EconolineCrush writes: SandForce's SF-1200 is one of the most intriguing new flash controllers to hit the SSD market. Due to aggressive overprovisioning, the first wave of consumer-grade drives only squeezed 100GB of user capacity from 128GB of flash. SandForce has since dialed back the overprovisioning a little in its firmware, fueling a new batch of SSDs with more competitive 120GB capacities. As this review of Corsair's 120GB Force F120 illustrates, the increase in capacity has consequences for both longevity and performance. Desktop users looking for an SSD to house their OS and applications probably won't be fazed, but those contemplating the SF-1200 as a low-cost alternative to enterprise-class SSDs are probably better off with higher overprovisioning.
