A couple of weeks ago, I decided to test if the allocation unit size (when formatting a disk) has any effect on the speed at which data is transferred to the disk. Note: This was on a conventional hard drive. I have not tested SSDs.
Without boring you with the test procedure, I found that:
1) Increasing the allocation unit size from the Windows default of 4096 bytes, to a higher value, like 16,384 bytes has very little effect when writing large numbers of smaller files. In fact the average amount of wasted space on the disk is around 8,192 bytes per file, whereas the average wasted space with an allocation unit of 4096 is only 2,048 bytes per file. However, there is less fragmentation of the disk with larger allocation units.
2) The larger allocation unit has a major effect on performance when transferring large files (several Gigabytes). With very large files, like system drive images (30 Gigabytes and more) the write speed to the disk increased between 30 and 40%
Conclusion: If you can dedicate a complete drive or partition to large files, like video or image files, it may be worthwhile to format that drive with a large allocation unit, like 8,192 or 16,384 bytes. Since the disk will not hold large numbers of files, the increase in wasted space per file is not important.
Note: Certain types of encryption will only work on disks with 4096 allocation units. I also suspect that increasing the allocation units on SSDs will have little or no effect, but I have not done tests on SSDs
For my tests I used a 4TB Western Digital disk drive in an old Vanteq Nexar enclosure, connected to the computer via USB3. It will probably not work in the newer line of Vanteq enclosures, as their transfer rate seems significantly slower than the old Nexars

Yep. And in the old days (pre-IDE era) when disks reported the real number of platters and heads they contained I would spend ages fiddling with the interleave to get the best setting for a particular processor / MB / HDD combination. You could double throughput by getting it right, so it was seriously worth it.
Ah, disks span slower in them days, I remember it well...

Yep, that's true, size matters. The bigger the unit the larger amount of data that can be stored without fragmentation or risk of losing correct order. I'm kinda keen on 96 columns[^] per unit

I was an 80 column by 12 rows man.
And we measured our code by the "Inches thick" or "pounds weight" scale, not this namby-pamby "lines" metric they insist on today!

Which goes to prove size does matter.

imho, this would definitely be a good/great tip-trick.
thanks, Bill

Thanks for the upvote. I will prepare it as a tip/trick and post it.

Hi,
I recently a joined a client, I developed beautiful concepts of my own, when I try to send some of that to use in my office to make a better product, my client doesn't allow it.
Just asking is there anyway other than Emails to be able to upload some files and download it in the office network and which is not harmful and blocked usually so that I can reuse my concepts and not follow clients standards both.
Thanks,
Abdul Aleem

Memory?
Pen and paper?
Seriously, if your client doesn't allow you to reuse code you've developed externally, then don't do it. Any "solution" we give you will only end up with you getting into trouble for circumventing their standards. Unless you can convince them to allow it, you're going to have to reinvent your concepts.

The company does not allow you to receive e-mails from your personal e-mail.
They have security in place to prevent that which, in this day and age, is probably prudent on their part.
I would suspect they will not allow you to bring it in on a USB device either, and they shouldn't. That is a method of infecting networks.
So.. if you think you have a product they can use - ask THEM, not US, how to get the product in.

As Tim says, if they have locked you down to the level of preventing emails, they've probably locked you down for everything else as well. You will need to talk to them to find out if there is a "permitted way" to do it.
But...be aware that they may want (or claim) the rights to the software if it's going to be used in one of their products. And if you don't provide it, they may very well refuse to let you import it, as it leaves their products vulnerable if you leave the company for any reason. Many companies have a "developed or created while in our employ" clause in the employment contract for that very reason. Which means you may not be able to use it elsewhere after this.
Think carefully before you do this.

Yeah I know that crap in most of the cases it won't be an issue, at least from my side I wouldn't claim for that, but yeah probably in some cases people did, OK I would try to reinvent it, its time taking, I did develop very beautiful methodologies when I was preparing for the interviews.
Thanks,

Open a Dropbox account and upload the files to your allotted space. At home or your office, download them. I suspect you can use Google for that, too.

Why not sit down with the client, explain what you are doing and how it adds value to the company. Ask their help in finding you a safe way to bring your material into the network. Perhaps they could provide you with a write only USB stick that they could scan before allowing you to use it ?
cheers, Bill

If a company has gone to this extent to protect its network then you will need to be very careful. Any attempt to get round it will probably be banned in company policies and any hence any act to contravene that can be seen as a disciplinary matter. (Ie no job)

Show your supervisor a demo of your code on your personal laptop, ask if they're interested, and if so, how to get it to where it needs to be.
Possibly, they'll have you write it to a CD or similar and hand it to a properly-authorized admin to put somewhere accessible.

Set up another external email address? I cannot believe that they will have restricted email so far as to only allow emails in from a whitelist. What they probably have done is restrict what attachments they will allow on emails. Most will disallow .exe. ,.bat, .ps1 etc, and many will disallow compressed files such as .zip.
