'Crucial P2 NVMe M.2 SSD Arrives With Boosted Performance' - Tom's

While the P1 was available in 500GB and 1TB capacities, the P2 is only listed in 250GB and 500GB variants. However, the P2 boasts improved performance over its predecessor.

The 250GB model delivers sequential read and write speeds up to 2,100 MBps and 1,150 MBps, respectively. The 500GB model, on the other hand, is capable of hitting sequential reads up to 2,300 MBps and sequential writes up to 940 MBps. Crucial didn't list the random performance for the P2.

I'm shocked how far Crucial is compared to their competitor's NVMe drives (both in speed and drive capacity).

I would think they would partner with one of the companies who they sell NAND to, and release a truly competitive product. Now I understand the "real world" difference argument, but I would imagine many people would go with a drive that advertises a lot better specs (WD, Samsung, Adata, Silicon Power, Sabrent, Seagate, or even other QVL drives like the Intel 665P).

Yeah, that's kind of pathetic write performance, 940MB/sec? And no 1TB model? That's an automatic NO from me. 1TB minimum from now on, for primary / OS storage NVMe devices.

Nobody finds it interesting that smaller SSD has better write performance, than bigger one?

What's really odd about that, is the 500GB version has slower sequential writes than the 250GB version.

But yeah, no 1TB option in today's market is very odd. I understand not offering 2TB options, but having a 1TB option should almost be a given in 2020.

My assumption is a TLC/QLC split but I'm waiting to find out more. If so, the P1 is meant to fill the 1/2TB space, which makes sense given the 665p (for example) omitted the 512GB SKU that the 660p had. (larger P2 SKUs are possible in the future, although keep in mind the P2 is listed using Micron 3D NAND while the 665p is using Intel's specific 96L QLC)

If you compare the 96L TLC Kingston A2000 at 240GB, 1100 MB/s, and the 64L QLC 660p at 512GB, 1000 MB/s, you see this pattern on two drives using the same controller (SM2263).
