![]() DAT72 tapes, with a raw capacity of 36 GB run around $10 each, and 20 of these cartridges, with a total capacity of 720 GB, would cost around $200. LTO-4 cartridges, with 800 GB native (about 1.6 TB compressed) cost around $40 or more, which in this case, may actually cost less than comparable hard drives. In contrast, LTO-3 tape cartridges, capable of storing 400 GB native (800 GB compressed) cost at least $25, when bought in large quantities. Today, terabyte hard drives are available for less than $100, and 1.5 terabyte drives can cost as little as $150. ![]() Plus, the cost per megabyte of a tape cartridge and drive is often higher than the comparable hard drive backup. In other words, tape may be a hassle for some people because it is slower than disk backup. If the data is on another cartridge, you have to eject the cartridge (or, if it's in a library with more than one drive, you have to load it into the other drive), and have the drive search for the file. If you want to restore a file that is at the end of a tape, the drive must go through the entire tape to find the file you want. Tapes are not random access like hard drives. There are many reasons why SMBs may choose to use disk-to-disk backup instead of tape storage. In general, for long-term storage and successful recovery of data, tapes may be the best option. Serial ATA (SATA) is the new kid on the block, and drives as large as 2 TB in capacity are currently available, and it will probably be around for at least another decade. But SCSI has been around for more than two decades, and Fibre Channel (FC) has been in use for more than a decade, and they may continue to be around for a while longer. Parallel ATA (also known as IDE) drives are also well on their way to becoming dinosaurs. The original, tiny capacity drives of the early 1980s that used MFM or RLL interfaces probably can't be read today because it is probably extremely difficult to find an old PC or a drive interface card that could read it. Hard drive interfaces may not be as long-lived. And although many early tape formats are not well supported today, it is possible that tapes made today will be readable on future drives. Drives that can read nine-track tape from the 1980s are still available. ![]() For example, a tape written by a digital linear tape (DLT) drive, made nearly 20 years ago may be readable on recent DLT drives. In addition, many tape storage devices are backward compatible. Tape cartridges may last for as long as 30 years if they are properly stored. In this tip, read about the pros and cons of tape storage, popular tape data storage technologies today, and how tape compares to other backup considerations in terms of reliability, cost and more. Also, in the case of a disaster, tape recovery services can be used to clean and dry tapes, and recover much of the data that was originally stored on them. Tape cartridges may even survive floods and other disasters that would wipe out systems based on disk storage. And tape cartridges can usually recover from drops and other damages that could make hard drives non-functional. For example, backup tapes can be removed and stored safely offsite. The USB30 is an ideal storage and backup solution for power desktop and workstation users.There are many advantages to using tape backup and tape libraries. With its unique blend of high-capacity, high-performance, excellent reliability and affordable pricing, ADR delivers superior value for the demanding storage requirements of today's digital age.OnStream's ADR tape drives combine the capacity and low cost per gigabyte of a high-performance tape drive with the convenience of a floppy drive. This technological breakthrough delivers exceptional transfer rates and data reliability while maximizing media life and minimizing audible noise. ADR is based on revolutionary 8-channel array technology that allows the solid-state design to read and write eight tracks of data simultaneously. Advanced Digital Recording (ADR) is an all-new, variable speed, digital tape storage solution. ![]()
