Consumer Grade SSDs vs Enterprise Grade SSDs
-
This is really trivial to figure out man, just look up the write endurance & do the math

@StrongBad my bosses.
He feels more comfortable with enterprise grade SSD's, I'm trying trying to determine if it's actually "worth it".
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.

It's all about the emotional reaction of "is it worth it."

One drive is Samsung 850 EVO 1 TB 2.5-Inch SATA III Internal SSD (MZ-75E1T0B/AM) the other is Hewlett-Packard F3C96AT internal SSD

I can't find anything anywhere with data on the F3C96AT. It appears to be an old product that has been off of the market for a while, from what I can tell.

Assuming you don't migrate to a larger array before you run out of space.
The OP has 6 TB of data today, but is starting with 11+ TB of total usable storage. We know his current growth rate is 13 GB for easy numbers. So that's 384 days worth of writes - wow in writing that out, that's less than 2 years worth of adds before he's out of space. hmmmm

That's growth, writes may be no larger than that or thousands of times larger. All depends.
-
300,000 / 13 = 23,076 days or 63 years.
-
That's assuming that we are writing to only a single drive. If we have four drives in RAID 10, that gets cut in half. So 126 years of writes.
