In this article we will revisit the P34A80 mainstream SSD from Silicon Power, but this time in the more attractive, 1TB format. The product is shipped in a similar cardboard enclosure with a plastic window, so the potential customer can take a look at the drive, without the need of unsealing the box:
Some more details such as the supported bus, voltage, company info is available on the back side:
The inside contents are composed only of a transparent plastic mold, in which the drive is held securely:
The frontal PCB side does contain a large sticker that also acts as a heatsink; here we will find info regarding the internal code name, serial number and storage capacity:
On the back side of the drive, we will find two NAND ICs, but also some RAM cache; we will get back to these later:
After the removal of the large top sticker, we can take a look at the rest of the components:
Instead of using Nanya RAM ICs, the 1TB version packs SKhynix H5AN4G8NBJR 512MB caching RAM ICs:
The central controller is the same 8-channel Phison PS5012-E12-27 that does support QLC, 3D TLC NAND and PCI-Express 3.0 x4 interfaces:
The TLC 3D NAND flash is manufactured by Toshiba, using 64 layers on a 15nm manufacturing process; this drive comes with a total of 25GB of SLC cache, which provides quite a bit of boost during normal operating conditions; the product code name is the same as on the 512GB drive variant:
The same SKhynix H5AN4G8NBJR 512MB IC is present on the opposite side of the PCB as well, for a total of 1GB:
The last two NAND ICs on the back do bring the total storage capacity to 1TB:
