I've done a lot of research on SSDs before I bought Samsung ones, first 830 128GB for OS drive and now 256GB for games and virtual machines. Samsung are the only ones apart from Intel (more expensive), where all the components are made by one manufacturer, memory chips, controller, interface all made by Samsung. If something is designed from scratch as one complete device, it's usually much more robust and reliable. We have all heard stories about SSDs running on sandforce controllers, and constantly failing on all fronts, something that is less likely to happen on 830s.
Windows 7 benchmark gives me 7.9, which is maximum score that can be received for a storage device. I've had no problems whatsoever installing it with attached SATAIII cables on my 6Gb interfaces. The associated software (not required to run) called Samsung SSD magician, does its job well at disabling built-in services that may shorten the life of any SSD, and are no longer necessary (defragmenter, indexing service, etc). The disk's temperature reported by Magician is below 35 degrees, which is probably artificially raised above my room temp (23) by three high performance HDD WD drives sitting in the same case, running roughly at about 65-70 deg.
On my i7 2600k 3.4GHz box with 16GB RAM box, Windows 7 x64 Home premium, starts in less than 5 seconds, not counting the POST sequence, and is desktop ready in just below 15 s (that included starting the antivirus, firewall, device tools, some background apps, etc). I should mention that it's a 2 years old Windows installation with > 600GB of software (including games) installed, so not a fresh Windows install.
All in all, very good purchase, and acceptable delivery.
