Single or double SSDs? - Page 3

post #21 of 30
One large drive for simplicity. If you like to mess with hardware because you can, then go multidrives. If you already owned a 120/128 SSD and caught another on sale, I could see it.
Going new, one drive rules.

Contrarian post here. I have a 120gb Samsung 840 as my system disk, a 250GB Samsung 840 Evo as my SSD game drive and three more HDDs for games, media and backup respectively. (each 1TB).

I prefer to keep my system drive clean and for the exclusive use of windows. I put my most demanding games on the 250GB SSD and leave the bulk of my steam library on a WD Caviar Black HDD.

I used to back up the steam library but there is really no point, just download it again if you need to.

Regarding SSDs and games. Newer games are making more and more use of high res textures, and often stream these textures in during a level. You won't see this as loading time as its streamed but with the SSD in place there will be less instances of texture flicker and pop-in as the streaming will work more seamlessly than with a hard drive that needs to spin up and seek.

I also like the fact that in single AHCI mode and not raid you can pull one ssd and pop it in another system without rebuilding the array or losing the info.

Raid is good, I had raid 0 Seagate 320gb 7200.10 and WD 640 aaks but honestly with SSD only thing I think really improves is benchmarks.

How about we take each day as a single data point and say I have booted more than 365 times without an error. Is that statistically confident enough smile.gif

Edit: Overall I am not pulling for Raid, because I would trade my 6 drives for a 1TB evo if someone offered me, but I will say I don't buy into the failure rate nonsense. I keep an image weekly on sunday nights, do that and it's no problem, if it is ever even needed.

No... because it's the same array. It would be like saying: All light bulbs last 3 years because my one light bulb has lasted 3 years. We can be sure because I use it every night.

It's not failure rate nonsense... it is basic statistics. Go grab some datacenter numbers with thousands of drives. Only a few companies like Google or Backblaze have publically released numbers and they have been cleaned.
Once again...

^ Indeed, failure of a drive is just a matter of chance and manufacturing that grows larger with time the longer a drive is in service. I'm just happy my Samsung F1 1TBs are kicking after 4.5 years now
Despite this I'm wary of my 3TB seagates that I just got in December...

My vote stills goes to a single SSD however thumb.gif

Another vote for single SSD's.

I raided them in the beginning for clients at their request, after seeing null benefit, I really just dont feel a need to raid them, a single larger drive is often cheaper as well, and seems to be just as fast.

I have gone with 2 SSDs 1 for the Os and another for Apps on the premise that as they are on different controllers they can be read from and written to at the same time.

If you have the extra money, I have been absolutely enthralled with the Intel DC S3700, having gotten a pair for my "superoverkill server", and even under the most intense sustained loads I can manage (8hrs of constantly variable R/W IO, as a buffer to 8x 15krpm 600GB SAS HDD via PCIe3.0/SAS12Gb Areca controller), the drives maintain insane consistency of around 0.2 percent! 840 Pro's were about +/- 73 percent!

I just got another for desktop use, and it is the future. The drive simply doesn't know how to stutter, and I am now of the opinion that max transfer rates are almost inconsequential compared to IO consistency.

Yup, Anandtech even modified their SSD review process due to this drive. Basically, peak performance does not matter that much anymore since all SSDs can hit high values. However, consistency is more important now since that's the constant use, real-world numbers.


If you over-provision the Samsung 840 Pro's, their consistency gets better though: http://www.anandtech.com/show/6433/intel-ssd-dc-s3700-200gb-review
