Many people use the terms 'Tape Backup' and 'TB hard drive' interchangeably, but they're very different. While they both store digital data in an offline fashion, a 'TB hard drive,' also known as a Data Deduplication Storage Appliance (D2) and Thin Deduplication Array (TDA), is an appliance that uses flash memory instead of tape cartridges to provide dramatically improved data transfer rates. As a result, TB hard drives can store up to 30 times as much data on the same amount of physical disk space compared with tape backups.


Featuring low latency, high bandwidth, and ultra-high density, TB hard drives are the best option for companies dealing with massive amounts of data because they can help organizations reduce their storage costs by around 80 percent while reducing power consumption by up to 70 percent. And, due to their ability to quickly recover data in seconds or minutes rather than hours or days, TB hard drives have become very popular within financial institutions and healthcare organizations where fast recoveries and quick access to the most current data are critical.

How much data can 1 TB hold?


1 TB of data can hold more than 500,000 (500k) images (pics or .jpg files). It can also hold 500 hours of HD video. *These are estimates only.

How do I connect my computer to the TB hard drive?

The TB hard drive has multiple connectivity options ranging from USB 3.0 (external hard drives typically use USB 2.0), iSCSI, and Fibre Channel interfaces which allow you to connect it directly to your network switch using different cabling depending upon your infrastructure topology and budget requirements. Once connected, hosts access the device through a standard block storage interface such as SCSI or iSCSI where they can create volumes and provision LUNs for application servers requiring block storage.

What kinds of data can I put on a TB hard drive?


A TB hard drive is optimized for high-workload, active data where fast random I/O is required. This makes it ideal for active transaction logs, databases, scientific modeling, and VDI boot/decompression loads. It's also well suited for archiving long-term cold data that will be infrequently accessed but needs to be available online when needed. This would include media files such as video, music, and large CAD files.

TB hard drives are extremely reliable. They have no moving parts which mean they're not susceptible to the same physical failures as standard hard disk drives due to vibration or shock damage so they can be deployed almost anywhere. They also incorporate their power supplies so no external power is required.


Visualizing a Terabyte

1 TB (one terabyte) = 1024 GB (gigabytes). The number of songs it would take to fill a TB? 8.76 million! If that's not enough space, you could probably just buy a bigger TB hard drive!

Terabytes of Trivia

A hard drive with a capacity of one TB would hold the following:

  • Over 2.5 million MP3 songs (at 4 minutes per song, 320kbps bit rate)
  • Over 10 thousand hours of 1080p HD video (at an average clip length of 45 minutes)
  • Over 200 thousand hours of digital images (at an average file size of 1.4MB per photo)
  • Around 500,000 Word documents (based on the size of a one-page word document being around 3KB)
  • Around 400 thousand spreadsheets (based on the average size of a spreadsheet being 1.2MB)
  • About 100 thousand hours of digital video (at an average file size of 800MB)
  • Around 2.5 million PowerPoint presentations (based on an average presentation being 20MB)
  • About 10 million pages from your favorite website (based on the average page containing 100 words and 20 links, and an average link's size being around 16KB)
  • Around 2 million images (at 1.4MB per photo)

What is the TB hard drive's MTBF?

The TB's mean time between failures (MTBF) is around 856,000 hours which equates to roughly 114 years. So you can feel confident that your data will be safe for a long, long time.
