I was about to use it as a boost drive xD Muy other drives are 10 years old xD why shouldnt I?
Well, I found this
I wouldn't look at desktop and NAS hard drives as equals. It really depends on your intended purpose for that particular new HDD you're looking for. The WD Red can be used as a regular desktop drive, however, it's okay to do that only if you need massive secondary storage for your data. Otherwise I wouldn't consider using the drive for OS and run demanding software programs from it. The WD Red NAS drive uses IntelliPower RPM which is a fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver significant power savings because, after all, it's designed to run in 24/7 RAID/NAS environments. This basically causes the drive to spin down occasionally (when not accessed), so I wouldn't use it for booting on its own. The HDD is also equipped with a specific NASware 3.0 firmware that delivers a lot of benefits in terms of performance, but unfortunately, they are rarely noticed when used as regular secondary HDD, so it does look like any other massive desktop storage drive.

Depending on the purpose for your storage upgrade, there are different drives out there that are designed to deliver what you are looking for. If interested, here is a link to our desktop HDDs with a short description of their purpose and capabilities:

Thats why, i would get a 240gb SSD, 80 bucks more,
