Since we use two test labs for evaluating client and enterprise features, the enterprise tests will follow next week by Paul Alcorn. SanDisk has high hopes for this dual purpose product and designed in features that we have yet to discuss. Unlike the Extreme II, X210 users get the full capacity of the drive. This way end users can set the amount of over provisioning they need. On the client side, 7% is a good starting point for heavy use, but when applying server loads, some will find that 28% is better, especially for high write environments.
SanDisk has essentially taken the quality of the Extreme II up a notch when it comes to data reliability and traded a small portion of performance. At the same time, the X210 gives access to the full span of the flash and added the advanced power saving features from DEVSLP.
The result is a drive better suited for business use than the enthusiast grade Extreme II. Windows 8.1 should hit on October 17 and we expect a lot of news about Haswell ultrabooks with DEVSLP capabilities at that stage. Until then, we won't try to guesstimate the increase in notebook battery life performance, but given the power numbers SanDisk is quoting, it should be a significant upgrade.
On the performance side, the X210 is the best OEM SSD I've tested to date. We've tried to run through every SSD that comes in a notebook from the big box guys - Lenovo, Dell, HP and so on - when we have the opportunity.
Part of SanDisk's vertical approach is to increase the number of products shipping with high performance SSDs. This will have an impact on aftermarket sales, but in the end, customers get great performance right out of the box, without going through the upgrade hassle.
