Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

Problem with an order right now? Write to [email protected], [email protected] or [email protected] — answered the same business day. The letter also lists our group and store owners' contacts.

The Seagate Exos X18 (ST18000NM000J) is an 18 TB enterprise-class 3.5" SATA III (6 Gb/s) hard drive designed for hyperscale cloud and large-scale data centre storage. Operating at 7200 RPM with CMR recording and enhanced caching, this helium-sealed drive delivers high capacity, reliable performance and optimized power efficiency for dense rack deployments.

Advantages

Seagate Exos X18 provides the highest-capacity 18 TB option for more petabytes per rack, combined with enhanced caching and low-latency tuning for hyperscale data transfers. The PowerBalance™ functionality optimises watts per terabyte, while the helium-sealed design and proven side-sealing weld technology reduce weight and improve handling robustness and leak protection. Built-in digital environmental sensors monitor internal conditions for stable operation, and Seagate Secure™ features enable secure, manageable drive retirement.

Suitable for

  • Hyperscale cloud storage and massive scale-out data centres
  • Enterprise servers and high-density rack arrays
  • Business-centric NAS systems and archival storage

Key specifications

  • Capacity: 18 TB (18000 GB)
  • Form factor: 3.5"
  • Interface: SATA III (6 Gb/s)
  • Spindle speed: 7200 RPM
  • Maximum sustained transfer rate: up to 270 MB/s
  • Technology: CMR (Conventional Magnetic Recording)
  • Helium-sealed design with side-sealing weld
  • MTBF: 2,500,000 hours
  • Manufacturer model: ST18000NM000J
  • EAN: 8719706020442

How to use

Install the Seagate Exos X18 into a compatible 3.5" drive bay or storage chassis with SATA III support. Use appropriate mounting screws and connect power and SATA data cables to the host controller. For best performance, configure the drive in systems that support enterprise-class workloads and ensure firmware and drivers are up to date. When deploying multiple drives, follow your server or array vendor guidelines for RAID, cooling and airflow.

Recommendations

Operate the drive within the manufacturer’s specified temperature and humidity ranges, provide adequate chassis airflow for helium-sealed drives, and follow standard enterprise backup and retirement procedures. Use Seagate Secure™ features when decommissioning drives to ensure data is rendered inaccessible.

“It is pretty safe to say that 2020 was indeed an odd and stressful year fill with so many unprecedented issues we doubt anyone could fault a company for pumping the breaks and waiting out the storm that is/was 2020.”
