Expert's Rating
Pros
- Market-leading cost per gigabyte
- Very good performance until cache runs retired
Cons
- Sustained pen speed plummets after secondary cache is exhausted
- 500MB version writes half as fast every bit the 1TB
Our Verdict
This drive is identical affordable. Follow the 1TB version, whose execution is very good leave out during long writes (larger than about 4 percent of capacity). Not a drive for large information sets, but a enthusiastic deal for the average user.

I regularly end bargain TLC SSD reviews with the advice "Don't buy it unless it's much cheaper than the competition." Until Pivotal's P1, no drive ever met that criteria. But the 17 cents per GB that the 1TB version wish set you spinal column is a good 8 cents cheaper than all but of the competition. And, piece it's no blazing-fast Samsung 970 Pro, you don't give way up a ton of performance unless you regularly write 50GB (inferior with smaller capacities) or much. If you do, move along to another review.
Design and specs
The Important P1 is an x4 PCIE NVMe SSD that ships in the 2280 (22 millimetre broad-brimmed, 80 millimeter long-range) work factor. The drive comes in 500GB and 1TB flavors that retail for $90 and $170 respectively. That's a corking $80 cheaper than most of the competition presently. They carry a 5-year warranty and are rated for 100TBW (TeraBytes Written) for every 500GB of capacity.
Crucial The P1 looks pretty a lot the likes of whatsoever early 2280 NVMe/M.2 drive. It's just cheaper.
That's an extremely low TBW paygrad for an NVMe labor, but it's no doubt part of the intellect for the low price. The scuttlebutt roughly the industry is that TBW ratings are worst-caseful scenarios that are generally exceeded aside a large margin. And that's still 54GB per Clarence Shepard Day Jr. over the 5 years—more than most users are likely to write. And it is just writes—reading doesn't affect longevity.
Carrying out
Before I get to the results, please note that I tested the 1TB version of the drive. The 500MB edition which I did not test, patc cheaper, claims half the write carrying into action. That's a common phenomenon caused by having only half as many chips to spread the data crossways. It's as wel likely to make less cache and split up prey to the slow TLC writes rather. More than on that in a paragraph or two.
IDG asdfasdfas
The 1TB P1 actually passed totally our standard tests, including the 48GB copies with flying colours, though IT will never represent FALSE for a Samsung 970 Pro, or even a 970 EVO. I've included the SATA drive to show merely how much you'll gain simply by moving to NVMe from SATA. Keep that in mind with all our NVMe reviews: Even the slowest is faster than SATA away a healthy margin.
IDG Zero problem for the 1TB P1 when copying less than 50GB.
It was only during the 450GB spell test, which we on a regular basis run to see how things proceed when the cache runs out, that the driveway slowed down—tragically.
IDG A vainglorious problem when the 1TB P1 writes more than 50GB at one time.
By tragic, I'm talking roughly 95MBps, operating room much a 1000-percent drop, as you can see in the visualise above. Ouch.
IDG asdfas
For standard everyday use, with NVMe's stellar search times and flyspeck lodge performance, the P1 clay an great bargain because of the price. But it's not the drive for you if you regularly publish large amounts of information.
IDG Though hardly top-grade-of-breed, the P1's copy times were still reasonable, and ALIR better than the SATA drive we included for a engineering comparison.
It's the budget drive in
Price will out. The P1 is the first bargain SSD to it saves you enough money to forgive the episodic super-slow drop a line. If you want expedited sustained throughput when copying more than 50GB of data (or promising 25GB with the 500GB version), you'll require to spend leastways another $80 for WD's Sarcastic SN750 NVMe. Your choice.
This article was redaction on November 30th, 2019 to note that the P1's TBW ratings are selfsame, not reasonably stingy.
