It's not too hard to find inexpensive solid-state drives that offer either a lot of storage or brisk performance, but finding both? That's hard. Intel, however, thinks it has a chance. It's launching a budget 2.5-inch drive, the SSD 545s, that theoretically offers both high capacity and speed without straining your wallet. The key is the nature of the storage itself. This is the first shipping drive to use extra-dense 64-layer 3D flash storage, which lets Intel offer an abundance of space using relatively few chips (and thus a lower price) while maintaining performance. The 512GB debut model, for example, costs $180 brand new -- it's not the cheapest out of the gate, but street prices could make it very tempting.
