SSD: MLC vs SLC?

post #1 of 8
Thread Starter 
Not too familiar with the technology behind SSDs, but it is my understanding that SLC (single level cell) is faster and better than MLC (multi-level cell) technology.

(1) is this true? and (2) is it because SLC is a lot more expensive and if so (3) is there anything besides price that makes MLC better?

MLC uses a single cell and logically splits it into two.

So SLC is faster and longer lasting but more expensive. MLC is cheaper. That's it.

SLC is supposed to have a much longer lifespan than MLC, but the expected lifespan of MLC is still >10 years so it's not really worth it at the moment. SLC is also a bit faster, but like I said, the speed doesn't justify the price. Get MLC now, and if you really want SLC wait for a price drop.

How long they last in MLC form highly depends on the manufacturers. I have seen MLC drives fail within 6 months! You may go through all that trouble with MLC while SLC drives will last ages. If reliability is a concern, definitely go SLC.

The MLC SandForce drives are the way to go at the moment. There are SLC Sandforce ones (Vertex EX) but they have limited availability and cost you your house. It's not a good investment with SF2000 and G3 coming out soon.
