HDDs are definitely not making performance or capacity improvements of this order.

A 15TB drive you can completely re-write every single day of it's five-year warranty life and not expect a failure.
Samsung ships the world's highest capacity SSD, with 15TB of storage
Now we just need better interfaces in our PCs to handle the 12Gb Serial Attached SCSI (SAS) interface.

Seagate caught up pretty smartish

Just a month or so later Seagate has a 10 TB Helium-filled HDD to rival Western Digital's.
I'll be on the lookout for a comparison!

A 10TB Helium-filled Disk-Drive WITHOUT shingling

I'll bet you thought I was done here, hey? No, just very busy this last year.
This seems like a sufficiently significant bit of news to warrant a quick mention though.
WDC's shingle-free stocking filler: A 10TB helium disk drive
The spec' is pretty amazing and available in PDF format Here.
Here's a quick rundown -
Western Digital Corporation (WDC) has updated its Ultrastar He8 to the He10, providing the same capacity as the shingled HGST Ultrastar Archive Ha10 announced in June but without the shingling, meaning standard write speeds.
Compared to the He8 it has 25 per cent more capacity, and WDC says it has a 56 per cent lower watts/TB rating than traditional air-filled HDDs, a 2.5 million hours MTBF (mean-time-between-failures) rating, and a five-year warranty.
The drive has a second-generation, dual-stage HGST Micro-Actuator to enhance tracking accuracy and reliability in multi-disk enclosures. It is said to be "drop-in ready for all mainstream enterprise capacity applications." This presumably, partly at least, explains why WDC can now get to the 10TB capacity level without having to shingle (partially overlap) tracks and incur the penalty of slower rewrite speeds.
It rotates at 7,200rpm and is a classic capacity-optimized drive, with a 256MB cache and 249MB/sec sustained transfer rate. The previous He8 had a 205MB/sec sustained transfer rate. It can have a 6Gbit/s SATA interface or a 12Gbit/s SAS one.
There are Instant Secure Erase (ISE) and Self-Encrypting Drive (SED) options and the disk is built for 24 x 7 operation. To increase reliability, it retains a previous firmware version for safer firmware updates.

I think that Santa could probably fit that in his sack without any problem.

Python 2.x.x AND Python 3.x.x on Windows

If you need to run both Python 2 AND Python 3 scripts on Windows, this is good to know -

Less than 1 month later!

So, 8 Terabyte was the newer hotness in August, now at the start of September HGST has a 10 (Terabyte drive ready! (But I still hate Shingled Magnetic Recording)
Whopping 10TB disks spin out of HGST – plus 3.2TB flash slabs

4 months later

So, 6 Terabyte was the new hotness in April, now at the end of August Seagate has an 8 Terabyte drive ready!
That 8TB Seagate MONSTER? It's HERE... Have a look (sans specs)

Just when I plan to catch up...

Most of my machines have 1TB drives and 2TB external backup drives.
I was thinking about moving to multiple Virtual Machines running on the desktop PC with a 4TB drive to hold the VMs and another for backups.
This means losing having the SSD as Windows 7 boot drive unless I get a bigger SSD for Windows 7 and the Hypervisor and keep Linux machines on a HDD.
Still, as of today I know what the server needs for VM backups - Seagate brings out 6TB HDD
Get a datasheet here (PDF).

Ten Songs Challenge

Well, I know at least 10 good songs that I always want to have around.
Finding near approximations to my home versions took a little longer, but here (in no particular order) you go!

Everlast - Ends

Massive Attack - I against I

Jean Elan - Where's your head at

Pink Floyd - Comfortably Numb

After Midnight Project - Take Me Home

Booker T. And The Mg's - Green Onions

Phil Collins - In The Air Tonight

M.I.A. - Paper Planes

Eddie Vedder with Nusrat Fateh Ali Khan - The long road (My version is 16:37 long)

Ng Pei Sin - Misty Heart (From my Mod collection, an XM actually)


I could easily do 100 if I had the time! Torley Wong and Madonna very nearly made the list for starters!

The Omega-3 and B12 Myth

It looks like being vegetarian is good for health, but not necessarily longevity for many practitioners.
A Vegan explains some worrying study results for Meat-eaters, Vegetarians and Vegans.
It's a worthwhile 1 Hour 15 Minutes of nice explanations and tips that we can all use -

So, What foods are good for you?

Eggs? - Not really

Avocados? - If only

Coconut Oil? - Hell No

Garlic and Flavinoids? - at least vs Fish and white meat induced cancer in breast cells

Acia Berries or Pomegranate Juice? - Finally, a pretty positive result (if you can actually get them)!
