Corsair Force Series GT Family Review Discussion

3 posts in this topic

As with most SSD reviewers, StorageReview is typically sent a 240GB capacity drive from a new family of SSDs for review. There are several reasons for this, but in the SandForce world, it's generally because the 240GB capacity is the fastest due to NAND die configuration. Once the 240GB review is complete, we try to come back and get the more mainstream 120GB capacity as well, due to its favorable price point. These reviews, while detailed and informative, don't analyze an entire families' scope of performance though. That's the purpose of this review, as we examine the entire line of Corsair's Force Series GT SSD family. We're breaking down the entire performance profile of all capacities the GT comes in to finally get a clear picture of not just the GT's performance profile, but the SandForce SF-2281 controller coupled with 25nm synchronous NAND as well.

For desktop workloads I think we're luckily close to "fast enough anyway". But otherwise.. it's impressive to finally see these massive differences in (real world) performance between the capacities. And going into the next die shrink we may start to see 16 GB dies and get even less channels on the low capacity SSDs.

I wonder since a long time if it wouldn't make sense to get more bits / bandwidth out of individual dies. Is it the external pin density? The dies can't get much smaller since the packaging cost per die would become too large. But what's limiting them to "just slap 2 current dies together onto one chip"? Give each of them it'S own bus and there's approximately 0 redesign necessary at the chip level.
