Affordable and powerful 512GB PCI-E Gen3 x4 (NVMe v1.3) M.2 SSD. It is positioned as a product of the middle price category, designed for balanced configurations of consumer PCs, low-cost gaming / workstations and laptops. It has a frameless design and compact dimensions corresponding to the 2280 form factor. The key component of the GOODRAM PX500 SSDPR-PX500-512-80 SSD is the time-tested 4-channel Silicon Motion SM2263XT controller.
It does not have its own DRAM buffer, but thanks to HBM (Host Memory Buffer) technology, it is able to use part of the system memory for these purposes. It demonstrates a decent level of I / O performance and high read / write speed (2000/1600 MB / s within a dynamic SLC buffer up to 64 GB). It is worth noting that only Windows 10 provides full support for HBM technology, and older versions of this operating system can experience an almost twofold decrease in performance. 64-layer TLC 3D NAND flash memory is used to store user data. The drive provides impressively fast loading of the operating system, resource-intensive professional applications and the latest games. It is also worth mentioning the complete silence and low power consumption, which is fundamentally important for the battery life of the laptop.

Progress on the face
Goodram PX500 is a low-cost M.2 PCI-E 3.0 solid state drive, which, nevertheless, demonstrates speed characteristics at the level of pre-flagship models of previous years. So, the 512 GB version has sequential read and write speeds of 2000 and 1600 MB / s, respectively (the 1 TB version is even faster).
Purchase for years
Random reading and writing of small 4K blocks is 173 and 140K IOPS (read and write operations per second). The guaranteed resource of rewriting is claimed as much as 330 TB. Moreover, this is rather a theoretical limitation, but in fact the disk will continue to work properly.
European product
The heart of the Goodram PX500, the brainchild of the Polish company Wilk Elektronik, is the Silicon Motion SM2263XT controller. The XT index means the absence of an operational buffer both in the controller itself and on the drive's printed circuit board. Instead, Host Memory Buffer technology is implemented, which uses part of the system-wide RAM.
No overheating
Dual-channel 128-bit DDR4 is substantially faster than 16-bit DDR3L, which is typically used as native SSD cache. So it turns out not only savings on the cost of the disk, but also an increase in performance. The Goodram PX500 heats up relatively weakly, so even a thin bundled heatsink can handle the cooling.
