SSD and XP Pro - worth it?

Background: I have a tower PC (AMD Quad Core), I bought a few days before release of Windows 7 in 2009. Since Vista had a very bad reputation, I stayed with Windows XP (Pro 32). The computer now has some more years on the clock is running, but to my complete satisfaction. Sometime 2 years ago the fans and the power supply were replaced by really good parts, also the internal hard drive complemented by a 1TB drive. As now increasing signs that the system disk slowly give up their mind, I decided to upgrade the system with SSD. So forth with 2 Samsung 850 Evo with 512 GB. As it worked out, and what were the problems?
1) Connecting the SSD is a breeze, as a precaution I had two mounting frames together with the instrument.
2) With the software from Samsung is the system drive has been cloned to the SSD (320GB to 512GB with no problems).
3) disconnecting the hard drive and booting from the SSD - worked immediately.
4) Installation of Samsung Magician software and system performance to maximum service life set.
Incorporated 5) and the second SSD (important) formatted! So that the system also recognizes this.

And now some of the endless discussions and more or less good advice to migrate to HD SSD and performance in internet forums:
a) "Better the same Windows 7 or 8!" - I wanted to stay conscious with my XP and it will also, to the computer one day abraucht. I had simply no desire to set up completely new computer, especially since I no activation for MS Office have become more free. And the thing on and on yes.
b) "AHCI mode in the BIOS" - tried system does not boot, so back to IDE while bleibts.
c) "Alignment" - was with me "BAD". In Internet circulating how to correct the above freeware programs instructions, - that was too dangerous. So I for 20, - Euro bought a tool of Paragon and corrects both disks so. May sound diletantisch, but has saved me a lot of trouble and no data destroyed. And both SSD run after really fast.

In summary therefore: Although XP, the system also is actually suboptimal for the SSD and ancient, this boot is now a matter of seconds (say less than one minute). Programs start - felt - incredibly fast and the rattle of the disk and I do not miss. The move has so definitely worth it, and if the computer now holds a few more years, I'm happy and satisfied. And I hope my review helps a little when still undecided.
