Am looking to upgrade my system soon and was looking into SSD's, which ones the best right now for the money, slc or mlc. I was looking at http://www.newegg.com/Product/Product.aspx?Item=N82E16820231256, though i know it's mlc, but the seq write seems atrociously high. Whats the main diff between SLC and MLC btw besides longevity of speed?

I have a tough time believing that write speed, but it seems like a pretty good deal. The Write speed has to be before the 1275 firmware update.

SLC was initially faster than MLC memory. But that gap is slowing with the new controllers for MLC.

SLC is typically very expensive.

You can never tell what benchmark program they cherry picked their numbers from. Even more nebulous is OCZ has their 120GB Vertex at 180MB/s sequential, and 100MB/s "sustained."

CrystalDiskMark has the Vertex 120GB pegged at 145MB/s from 50MB to 1000MB file sizes for reference.

SLC has less latency, more IOPS, due to having only half the possible data states (0 or 1 vs 00, 01, 10, 11). The Indilinix SLC numbers are beastly, only falling behind in random writes vs the Intel X25-E. The SLC variants of both the Intel and Indilinix controllers have significantly faster random read/write performance than the MLC counterparts.

My guess on the sustained number is that it's the performance of the drive after it's been used for a while without the benefit of the TRIM comand or some other refreshing method.

The falcon uses the EXACT same controller as the Vertex.

Expect similar results.

The best $/GB now I think is the 256GB for $620+ ship at egg for the supertalent 256G ultradrive ME.

That was like 3 firmware versions ago... Any updates?

Yea, it's a real drag on the Vertex. Intel sure did their firmware flashing setup right. But at least they can be flashed. My OCZ Solids are forever locked at whatever firmware they shipped with.
