Review on Hikvision 1TB M.2 SSD HS-SSD-E3000/1024G by Jnis Staulis ᠌

Not everything is so rosy with this 1TB drive. A disk bought in NIKS, through the Market here, with a volume of 1 TB 5 days ago already had "on board" not 4 memory chips, as many here in the reviews, but two, each with a larger capacity, as on a 2 TB model. Hence, the write speed in CrystalDiskMark is about 2022 mb/s, and the linear write in AIDA64 of the first 15% of the disk (cache with two 150 GB chips comes out) is about 1800 mb/s, then up to 80% of the disk is about 650 mb/s (almost twice less than here in the reviews) and the last 20% of the disk drops to about 220 mb / s. Those. speeds are approximately the same as on the 500 GB disk version, where there are also two chips. Linear recording in AIDA in time took 44 minutes 52 seconds (for comparison, here in the reviews 24 minutes 33 seconds, i. E. almost twice as long). Here in the reviews they mentioned the firmware from September, I have it from November 23, most likely mine was produced later and it looks like they started to solder two chips on the 1 TB model now, which means that with this option only the 2 TB version will be able to produce the speeds declared by the manufacturer. I was sure that the 1 TB version would definitely have 4 memory chips, after looking at all the reviews with tests, screenshots with info on the memory and the controller, where all the channels of the controller for 4 chips (CH4CE4) are involved, but when I opened the package at home and took out the disk, then I immediately realized that the declared speeds could not be seen as my own ears. As always, Chinese roulette. Whoever wants to get the speeds declared by the manufacturer and here in the reviews, keep in mind that on the 1 TB version, until you open the package and take out the disk, you will not know which option you will come across. If there are two chips, then alas .
