  • CS3140 1TB CDM

As the development of the PCIe Gen 4×4 controller matures, we are getting ridiculous read/write speed claims on the marketing material. Some of you may not have noticed but there are plenty of high-end PCIe Gen 4×4 SSDs being marketed with over 7000MBps read speeds, in this case, 7500MBps. That is, the theoretical peak read speed except that we are being limited by our setup at the 7000MBps range.

ATTO Disk Benchmark


ATTO shows a better picture of the IO size that is favourable for the CS3140 4TB:

  • 128KB~64MB for Writing
  • 256KB~64MB for Reading

The same applies to the 2TB drive.


The 1TB drive has a different tier of performance due to the use of fewer NAND chips.


CS3140 temp

“With great speed comes great heat”

Without an SSD heatsink, the CS3140 quickly thermal throttles during our burn test, with a recorded peak temperature of 79C.

Since this SSD is being sold with or without a heatsink, you will need to reevaluate your motherboard’s SSD cooling and determine if you need the additional cooling solution or not.


The PNY XLR8 Gaming CS3140 has certainly lived up to our expectations as a high-end PCIe Gen 4×4 SSD with a competitive price tag:

  • 4TB – RM1,689 (price per gigabyte RM0.422)
  • 2TB – RM639 (price per gigabyte RM0.3195)
  • 1TB – RM359 (price per gigabyte RM0.36)

Most of the SSDs of this performance would be priced near RM400 for the 1TB variant. Of course, there are plenty of affordable choices available, especially the ones without a DRAM cache. That is when you don’t mind the lack of it. For example, the purpose is as simple as game storage. The CS3140, on the other hand, is excellent for all purposes, including as a boot drive or even as a perfect replacement drive for the PS5.

Worth mentioning is the warranty as PNY offers a 5 years warranty for all CS3140 models. As long as your product packaging contains the sticker, you may contact Fusion Tech Supply Sdn Bhd (Malaysia distributor) or PNY’s Malaysia Facebook Page for any product or warranty-related enquiries.
