Ανεξάρτητα από το αν χρησιμοποιώ δεδομένα, ο όγκος δεδομένων μένει ίδιος.

Yes. Ανεξάρτητα από το αν is best learned as a set phrase meaning regardless of whether.

A useful breakdown is:

• ανεξάρτητα = independently / regardless
• από = from
• το αν = whether / if

But in practice, you usually do not translate each word separately. The whole chunk works like English regardless of whether.

The το helps turn the clause with αν into something noun-like, so that it can follow από.

So:

• αν by itself = if / whether
• το αν... = roughly whether...

This is very common in Greek. After certain prepositions or expressions, Greek often uses the neuter article το before a clause introducer.

So ανεξάρτητα από το αν χρησιμοποιώ δεδομένα literally works like:

• regardless of the whether I use data

That sounds odd in English, but it is normal Greek structure.

Here it means whether, not a real conditional if.

In English, if and whether can overlap, and Greek αν can also cover both ideas in different contexts. In this sentence, because it follows ανεξάρτητα από το αν, the meaning is clearly whether:

• regardless of whether I use data

So this is not saying if I use data, then...
It is saying whether I use data or not, ...

Because Greek usually does not need subject pronouns when the verb ending already shows the subject.

• χρησιμοποιώ = I use / I am using

The ending -ώ tells you it is first person singular, so εγώ is unnecessary unless you want emphasis or contrast.

For example:

• χρησιμοποιώ δεδομένα = I use data
• εγώ χρησιμοποιώ δεδομένα = I use data with emphasis on I

Greek does this much more often than English.

Because δεδομένα here is being used in a general sense: data in general, not a specific set of data already identified in the conversation.

So:

• χρησιμοποιώ δεδομένα = I use data / I am using data in general
• χρησιμοποιώ τα δεδομένα = I use the data / I am using the specific data

Greek often omits the article when the meaning is generic or non-specific, especially with abstract or broad categories.

Because they are in different grammatical cases.

• δεδομένα = accusative plural (here, the direct object of χρησιμοποιώ)
• δεδομένων = genitive plural (after όγκος, meaning volume of data)

So:

• χρησιμοποιώ δεδομένα = I use data
• ο όγκος δεδομένων = the volume of data

This is very common in Greek: one noun can appear in different cases depending on its role in the sentence.

Because Greek often uses the genitive to express relationships like of X.

So:

• όγκος δεδομένων = volume of data
• literally: volume of-data

This is similar to many other Greek noun combinations:

• ποτήρι νερού = glass of water
• ομάδα μαθητών = group of students
• τιμή προϊόντος = price of a product

So δεδομένων is genitive because it depends on όγκος.

Because όγκος is a masculine singular noun.

That means the words agreeing with it must also be masculine singular:

• ο όγκος = the volume
• ίδιος = same

Greek adjectives agree with the noun they describe in:

• gender
• number
• case

So here:

• όγκος = masculine singular nominative
• ίδιος must also be masculine singular nominative

That is why ίδιος is correct, not ίδιο.

μένει ίδιος means stays the same or remains the same.

Here μένει comes from μένω, which often means:

• stay
• remain

So:

• ο όγκος δεδομένων μένει ίδιος = the data volume stays the same

Greek could also use other verbs in similar contexts, but μένει ίδιος is a very natural way to express that something does not change.

Compared with είναι ίδιος:

• είναι ίδιος = is the same
• μένει ίδιος = remains/stays the same

The version with μένει emphasizes lack of change.

The comma separates the introductory clause from the main clause.

Structure:

• Ανεξάρτητα από το αν χρησιμοποιώ δεδομένα, = introductory subordinate clause
• ο όγκος δεδομένων μένει ίδιος. = main clause

This is similar to English punctuation in sentences like:

• Whether I use data or not, the data volume stays the same.

The comma helps the sentence read more clearly.

Not completely. Greek word order is more flexible than English, because the case endings already show many grammatical relationships.

The given order is very natural:

• Ανεξάρτητα από το αν χρησιμοποιώ δεδομένα, ο όγκος δεδομένων μένει ίδιος.

But you could also move the main clause first:

• Ο όγκος δεδομένων μένει ίδιος, ανεξάρτητα από το αν χρησιμοποιώ δεδομένα.

Both are grammatical. The original version puts the regardless of whether... idea first, which gives it more emphasis as the frame for the whole sentence.

Yes, grammatically it is plural.

• δεδομένο = datum / piece of data
• δεδομένα = data

In real usage, though, Greek often uses δεδομένα the way English speakers use data as a general concept. So even if it is grammatically plural, it can feel like a collective idea.

That is why a phrase like όγκος δεδομένων sounds very natural: it means the total amount or volume of data, not separate individual items.
