Actually, a minor correction for the article. The NVELO cache software for Crucial is actually a "Write-Back cache, and accelerates both Reads and Writes, the Write-Around cache described on the NVELO website is for Ultrabooks, where they use much smaller capacity drives (16-32GB) that don't provide a decent benefit for Writes. So, the Write-Back cache with the Crucial devices is more than twice as fast as the write-around cache for Ultrabook. And, both of these options are much faster than the latest Hybrid-HDD's, and much more efficient than boot drives...
That's unclear. I couldn't find any specific information on which strategy Corsair was using, and the CrystalDiskMark results posted on their own blog are rather odd:
Sequential and 512K writes take a nasty hit. I didn't go to the trouble of posting the VelociRaptor's performance figures here, but it's worth noting that the Accelerator+Caviar Green is only about 1/3 as fast as the 600GB WD's write performance in those two tests.
I'm not claiming that this makes the Accelerator Cache concept a bad one; it's entirely possible that CDM doesn't understand the caching structure properly. Check reviews of the already-released OCZ Synapse, however, and you'll see that there are certain kinds of write situations that a drive cache can't do much to accelerate. As I already noted, writes are a small part of the average user's desktop work, so that's really *not* much of an issue. It's just something to be aware of.
Yeah, something is wrong with the data on the Corsair site...
The following info makes sense
PCMark (overall) improves by 300% (The HDD suite would be closer to 10x)
Boot time improves by 500%
Crystal Disk Mark: 4K Random Writes go from 1MB/s HDD to 47MB/s
On Atto, all size Read/Writes improve by ~300%
Application load improves by 300%
But something is wrong with the Crystal Disk numbers... not consistent with other data.
Need to look into this.
Thanks for the follow-up, hopefully we'll figure this out.
