Adding reliable storage space to a laptop computer - based system

I've lately asked an as - yet - unanswered related question.

My inquiry below is a bit various : I need to know the most effective means to add storage space to a laptop computer - based system without giving up power performance or "worldly performance". By the last, I suggest anything which would certainly create the storage space components to wear away extra swiftly than essential. The major instance I can consider is if spindown takes place also occasionally, or probably additionally as well regularly, the life-span of the drive in inquiry might be lowered.


Currently I'm attempting to identify just how to get an HP Simplesave 2.5" drive to act sensibly well. Clearly this is not the optimum selection ; it was a boxing week sale which might wind up being repossessed.

Numerous examinations on it making use of hdparm appear to show that it is not making use of the value of the -S parameter, which is intended to establish how much time it waits to rotate down. Rather, it appears to rotate down after 10 secs if the -B alternative is readied to 127 or much less, and also after an extended period of time, or probably never, if it is greater. I state this mostly due to the fact that I'm not totally encouraged that these instructions will certainly often tend to function as man hdparm claims they need to also on drives placed in correct USB units. The guidebook does state that more recent units often tend to sustain these attributes.

bottom line

The system often tends to function primarily as a web server, though does see periodic usage as a media box. It might get put on hold periodically, or might wind up being powered on and also energetic (though still) for months.

I would certainly such as to have readily available the very same type of power management capability that I would certainly get with an inside - placed HDD in a desktop computer (or rack - placed?) web server. This consists of rotating down and/or resting the drive when the web server is put on hold.

So I would certainly such as to recognize the most effective strategy to locating a reliable storage space remedy. Are particular brand names of units much better for this? Is it essential to make use of a 3.5" unit, or at the very least one that is powered independently from the USB line, to get correct power management centers? Or would certainly I have make use of a complete NAS system for that?

USB drives have a chipset that transforms USB mass - storage space - tool regulates to IDE or SATA commands, which the drive after that obtains. Economical chipsets (which are the bulk, I visualize) do not hand down commands appropriately to the drive that aren't straight pertaining to reviewing or creating information from the drive. You are sort of at the grace of that hardware with USB units.

Seems like just one of the most substantial little the that - S value is reading by the drive or controller (off (> 128) = power conserve setting, on (< 127) = high efficiency setting)

You could improve attribute assistance if your system has an eSATA port. eSATA talks straight to the drive so there is no "translation" or linking of commands required.

In my point of view, the most effective point you can do to make certain a lengthy life for a disk drive is :

  • tidy power to the system, get a power - conditioning UPS
  • maintain the tool in an area with a constant ~ 70 level temperature level and also reduced - moisture
  • decrease powering them on and also off, yet do power them down otherwise being made use of for an extensive amount of time
  • back-ups, back-ups, back-ups.

I would certainly claim place your cash right into a UPS and also an additional drive for back-up. Do a RAID point if you such as.
