The LTO ultrium specification first came into origin in the year 2000. The research findings of IDC are that LTO taper format has almost 82 percent share in the mid-range market. There are number vendors that are manufacturing LTO cartridges including TDK, Dell, Sony, Imation, Maxell, Verbatim and Fujifilm. AES-256 encryption has been added to the LTO 4 tape format’s specification. The performance of LTO4 tape also has been improved.

The LTO-3 tape drive operates at fast speed of 80MB/sec which has been enhanced up to 120 MB/s in the LTO4 tape drives. LTO4 tape cartridge can store double the amount of data which can be recorded in a LTO3 ultrium cartridge. LTO4 tape format has the capability to support compressed capacity of 800 gigabytes. This means that data equal to 300 DVD movies can be stored on LTO-4 tape cartridge. If you want to make further comparison, the collections of Library of Congress can be recorded on six data cartridges of LTO4. LTO 4 tape is the smartest and most economical choice as it also supports the advantageous feature of write-once read-many. WORM capability has been employed in both the third and fourth generation ultrium tapes. Hardware based encryption has been included in the HP LTO-4 1840 tape drive that increases the security level.

The 1840 LTO4 Tape drive by Hewlett-Packard is very powerful and robust that is capable of recording data of 1.6 terabytes per LTO4 tape cartridge. Hardware based encryption has been included in the HP LTO-4 tape drive that increases the security level along with unparalleled durability and efficiency which is the demand of the enterprise customers. 1840 tape drive is the first tape drive by HP that has the technology to store 1.6 TB data per cartridge in compressed mode. Powerful architecture and design of HP 1840 ultrium drive ensures unprecedented performance and robustness. Encryption technology is an added feature of LTO4 tape drive which lessens the worries of data managers and companies in case of data loss or theft. Because the encrypted data will be of no use to any one, in this way the companies can protect themselves from heavy and unbearable losses.

The organizations can secure their sensitive & precious information through the AES 256-bit encryption of LTO4 tape version. Unauthorized access and misuse of user information are prevented by the HP 1840 drive. The encryption technique assures easy-to-enable protection and security of information. The HP LTO-4 tape’s encryption technique compresses the data efficiently and maximizes the capacity. The data is encrypted in a cost efficient manner without effecting the LTO4 1840 tape drive’s performance and accuracy. 240 MB/sec is the transfer speed offered by HP LTO4 tape drive. HP has included another unique feature in the LTO 4 tape drive called the “data rate matching”. This is a unique mechanism that delivers fastest tape performance as it adjusts the drive’s speed according to the transfer rate of host thus ensuring continuous streaming of tape drive. The output level and performance of Hewlett-Packard 1840 tape drive is unparalleled. It is very user friendly and is also backward compatible. So the companies are more confident as their investment is safe and protected by the backward compatibility of LTO 4 ultrium storage format.
