Manufacturer description
The Kingston SSDNow V300 120GB is the drive you drop into an aging laptop or desktop when the goal is responsiveness, not raw capacity. It runs on SATA Rev. 3.0 (6Gb/s) with backward compatibility to SATA Rev. 2.0, so it works in older systems that never shipped with a 6Gb/s controller. Kingston rates this 120GB model at 180MB/s read and 133MB/s write, and positions it as roughly 10x faster than a 7200RPM mechanical hard drive based on the PCMark Vantage Advanced Edition HDD test suite. Because there are no moving parts, it sidesteps the head-crash and spindle failures that eventually take…
SpecPicks Verdict
SpecPicks scored Kingston Digital 120GB SSDNow V300 SATA 3 2.5 Solid State Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Kingston's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Will this fit my older laptop that has a 9.5mm drive bay?
Yes. The drive itself is a 7mm 2.5-inch unit, and Kingston includes a plastic adapter that shims it to 9.5mm for older bays.
Does it work if my motherboard only has SATA 2 ports?
Yes. It is a SATA Rev. 3.0 (6Gb/s) drive with backward compatibility to SATA Rev. 2.0, so it runs on older controllers at that port's speed.
How much faster is this than my current hard drive?
Kingston cites roughly 10x faster than a 7200RPM hard drive based on the PCMark Vantage Advanced Edition HDD test suite. The 120GB model is rated at 180MB/s read, 133MB/s write.
Is 120GB enough space?
It fits Windows plus core applications comfortably, but not a large game or media library. Most buyers pair it as a boot drive with an existing hard drive for bulk storage.
What warranty does Kingston provide?
Kingston lists free technical support with this drive. Check the current product listing for the exact warranty term, as it varies by region and revision.
