I missed the part about the SSD. Thought you were just going to get a smaller SSD to boot from and then a 1 TB standard for your data. Seagate and I are not friends but I have no data on the reliability of their SSD. I have read that their hybrid is not any faster than a regular drive and since I don't trust their regular drives I would avoid it.
I have a Silicon Power Slim S55 2.5" 480GB SATA III TLC Internal Solid State Drive (SSD) mounted in a
WD WDSL00S IcePack 2.5" to 3.5" SATA Hard Drive Mounting Kit Frame w/Heatsink
with a 1 TB WD drive for data (I think it was about $70).
I originally had a smaller 256GB SSD from SanDisk ($79 from Newegg) but it failed and I replaced it with the Silicon Power SSD which was on sale at Newegg for $109. (SanDisk did replace the failed unit but it took them a long time and I had to jump through a lot of hoops so they lost me as a customer) The IcePack Mounting Kit was $19 from Amazon. It lets you mount the SSD like it was a standard 3.5" desktop HD and also provides additional cooling (there are some plastic covered thermal/glue pads on it - you have to pull off the plastic before installing the SSD) . Makes a lot neater installation and hopefully the extra cooling will make it last longer.
It's a pretty neat setup. Boots up in almost no time compared to a standard HD.
