How to expand your NAS with USB drives – and why it’s not always a good idea

The image shows a black ASUSTOR NAS device in the foreground, which appears to be a Network Attached Storage device. The background features a blurred-out white surface, and there's a subtle blue light source emanating from the bottom, possibly from LED strip lighting. The overall setting looks like a product photography studio setup, indicating a professional product shot.
Expanding the capacity of even the best NAS is simple. Fill the enclosure with as many drives as it supports, and add an external enclosure once the primary system is fully populated. Larger drives can replace smaller capacities as they reach their end of life, but there’s also the possibility of using USB drives to expand capacity. Whether or not you should do this is a different matter altogether.

In my own case, I do actually use the USB interfaces on my home server. But I have USB-SATA connectors going to each 4 TB hard drive. At 2am every morning, the server does an incremental rsync backup from drive 1 to drive 2. So I don’t sit with the drives running all day long in a RAID configuration. For me, it’s working fine right now.

#beans #storage
I store beans in glass jars.
- Internet. If you want to store dried beans for longer than a month, put them in an airtight storage container, such as a mylar bag or a glass jar. Keep the beans in a cool, dark, dry place. They should last three years in the container.

5 reasons you should replace your regular SSD with an NVMe if you haven’t already

Close up view of part of a computer motherboard showing a M.2 slot made from white plastic with fine pin-hole size holes along its length on each side.
It’s a pretty established fact that adding an SSD to an old PC is one of the biggest improvements to its overall performance. But what about if you already have an SSD but are tempted by the recent price drops of NVMe storage? Will that upgrade bring a similar boost to performance, or is it something you could leave until you next buy a new computer? Well, while it won’t bring the super speed-up of moving from an HDD to an SSD, putting NVMe in your computer does come with some worthwhile benefits for the upgrade.

Some quite valid points made in the linked article. Something I did not think about was the SATA connector itself limits throughput speed vs a PCIe connector.

But for many of us who still have boards with only a single M.2 slot connector. In my board’s case, using that slot would mean two of my SATA SSDs I think being disabled. But for my future motherboard purchase, I’ll certainly be looking for multiple M.2 slot connectors on the board. Most of the clutter of cables inside my case is due to the many drives connected in there.

A petabit of data can be fit on an optical disk by storing information in 3D. They say that's 125,000 gigabytes on a single DVD-sized disk.

"Optical disks like DVDs and Blu-rays are cheap and durable but can't hold much data. Until now, optical disks store data in a single layer of information that's read using a laser. Well, you can kiss those puny disks goodbye thanks to a new technique that can read and write up to 100 layers of data in the space of just 54-nanometres, as described in a new paper published in the journal Nature."

How do they do that? The research paper is paywalled but the abstract says:

"We develop an optical recording medium based on a photoresist film doped with aggregation-induced emission dye, which can be optically stimulated by femtosecond laser beams. This film is highly transparent and uniform, and the aggregation-induced emission phenomenon provides the storage mechanism. It can also be inhibited by another deactivating beam, resulting in a recording spot with a super-resolution scale. This technology makes it possible to achieve exabit-level storage by stacking nanoscale disks into arrays, which is essential in big data centres with limited space."

Femtosecond lasers, eh? How much is this reader/writer going to cost? I have a feeling it won't be showing up at Micro Center any time soon. But might be good for Google, etc, to back up the massive amounts of data they have in their data centers.

Disused mine in Finland is being turned into a gravity battery to store renewable energy

The firm has developed an energy storage system that raises and lowers weights, offering what it says are “some of the best characteristics of lithium-ion batteries and pumped hydro storage”.

When there is excess power - from wind turbines on a windy day for example - weights would be winched up the Pyhäsalmi mine’s 530-metre auxiliary shaft. To generate energy, these weights can be released turning the winches into generators creating either a short burst of electricity or a slower trickle depending on what is needed.

The gravity energy system would be able to store 2MW of power and integrate into the local energy grid.

30 TB hard drives coming. Moore's Law keeps cranking. Thanks to something called "heat-assisted magnetic recording (HAMR) technology". It works by temporarily heating the disk material just in the spot that's being written, and this allows writing to smaller regions at higher densities. It's tricky to do but apparently Seagate has mastered the technique. Apparently this technology was announced last June but volume production hasn't fully kicked in yet.

In need of more space?

On many notebooks it is possible to install several storage devices.

One way is to use an mSata drive in the wwan slot, if it is not needed for a modem (or if a modem is needed, it's possible to use an external usb modem instead).

It might be also possible to use a wifi card M.2 slot for storage: With an adapter NVMe drives can be connected.

And for machines with an express card slot, there are express card to NVMe adapters available.

So it's possible to have a storage device in the wwan slot, in the wifi slot and/or in the express card slot.

There are also dual slot adapters available, which make it possible to install two M.2 NVMe storages (instead of having one SSD).

Besides these solutions there are probably even more ways to install more storage devices on (older) notebooks.

Does anyone know if there is a way to use one slot for two 2,5" SATA drives (via adapter)? Did not see such a setup yet.

My Solar Exploits

Not a lot to report. Had a multi-day overcast and snow and the batteries bottomed out and the system automatically switched to grid power and started charging the batteries. The confusing thing is that it made the switch at a different point and in a different manner than the first time. No big deal, but will need to figure out why and maybe adjust some parameters.

This bottoming out puts a small glitch in my hopes of running a full month just from Solar/Batteries but still hoping to see a significant difference in the monthly Xcel bill...should know in a couple of weeks.

Also moved my panels around in the backyard to hopefully better take advantage of the winter sun. Moved one set back against the rear fence where I can leave them at a more productive angle. We'll see.

Enjoy!
