...A thought and it all depends on HOW much data you accumulate and need and even use.
one 1tb drive < shett can it. It is on the road to failure is my guess and I would not have it in my system being so IFFY.
1 250gb drive < Probably okay to keep for data storage.
1 300gb drive < Probably okay to keep for data storage.
Okay you have already ordered the 2TB thingie? Right?
Had you not done so and the two drives above would have sufficed for you data storage, I would have certainly made the suggestion to get an SSD. I have just bought 4 new SSDs and none of them were the higher dollar 850 Samsungs. Don't need to be for me. Almost any brand of 3rd or 4th generation SSD will hold up and at the same time make your computering so much quicker to your eye and fingers. You cannot in your mind picture how much faster apps open and stuff just appears on the screen when the O/S is on SSD. We cannot splain that in words to show the real 'new' speed.
You can spend $500.00 on overclocking parts and pieces and not give the same overall effect as just about any late 256GB/$105.00 SSD for you O/S. Once on SSD for O/S you will never go or make that never want to go back to a platter drive for the O/S. Never.
I have two very early Kingston 120GB SSD's in Raid 0 since I "know" they are slower than the newer SSD drives and the Raid 0 effect is to bring those two slower drives into 2015. But my four newer 256GB drives are of two brands and they too will go in Raid 0 as S_B spoke about. I am just a glutton for punishment running Raid 0 on an AMD chipset mobo, but heck it is fun and I image the Raid 0 at least once per week for safety. Hehehe.
Okay ole faht thru with his rambling.
