we're getting smaller right now.
miniaturization.

simply from sands. you can get silicon.

queries all about solid state device, feel free to ask..

sample:

unsay gamit sa solid state?
tubag: kuan, kanang daghan.
1. optical HDD, replaced by Solid State Storage Device
advantage: lighter, power efficient

Flash drives
Most SSD manufacturers use non-volatile flash memory to create more rugged and compact devices for the consumer market. These flash memory-based SSDs, also known as flash drives, do not require batteries. They are often packaged in standard disk drive form factors (1.8-, 2.5-, and 3.5-inch). In addition, non-volatility allows flash SSDs to retain memory even during sudden power outages, ensuring data persistence. Flash memory SSDs are slower than DRAM SSDs and some designs are slower than even traditional HDDs on large files, but flash SSDs have no moving parts and thus seek times and other delays inherent in conventional electro-mechanical disks are negligible.

Thumbdrive in a hard disk casing... not necessarily optical HDD, as a matter of fact Optical HDD is different from SSD.

whats an optical HDD?

the only optical in PCs that i know are ODD - optical disk drives, which is not a SSD.

OK, open a defective HDD. we'll see a shiny surface. just like DVDs. it's the same principle by the way.

From what I know about Solid State Physics. Solid State Devices just pertains to devices that use CMOS technology or silicon wafer technology. Since it is Solid State Physics that allowed this advancements, then why not call it solid state devices. hehehe! You guys are right, they are indeed more advantageous but expensive. hehe Flash memories are really awesome because you don't need power as you pointed out. hehe! If I remember well, the reason for this is quantum confinement of charges in a small region of matter only electrically accessible by applied voltage.

Just to contribute, I would like to mention the people responsible for spearheading solid state devices especially on magnetic hard disk drives. Albert Fert and Peter Grünberg who both won the nobel prize in physics in 2007 discovered a quantum mechanical effect called giant magnetoresistance. This discovery basically allowed increased the HDDs which is really awesome. hehehe

thanks fritz..

we'll hope to learn from you soon..

very informative..

lols! i open a hundred of drives bro. What you are talking are not SOLID STATE. They are our ordinary drives that runs on a magnetic platter. The head is optical base that float in the platter when it spins 5200/7200 RPM.

SSD are chip base. No mechanical parts as far as access is concern.

Im a data recovery engineer bro. I manage to transfer Head to another drive.

FYI: did you know that the disc on your drive are glass coated with metallic substance? I think its platinum.

Yeah, you are right. hehehe! They are magnetic and use GMR heads. Information is stored via magnetic alignment. In a way, they are still solid state because optical based devices literally involve optics. hehe! but indeed, SSD pertain more to the newer literally SOLID devices without moving parts as you mentioned. hehe

OT: i agree w/ kebot,
DVD & CD are optical media formats and to read/write on this, lasers are used; optical media & lasers are both related to optics.

platters - the shiny thing when you open HDD just like DVDs, are very different. they use magnets. magnetic data & magnetic medium.

i'll say it politely, i think its wrong to say optical HDD.

what kind of HDDs sir?

basically, HDD use optics to read and write.
DVDs also.

it's metallic kebs. i donno if it's platinum.
