PNY 1TB CS3150 Storage Drive

ZDNET’s key takeaways

PNY 1TB CS3150 M.2 storage drive, available for around $170.
Overall, it’s a fast M.2 drive with active cooling to keep running temperatures below the maximum rated temperature.
The heatsink makes the drive rather bulky, and you will need a 4-pin fan header on the motherboard to power the fans.

In the not-so-distant past, the solution for boosting the speed of an aging, sluggish PC was to add more RAM or upgrade the processor. Now, the way to sail over that speed bump is to get a new storage drive, and there’s no better storage upgrade for performance than fitting your system with an M.2 drive.

There is no shortage of excellent M.2 drives out there, but if you’re looking for high-end performance and stability when the going gets tough, the CS3150 by PNY is well worth a look.

What makes this drive special? Not only does it have a heatsink, but that heatsink is kitted out with two fans to dissipate the heat generated during use.

How do you know if your system can take an M.2 drive? Check the manual for your system or the motherboard it uses, do an online search, or open it up and check for an M.2 drive slot.

One of the biggest killers of storage drives is heat. While this isn’t a problem for most systems, high-end gaming and content creation systems — when pushed to their limits — might hit a point where thermal throttling occurs (that is, a deliberate slowing down of the system to allow it to cool down) — or the heat might cause crashes or premature damage to the drive.

The faster the drive, the more waste heat it generates.

And the CS3150 is a fast drive. Clocking sequential read and write speeds of 11,500 and 8,500 MB/s, respectively, it’s not as fast — or as expensive — as the Crucial T705, but that drive doesn’t have an actively cooled heatsink.

Testing the CS3150, I got speeds within 5% of the specs provided by PNY, which is more than acceptable.

If you want to get the best out of this drive, note that you’ll need at minimum an Intel Core 13th or 14th-gen or AMD Ryzen 7000 CPU on a compatible motherboard with a free Gen5 M.2 slot.

As for heat, I stress-tested the drive using CrystalDiskMark and monitored the temperatures using CrystalDiskInfo, and — despite my relentless thrashing of the CS3150 — I could not get the temperatures to exceed the 70°C/158°F maximum operating temperatures. It would seem that the active cooling is doing its job.

It’s worth bearing in mind that heatsinks and fans move heat from the drive to the outside air; therefore — to maintain the drive’s efficiency — you also need to ensure the PC has adequate airflow through the system. Also, the built-in fans on this device require a free set of 4-pin fan header pins on the motherboard to work.

The cooler is very beefy but can be removed.

This is quite a bulky drive. Although it should fit most M.2 drive slots on PC motherboards, it won’t fit in external drive enclosures unless you remove the heatsink with a screwdriver. This isn’t typically recommended, but if you plan to do it, be careful when separating the aluminum heatsink from the drive’s circuit board, as you don’t want to rip chips off the board.

Need a bit of color in your system? There’s also a version of this drive with RGB lights built into the heatsink.

ZDNET’s buying advice

I can’t fault this drive. It’s a solid, fast, well-made drive that takes cooling to the next level with active cooling for when the drive is pushed hard.

While the PNY CS3051 isn’t the fastest drive around, the read and write speeds are good enough to keep all but the most performance-hungry users happy.
