Which is faster, the P34A60 or the SN5100?

The SN5100. Its rated 7,100 MB/s read and 6,700 MB/s write are more than three times the P34A60's 2,200/1,600 MB/s, and it adds published random speeds of 1,000K/1,300K IOPS.

Is the SN5100 worth the extra $18?

Yes if your board has PCIe 4.0 and you move large files or run heavy workloads. If you only browse, game and do office work on a Gen3 slot, the P34A60 saves money without a noticeable difference.

The SN5100 has a published 600 TBW endurance rating; Silicon Power does not publish one for the P34A60. The SN5100 also uses QLC NAND, so its endurance rating matters more, but 600 TBW is fine for normal desktop use.

Will the P34A60 work in a PCIe 4.0 laptop?

Yes. It is backward and forward compatible in an M.2 2280 slot, but it will run at Gen3 speeds, so you would not get the SN5100's speed advantage from it.

The P34A60 is a Gen3 DRAM-less drive rated for low heat with no heatsink needed. The SN5100 draws 3.9 W active, so it benefits from a motherboard heatsink under sustained load.

Which is better for a PS5 or a fast desktop?

The SN5100. Its PCIe 4.0 interface and 7,100 MB/s read meet the speed class fast systems expect, while the P34A60's Gen3 speeds suit older machines and secondary storage.

Silicon Power P34A60 1TB NVMe SSD vs WD Blue SN5100 1TB SSD

Buy the WD Blue SN5100 if speed matters: it is roughly three times faster on paper (7,100/6,700 MB/s vs 2,200/1,600 MB/s) and runs on PCIe 4.0. Buy the Silicon Power P34A60 if you want the cheapest 1TB NVMe drive or your laptop only has a Gen3 slot. On November 6, 2026 the SN5100's best new price was $170.99 at AAAWave and the P34A60's was $152.97 at Amazon, a gap of about $18.

Today the Silicon Power P34A60 1TB NVMe SSD costs $18.02 less at its best price.
