Performance vs. Transfer Size

ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. The 480GB model is again a bit slower than the 240GB one and write performance especially is noticeably lower. For example at IO size of 4KB, the 240GB model is about 150MB/s faster, which is significant. Even at higher IO sizes the 480GB Atlas isn't able to make up the difference.

    "I'd love to drop in a 120/250GB SSD and use it for the OS drive" -> Does your BIOS/UEFI even support that? I've often read that SSDs that are designed as caches in laptops are on artificially limited connectors.

    The only scenario for me to buy an mSATA SSD is to upgrade my Samsung XE700T1C which has a 128GB Samsung mSATA (830 variety I think). Upgrading to 240GB would be too small a step to justify the effort, so I'd just go with 480GB. And there, the M500 from Crucial retails for 250€ whereas the Atlas goes for 370€. Once Samsung enters the fray for good, I think they can undercut both. So I pass the Atlas offering. The 240GB offering is more price competitive, but it is still 15€ more expansive than the M500.
    As for "you don't really need any peripherals with an mSATA drive.", I'd like to get a small mSATA->USB case with the drive or at least the option for a kit that is 10€ more expansive.

    Outside of mobile use, the one application that msata excels at would be for a very small HTPC. Take intels latest NUC, attach a 240 Gb msata and (if you need) an internal blu ray drive, preferably in a fanless case, and you have a great HTPC system
