Slow write performance means increased disk busy times so less idle or sleep time for the drive. The increase in busy time means more power consumption from the battery. The SP920 128GB didn't do all that well in our notebook battery life test.
It's a tale of two different drives with the same model number. Just hours before completing this review, I was asked why we were not putting all four capacity sizes in the same review and kicking the results out. Even though the 1TB drive and the 128GB drive share the same SP920 name, the performance in comparison to other products on the market is quite different.
At this time, we're not sure if Micron plans to sell 64Gb 20nm flash to third-party manufacturers like ADATA or if Micron plans to keep it for itself. ADATA has a number of very smart engineers, product managers, and accompanying staff, so they know using 64Gb is the best way to squeeze performance out of lower capacity SSDs. If ADATA didn't use 64GB dies, then either Micron isn't selling it to third parties or the price is prohibitive for ADATA to use it at this time.
ADATA did put together a nice accessory package for the SP920, but it's hardly a package that is completely unique to the market. The ADATA package is a lot better than the Crucial offering with the M550, but Crucial has the performance in this duel. You can't keep the OCZ Vertex 460 120GB off of the table, either, even though the price is higher. The Samsung 840 Pro costs a bit more, but the EVO is in the same price range of the SP920 and M550. Both drives have latency issues in this capacity until you enable RAPID Mode.
Unless you need the accessories, I'd say pass on the ADATA SP920 128GB and look elsewhere for higher performance. If ADATA manages to significantly undercut other 128GB capacity class size drives, then things change, but at the time of writing, the same money delivers more performance from other products.
