarily designed to deliver SSD-like speeds on mobile devices. The first-gen UFS modules offered three times faster file copying times, as well as vast improvements in multitasking over eMMC modules. UFS is able to do this as it is a full duplex standard, meaning it can read and write data simultaneously. By contrast, eMMC can only read or write data at any given time.

Different versions of UFS
Another important UFS 3.0 feature is support for multiple RPMBs (replay protected memory block) with multiple RPMB keys. RPMBs are hardware partitions used for securely storing critical data like user billing information, DRM content protection keys, etc. RPMB regions are fixed at manufacturing and are also configurable at manufacturing.
Samsung Galaxy Fold was the first phone to have ufs 3.0 version but its launch was delayed due to some reason so One plus 7 and 7 pro were the first to launch UFS 3.0 in market.
Then Samsung put UFS 3.0 in Note 10.
What you need to know
- Early benchmark results have revealed the UFS 3.0 storage on the Galaxy Note 10 is faster than the OnePlus 7 Pro and Samsung Galaxy Fold.
- The higher performance can be attributed to the switch to F2FS file system from EXT4 on previous Samsung smartphones.
- When compared to the Galaxy S10 series, the performance differential is significant.
Samsung is constantly innovating NAND Flash technology, and is working to build industry-leading products that provide the highest level of performance and quality.
So guys please tell me if my post make you known to some unknown things.
Second what you think about Samsung's contribution in making storage industry more useful and fast.
