DS425+, RAID and similar production date hard drives
Hello
I recently purchased a Synology DS425+ NAS.
I have two questions about it.
- I’ve heard that you can also create the RAID via Synology. And that you can expand the RAID level while the system is running, so you don’t have to install all the hard drives right away.
For example: Start with just 2 hard drives in RAID 1. When the drives are full, connect a 3rd hard drive and switch to RAID 5. Later, if more storage space is needed, you could then expand to 4 hard drives. At that point, you could stay with RAID 5 or switch to RAID 6. Is that correct?
The advantage would be that you only have to install as many hard drives as you’re actually using for storage. And that would also save on electricity.
- As far as I know, you should try not to install hard drives with the same production dates. For example, you should order from different stores to get as varied production dates as possible.
That’s what I did. Unfortunately, I realized that Amazon and eBay all shipped hard drives from the same other seller. So now I only have 4 hard drives, 3 of which are from the same seller. As for the date, all the hard drives are from May 2025.
Do you think this is a problem? Or does it not matter that much, since even if I ordered from different stores, the hard drives would still have similar production dates?
If I’m going to use the drives one by one anyway (see Question 1), then it shouldn’t be a problem, right? What do you think is better? Should I have the hard drives in stock now for future use, or should I get them later when needed, which might result in drives with different production dates?
I’d love to hear your opinions and experiences.
Best regards, Marc
