As David mentions, most laptops currently use the 2.5'' SATA, which utilizes the regular size SATA connectors (power and data ... and are 5V/3.3V compatible).I'm kind of wondering about SSD's and laptops. Is there a different set of connectors for laptop SATA drives vs. the standard SATA drives?
If so, who makes laptop SSD's, and, has anyone used them?
I can't just plug a Vertex Turbo into a Lenova?
However, a growing number of laptops (and I'd imagine nettops) are adopting the 1.8" device size. For instance, the primary drive for Lenovo ThinkPads now use 1.8". This form factor for SATA requires the microSATA power and data connectors. It is also exclusively 3.3V. So if you were planning on using such size drive in a desktop machine as well, then you will have to take those things into consideration (All this is essentially recapped earlier in the thread here)
My understanding was that Toshiba was a large supplier for the 1.8" drives (I know this is what Lenovo was offering previously). The 2nd gen intel drives are now widely available too in this size (<-- note to Gilbo, as he asked about it a while back, though I'd imagine that he is plenty aware of this fact now).
As for plopping in a 2.5" drive in your Lenovo -- you can, but you'd have to use the ultrabay (and approp. adapter) for your device (suggest you carefully research the necessary requirements per model, as they may differ and be uncompatible btw them), and, if you are going to use it as the primary drive, then you'd have to switch the boot order in BIOS. For example.
