I bought an SSD a week or so back - my first; and the performance is nowhere near what I expected, so I'm wondering if it's something I've done wrong or if it really is that slow.

Samsung SSD 840, 250GB; it has 23.2GB set aside for over provisioning.
The Magician performance test gives 524MB/s seq. read & 257MB/s seq. write.

My problem - why is Windows boot still taking as long as it did when I had was using an HDD? I know this isn't a high-end SSD, but still.

Couple of things to check:

Did you configure it in BIOS under AHCI or IDE?

Did you make sure TRIM is enabled under windows?

Also, is it configured under SATA2 or 3? [Depends how old your motherboard is]

AHCI mode on in bios.
Install Windows with UEFI

Now it should be faster. It is much faster for me on my main computer and my HTPC.

AHCI on, connection SATA3.

Looked into it and it seems I need me a reinstall since I hadn't enabled EFI mode for setup. Meh, too much shit on it already, almost have to scroll down when uninstalling stuff.

Does UEFI make a difference when booted or is it just boot speed?

Not sure. Booting is the only thing I noticed a big difference in.

It's because of partition alignment, UEFI requires partitions to be aligned.

It should work on BIOS mode as well, as long as the disk is SATA, has no partitions, and you choose to install on the unallocated space. This way Windows creates the partitions and aligns them if appropiate.

google for BootTimer.exe, and then download it from a trusted source and go to properties then check "run this as admin.."

and compare boot time when changing settings, SSD on laptop have a great impact, i'd read a comparison between win7 & win8 to see that boot time went down from 27 to 18 (in test setup), that is still too much, cause last time i checked my laptop's bootup time it was under 10 seconds (9.9xx) without tweaking too much..

edit: ran it again and it took 8.8 seconds

Clean install in EFI mode helped a bit, but it might just be the clean install.
