Patriot Viper VP4300 Lite 1TB M.2 PCIe Gen4 x4 Gaming SSD Review

Storage/SSD by stefan @ 2024-05-12

The MaxioTech MAP1602A along with YMTC Xtacking 3.0 NAND combo performs well even when dealing with lower capacity drives as the Patriot Viper VP4300 Lite 1TB, succeeding write rates over 900MB/s even when the pSLC cache has been fully filled. It makes use of HBM instead of DRAM caching, while the heatspreader does help with heat evacuation to permit operation in environments with less than ideal airflow, such as the PS5.

Drive Behavior during Continuous Write

Before starting the second stage of our tests, we needed to fill the drive over 50%; during this time, we have also monitored the transfer rates in order to check when the pSLC cache gets filled and how the drive behaves afterwards. As with any drives with MaxioTech controllers, we do get readings from two separate temperature sensors:

The write speeds started at optimal levels:

The operating temperature remained within safe margins:

A small speed drop occurred after writing about 92GB:

A sharp drop was noted after having about 153GB of data written, but did not go under 900MB/s, which is good for a mainstream drive:

The temperature remained within a decent range, not causing the drive to throttle:

Surprisingly, the transfer rate has recovered quite quickly, so we could also note spikes of up to 1.5GB/s:

At the end of the workload, the NAND ICs got to about 50 degrees Celsius, while the controller got a bit hot at about 68 degrees, but we did not note sharp decreases in performance due to possible throttling:
