The reason for FedEx packages being more damaged than USPS packages actually isn't FedEx's fault. They accept heavier packages than USPS, so that means if a shipper doesn't pack their package correctly, when that 150lb box of farm tools slams into your 6lb box of plastic in the sorting machine, your package gets crunched. Meanwhile USPS only goes up to 50(?) lbs, so your box just doesn't get slammed as hard. TL:DR your packages get damaged in FedEx because the shipper didn't pack them right.

I just completed a 24 X 18T build that's almost 1/2 PB. I bought the drives a few at a time all Segate recertified it seems to be the sweet spot in price for me. I had to upgrade and rebuild things several times. Your video was just like my experience switching OS, FS, etc. I had endless drives/arrays just dropping out, mostly on startup. I tried Fedora, Centos, Open Suse, Suse JeOs, and Ubuntu Server all let me down for one reason or another. I tried them with various shares, raid arrays and file systems; plus not all would run my app. I ultimately got it working with Ubuntu workstation and the Ubuntu share - no samba. I'm not happy with ZFS. I had to kill the swap and add more RAM (which meant a new motherboard) to keep ZFS cache from crashing. I solved the dropouts problem by putting the drives really close to the host board and using short/expensive data cables that are all the same length. I'm using a very old Athlon FX-8300 8 core and 64 gig of Ram. I found a great last generation Adaptec 52445 raid card new old stock. I had to install 2 power supplies and rewire one to all molex to get enough amperage on the 5 volt rail. New 1200 watt supplies have plenty of 12v but almost no 5v power. I also upgraded to 2.5 gbps network card. The write speed is NOT stellar. With Raid0 it goes real fast at first 450mbps filling all that cache, but slows down to about 150mbps. With a single JBOD I only get 130mbps, two drives at the same time still go 130 each, and I can transfer to 4 drives at the same time before it bogs down the network and write speed drops to 70 each drive or 280 total. I already got 4 sas expanders and plan to continue adding drives (and power supplies) up to 2.5 PB. My box is an old IBM 2401 tape drive converted to rack space. I yell at the You Tube screen, not my computers. That's not true I also yell at my computer at work (it's windows).

Hu, I know that modern cases have that 1 stud so you can place your motherboard in on the stud which makes it easier to align the rest of the screws, but even then every motherboard I have installed has had 8 - 9 screw holes, sometimes there is a heatsink or something in the way of having all 9 screw holes, but 8 is the minium I have seen, this is only for full ATX though not ITX / mATX.

Jeff, you have carved yourself a niche channel in an overcrowded tech community, taking the Pi to new heights in every video. Keep it up. Loving every video. I'm left astounded on the Pi's capabilities and untapped potential.

Amazing content as always, keep up the great work!

Ive always wondered if there was a way to make a external ram board like hp has one that adds 4 ram slots on a pcie. Ive ran into issues of bottlenecked performance not because of cpu but because ram capped out. The pi has only max of 8gb so i would assume max speed on drives could only be met with maybe 6 to 10 drives at most. If you were to add an additional 128gb i wonder if that would help out. Plus the raid cards you had i couldnt tell if they had their own memory or passthrough.

One thing I saw you doing when wiring up the NAS was that you connected the molex adapters to two sata power connectors on the same line. If the psu has another line, try connecting to that, as each line can draw a limited amount of current and there might be an issue there. Then again, the issue might be anywhere else but that's a thing you can easily try

My NAS is a pi4 with a desoldered USB chip to expose the PCIe bus. It's connected to a PCIe switch(to improve transmission and prevent crashes) and then to a cheap ASMedia SATA controller. The kernel is also patched to force PCIe gen 1 to prevent crashes(this is probably the same thing that happened to you in the video btw). PCIe gen1 is still faster than gigabit so it doesn't matter. Over samba or NFS I can get the full gigabit speed even on large data transfers so no bottlenecks there. Would I recommend this setup? no. Does it work? hell yeah (longest uptime was like 90 days or something and then a power outage killed it, I need to get(or more likely make) a UPS, I know). If anyone wants photos lmk

Hey! 45 Drives is here in my home town!

Even before doing a raid or zfs test; I’d have run a single drive test (either benchmark or simple linear read/write). Loop that 60 times and see success. Then repeat with two drives in parallel and loop 30 times. Redo with three in parallel 20 times, etc etc. When you start seeing failures you really will see the cause-effect point. There is technically no reason why this won’t work with 60 drives - if you ignore performance. Any bugs that are exposed that can be fixed will simply improve the base users world. This is an awesome test that pushes the RPi and kernel to the limit. Making this work at that limit helps all of us just running one drive. Plus, the errors you saw, as bad as they were, should somehow restart the drive (without a reboot).

@JeffGeerling

When those errors occurred, the HBA reset itself and the drives always came back-at least 15/16 of them! That was one concern from the Broadcom engineer I spoke with, and the reason he really wanted me to run the latest firmware.

Were they taking ab big chance? What if Jeff had proved you could do it all better with a PI? Hahaha.

@@wayland7150 Not much of a chance. They are well aware of the performance of their product, and the limitations of a Pi.

I have a Pi running RAID1 with 2 External SSDs and on times I have to reboot as it seems to forget that the disk exists. That's Pi 4 and Samba and a Window share. So to get as far as you did its amazing.

I work with a 100x drive server similar in design that uses 8 fans. I am sure with the pi/limited activity those 2 fans will suffice but withe the stock internals I doubt the drives will be reliably cooled below tdp. You would need to keep it a room controlled to

As a St. Vincent fan, I'm calling it "Pietabyte" whether anybody else does or not.

Next step: 3.14PB on a PI

The real impressive thing ist that he was able to get a pi compute module 4 I am trying to find one now for almost a year but the only place I even found one listed was on Amazon in the us, it is sold out since then, here in europe I did not even find a seller who listed it

This guy is the only human capable of winning in a debate with Data from star trek.

How many times did you recompile the kernel?

I'd almost be interested in seeing each raid card assigned to 1 PI and then them clustered together.

Hi - im interrested in the "working mat" on your table - where i can get this? And thanks for the entertaining clips!

The linus video is literally in the other tab on opera. I was bouta watch it next.

I would really like to see you build a cluster based file system like gluster or ceph, run that on a pi cluster with 2 to 4 drives per pi, then show performance

If lsblk starts to run out of letters and shows drives as "sdaa, sdab, sdac" etc. you know you have a data hoarding problem.

What PCIe Gen (e.g. Gen3) does the CM4 carrier run? I have some experience trying to push FPGAs over those crummy 1x risers, and almost always had to drop to PCIe Gen2 or even Gen1 to maintain signal integrity over even the shortest USB cables. I'm curious if it would be more stable, at the cost of being even more painfully slow on the upper end. Edit: Oh wow just saw the follow-up video to this, and sure enough, dropping to gen2 improved stability a bit, and dropping to gen1 seemed to make things solid. Would not surprise me if just about all of it came down to the riser and USB cable carrying PCIe signaling.

Is it possible to build a NAS with 4x 3.5HDDs with each just connected to the USB ports? I want to use Linux ZFS. Is there any major problems other than being slower than direct sata? like poor power management of the hard drives or something?

Would love to see this with a RISC V processor

"I grabbed a small piece of cardboard to insulate the boards from each other. At least temporarily." Yeah. Sure. I think red shirt Jeff was trying the break back into the room.

You can see red shirt Jeff is actually in the room with Jeff at one point in the video.

Wow. crazy stuff :D

I built my first datahoarder set up using nothing but 8tb SSDs XD a whole bunch of them. solves the issues of "spinning" in an easy way

They must really trust you to borrow $35k+ worth of disks

How many days until "I lost all my data" video? :) But hey, if it summons Wendell from L1Techs, it's kind of a win-win.

Yay! Tiny computers doing huge things!!! 🔥🔥🔥

I am afraid someone addicted to this work is called a petaphile person! 😱 But great, that there are people doing these kind of projects!

dang, fedex unboxed it first huh. not surprised

You had me @ hard drives. *giggle* Subscribed.
