Naked Security: HPE warns of impending SSD disk doom

HPE warns of impending SSD disk doom
by Danny Bradbury,

[HP Enterprise] released a critical firmware patch for its serial-attached SCSI (SAS) SSDs, after revealing that they would permanently fail by default after 32,768 hours of operation. That’s right: assuming they’re left on all the time, three years, 270 days, and eight hours after you write your first bit to one of these drives, your records and the disk itself will become unrecoverable.

All I can say is, "d'Oh!". And if you are using one of these SSDs, get the firmware updated as soon as you're able to.

Translation of Gikfun's EK1885 kit

1 comment:
I've recently taken an interest in electronics and decided I wanted to try my hand at soldering surface-mount devices (SMD) to circuit boards. I've seen many YouTube videos (see links below) on how to do this, but my practical experience has been minuscule, involving only a few single-chip breakout boards.

In order to gain a bit more experience with SMD soldering, I searched Amazon for any SMD practice boards. There aren't many, but there are a few. I selected the Gikfun EK1885 kit (Amazon link), because in addition to being a board to practice on, half of the board actually does something - it uses a timer and a counter chip to make a group of LEDs flash in a simple pattern.
