Tom's Hardware reviewed the Kingston A1000 NVMe SSD
A quote from the article:
Kingston's A1000 entry-level NVMe SSD is slow enough to fit in that category, but the price is higher than it should be. The Phison PS5008-E8 SSD controller promised us low-cost and low-power devices that would speed the transition to NVMe. Early indicators backed that claim, but the market is different now than when companies first launched products with the controller. Kingston was a little late bringing the A1000 to market, and as a result, faces several challenges because mainstream NVMe SSDs like the Adata XPG SX8200 and HP EX920 have crashed the price points the A1000 was designed to fit in. The A1000 is a decent SSD, but the performance difference that comes with spending just a few dollars more is much larger than we imagined.Kingston A1000 NVMe SSD Review
