Silicon Power Extreme E25 128GB Review


Getting a sense of deja vu here? You should if you read our Patriot Torqx 2 Review, as the PCB layout looks very familiar:


The same Phison PS3105-S5 controller is present in the E25, which uses a 32-bit ARC 600 processor that needs to be paired to its own RAM buffer, as illustrated by the DDR2 512MB Nanya DRAM cache buffer to its side (NT6DM16M32AC). In addition, the Phison PS3105-S5 SSD controller offers native TRIM garbage collection, Native Command Queuing (NCQ), and the S.M.A.R.T. command set.


The Phison controller also manages eight channels and supports NAND flash chips in both SLC and MLC configurations; in this case, the eight 32nm Toshiba TC58NVG6D2GTA08 16GB MLC NAND flash modules.

Having an eight-month gap over the Torqx 2, the question is whether or not Silicon Power fine-tuned their E25 to achieve better results utilizing the Phison PS3105-S5 chip. Certainly picking the Nanya DRAM buffer over the Hynix buffer, and updated Toshiba NAND chips should yield maximum results to a SATA 3Gbps drive of this caliber, as many drives utilizing Phison tend to go with the Nanya and Toshiba configuration.

    This SSD is on German markt for around 70€ to have, its even cheaper than crucial v4 (85€) for the same capacity. The benchmark numbers look nice, especial the low QD 4k read/write ones.

    Here is the link:

    I think, its quite competive to crucial v4 using the same PHISON controller. E25’s hardware ist alot better: 32nm toshiba nand vs 25nm micron, 512MB DDR2 Cache vs 128MB DDR of Crucial v4
