back to article Samsung hops onto MLC roundabout

Samsung is sampling its first enterprise multi-level cell (MLC) flash, with a pretty high performance solid state drive, and hopping onto a roundabout already crowded with other suppliers such as Anobit, OCZ, Pliant and STEC. The product comes in a 2.5-inch form factor, in 100, 200 and 400GB capacity points, and with a 3Gbit/s …

Still not keen on the idea of using MLC flash for enterprise-grade storage...

Even the best 2-bit MLC flash has a relatively short lifespan compared to most single-level cell devices (note that this assertion does not take into account wear-levelling and the use of TRIM commands to extend life).

STT-MRAM (Spin Torque Transfer Magnetoresistive Random Access Memory) shows quite a bit of promise

but is some years away from production, and with fab construction (or conversion) costing billions of dollars, you can bet that flash manufacturers are going to milk the technology for everything they can get before they're forced to switch to a different technology by nano-scale quantum effects.
