4 way HDD switcher

[arg-ist]

_____________________________________________________________________________________________________________________

Hi
As a new member , ı want to beginn with a mini worklog

I know most of my friends are using 3-4 HDD s as storage. Working all of them creates problems;

Life of the HDDs ,heat problems and noise…

At a Project ı wanted to use an HDD switcher for 4 HDD s. but ı could find only for 2 HDD s.

I made an HDD switcher for 4 HDDs.

A 5.25 box with 3mm plexi

Holes for switches and leds on the front cover and holes for molex at back with lazer cut. Letters laser engraving.

All wirings on a little pertinax

Before closing the box

Added 4 leds and 4 sleeved sata power cable.

Finished..

I can select 1. HDD

Or one of 2nd -3 rd or 4 th HDD ..

I can make combinations of f

FİNAL

What are you trying to accomplish by doing this? Keeping drives spinning doesn't kill them nearly as quickly as spinning them back up regularly as it requires a lot more work and power to get something not moving up to speed than keeping something at a particular speed. The only good reason I see is to reduce heat and power consumption but those are non-issues if you just keep the drives spun up. To keep 5 drives and 2 SSDs active costs something like 20 watts, it's really not a lot.

that is the reason; my first sentences...

they are used as storage . it is not necessary to work with all them . I can select the necessary one..

right but the point is you can just plug them in and select the necessary one anyway, and not have to power them off or on independently, ever. there is simply no technical reason to do this, as the problems you listed are minimal compared to the damage eventually caused by turning a drive on or off multiple times every day.

that being said, you did an awesome job. very good work I just disagree with the necessity of it.

You summed up my feelings as well, even if it didn't come out that way. I have 9 spinny disks in my house, 5 in my tower, 4 in my server and the only time any of them power down is if the machine turns off. The 4 in my server all have over 30k hours on time and they're all going strong still. The drives in my tower have between 10k and 4k on hours but I treat them the same way; always spinning.
