In reply to Les@TheSSDReview. I guess the price difference is SLC vs eMLC, (correct me if I'm wrong) and their additional work on putting it together really well in terms of the heat dissipation. But in real terms I guess this comes down to longevity? It would be very interesting if you could do some applied but theoretical analysis of longevity comparisons. For example, if serving a database or web server with x writes and y reads per day how long would each last? I think the SLC is in the millions so that can be counted on for 5 yrs+ but the question is, with the features of the enterprise SF chip, what life can be expected there? The speed should be comparable, maybe with a slight bump for this drive in IOPS.

In reply to lightminer. Awaiting arrival of the OWC SSD.

Thanks for the detailed report. Can you compare/contrast this with the OWC enterprise drive, which is 1700 vs 6000 for the Toshiba. Is it worth 3 times the price? I do see the attention they paid to heat and don’t know if OWC has done the same homework, but the OWC drive does use an enterprise SandForce chip which should have the same features as the Marvell.
