The Good The Plextor M7V is speedy, affordable and can handle years of constant data writing.

The Bad The drive is a tad slower than its predecessor and doesn't include any accessories.

The Bottom Line The Plextor M7V is a budget solid-state drive that's designed to last and will give any computer that still uses a traditional hard drive a big performance boost.

The M7V is the successor to the M6V and is Plextor's new value-priced solid-state drive (SSD). At launch the M7V has a low suggested price of $50, $71 and $146 for 128GB, 256GB and 512GB, respectively (actual street price will likely be lower). In return, its performance was slightly slower than the M6V. Still, the drive does what it's designed to do: act as a replacement drive for computers that still run on regular old hard drives. Used in this way, it will help significantly boost the computer's performance.

The M7V can fit in any space where a regular hard drive is used, however in a desktop, you'll want to opt for a drive bay bracket (not included) to keep it from moving around inside the case. The drive supports the latest SATA 6Gbps standard but will work with all SATA revisions.

Other high-end drives, such as the Samsung 850 Pro, tend to include a drive bay bracket, or cloning software or a USB-to-SATA cable to help you migrate to the SSD from a regular hard drive. The M7V includes none of those extras, but that's generally the case for budget SSDs.

In testing, the M7V did well for a value SSD. In fact in certain tests it was faster than some other budget drives, such as the Toshiba Q300 or the OCZ Triton 100.

The M7V also has a high endurance level, meaning you can write a lot of data to it before it becomes unreliable. (Read more about SSD endurance here.) Plextor says that the M7V can handle up to 80TB, 120TB and 320TB written for the 128GB, 256GB and 512GB capacities, respectively. More specifically, if you write about 50GB of data to the 128GB capacity drive every day, it'd take some five years before its endurance ran out. The larger capacities would respectively take double and quadruple that amount of time. In regular usage, most of us don't write more than a few gigabytes per day, and most days we don't write anything to the computer's internal drive at all.

In all, while the M7V isn't the fastest standard SSD on the market, it's also not the slowest -- but it is among the most affordable. It's a good SSD that will last years with normal use and give you a noticeable performance boost over any traditional hard drive.
