The Good The Plextor M6S has low power consumption and is a great performance upgrade for a computer that still runs on a regular hard drive.
The Bad Compared with other solid-state drives on the market, the M6S' performance is disappointing. It also comes with only a short three-year warranty.
The Bottom Line With unimpressive performance that doesn't match its high price, there's no reason why you should pick the Plextor M6S over other SSDs on the market.
Slow performance for the price
When compared with any consumer-grade hard drive, the Plextor M6S solid-state drive (SSD) is energy-efficient, not to mention much faster. When you stack it up against other SSDs, however, its slower performance just doesn't measure up.
Available in three capacities -- 128GB, 258GB, and 512GB, with the suggested retail prices of $140, $250, and $500, respectively -- the new M6S is the first I've seen from Plextor that costs less than $1 per gigabyte at launch. That's a welcome change from the company, but they're still much more expensive than competing devices.
If the Plextor sold the M6S's three versions at around $70, $150, and $300, then I'd recommend them. But at their current prices, they don't deliver performance you should expect. That makes them far from the best choices on the market. Until their price goes down significantly, choose something from this list, instead.
