Because the number of layers has also increased, the bit capacity per wafer is said to be 40 percent higher, which is why more chips with the same memory quantity can be cut from one wafer. Through revised technology as well as improved manufacturing, the density of the cell arrays is said to have increased by 20 percent. However, BiCS5 is primarily a way to significantly reduce costs. Flash Forward also promises up to 50% faster interface speed compared to BiCS4, well. Flash Forward again relies on string stacking, so they simply combined two 56-layer arrays here. The old BiCS4 still has 96 layers, so the number of layers has only increased slightly in the BiCS5. And because it is so nicely compatible, you can also use the older BiCS5 as a provider of a rather cheap NVMe SSD. The Phison PS5019-E19T just described is compatible with a wide range of flash memory variants and supports modern NAND chips with 1200 MHz interface. Phison has also implemented SmartFlush, which enables fast cache recovery for predictable and consistent performance. The size of the dynamic pSLC cache, which I will also discuss in a moment, is therefore 1/3 of the available capacity of the TLC drive. Phison’s E18, like the E12S and E16 models, supports fully dynamic write caching. It even theoretically supports hardware-accelerated AES 128/256-bit encryption (which is TCG, Opal 2.0 and Pyrite compliant) and has a built-in crypto-erase feature, but the SSD does not advertise this. It also leverages the fourth-generation LDPC ECC engine, SmartECC (RAID ECC), and end-to-end data path protection for robust error correction and improved data reliability. This can also be seen in the fact that, unlike the older models like the E16, you can do without an integrated nickel heat sink. Thermal throttling is implemented, but is of no further concern since the controller does not get too hot in most applications. Like other controllers, it uses Active State Power Management (ASPM), Autonomous Power State Transition (APST) and L1.2 ultra-low power state. Thus, it supports both Trim and S.M.A.R.T. Phison’s PS5018-E18 complies with the NVMe 1.4 specification and has a number of common features. These are two 2 GB CMOS Double Data Rate IV (DDR4 3200) Synchronous DRAM. The EXCERIA PRO’s design also uses a DRAM-based architecture, with two DDR4 chips from SK Hynix. The SSD contains four NAND modules on the top, thanks to the small size of the controller, which measures only 12 x 12 mm. This is then also the point that I meant at the beginning by contradiction. However, you can see the bottleneck here, since BiCS5 can only deliver 1,066 MT/s and the controller cannot be nearly maxed out with that. The controller communicates with the NAND via eight NAND flash channels at up to 1,600 MTps and supports capacities of up to 8 TB with 32 chip enable. To realize this, Phison has included five Arm Cortex R5 CPU cores, three of which act as the primary cores for the main tasks, while the other two are clocked lower for the Dual CoXProcessor 2.0 code to act as a more economical tandem to take at least some of the load off the three main cores. It is, in terms of features and performance, a very interesting and fast PCIe 4.0 x4 SSD controller. This was developed from scratch by Phison at the time and is manufactured in TSMC’s 12 nm node. The controller used has been labeled as an OEM product from Phison on KIOXIA, but it actually hides the well-known PS5018-E18 behind it. But first things first, let’s start with the controller. And what do we see now? You can see the memory, the controller and the DRAM modules. Once you have removed the labels, you can see the PCB, which this time does not come from TECHVEST, but was most likely manufactured by TECHVEST itself, because the corresponding UL entry on the PCB is missing and only the label refers to KIOXIA. I had already written that the SSD gets a bit hotter since the older NAND has a higher power consumption and the heat dissipation should be really good.
