Galaxy S23 128GB version may only support UFS 3.1

According to previous reports, Samsung announced that the Galaxy Unpack 2023 event will be held at 10 a.m. Pacific Standard Time on February 1, 2023. Before the official release, a lot of information about the Galaxy S23 series phones has been leaked. Recently, UniverseIce revealed that the 128GB storage model in the Galaxy S23 series phones does not support UFS 4.0, only UFS 3.1.

Judging from the previously leaked partial configuration comparison charts of the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra, only the Galaxy S23 has a 128GB storage model. Both the Galaxy S23+ and the Galaxy S23 Ultra have a starting capacity of 256GB, and the Galaxy S23 Ultra can be equipped with up to 1TB of storage. The memory capacity of Galaxy S23 and Galaxy S23+ is only available in the 8GB version, and Galaxy S23 Ultra is available in 12GB.

Previously, UniverseIce said that the Galaxy S23 series phones are equipped with LPDDR5X memory and UFS 4.0 flash memory. UniverseIce said that only Kioxia produced 128GB of UFS 4.0 flash memory, but Samsung did not, and the performance of 128GB of UFS 4.0 flash memory did not reach the normal level of UFS 4.0 flash memory. However, Samsung uses UFS 3.1 flash memory in the Galaxy S23 128GB version.

The full name of UFS is Universal Flash Storage. It is a flash memory storage specification designed for consumer electronics such as digital cameras and smartphones. It is developed by the JEDEC Solid State Technology Association. The biggest difference between UFS and eMMC is that the parallel signal is changed to a serial signal, which can better increase the frequency.
UFS 1.0 was launched in February 2011, with a maximum transmission rate of 300MB/s, and has been continuously updated since then; the UFS 3.1 standard was released in January 2020, with a maximum transfer rate of 2900MB/s; the UFS 4.0 standard will be released in August 2022, with a maximum transfer rate of 5800MB/s.
