USB Flash Drive and manually transfer critical data files to it as necessary

If you do not want to use SuperDuper!, you can clone your drive using USB Drive. However, I recommend SuperDuper! because Disk Utility Restore feature may result in a clone with permission errors. SuperDuper!, on the other hand, consistently produces perfect clones. You can also use a donationware program called Carbon Copy Cloner, which is very similar to SuperDuper! Backing Up Specific Files and Folders In addition to cloning your drive on a regular basis, you might want an easy way to back up specific files and folders, especially if you do not store valuable data files on your boot drive. Many Mac OS X applications, such as word processors, spreadsheets and databases, include a special option for automatically creating a backup of your work every time you save it. If you use this feature, select a backup location on a second drive so your most important data will always be saved on two separate drives. Another way to back up critical data is to use a program like Apple Backup, available for free for MobileMe users.
You can schedule Backup to automatically save data files to your iDisk so you will know that you always have an offline backup of the data. The full version of SuperDuper! and Carbon Copy Cloner also let you save selected files and folders to an external drive on a scheduled basis. Another easy option is to purchase a USB Flash Drive and manually transfer critical data files to it as necessary. Backing Up to CDs and DVDs Some applications, like iTunes and iPhoto, have built-in features that let you back up your valuable data to CDs or DVDs. This is the perfect solution for data files that are very large, such as a photo or music collection. Large folders of data can also be easily backed up to CDs or DVDs using the Mac OS X 10.5 Finder Burn feature. Simply insert a blank CD or DVD into your computer optical drive, move files and folders onto it and click the Burn button on the Finder window or move the disk to the trash to create a permanent copy of your data. You can also use a free application, such as Burn, to create backup CDs and DVDs of your data. With so many easy-to-use options for cloning your system and backing up your valuable data, there is no excuse for any Mac user to lose data and precious time trying to recreate or restore original files.
And, if you use Mac OS X 10.5 Leopard, you have the additional advantage of Time Machine. So, to sum up. The average reading speed of USB Flash Disk is approximately 150 Mb / s, while recording - 120 MB / sec. Average access time of less than 0.5 ms, which indirectly indicates the use of fairly good memory chip MLC-NAND, and enough "smart" controller. Of course, to the SSD-top devices with SATA drives him away, but the advantages over conventional external hard drives are obvious. However, in this barrel of honey wormed and fly in the ointment. Drive Apogee Astro Drive A101 64GB gets very hot during operation. Already after ten minutes of active use housing drive almost burn your hands. On the other hand, what else to expect from the aluminum case with almost complete absence of any ventilation. Interestingly, and how much heat the older model of 128 GB?The hard drive is suited perfectly for both home and office use and the public acceptance level is very high for them. All this popularity has also had a negative effect on the hard disk. Since we usually take the hard disk for granted, we often fail to back up data on them, protect them properly and handle them with adequate care, causing data loss situations that only create panic because there is a general lack of knowledge on hard disks.
