I ebayed that for a frankly ridiculous £150.

Fair. I’d have done the same

That a good idea. I did offer to my nephew but he's all about his switch.
I was also thinking about selling the 970 on the computer, but then that would render the rest of the system unsellable... Will need to ponder the options

It only took 36 hours to backup 14TB... so what's that, 100Mbps or thereabouts? This was via USB-C from a Synology to the external drive. I tested the external drive for write speed first and could do about 220Mbps sustained for 500GB... so I guess the bottleneck during the backup has to be something internal to the NAS or perhaps the RAID controller (it's RAID6).

Still... it's acceptable as a full backup time. In future it'll rsync the difference. And something like 1.5 days to fully restore is not a nightmare (Cloud backup would be weeks).

I flogged my 970 (for the above ridiculous £150) as it is so much easier to sell and ship just a card compared to a computer.

Finally got the 2x Supermicro NVME Gen4 re-timer cards working.

Driving 8x 2TB Samsung Gen4 NVME in RAID0 using RAIDIX Era.

Getting ~40 GBytes/second sequential read speed, still tweaking to be done.

Out of interest why have you got the CPU Cooler at 90° to the airflow?

It’s an AMD EPYC motherboard, cooler designed for Threadripper which has a 90-deg socket orientation.

I tried a dedicated EPYC 4U cooler with correct orientation, but it performed worse than this Noctua.

Makes sense!

Does it run Crysis tho?

Does anything?

Just noitced the blood on the left hand fan

Lol yeah, lacerated myself on the razor sharp swarf after butchering the chassis in order to re-mount one of the 120mm fans as the cable sprawl from the bifurcation riser to the NVME drives was too much to handle with the fans in their original position.

Can’t get hold of suitable Gen4 NVME hot-swap caddies in the UK. Best I could do was mount the drives individually and deal with the rats’ nest of data and power cables.

This is all for a real-time video recording and hot-storage editing array.

have been doing a fair amount of vector drawing the last year and now i have my beefy new pc I've been doing some blender 3d tutorials so I can learn 3d modelling to make rendered art and also design stuff to print on my 3d printer but drawing with the mouse is a pain as i'm a lefty when i use a pen but i use a mouse with my right. stumbled into some cash this week thanks to an unexpected late-christmas bonus so I've picked up a 24" xp-pen display tablet which arrives sometime today.

rearranged my desk last night to make room for it so should be ready to plug in out of the box and go.

annoyingly while researching before the money came in I found it with a double discount on amazon that would have saved me an extra £100 as they'd knocked nearly £200 off the usual price and also had a voucher for £100 to apply but it expired about an hour after I saw it. I emailed their customer support to beg to get the voucher as well when buying but I had managed to stumble onto it at the overlap of the two promotions and it wasn't intended to be sold that cheap.

other option was buy for £190 less than I just paid on their store on aliexpress and have it shipped from france in about 3 weeks but for a few obvious reasons I didn't think that would end up being the money saving deal it appeared to be by the time I had it in hand.

still I'm am very excited. feels like christmas all over again.

Anyone use a Synology NAS and know if it's possible to find out which process(es) are accessing the HDD?

Mine's thrashing constantly and I can't figure out why. DS216+II if that's of any relevance.

It's the search indexer or the music service.

I use a Synology NAS and had this problem a very long time ago. I slowly disabled everything until eventually I got it to the point that the only thing running was the file manager and file network shares.

There is a load of things installed by default which you don't need... disable and delete things.

Also... https://synocommunity.com/package/synocli-monitor will do what you want. Install and enable SSH and then use standard Linux tools to see what is happening.

Had a feeling you used one, thanks.

Mine's currently a single 8TB drive but I've just liberated a 1TB SSD from the PS4 so thought I'd look into installing the OS on that. Assuming it doesn't make any difference to the disk access issues I'll give your suggestions a shot.

Don't suppose anyone has an old Acer Aspire charger going spare?

The power brick part of my OH's personal laptop has gone.

TBH we should probably look at getting a new one, but it sees such little use nowadays it's easy to keep postponing. I'm sure we were meant to look in last years Jan sales.

would need to pair it with one for that model as they wont all be the same.

have you tried ebay? quick look suggests aspire chargers are about £10-15 posted.

Do you still have the power adaptor?

If so, check the polarity diagram and voltage and then jump onto Amazon and order a cheap one.

You're probably going to want to match the Amps too

I bought a spare for my Aspire laptop from eBay, probably only £15 or so.

I have one stuck to the underside of my desk where my laptop sits most of the time. The other is used whenever I take the laptop on the move.

Same for my work laptop although the spare power brick came with the dock I ordered.

They do vary by model though, my Aspire is about 18 months newer than my wife's Aspire and has a different connector.

[EDIT] Bought mine from eBay from "LPS-GoPower". Just needed the laptop model number and can search in their eBay shop. It was £16.99 which included P&P.

Cheers all. I should probably have posted up the exact spec.

My old netbook charger works, albeit slower, so we're not stranded. Just wondered if it was the sort of thing someone had lying around I'll have a look on eBay.

Anyone needing any more storage?

I have two HDD that aren't being used (and haven't been used much historically)
Seagate 2TB (ST2000DM001)
Western Digital 4TB Intellipower NAS

SATA cables included

£50 for the 4TB NAS one (£140 new currently)
£20 for the 2TB
Or £65 for both

Forgot to mention that SSD upgrade for Synology NAS was a great success.

UI is much snappier - as expected - and the HDD now has nothing on it other than contents of the Synology Drive backup. No more thrashing, just the occasional chatter which I've barely noticed. Wish I'd thought to do it ages ago.
