Which is better for a gaming PC upgrade?

The Silicon Power P34A60. It gives 1TB and faster writes, which matter more for game installs and updates than the SN530's small read edge.

Neither listing gives a terabytes-written rating, so endurance can't be compared directly. The Silicon Power lists LDPC and end-to-end data protection; the WD SN530 lists none of these.

Is the WD SN530 worth it over the Silicon Power?

Only if you need the 2230 size or lower power draw. Otherwise the Silicon Power offers double the capacity and faster writes for a known $152.97 at Amazon as of November 6, 2026.

Will the Silicon Power fit a laptop?

Yes, if the laptop takes a full-length 2280 M.2 drive. Check the slot length first, since the SN530's 2230 size fits tighter spaces.

The SN530 reads slightly faster at 2,400 MB/s versus 2,200 MB/s. The Silicon Power writes much faster at 1,600 MB/s versus 950 MB/s.

Does the Silicon Power have a DRAM cache?

No. It is DRAM-less and uses host memory buffer instead. The WD SN530 lists a 256 MB cache.
