20TB enterprise SATA · Grade A refurbished · 12-month warranty
Seagate Exos X20, model ST20000NM007D. Helium-sealed, 7200 RPM, conventional magnetic recording. Not SMR, not a shucked external, not a desktop drive with an enterprise sticker on it.
Photos show one unit from this batch (serial ZVT58TL0). Your drive is the same model; its own serial and SMART report are emailed on delivery.
What you get with your drive
- Your drive's own SMART report, emailed on delivery, tied to the serial number on the unit we send you: health, performance, power-on hours, reallocated, pending and uncorrectable sectors, interface CRC errors, power cycles and temperature.
- The report on file, permanently. Ask us for it any time, before you order or two years later, and we will send it.
How every drive is checked
01 · Sourced Grade A. Every drive is refurbished, graded A and sanitised before it reaches us.
02 · Tested here, against its own serial. We run our own SMART capture on every drive before it is offered. We confirm the recording type from the drive's own model identifier, and we record the reading against the serial on the drive body.
We do not reset counters, ever.
03 · Your report comes with the drive. The reading for your specific unit is emailed to you when the drive is delivered, and kept on file permanently.
This batch, and why the hours read near zero
Two units. Both tested here at 100% health and 100% performance, with zero reallocated, pending and uncorrectable sectors and zero interface CRC errors.
These are ex-datacentre drives. Their SMART counters were cleared during refurbishment, before they reached us, so power-on hours read close to zero. That figure is not the drive's lifetime use, and we will not sell it to you as if it were. The unit photographed was manufactured in June 2023. We did not clear them. We report exactly what the drive shows today, and your report says so in writing.
Ships from Dubai
UAE delivery in 1 to 2 working days. No import, no customs charges, and if you ever need the warranty, the drive goes back across town, not across the world.
Data sanitisation
Drives are sanitised to NIST SP 800-88 Purge before they reach us. Purge is the level at which recovery is considered infeasible using state-of-the-art laboratory techniques, executed with the ATA Secure Erase or Sanitize command set. Those are firmware-level operations, so they reach areas a logical overwrite cannot: sectors that have been mapped out, the drive's overprovisioned space, and any host-protected or device-configuration overlay areas.
We do not perform the wipe ourselves and we do not issue a per-drive sanitisation certificate. If your compliance records need documented sanitisation evidence, ask us before ordering and we will tell you honestly what we can supply.
One honest limitation
SMART evidences a drive's present health and its workload history. It does not predict the moment a drive will fail. Anything you cannot afford to lose should be backed up whatever grade it carries.
Manufacturer specification
| Capacity | 20 TB |
| Model | ST20000NM007D |
| Part number | 3DJ103-881 |
| Interface | SATA 6 Gb/s |
| Spindle speed | 7200 RPM |
| Cache | 256 MB |
| Recording | CMR, not SMR |
| Enclosure | Helium-sealed |
| Rated MTBF | 2.5M hours |
| Form factor | 3.5 inch |
These are Seagate's figures for the model, not measurements of any one unit. MTBF is a population statistic and says nothing about an individual drive.
Packing
Anti-static bag inside a foam-lined box rated for drive shipping. Drives break in ways that do not show on the outside of a carton.
Check it yourself on arrival
We would rather you did. Run CrystalDiskInfo or Hard Disk Sentinel, and compare what it reports against the report we sent you for that serial. The figures should match. Power-on hours will read a little higher than the report, from our own testing and the time since.
If they don't, tell us immediately. That would be a serious failure on our part.
30-day returns, twelve-month warranty
You have 30 days from delivery to return the drive for a full refund, for any reason.
If a drive fails within 12 months of delivery, you choose: replacement or refund. No restocking fee, and you do not need the original packaging.
What the warranty does not cover: your data. A hardware warranty covers hardware. Every drive fails eventually, new or refurbished, and no warranty brings data back. If the contents matter, they must exist in more than one place.
