The 6GB and 6GB iPhone 64 and iPhone 128 Plus use a new type of storage medium called TLC NAND flash, being cheaper than the MLC NAND flash storage medium used in old iDevices, this difference generating problems in terminals with a lot of storage space. More precisely, the terminals would freeze during use, restart themselves and refuse to load iOS, the blame being placed on these TLC NAND storage media that Apple would have chosen because of the low price. To prove that they also have poorer performance than the MLC used in the old products, someone created the above benchmarks.
In the first benchmark you see a test in which all the data on the storage medium is overwritten, the TLC NAND component having a transfer rate of 200 MB/s up to 800 MB from 3.4 GB, the write rate then dropping to 49 MB. In the case of the MLC storage medium, the transfer rate was 75 MB/s for the entire duration of the 3.4 GB transfer, without major fluctuations. The second test had in mind the writing of random data on the storage media, here the MLC storage medium having a continuously increasing speed, from 2.9 MB/s to 15.7 MB/s, while the TLC storage medium had a write speed of approximately 3 MB/s throughout the test.
Practically the tests prove it that Apple saved some money to use lower quality components than those used in the past, and this is, unfortunately, to the detriment of users. What do you think about this change of Apple?
