SSD in RAID0 and lifespan

post #1 of 5
Thread Starter 
I have 2 Samsung 830's in RAID0 in my PC.

I was thinking about how RAID0 would effect the lifespan of the SSD's.

Let's say I write 1 GB of data every day in a single Samsung 830 SSD and let's say that with 1 GB/day the single SSD will die in exactly 1 year (pure random numbers).

Now let's say I write 1 GB of data every day in a RAID0 array of 2 Samsung 830's. If I am correct RAID0 achieves it's performance by writing half data in the one SSD and the other half to the other one. So if I write 1 GB/day each drive would have 512 MB/day of write, so in theory both of the SSD's would die in 2 years so it would double their lifespan.

Tell me what you think of this, I am probably wrong because i have limited knowledge on these things but I want to hear your opinions.

Calculations have shown that even with heavy read-write and sequential write applications, you can expect a lifespan of 5+ years from your SSD. In 5 years, chances are you will have purchased and moved your data to something bigger and better,

Using a RAID0 setup may increase lifespan, but only in the same way that storing files on external hard drives and flash drives would. Long story short, unless you are crunched for space, I wouldn't bother with running them in RAID.

As a side note, SSDs don't usually *die*, instead you will probably see some capacity shrinking as the drive starts to forget about bad sectors that cannot be written to.

yes it should double the lifespan.

only thing you would be missing with RAID-0 is trim. without trim, you have to erase the data in the cells before you write the data first, making it slower. trim does not increase the lifespan.

but like the above poster mentioned, RAID-0ing just to double the lifespan is not worth it. you can get 5-10 years out of the SSD easily.

As said above, you lose TRIM with RAID depending on your motherboards support/drivers from Intel.

That said, the Samsung 830 SSD's are -insanely- durable, and good at maintaining their performance nearly full time, even when written to every minute, 24/7/365. You probably won't notice too much speed degradation (due to lack of TRIM) unless you do write to it constantly. The 830's have (slow) but very effective garbage collection to keep them in decent running shape. I'd say go for it.

I actually already have gone for it a while ago and the double lifespan was not the reason. I went for it for other reasons in another thread I posted back then but anyway thank you for your feedback i was just curious if what I thought was right.
