With PCM8's long test and our notebook battery life test both in our full review, our current SSD testing takes around two and a half days per drive. Normally that isn't much of an issue but when we have ten new drives in for review the time adds up. Between Jon and our Facebook fans, the pressure is on to post some early numbers on the new SanDisk Extreme Pro and Crucial MX100.
These two drives are world's apart. The Extreme Pro is SanDisk's new flagship SSD with a groundbreaking 10-year warranty and the best SATA III performance we've measured to date. The MX100 is Crucial's new economical / mainstream replacement for the M500 that breaks new ground in consumer SSD pricing (256GB for $109 and 512GB for $219).
Let's take a look at some early numbers.
PCMark 8 2.0 Advanced Tests - 1TB Class
Crucial didn't release a 1TB MX100 model although the M500 did ship in the extra large capacity. Here were looking at the SanDisk Extreme Pro on its own. On its own is exactly where the Extreme Pro is too, the drive dominates the 1TB capacity class size. SanDisk used the same Marvell controller found in the Extreme II but increased the clock frequency and doubled the die count. The Extreme Pro still uses 64Gbit die and is the only 1TB model currently on the market using that die size. As you can see the internals work out well for this model as it delivers amazing performance.
PCMark 8 2.0 Advanced Tests - 512GB Class
Both the MX100 and Extreme Pro overlap in the 512GB capacity class size. We're not trying to compare these two drives against each other as the price difference and the target markets are on opposite sides of the scale. We did want to publish some early numbers though.
The Crucial MX100 with new 16nm flash using 128Gbit die costs less than the M550 performance model but in some situations performs a bit faster.
The SanDisk Extreme Pro replaces the Extreme II and even though we didn't think it would be possible, raises the bar for both performance throughput and latency.
Look for full reviews in all capacity sizes in the coming days. At this point we're hitting a bottleneck with our notebook battery life test but as soon as we have all of the numbers together, we'll get everything published.
