USB Memory Stick
The use of USB drives and the best of devices based on other flash memory is simply copy-to and copied from. By that I mean to copy the information to the offers to host it, copy it from the portable hard drive into a local hard disk to use it, and then copy it back to USB drives to store store it.
Never run disk-intensive applications directly against files stored on a USB drive.
If you copy to and from even ten times a day, you’re looking at three years using the low end of the lifespan of flash memory. (Yes, I know that is not exactly In fact, it’s way more complicated than it ;. factoring in such things as the type of file system FAT or NTFS, the effectiveness of the device drivers , and even the circuits on the device-specific flash memory – but that is an order of magnitude).
You can also note that your application speed when you copy your database to your hard drive to use. While reading the flash memory is usually quite fast, not text.
And finally, if you really need external storage, a possible advantage is simply wrong solution for your problem. There are many external hard drives that can do the same job without the restrictions stated. Or perhaps a networked solution is the way to go.
Knowing that the device based on flash memory will wear out cheaper in the end, there is one other thing that you need to be sure to do, and that is for backup.
If only you keep copies of important data on the flash drive you’re asking for trouble. It will wear out eventually, and your data will be completely unrecoverable.
Remember the “golden rule” of the backup:
If only one copy, it is not backed up.
If only one copy on a flash drive, its days are numbered.
Insert the flash in flash memory
Flash memory chip known as “flash” because to write to it, the memory is loaded, and then a signal is sent to the memory circuits that says “remember this” – like the flash on camera. (In all honesty, I do not know if modern flash memory using exactly this technique, but it remains a fairly accurate metaphor for this process.)
Once the memory is “projection”, energy can be eliminated completely, and the memory will retain whatever has been written for it.
The problem is that the memory can be shown only in this way many times. I’m looking for the numbers from 10,000 to 100,000 times – whether it’s with anything, I’m sure growing over time as well. Regardless, there is a limit. When that limit is approaching, a number of memory components can not properly remember what has been written for it, leading to corruption. It can only get a single bit of information is wrong, or to “wear out”, the entire contents of a flash memory chip to be lost.
A number of flash memory chips, perhaps even most, now also includes circuitry to avoid “bad bits”. That means that if a portion of the flash memory eventually wear out and deteriorate, the chip itself can be offset, and it will look to the user like everything is fine. Another method is called “wear leveling.” This spread usage across the entire flash memory device, even if you only have text for the same seat in the same file every single time.
But these techniques only lasted so long and only delay the inevitable.
Now, in your case, you’re using a USB thumbdrive in perhaps the worst possible way for life. the database application in particular are notorious for writing to disk – a lot – such as tables, fields, indexes and the like are being updated. Even if you do not write to your database, the file can be updated with things like “last access” information and other administrative fine. As a result, the USB drive has been written to. Great number of.
With all that is written, scores failure of some random bits or bits of flash memory seems not far-fetched. Remember that, in case of bad luck, it just may take a little trail of information to make the entire contents unreadable.
What about SSDs?
SSD or Solid State drives are actually based on flash memory. And yes, they will wear out too.
Just not as quickly.
There is a difference between memory “cheap” flash I’ve discussed so far, and flash memory on the SSD. USB connectivity; CF, SD and microSD memory cards are all relatively cheap. The types of flash technology they use is, as I have described, prone to wear out if recorded in the “too much”. inexpensive drives can wear out from use frequently in a relatively short time period.
Not entirely so for SSDs.
SSD flash technology to use a more expensive, and are designed differently than their brothers their inexpensive. Even when the price goes down to reach the cost per gigabyte of mobile hard drives, this technology is still fundamentally different and often significantly larger physically.
The same problem applies: an SSD will wear out – it just takes a lot of time to do so. In fact, it is not unreasonable to assume that an SSD used as the main drive of a computer that can outlast the useful life of the machine itself; again, depending on how it is used. It will wear out eventually, but you will likely have moved to another before that time.
Regardless, it is important to remember that the media can and will fail. The difference we’re talking about what to do with how fast, on average, the failure will occur. Again, based on the use of traditional spinning hard drives and SSDs will significantly outlast the cheaper flash drives.
And you need to back them up.
