THE SOLUTION FOR DATA
LTO-8 tape technology delivers high storage capacity, blazing fast transfer rates, easy-to-use functionality and steadfast reliability. Find key facts Here, and additional information below.
When it comes to long-term archiving, storage managers have to think about a lot of factors: equipment, media, maintenance, energy costs and floor space. Since costs for each can be significant, it’s crucial that data capacity is maximized at every opportunity while minimizing overheads.
ESG found that there is an impressive 577% return on investment when utilizing a tape solution for long-term data protection.* ESG also reported that LTO tape is thriving and has a bright future in organizations of all sizes. Their overall conclusion was that the more data that can be preserved on tape, the lower the overall total cost of ownership (TCO).
Now you can use the money that you would be pouring into another storage solution, where your business needs it most.

That’s a big advantage when you compare LTO tape with other technologies. SSD typically provides less than 2 TB of native capacity. That’s expensive when you consider cost per gigabyte. Hard disk drives today can offer up to 8 TB of native low cost storage, but it’s still more expensive when you consider cost and the need to raid your systems for data protection purposes.
Increasingly, data is compromised by more nefarious methods. Viruses can corrupt a file, hackers can steal trade secrets or an employee can sabotage a company’s most critical data.
In fact, three out of every four businesses have experienced a data disaster of major business disruptions that exposed them to potential damages. Almost daily we hear of data being compromised that can have serious negative consequences for those entrusted to protect that data.
One bank lost their backup tapes with sensitive data from more than 12 million customers. A software error corrupted records on both the primary and replicated disk for a major email provider. A virus infected a university computer, exposing the personal information of students.
That’s where LTO tape can save the day. Tape provides offline protection, isolating the data from software bugs that can occur during continuous disk-to-disk backup.
Ransomware. LTO technology is the only solution that offers a true “air gap”. Having a backup completely offline protects your data from both viruses as well as ransomware threats.
Encryption. LTO technology offers hardware-based data encryption (LTO-4 drives and newer), which provides powerful tape-level algorithm that doesn’t affect compression, performance and capacity.
WORM. LTO technology also provides for a write-once, read many option (LTO-3 tapes and newer) that stores data in a non-rewritable format. This further protects data from being errantly overwritten and also helps to address compliance regulations.
Don’t let your most important data go unprotected. LTO technology provides some of the best options available to ensure that your data is there when you need it.
Most importantly, the LTO format ensures that your investment today will continue to pay off for years to come. LTO specifications provide backwards compatibility to read/write with previous generations. LTO drive generation 1-7 are able to read tapes from two generations prior and are able to write to tapes from the prior generation. LTO-8 drives can read and write to LTO-7 drives. With a published roadmap, LTO technology allows you to better forecast how to address your future technology as you address your needs today.
And with the Linear Tape File System (LTFS), LTO tape options are more compatible than ever before. There’s no need for a proprietary system to locate that document or video file that you’re searching for. LTFS makes it easy and simple. It’s open source and open standard, meaning that it’s broadly available regardless of which brand of LTO tape that you’re using.
Today, LTO technology provides the confidence that the file you save can be accessed by a broad range of partners for years to come. That’s the LTO difference.
Tape? Yes, despite the common misperception that backing up to tape is slower than disk, tape delivers some of the best performance possible when comparing raw speed. In fact, it’s faster than disk.
Tape technology doesn’t have the same complicated backup constraints that slow down transfer rates on disk. With tape, transfer is far more straightforward and simple.
And with LTO-8 tape technology, you can enjoy read/write speeds that approach 750 MB/sec compressed. When you compare native data rates, that’s 360 MB/sec, which is faster than the typical 7,200 RPM hard drive (160 MB/sec).
So next time you’re considering performance as a key aspect of your decision, know that tape provides a great option that can outperform other storage technologies available on the market.

Luckily, LTO tape provides a reliable, offline protection against on-line data corruption. Compared to the shelf-life of disk (3-5 years), LTO tape can withstand the test of time, providing users with a shelf-life of up to 30 years. The protection is also there when you need it, offering a strong error protection and correction algorithm, with an error rate of 1 bit in 1x10E19 bits. That’s four orders of magnitude better than disk, whose error rate is 1 bit per 100 Petabytes. Once your data is written to the tape there’s no need to worry about whether it’s there, it’s immediately verified by the LTO “Read after Write” technology.
LTO technology gives you the confidence you need in knowing that your data is there when you need it. As a tape cartridge is kept offline, it’s a great solution for long-term archiving or for data that doesn’t need to be accessed immediately (cold storage). By diversifying your storage practice (disk-to-disk-to-tape being the best), you can ensure that the tape will always be there when you need. Even when disaster strikes. Now that’s something you can rely on.
Beyond archiving and backup, there are many other applications where data needs to be transferred from where it has been generated to another point. For example, in media and entertainment, the data might be video files that are being sent from production to editing, or for large data centers, it might be gigabytes of data that needs to be mirrored in a different location.
Traditional disk vs. LTO Technology: What options are available to me?
Traditional disk is far less durable, particularly when sending to and from remote locations. Solid-state drives (SSDs) are expensive – up to 90 cents per gigabyte. And Internet transfer drains resources, exposes your files to security concerns and can take a long time..
But fear not, LTO technology can help. In fact, for transferring gigabytes of data from one point to another — quickly, reliably and in the most cost-effective way — it’s your best bet. Best of all, with the capabilities of the Linear Tape File System (LTFS) and its open format, the tapes you need to send or receive are compatible between multiple vendors. Finding files is as easy as if you were plugging a USB drive into your computer, and the technology works across all platforms and operating systems.
Not to mention, LTO-8 tape is cost effective and much less expensive than disk and SSD. Cartridges are more durable, with heavy-duty construction, so are much less fragile than disk. They’re also more secure, with hardware-based encryption options and Write-Once, Read-Many (WORM) options to help further protect data. And with the threat of ransomware and cyberattack on the rise, tape is a reliable offline medium to store sensitive data with complete air gap protection,, so your data is less susceptible to virus, hackers, system errors or other threats.
For portability, think of LTO-8 technology as “low-cost high bandwidth in a box.” It’s easy to use, completely removable and easily transportable. With transfer rates approaching 750 MB/sec compressed and 360 MB/sec native, overnight shipping of 30 TB of compressed data per cartridge can be much less expensive (and faster) than sending via other methods. Transferring an entire data center is as simple as packing up a box full of LTO tapes and shipping them wherever they need to go.
With this in mind many organizations are moving rarely accessed data to tape technology, in order to significantly reduce the amount of data-storage carbon emissions without sacrificing the integrity of its stored information.
Additionally, energy costs money, and the cost per terabyte of tape storage is considerably less than all other types of digital storage, making the shift to tape appealing to both save substantial carbon emissions and save substantial money. In analyzing the total cost of ownership of digital storage, tape is also the most cost effective way to archive data, beating both cloud and disk in cost per terabyte per month.
As companies seek to achieve carbon emissions reduction targets, many are undertaking expensive adjustments within their supply chains. Data storage, a part of every organization’s strategic infrastructure, may provide an easy path that will contribute to emission reduction initiatives – while saving money at the same time!

LTFS uses the partitioning feature that’s available on LTO generations 5, 6, 7 and 8. With the use of partitioning, tape is divided “lengthwise” into two sections, or partitions. The smaller partition holds the index, which includes the file system information and metadata that provides details about the files contained in the second partition. When the tape is inserted, the index is quickly copied from the first partition to the workstation or server memory to deliver simple, fast access to the files that you need.
Benefits: With self-describing tape, complexity in data management is reduced. It allows you to view contents of the tape in the OS browser directory tree. And since it’s open source software and not proprietary, it’s easily sharable and increases data portability.
Beyond simplified backup and archiving with direct access to files from your desktop, LTFS gives tape new capabilities where alternative technologies had once been your only choice. You can share content between users working in different environments, allowing for remote data exchange. LTFS simplifies data interchange across workflows, providing for unified organization-wide file sharing. It’s independent of any hardware or software platforms, which means that recovery from disaster is faster and simpler than ever before. And for digital archiving and asset retention, it’s the leading choice with easier to identify and access files after years of storage.
LTFS opens the door to many new uses for tape. Video producers are turning to tape for simple and cost-effective archiving and workflow of high-definition digital content. Large and less frequently accessed files required for big data analysis and medical imaging are more cost-effectively archived on tape over a longer period of time. Any industry where vast amounts of data are being collected and stored – digital surveillance, oil/exploration, cold storage for cloud service providers and banking for example – can benefit from LTO tape with LTFS.
