i really dont understand what all this sequential read and write things mean. but it confuses me cuz normal SSD the write speed is somewhere around 500 and msata is 175. but the price is the same. now just by looking at the umber you feel oh.. the msata is lamer.. and maybe it is.. but in the real world does that number difference make much difference say for things like boot up time, or copying files? how much difference would there be between the two if copying a 1gb file or say files equalling 1gb from one location to the other and also booting up the PC? and would both of them still be substantially better than an HDD? or is upgrading to an msata to keep the HDD inside the laptop not worth the price as it would be to upgrade to normal 2.5 SSD?
the reason why mSATA & SSD price is almost the same bcos of the usability of mSATA... there's no need to replace the current HDD when installing mSATA compared to SSD... besides, mSATA can be used as a cache drive, means no need to reinstall/migrate OS into the mSATA...
there's should be noticable speed difference between mSATA & SSD, but if you look clearly, there's different type of sequential read/write. the normal one that you mention (500 vs 175) is usually applies for large file.. instead, there's another sequential (4K) that is used for smaller files, which usually applies for os stuff that actually affect the normal daily usage...
and yes, both mSATA & SSD are better than hdd in term of speed, temp etc.. except price
as for whether the price is worth or not, it is usually depends on the user and the machine itself... for example, y480/580 can use both method, either mSATA/HDD + ODD combo or SSD + HDD combo but for y400/500 they better go for mSATA/HDD bcos the standard caddy isn't appliable to both laptop. so, if they wanna use SSD, they have to remove the HDD & probably change them into external drive. besides, i dun think that y500 user wanna sacrifice their SLI configuration just for SSD/HDD combo
