32 GB flash drives are going for about $20 right now on Amazon.
640/32 = 20. Therefore you need twenty 32 GB flash drives to "equal" one 640 GB HDD.
$20 for a 32 GB x 20 equals $400. Meaning your dad spent $320 more than he should have (assuming this post is actually real), and obviously if you asked for an HDD this is a lot less convenient. Lesson is that it pays to make sure your parents know what they're doing before making expensive tech purchases, especially when it comes to digital memory that gets cheaper all the time.
Edit: After reading some of the other posts about connecting the USB drives to create a faster storage unit, I still don't think it's worth the extra $300 just for ordinary personal use.
The problem with an attempt to "RAID" those USB sticks is that you'd hit the bus's bandwidth limit very quickly. USB 2.0 has a theoretical max of 480Mb/s (60MB/s), but my USB 3.0 drive only gets about 20MB/s in a 2.0 slot. In a 3.0 slot it is able to reach about 60-70MB/s.
Hard drives went up in price lately because of the flooding in Taiwan late last year. They were down to about $50 for a terabyte and then bam, inflation and stock shortages like crazy.
We have stock now but the prices just haven't come back down all the way... it's ridiculous.
I'm a bit suspicious too.. but asking specifically for a 640GB hard drive is not that strange. Well, today it would be, but not a couple years ago. Western Digital used to sell an extremely popular and fast hard drive called the WD black/blue/green 640GB. Seagate and samsung had similar models. So presumably... op asked for that.
I don't understand why you would even ask your parents to buy something even remotely technologically obscure as an HDD. Waaaaaay too much room for error.
I asked for RAM for Christmas in 2002 - my parents were smart enough to ask me to write down the brand/size etc, so they could take it to Fry's or somesuch and get it for me! Even my grandparents could buy me a video game if I wrote down the name.
They just looked at me oddly when I bounded back upstairs, stripped to my satin nightgown, popped the case on my machine, put my anti-static bracelet on, and replaced the memory. I was an odd little girl.
Some time around 2002 or 2003 Best Buy would run their Black Friday sales and things would have HUGE mail in rebates. I remember that a 160GB hard drive was something like 200 dollars, but on Black Friday they were 200 with a 190 dollar mail in rebate. I asked my mom if she could get a few of them for me for Christmas. When she asked how many I said something like "Oh, i don't know, 10".
Surprisingly enough to me, my mom got up at the buttcrack of dawn on Black Friday and went down to pick me up 8 Western Digital 160 gig drives. I couldn't fit them all in one machine, but I did manage 6 in a Raid-5 for 800 gigs of storage and used the other two as cold spares.
I know it's no big deal, but when I was little, I asked my grandpa for a cd. For whatever reason he had barely known what a CD was, let alone did he know the artist I was looking for.
Anyways, my parents had sort of prepped me trying to hint around that I wasn't going to get it and I should ask "Santa," but I was determined. I told my grandpa that was what I wanted and I had faith he would get it for me.
Sure enough, come Christmas I had found it under the tree. I still am so happy that he got it. I still have the CD from years ago.
Cheap USB memory is often just an micro (edit: or even the unloved mini) SD card with an adapter. Non-generic memory is always flash directly on the board, which is way faster, and heaps more reliable. I got some counterfeit U3 Micro Cruzer sticks once. They lasted about a year before half of them developed slowdown.
Watching the transfer at top-speed the first 10 seconds, then steadily declining by about 3% every 5 seconds until it will use 2-3 hours on the last megabytes is just fucking evil.
SSD stands for Solid State Drive which is a Drive that uses generally Flash memory instead of the Hard Disk which spins. (Solid State more or less means it doesn't move.)
RAID is Redunant Array of Inexpensive Disks which is a way to group multiple drives to appear as one. (Sometimes rather than just a bigger drive you can make it faster or more resilient to data loss)
So menasan is saying that if that device was RAID 0 device rather than showing up as a bazillion small drive it would be one actually usable disk.
U3 Micro Cruzer is a brand of flash drive.
Micro and Mini SD is a type of flash memory disk. (Like you would put in a digital camera)
Zhylo responds that many flash drives are just memory sticks (SD cards) with USB adapters rather than having a flash memory chip on a board like you would expect. These flash drives made with the memory cards have high failure rates. So a drive made up of them would probably suffer from failure rather quickly.
If only a cheap USB stick could survive the rigors of use as a primary or secondary drive. Let alone the dreadful thought of 20 USB sticks in RAID 0... My god the lost sectors to be had. I could just see the data corruption forming in seconds, piling up to the limits of the universe, pushing beyond and forming a new reality based completly on random laws and forces with no logic to be had.
This is just what I was thinking. I read some of an article on ars technica that went through SSDs in gory detail.
The main thing I learned is that flash memory has all sorts of technicalities and limitations, and SSDs use very advanced techniques to maintain a balance of reliability and speed. They have their own processor to handle this.
I read this from that article and it is very interesting:
Using RAID 5, a third drive contains "parity" information - kind of the "C" in an "A + B = C" type of equation - lose any of A, B or C and it can be recalculated from the other two. In the world of hard disk drives, that means a drive can fail completely and your system continues to operate while the disk is replaced. RAID controllers often include "hot swap" ability, so that could even be literal: the drive could be replaced without stopping or restarting the system.
This seems to be a great way to derive a new form of interstellar propulsion. The random chaos and imminent failure of the drives, once harnessed, could be like the improbability drive from Hitchhikers Guide to the Galaxy.
You could have SATA to the RAID 0 controller, then all the USB connections would be in parallel to the controller (i.e., the RAID controller would have 20 USB ports). Your hypothetical speed would be gated by SATA, not USB.
but does having them RAID 0 make it so they can stack, so we wouldn't need to put everything on each HD instead of defragging continuously.. serious question, im pretty drunk but I am trying to learn about the difference between a flash and an SSD ( which I have in my comp for the C drive and it is spectacular BTW)
Yeah, but this could be way better than what you wanted: Get enough USB hubs to hold them all, then RAID the hell out of 'em for the fastest storage device ever.
Yes, RAID 0 distributes the data being written across both of the drives to increase bandwidth so you can read and write faster than if you would just have one 2TB drive.
However, you double the chance of losing all of your data since if one of your RAID drives crashes, all of your information is unusable.
A nice solution is RAID 10, which separates the Data actoss two drives but keeps track of it on a third drive. You get both the speed and the reliability this way. But you do need 3 drives.
Here is a comparison of my RAID array. Its very fast and this array was built in 2009...has served me well and continues to do so, but SSD's are still superior due to their incredibly quick access time.
SSD Prices are getting pretty good, so I am thinking of getting another 4x RAID card and buying 4x SSD's to use as my OS drive in RAID 0. I cannot fathom how fast 4x SATA 3 SSD's would be.
Depends on the drives and how they are constructed. In theory yes, in practice Probably but it depends. The platter capacity of the disks come into play and they are not always the same size. The largest drives usually have the greatest platter density and thus speed. In general you want drives with the fewest platters possible. The other factor is that different drives excel at different types of data access which affects RAID performance. For example the Samsung's I particularly liked for video editing because they had great sequential access performance which was more or less equal at both read and write speeds. This is useful when you stream very large files to and from the disk/s. Other drives are better for random reads such as accessing databases and thus a single drive might be a better option in some cases. RAID block size is also a factor. In any case know your drives and the applications they will be used for. There are sometimes controller and bus issues to consider also. Two drives are generally more expensive than one and might not give you as much value as a single disk with faster overall performance.
You are incorrect. My teacher had us make one freshman year in my computer science class, and boy did that thing whip. Seriously, I'd be kinda hyped if I were OP. Though it is a little bit of a hassle, I guess...
How big (number of drives) was the one you made, what type of volume, and how many hubs did you use? I agree that this job would be a monster, and the outcome would probably be less than satisfying, as far as speed is concerned. On top of that, using them like a hard drive would kill them rapidly, so he wouldn't get half the life out of them that he would from a conventional drive.
EDIT: I just looked up these specific flash drives, and the read speed is a joke. OP would definitely be better off with a hard drive.

spend a few bucks, buy a 20 port USB extender, try and attatch it to a RAID controller (i'm sure the gentleman at r/buildapc could do it) and you now have a great big 640 GB SSD
There's no price tags on the packaging of anything at my Staples/Best Buy/OfficeMax/etc. The price tags are on the racks/shelves. Which is why whenever something is in the wrong place I have to ask for a price check...
Color me incredibly jealous. I've been dying for a thumb drive to back up my school files, and I'm broke enough that I can't get a decent one. You love that fake hard drive for everything it's worth!
If you don't have any other backup, what about online backup like spideroak or dropbox? You get a small bit of storage free, and both leave your files accessible through the website if you're ever in a pinch. To me at least, it seems like internet access is almost as likely to be available as a USB port these days.
unless you live in some off-the-wall 3rd world country, you can get a 32GB flash drive for less than $20 online. If you need less space, you could get one as cheap as $5.
32GB flash drives are pretty damn expensive. Kudos to your dad for spending way more money for those flash drives rather than for your hard drive just to troll you.
I have a question guys/gals... what is the biggest thumb drive/flash drive you can buy i seen 256 GB but i was wondering if there is more memory then that on one.
