Intel SSD 600p Series NVMe SSD Temperatures: ensure you cool it properly even for moderate use

Posted by jpluimers on 2018/04/30

A short while ago, I installed a pair of 1TB Intel 600p NVMe SSD devices.

Performing a straight rsync backup of some 100 gigabyte of data managed to shutdown both of them: the throttling was so much that VMware ESXi lost the volumes on it and showed “Permanently inaccessible device”.

I was quite surprised as the initial reviews did not mention any temperature problems, but apparently there are.

Since then I’ve put a 120mm fan near to it which made the problems go away, but it still every now and then jumped to over 60 degrees Celsius.

Later I “fixed” it in a better way for cooling getting the idle temperature around 30 degrees Celsius and heavy duty temperatures around 40 degrees Celsius:

I did not have to mount any M.2 heatsinks on them yet; they probably won’t fit under the fan anyway

Backup & Sync: The ridiculous steps you need to move the Google Drive from the C: drive to the D: drive

Posted by jpluimers on 2018/04/27

Unlike for instance DropBox, Google Backup & Sync does not allow you do move the Google Drive location in a one-step way. You have to go through below ridiculous steps to move it around yourself.

A comment on G+ indicated I should try Insync. Not free, but way more stable and more features.

Insync adds Google Drive functionality to your Windows, Linux and mac OS desktop. Sync, backup, edit and share files easily with one or multiple accounts. Team Drives syncing for G Suite accounts now available! Try Insync free, no credit card needed.

More old Apple documentation

Posted by jpluimers on 2018/04/27

It’s been a while back, but these are part of bitsavers.org:

  1. [WayBack] http://bitsavers.trailing-edge.com/pdf/apple/service/PN_072-0213F_Apple_Service_Technical_Procedures_Peripheral_Interface_Guide-Jan_1991.pdf
  2. [WayBack] http://bitsavers.trailing-edge.com/pdf/apple/service/Apple_Service_Source_LaserWriter_Pro.pdf

I expect few people to still have a functioning Apple LaserWriter Pro as – despite them bing very solid devices – having them last for almost 25 years is quite a feat.

But I do know many people have machines from the Apple II through Macintosh II era, and that’s what the first manual is about. Some of the contents:
