Consumer Grade SSDs vs Enterprise Grade SSDs
-
Great question - considering changes in technology, I'm curious to hear the answer too.
-
I'm reading this here to get an understanding.
-
Are you including the warranty and support in the "double" the cost numbers? Because that is where most of the money normally goes.
-
The base reaction is just the failure rate from consumer to enterprise.
No other considerations are included.
-
Depends on your workload. If you're running anything that's super crazy write intensive then it might be worth it. Most regular scenarios I'd bet that Samsung 840/850 Pro's will do just fine.

Whose base reaction?
-
@StrongBad my bosses.
He feels more comfortable with enterprise grade SSD's, I'm trying trying to determine if it's actually "worth it".
-
This is really trivial to figure out man, just look up the write endurance & do the math

If it is about "feels", does "worth it" come into play?

I don't consider this trivial.
If he has 6 TB of used storage today, and we assume that will be mostly static, and we add 12 GB a day - again as static files, I'm not really sure who to figure this out?
The one great thing Dustin has going for him.. he isn't running SQL or any other big DBs (yes he has AD which is a DB, but you get my point), so he won't be writing/deleting/writing/deleting, etc.

You are looking for hard numbers as to how long it will last. That's hard. Very hard. But that's not necessary. You can just do a comparison. Does the enterprise last 10% longer, 50% longer, 200% longer. You need for use rates, just use the relative rates and the price difference and apply.
-
So here is the question... on the drives being considered what are the prices and the write durability numbers?
-
@Dashrender round up to 20GB/day
Samsung specs 850pro @ 300TB written
300,000GB / 20GB = 15,000 days / 365 = 41 years
What about 100GB/day?
300,000GB / 100GB = 8 years

Sure, but if his environment is mostly static, doesn't this really change the way you look at it?
For example - If I want to build a cold storage system that will be write:once read:infinity, the durability of writes is much less significant.

Depends. Are you trying to determine the relative value or are you trying to see if they are worrying about silly things? We already know the latter, so it must be the former.

In which case we know the answer already.

Sure, if you are assuming you're writing to the same spot on the disk - the only time this matters. But if you are only adding 20 GB a day, and not changing the old stuff, that number goes MUCH higher.

If they are worrying about silly things, doesn't that make the former moot?

If you constantly add anything each day, you will start overwriting.
