Price (RRP): $about 300
The Crucial P1 1TB PCIe NVMe M.2 SSD is an ideal upgrade for any device that has an M.2 22×80 slot that supports PCIe NVMe – not the slower SATA6 interface.
At below $300 for 1TB it is not too far a stretch to gain huge, huge I tell you, increases over hard disks and SATA 6 SSDs.
For example, a hard disk can at best do sequential read/writes of 150/130MBps. A SATA 6 SSD may get to 550/550MBps. In real life use, you can expect to achieve less than half that speed because traffic to and from the disks is half-duplex (can’t read and write at the same time). Plus, they die when read/writing larger files – down to a MBps or so.
PCIe NVMe SSD tops out at a blistering 2500/1000MBps, and it can read and write simultaneously using two or four PCI Express lanes. In reality, actual performance is a little lower.
Review: Crucial P1 1TB PCIe NVMe M.2 SSD
GadgetGuy likes Crucial gear particularly for its lack of ‘marketing hype”. You can rely on the company for accurate performance specifications and fair prices. We also like that knowledgeable computer specialists, and online stores like MWave and Skycomp sell it.
What is a Crucial P1 1TB PCIe NVMe M.2 SSD?
PCIe means it communicates with the CPU over a high-speed PCI express bus. Crucial P1 uses four lanes for full-duplex and maximum speed.
NVM means non-volatile memory – it does not lose data when the power is off.
e means the new Express 1.3 standard which is faster than the previous 1.2 and seems to be able to handle larger file transfers faster.
M.2 is the slot. If it has one index notch, it is PCIe NVMe. If it has two,it is SATA 6. The two are not interchangeable. If you only have SATA 6 Crucial has the MX-500 M2 in 250/500GB and 1TB
Crucial P1 rates at 2000/1700MBps. Our tests using an Intel Hades Canyon NUC (GadgetGuy review here) easily achieved the rated speeds. PASS
It also did extremely well with random read/write of larger file sizes. The table below shows (in order from top down) 1, 8, 16, and 32GB files. PASS
SSD is reliable, more so than hard disks although the latter usually show signs of deterioration and you can replace before they die.
In my experience, no hard drive over five years old is to be trusted. SSD’s have diagnostic software that measures read/writes (Total Bytes Written) for their lifespan.
