REVIEWS CRUCIAL P1 NVME SSD

more than a 1000-percent drop, as you can

see in the image above. Ouch.

For normal everyday use, with NVMe’s

stellar seek times and small file performance,

the P1 remains an great bargain because of

the price. But it’s not the drive for you if you

regularly write large amounts of data.

BOTTOM LINE

Price will out. The P1 is the first bargain SSD to

that saves you enough money to forgive the

occasional super-slow write. If you want fast

sustained throughput when copying more

than 50GB of data (or likely 25GB with the

500GB version), you’ll need to spend at least

another $80 for WD’s Black SN750 NVMe

(go.pcworld.com/sn75). Your choice.

Though hardly best-of-breed, the P1’s copy times were still reasonable, and far better than the SATA drive

we included for a technology comparison.
