Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Capacity : the capacity printed on the product photographed illustrates the range; the one sold is that of the title and the specifications.
  • Format and interface : 2.5 or 3.5 inch, SATA, NVMe M.2, with or without a heatsink: the photo is not enough to tell.
  • Drives not supplied : external enclosures, docking stations and NAS servers ship without a drive, unless explicitly stated.
  • Accessories : cables, adapters, caddies and screws are supplied only if the specifications say so.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

The slightest doubt about a specification? Contact us before ordering and we will check for you.

1 year manufacturer's warranty

This product is covered for 1 year by a manufacturer's warranty (the brand's official warranty). Your iris.ma invoice serves as the warranty document: keep it safe.

A problem with your product? Don't worry: contact us by phone, WhatsApp or e-mail. Depending on the brand, we direct you either straight to the repairer appointed by the brand to fix your product, or to us — and we take care of the rest.

  • If a repair is possible, it is carried out free of charge.

The warranty covers breakdowns occurring under normal use, as defined by the brand's terms. Product breakage (drop, impact, liquid…) is not covered, nor are certain consumable parts.

Frequently asked questions about this product

Can the Synology HAT5300 20 TB drive run around the clock?
Yes, it is designed to run 24 hours a day, 7 days a week, with a rated workload of 550 TB per year. That is the fundamental difference from a desktop drive, which is built for a few hours of activity a day.
What transfer rates can you expect from the Synology HAT5300 20 TB?
Up to 281 MB/s sustained, with a rotational speed of 7,200 rpm and 512 MB of cache. The sustained rate describes what the drive can maintain over time, not a peak measured over a few seconds.
What interface does the Synology HAT5300 20 TB connect to?
SATA 6 Gb/s, in a 3.5-inch form factor — the standard connection for NAS and server drive bays. Its capacity is 20 TB.
What does the MTBF quoted for this drive mean?
The mean time between failures — here 2.5 million hours. It is not the lifespan of a single drive, but a statistical probability established across a population of drives: it is what an operator uses to size a stock of spares.
What happens in the event of a power cut?
The drive has a persistent write cache: data waiting to be written is not lost when the power goes. This is what limits data corruption during a sudden outage, even before a UPS kicks in.
How long does it take to rebuild a RAID array?
Rebuilds are rated up to 27% faster on a Synology NAS than with a third-party drive. This is the most critical window for a storage array: while the array is degraded, a second failure becomes fatal.
How do you update this drive's firmware?
From DSM, in one click, without removing the drive from its bay. It is a real operational gain: with a third-party drive, a firmware update often means taking it out and connecting it to a dedicated computer.
Is the Synology HAT5300 20 TB drive new and under warranty?
New, reference HAT5310-20T, in the 3.5-inch form factor, in original Synology packaging. The invoice serves as the warranty document for 1 year. Keep it: it is the document requested if you make a claim.
