PNY XLR8 CS3140 Spec and Price in Canada
A Phison PS5018-E18 controller and onboard DRAM cache put the XLR8 CS3140 at the top of PNY's lineup, with PCIe 4.0 sequential speeds rated at 7,500/6,850 MB/s read/write. Endurance is rated to 1,400TB written on the 2TB model, backed by a five-year warranty — figures that put it in flagship gaming and creator-workstation territory rather than mainstream builds. Anyone loading large game libraries, working with 4K/8K media, or running scratch disks for heavy multitasking gets the headroom a DRAM-backed Gen4 controller provides.
14th of 106 models in the SSD catalog on Sequential read. 20th of 106 models in the SSD catalog on Sequential write.

What owners and reviewers say
Summarised from 3 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers found it a competent, consistent PCIe 4.0 performer with strong peak throughput and good power efficiency.
- It uses a Phison E18 controller with TLC NAND and a DRAM cache, and is a good PlayStation 5 option with the right heatsink.
- Owners report it works as described, with a DRAM cache and quick, responsive performance in always-on use.
- Owners considered it good value when bought on sale.
Commonly criticised
- It lacks anything to set it apart from a crowded field, and its pricing was not especially competitive.
- It runs hot without a heatsink, and a conservative SLC cache limits sustained write speed.
- A couple of owners find its speeds average and slower than the larger-capacity version.
