The PX series from the Polish brand GOODRAM comes out with affordable 2.5 format drives that combine high quality control, moderately high data exchange speeds and memory controllers that are good by the standards of the budget segment. As in the case of RAM from the Polish manufacturer, the target audience of the PX series are people looking for a simple, inexpensive and reliable solid-state drive that can replace an outdated hard drive or a regular SATA 3 SSD, the speed of which is noticeably inferior to NVMe drives. The main competitors of the PX series are drives from Kingston NV, WD Blue and Crucial P.


The PX series range is represented by models with capacities from 256 to 2000 GB. All variations use durable 3D TLC NAND flash memory and high-quality ICs that have undergone additional quality control. Thanks to the use of proven controllers from Silicon Motion, PX drives heat up slightly even under constant load and do not suffer much from speed drops when the cache memory is heavily loaded. In all cases, the manufacturer provides a three-year warranty.

As for the speed performance of the PX series, the version of the PCI-E data exchange interface plays a largely decisive role. In more conventional drives with PCI-E 3.0, linear read and write speeds are typically in the range from 950 MB/s to 2050 MB/s. For slightly more expensive and advanced drives with a PCI-E 4.0 interface, the minimum write speed is 1700 MB/s, while the read speed can reach 5000 MB/s. But the average IOPS indicator practically does not change from model to model and rarely goes beyond the 300 thousand mark.
