I was just curious, because if you don't have backup of the drive (RAID or
whatever) and you store a lot of data on the drive, this is becoming a
problem.
Just wondering, what is the advantage of red vs blue
in case of WD SSD? I
know that in case of the mechanical drives WD Blue has a feature that
spins the disk down after 8 seconds of inactivity while for the Reds it
does that after 300 seconds (although it can often be changed) along with
vibration reduction. But for SSD, what is the advantage?
Afaik Blue is intended for Desktops and Red for NAS (especially the Red NAS
version)
You will gain
on disk speed (as Nik mentioned probably 4x), so it is
good idea. I only wonder why you would take such large disk.
I decided to go for the largest size that still allows me to boot from
(legacy) bios, without the need to create a GPT label (although I know it
is possible to boot a larger disk from BIOS, but I want to keep it
simple). Sometimes I copy a lot of simulation trajectories, so it may help
having extra space.
One thing that keeps me away from mechanical hard
disks is that a lot of
the 2.5" disks come as SRM instead of CRM. I also like to turn off the
head parking (spinning down) feature that causes the load count to
increase quickly on the OS drive, but this is sometimes tricky.
Well ... the spinning/mechanical disks are becoming something like the tape
drives from 15y ago. Few years ago I updated all the drives (some were 10+y
old) and I use mechanical in RAID only for the movies and documents. The
rest is on SSD. Both types are WD
Model Family: WD Blue / Red / Green SSDs
Model Family: Western Digital Red
Device Model: WDC WD20EFRX-68AX9N0 (old drives being decommissioned)
Device Model: WDC WD20EFRX-68EUZN0 (old drives being decommissioned)
Device Model: WDC WD60EFPX-68C5ZN0 (since last y. replacing 3x2TB above)
Device Model: WDC WDS100T1R0A-68A4W0 (SSD 1TB)
Device Model: WDC WDS200T1R0A-68A4W0 (SSD 2TB)
AFAIR EFRX is CRM, but could be I am wrong.
