Kingston SSDNow UV400 240GB SSD Review


Kingston always takes special attention to low-cost SSD products, with a great price to capacity ratio. Last year Kingston released the UV300 SSD series, which was their low-cost budget friendly Solid-State Drive (SSD) with company’s first TLC NAND drive, but its custom LSI controller didn’t have a great performance. With new advancements in controller technologies and improvements in TLC NAND Flash, Kingston redesign and bring the UV400 series drives with much faster speed and higher capacities ranging up to 960GB. Kingston used the Marvell 88SS1074 SSD four-channel controller and 15nm 2D planar Triple-Level Cell (TLC) NAND flash memory to ensure great performance, with 550MB/s read and up to 500MB/s write speeds for sequential performance, and the maximum random 4K Read/Write speeds would be up to 90,000 and 50,000 IOPS.
