Spinning Disks: the smallest hard drives compared

[@AiOinc1]

0:38 3.5" SL drives like you show here didn't become common until the early 90s. The 3.5" drive that was introduced in 1983 was the Rodime RO252, which was HH, or double the size of that drive. It displaced half height 5.25" drives which were introduced just the year before by Microscience International as the HH-612. Only two years before that, the Seagate ST-506, the first 5.25" hard drive at all was introduced. The ST-506 replaced the IBM 62PC Piccolo of 1979, which was an 8" drive ,the first of it's kind. Technology during that era was moving scarily fast. The Rodime RO252 is a 10MB drive, just 3 years earlier a drive 4x the height stored half the data. 0:52 The 2.5" drive introduced in 1988 was the PrairieTek Prairie 120, which was twice the height of the Toshiba you showed. It was the smallest production hard drive in the world at the time of it's introduction. Thinner drives came a few years later, but this "Full height" 2.5 inch form factor was still relevant for enterprise applications until the mid 2000s. 1:21 The first 1.8" hard disk drive was the Integral Viper, in 1993. It was a PC Card, and they were popular for mobile data storage long before the iPod hit shelves. 5:50 The IBM Microdrive isn't "Basically" a Compact Flash card, it IS a compact flash card. It was intentionally designed to be interface and socket compatible. Most devices which support one will support the other. The Microdrive hit production in 1999 and it was the world's smallest production hard drive. You could get original Microdrives in capacities of up to 340MB on a single 1" platter. 11:28 The Toshiba MK4001MTD and MK8003MTD, the smallest hard drives in the world. 4 and 8GB, respectively. I believe they really do use an SD card interface.

Wow, your specific knowledge of early drives is amazing. I really appreciate hearing these details. One day I'm going to revisit the 1" drive in a video of some sort. Unfortunately I have already recently made a video about iPod and 1.8" drives. But I didn't know their real history. I do research these things. But it's hard to find the sort of detailed knowledge you have. Thank you!

[@bcwbcw3741]

@@JanusCycle You do know that with a fly-height of about 100nm, opening these drives outside of a cleanhood means they're dead soon? The 2.5" drive you show operating is actually retreating to the ramp repeatedly because it isn't able to land correctly. The first IBM microdrive was a 1" drive, I think you have the order reversed. At the time of the 1" drives introduction in the ipod, it wasn't possible to fit flash memory of the same capacity into that amount of space. That changed within a year or two.

[@bcwbcw3741]

@@JanusCycle Every time you flick the arm so the head slides off the load ramp and splats on the disk I wince. I was wrong about flash density - it took about 6 years to match the 1inch disk but I wasn't following it anymore as IBM had sold the hdd business to Hitachi because single 3.5" platters where holding so much that backup and access times were suffering and there HDD's were becoming a commodity with less value from increased density. For the previous 20 years, HDD data density had doubled every 1.8 years. The first 1" drive had data tracks spaced about 10 microns apart so there were about ten thousand data tracks on each side. The radial position was servo controlled to about a 0.1 micron as the disk spun.

Fascinating. I never knew that such small mechanical drives were once commonplace in commercial products. I remember visiting the Science Museum decades ago and marvelled at the huge pioneering hard drive, which was cut away to expose some of the mechanism. The drive must have been 24 inches in diameter! When the company I worked for in 1978 we got our first word processing system with terminals on desks and a huge drive unit in a special room down the corridor. The diameter of the drives in that unit was around 14 inches, I reckon, and the drive had a capacity of 40 MB. The terminals had local 8 inch floppy drives, too. That's when I started to become interested in computer programming.

The large external SCSI enclosure housed a 2.5" SCSI interfaced HDD with an adapter to the normal "Centronics" style external SCSI connector. It dawned on me at the time that it wasn't an economical way of creating an external SCSI hard drive. When manufacturers stopped making 2.5" SCSI hard drives I recall Apple laptops ending up using a regular 2.5" IDE HDD with a SCSI adaptor board! So much electronics! I found a solution to the lack of drives though - certain printers used a 2.5" SCSI hard drive as an internal buffer - so I bought as many of those kits as I could afford, I ended up using them all in Apple laptops!

I remember when they put spinning hard drives in a compact flash form factor...was pretty amazing for it's time!

[@johnnisshansen]

Very intertaining, I remember harddrives 50x50x75 cm with whole 5 MB in 1973.

[@braddofner]

This was fascinating! I never knew how small those things got! You should have mentioned how LARGE the FIRST hard drive was! Look up the IBM Model 350.

[@SchioAlves]

I didn't even know there was a smaller than 1.8" HDD 😮

[@rhaib]

Same

They are short-lived oddities used in iPods and bake in the day when flash memory was cost prohibitive to get the desired capacity for handheld portable devices and when multi-gigabyte thumb drives were way too expensive for the average consumer.

3:30 I've dismantled several old hard drives over the years and frequently came across a hidden screw. Why on earth do the manufacturers hide them! As if it's supposed to deter casual opening of the drive?

[@JanusCycle]

I believe it's to detect casual opening for warranty voiding purposes. You wouldn't believe how many average non tech people have brought me hard drives to recover data from that they have already opened themselves. Here is one example, I immediately noticed the hidden screw had been opened already. kzbin.info/www/bejne/mmmloKywpqljhtU

[@SuperLittleTyke]

@@JanusCycle If non tech people think they can repair a hard drive, they are plainly stupid. Does a non tech driver attempt to repair his brakes without knowing what he's doing?

[@bland9876]

The smallest hard drive i have is an ssd that uses the wifi card connector instead of any or the M.2 connectors. It is wider than an M.2 but much shorter. If i had to guess it would be an M.1 drive cuz I've never heard that term used before and i doubt they would start counting at 2. The model is MZ-MPA0240/0L1 and is is 24GB in capacity.

[@Killbartman]

The smaller I see a hard drive the more I want one. I never known that harddrives can go as small as a SD card.

[@manoharmanu1460]

Wow never new we had spinning drives so small

[@brasilianguy5437]

This is evolution. Amazing. In this video I only miss the 5 1/4 hard disks as ST238R as consumer disks too. Bigger than that, only the mainframe HDs like the one seen on EEVblog #395

[@rootbrian4815]

*HDD. Mac users often get high-definition confused with hard disk drive.

[@brasilianguy5437]

@@rootbrian4815 but I'm not Mac usr, and I shorten oftn. For the context, HD fits well, no need to say "drive"...

I find mechanical disks to be reliable the new fNVME drives have weaknesses but will become more reliable as time goes I find mechanical drives often warn you in some way they are dying so you have a chance to back up important data I bought two mechanical 2.5in laptop drives one is 500GB the other is 1TB the 500GB is CMR tech and i am using it on this computer as I type I also have the 1TB drive which is SMR tech and am going to test soon with various OS's and see how well it performs with diffferent filesystems etc great video mate cheers

3:58 - you see the white tab? Lift it, easily insert the flat cable, and lower the tab back.

[@somename842]

apple and samsung work together all the time, so it’s not uncommon at all to see both brands on a part

[@fal3881]

thanks to the algorithm i've seen something that i probally never seen one in my life

[@HelloKittyFanMan.]

"You gotta use a lot of force to get this zero-insertion-force connector in." Nope. If you have to use any noticeable amount of force then either that's not a ZIF socket or you're doing it wrong. ZIF sockets have a locking lever that you snap down after plugging the cable (in this case, or chip, such as a CPU, in other cases) in and that's what keeps the cable tight.

[@JanusCycle]

This one is not so zero :)

[@HelloKittyFanMan.]

@@JanusCycle: Right, so it's not a ZIF socket like you called it. Unless it really does have a little sliding or swinging lock mechanism and you didn't notice it, and you were trying to plug the FFC into it while it was locked.
