I think Synology have no problem transferring large file in high speed.

You can check the write/read speed they state in the website.

I m using DS1815+ and run on aggregate Lan with switch. The speed is damn fast.

I do post way back the setup and speed test in this topic.

It will separated into 2 volume if different size. As what I experience now.

Are you still intend to keep the 3tb ?

Better migrate the data to 4tb, takeout the 3tb. Replace with 4tb.

No problem at all.

I m not familiar with the IP cam for NAS.

You can check on their Forum and the NAS manual setup.

Copy the setting over to the new NAS. Quickconnect will be in new NAS.

Than transfer the content.

What you want to use it for ?

5x4TB might not be enough. Depend your std quality you want to keep.

Very hard to upgrade when the cost is high.

My 4x6tb and 1x3tb already full. Upgrade to 10tb or 12tb... That hdd cost killing.

6tb so expensive now ?

Remember brought that time with NAS about RM560/pcs.

Damn, like that more difficult to upgrade the HDD size. The cost is killing.

Will check the HDD 12tb cost with my supplier.

I m using WD red. So far so good. Don't no how reliable the SG ironwolf.

Been RMA for my portable WD HDD which brought in US. I email to them. Trough email responds I send it back to WD in Vietnam. Have to bear the shipping cost. In 2week time, they send a new 1 to me.

Brought 4yrs ago.

HDD should be getting cheaper per byte. No?

I don't have good experience with seagate HDD previously. I hope it improve now and would like to change to ironwolf. Cause it's cheaper.

For server, my experience so far is Samsung and WD. Mostly now all WD red.

So far the temperature is



In the store room.

Will wait till end of this yrs see Amazon sale got cheaper iromwolf or not. Would like to get 4pcs 12TB or higher.

Local damn expensive for NAS HDD.

It might be due to the shrinking of the HDD market, the price can't be cheaper anymore? SSD is getting cheaper.

But I read all said the same. Better to be have a same brand and type of HDD for NAS. If mix, will effect the speed. Not sure what else.

kena before my NAS bruteforce. Slow down the network like crazy.

Last last check, hack from China from the log list.

Last friday suddenly 1 HDD 3TB Wd develope bad sector and crashed.



This HDD don't have raid and data protector. But lucky I can copy out the file.

Immediately swipe the hdd out. This time I try not to switch off the NAS.

Slice out the bad hdd and slot in 4 hdd. It detect new hdd and beep warning.

Than perform setup and wait for it finish. Before copy back the file.



Overall, it is easy solving problem and much more safer for data on the new NAS now. Compare last time.

Why waiting?

I start 13yrs ago.

Synology DS1815+ with 24TB. In the mid of upgrading to 60TB for this yrs.

2 week ago, suddenly 3 drive start to develop bad sector on my NAS. Beeping whole day.

2 drive was able to repair even report of I/O error and showing bad sector. probably minimum damage. So it still showing "Normal".

Taken out the drive to check with PC. Showing plenty bad sector. No choice but to change.



Even it can be hot swap, but I don't take the chance. Off the NAS before swap out.

For RAID, it cannot replace all the bad drive together. It has to be swap 1 pcs at a time. After rebuilding the parity check, and show normal, then only able to swap another drive.

Otherwise, all your data are gone. It's a risky repair since no way to back up the large size file.



This time I try the seagate ironwolf. No more WD.

WD drive last me about 5yrs. Pretty short life compare another Samsung drive in the NAS.



Run back the NAS and repair the Volume. For such a big size drive, it took 24hr to repair. So about 3days to finish up the process.



I guess more drive will die in a short time. Since I buy it in batch. Got to standby extra drive.

Having a NAS and taken care is expensive.

Will do.

But it cost me alot to swap all out.

Will buy 1 by 1 slowly swap it out.

The price of ironwolf going up this 2 weeks.

In a long run for large data like me, it cost more for using cloud.

"Ransomware, fire, flood, theft, brick falling on your NAS" -- This all been taking care.

I have been using NAS for over 13yrs. Spoiled 2 NAS. So pretty understand the disaster might coming.

I can't stream media with cloud.

Data is not just me using. It's for whole family, relative around the world. They easily access with a smartphone.

Don't ask me to train those relative aunty/uncle using the cloud.

The most reliable is those drive that run at 5200rpm. As long as the NAS can stream media at home is fine.
