Hard drive replacement
Solid-state drives are the next evolution of PC storage and run faster, quieter and cooler than the aging technology inside hard drives. With no moving parts, SSDs are also more durable and more reliable than hard drives.

For desktops and notebooks
Kingston solid-state drives will make your system more responsive so it boots quicker, loads applications faster and shuts down faster. They’re available in upgrade kits that include software to clone your files and OS in minutes.

Revive older systems
Solid-state drives will not only increase performance but can also be used to breathe new life into older systems. Choosing an SSD can save you the cost of buying a new PC by reviving the system you already own.

Kingston SSDNow UV400 SSD Review

The UV400 series started out as a RIM project, meaning Kingston sold it in Russia, India, and Mexico. Shoppers that are looking for extreme value dominate these markets. After mastering the RIM, Kingston has taken the UV series global. Like the V series that predates the updated models, this product should become an excellent seller and will also use a variable list of build materials. The UV400 480GB we are testing may not be the same design a month, year or two years from now. Internally, the drives may (and most likely will) change over time.

Kingston will release a UV400 960GB model soon. Until then, the series consists of three capacities that range from 120GB to 480GB. There are two product numbers for each capacity. The first is a drive-only blister pack. As the name suggests, it includes just the drive. The second product number belongs to a full upgrade kit that costs a little more, but you get a handful of useful accessories.

The UV400’s performance rises with each capacity increase. All three shipping products feature sequential read performance that tops out at 550 MB/s. The 120GB drive has the lowest write performance with just 350 MB/s. That shoots up to 490 MB/s (240GB) and 500 MB/s (480GB). The random performance scales the same way, with a base of up to 90,000 IOPS for reads. The random writes start out at 15,000 IOPS (120GB) and move to 25,000 (240GB) and finally 35,000 IOPS (480GB). The low random write performance leads us to believe the current UV400 models are shipping with asynchronous flash. With prices this low we can truly start to compare SSDs to hard disk drives. Impressive random write performance for a hard drive is 200 IOPS, so it’s obvious the UV400 has a big advantage.

The Marvell 88SS1074 “Dean” controller is at the heart of the UV400, and Kingston paired it with DDR3 DRAM to cache the flash translation layer. Kingston has a reputation for mixing and matching various components after it launches a new series, but you don’t have to worry about that as much with the UV400. This is already one of the least desirable component combinations using modern hardware that you can buy. The only step down from this point is a DRAM-less design. Thankfully, JMicron’s SSD controller business has moved on, so there really isn’t a step backward. Kingston wouldn’t even try to pass off a DRAM-less part as a UV400, at least we hope not. – Tom’s Hardware original –,4730.html
