Hard Disc Drive

Role and abilities

Hard Disk Drive is a PIU with the primary function of recording information and data. Recently, their design has been rendered significantly less valuable thanks to the discovery of SSD, a SU that performs HDD’s tasks with almost unrivaled efficiency. HDD rarely performs tasks alone anymore, mainly when the other units in SSD's binding are otherwise preoccupied, or if the task doesn't necessarily have much complexity.
Similarly to an actual hard disc drive, HDD is nonvolatile. Assumingly due to this fact, they are unaffected by the Dreamcatcher Staff and openly dislike PSU. These similarities also include constant movement, as the disc on HDD's chest is constantly moving, along with him almost always having some slight physical movement elsewhere; both of which conttribute to HDD not exactly being the quietest unit.
HDD possesses the state-of-the-art wing storage system originally developed for CPU, having an additional 2 wings on her back.
Being one of the heftier units, HDD doesn't have the capabilities to move as speedily as other units, however they do instead have more physical power.
Being the long-term memory storage and one of the first HPFMU models (excluding revisions to physical appearance), HDD was intended to have better memory than other units. However, an unknown glitch has caused an alternate affect which causes them to quite literally remember everything, possesssing a seemingly infinite amount of storage. Along with this comes a malfunction which results in HDD's memories "bleeding into" his reality, creating delusions and short periods of extreme disorientation.

Personality

Since the discovery of SSD and the growing neglect for HDD, they have experienced significant changes to his personality and demeanor. Changes include increased aggression towards staff, isolating behaviour, less tolerance for other units, a more tempermental disposition in general, and paranoid behaviours. This also significantly sped up the progression of HDD's felis adomania, which is partly to blame for certain behaviour changes such as the paranoia. Before SSD, however, HDD was seen as a dependable, almost parental figure to most other HPFMU; being somewhat like Graphics Card or ODD in nature. They had the tendency to playfully joke with or harmlessly tease other units, however not in a way so as to actually offend or hurt anyone. All in all, HDD had been very reasonable, calculated, and thorough, being a reliable unit to go to for help or advice. It was the loss of their "realistic optimism" which is what caused them to devolve into her current brutally honest, stubborn, and obsessive demeanor. HDD would previously pride themselves on their organization, however now they operate in more of an "organized chaos". However, despite this and the multitude of other personality issues they've developed, HDD holds others to exceedingly high expectations and openly looks down on them if they fail to meet said expectations, coming off as quite discouraging. HDD has also developed multiple odd habits, such as obsessively theorizing and taking notes on everything, which they will occasionally follow others around to do so despite others expressing discomfort with this.

Interpersonal relationships

Since their personality change, HDD's relationships with other units have deteriorated significantly. One of their few positive relationships is with Webcam, whom they are quite close with, spending a majority of their time with her when not alone. This is likely due to the fact that (in a general sense) Webcam has little relation to other Internal Units, what with being a relatively new and being an AV Unit. Henceforth, Webcam also was not fully developed by the time of SSD's discovery, and has built a relationship with HDD without having known them before their personality change. As a result of HDD having significant resentment towards SSD, they've developed very conflicted feelings towards CPU and RAM, who help to make up the binding. HDD is particularly short-tempered towards the two, determined to prove she doesn't need them, despite knowing that it's neither his own nor RAM or CPU's fault for HDD being "replaced", and that SSD is simply more efficient. Additionally, HDD was previously fairly close with both ODD and Graphics Card, growing more distant as time went on. HDD's most noteable relationship was with GPIB, whom they were by far the closest with, in fact, it had appeared that the two had been romantically involved. This has been confirmed by other units which had been active before GPIB's decomissoning. HDD had looked up to GPIB admiring her for her confidence. It is speculated that HDD was originally the one to inform GPIB of some classified info, which sparked her investigation and devolvement into Felis Adomania. As a result, it was after GPIB's public decomissioning was the original point where HDD began to develop slight behaviour changes. This is another reason as to why HDD gets along with Webcam so well, as, aside from her also being a Memory Unit and sharing a passion for note-taking, she reminds HDD of GPIB. So much so in fact that in tandem with HDD's memory malfunction, they will have short delusions where they genuinely believe that Webcam is GPIB and will treat her as such, becoming extremely disoriented after the fact. HDD openly dislikes GPU, VRAM, PSU, Microphone, Partybox, and Antivirus. Antivirus making them mildly uncomfortable, Partybox for an unknown reason, PSU due to their lack of emotions and emotional awareness, Microphone for being "too energetic" and GPU afor being "a boisterous narcissist" and VRAM for being "too pretentious".
