Silicon Power S55 TLC 120GB and 240GB SSD Review

Storage/SSD by stefan @ 2016-06-23

The S55 TLC series of SSDs from Silicon Power are offering quite a bit of storage space at acceptable performance levels unless the buffer gets filled; if we are used to transferring frequently large batches of files to the drive, the speed will decrease to a minimum of about 95MB/s (regular HDD performance levels), but we will still benefit from very good access times.

After dismantling the chassis, we will end up checking out the back side of the PCB, which does lack the TLC NAND Flash chips (they are present on the 240GB version):

 

 

 

The 2/3-sized PCB comes on the front with the PHISON controller, RAM buffer but also four TLC NAND chips:

 

 

 

The NAND modules are practically Toshiba 15nm TLC:

 

 

 

The PHISON PS3110-S10C-12 is the smaller variant of the PS3110-S10-X of their S10 controller and features only four NAND channels instead of eight; this one is used on smaller capacity SSDs. However, the 240GB variant of the S55 comes with the fully-fledged S10-X controller:

 

 

 

Both 120GB and 240GB variants feature a 256MB NT5CC128M16IP-DI IC IC from Nanya, which is specced DDR3L-1600 with 11-11-11 timings:
