I’m making an inventory system and I want it to be how islands and bcw has theirs. They have infinite Inventory and I’m wondering if it’s a problem if I were to store hundreds of values. (if they were to have all items in their inventory)
I guess its 4mb per key the max limit, no matter the “elements/entries” is about size

I’m 90% sure the data store has a 50 character limit, not sure if that equals up to the 4mb limit.
On a side note, make sure to keep within the data store’s request budget so further requests don’t throttle.
I think your confused with another limit? Which is the key character or datastore name limit, not the overall data that can be saved (4mb).
Here is the roblox documentation about limits with datastores for more detail about these limits
Here are the highlights of the limits from the documentation above:
These are the character limits for datastores:
| Component | Maximum Number of Characters |
|---|---|
| Data Store Name | 50 |
| Key Name | 50 |
| Scope | 50 |
| Data (Key Value) | 4,194,304 per key |
How often you can read and write data in datastores:
| Request Type | Limit |
|---|---|
| Read | 25 MB per minute |
| Write | 4 MB per minute |
This is how often you can call each method per minute:
| Request Type | Functions | Requests per Minute |
|---|---|---|
| Get | GetAsync() | 60 + numPlayers × 10 |
| Set (limit is shared among all listed functions) | SetAsync() | |
| IncrementAsync() | ||
| UpdateAsync() | ||
| RemoveAsync() | 60 + numPlayers × 10 |

Each key can store up to somewhere around 4.1 million characters - as in, 4.1 million characters in a string (since datastores automatically type-coerces your data into strings).
That’s a lot of data you can store in a single key, actually - and if you compress that data (which you should, because of throughput limits) you can save even more.
Frankly, this is a bit of a non-concern. If you believe that 4.1m characters isn’t enough for you, consider sharding your datastores.
