Initialization time for TS-453D

Post by f15radar »

Hello,

I am thinking about buying a TS-453D. I will put 4 WD 8TB 7200 NAS drives in it. How long will it take to perform the initialzation and create the pool? I will have all 3 types of systems cheked (Win, Mac, and Linux).

Additionally I also have the following questions:

1) Can I add more drive bays later?
2) Can I use different size drives such as 4TB,4TB, 8TB, and 8TB?

Thanks.

Initialization will take a while..it runs with <100MB/s (probably)

1) Yes.. cold..but why?
2) No, if you mix them upon creation, the smallest drive dictates each drives size, when you try to add smaller drives later, they will not be added at all

So at 24TB and 100MB/s, it would take over 70 hours for initialization? It seems quite long since my 10 year old RN104 takes a little over 100 hours. I would have thought they would be much faster today. Is there anyone that has actual experience and can give me what it took them to initialize? Thanks.

I setup a TS-853BU up a couple of years ago with 8x6TB in RAID6 took the best of two days to sync the raid fully

you could but it's not ideal.

it will treat the 8tb as if they were 4tb.

so it's not gonna be 4+4+8+8

instead it will be 4+4+4+4

use the raid calculator to then figure out your total usable space
https://www.qnap.com/en/selector/raid-selector


but the gist of it is, you paid more for 8th, but you are not benefiting from that extra space because when you mix match different capacities in raid 5/6 it will cap it to the lower capacity among the drives when you do so.

this is why normally you would plan ahead and decide you will be using X tb drives. all drives being the same capacity.

Sorry to bump this guys but new-be question as I am in the same situation as above with 2x4TB + 2x8TB - I understand that pooling them would take the size of the smaller drive (4TB) although what happens if you create 2x RAID(1)? One with 2x4 and the other with 2x8 ? Would it make sense to do so and in the future replace the 2 drives with new 8TB drives and add them to the RAID?

pooling two RAID1 would make

4TB + 8TB =12TB
replacing later with two 8TB would make
8TB+8TB =16TB

starting with a RAID5 (effective 4TB accross)
4TB*3=12TB
replacing the two 4TB with 8TB later would be
8TB*3=24TB

RAID5 would yield better future space usage

Gotcha. makes sense. And there is no problem replacing the 2x 4TB down the road if it’s RAID(5), right?

you need to replace them one by one (rebuild inbetween)..no problem otherwise

but don't forget the backups (a raid is not a backup)
