What wholesale buyers check before ordering drives
- Exact part number — capacity alone is not enough; interface, sector format and firmware family matter for mixing into an existing array.
- Enterprise duty class — Ultrastar-class drives are rated for 24/7 operation; desktop drives are not a substitute in arrays.
- Testing before shipment — functional verification on the seller’s own bench, with records on request.
- Written warranty — ours: a 90-day warranty from delivery on every unit.
- Export documents — commercial invoice, packing list and HS code issued with the shipment.

Enterprise drive types we supply
- SAS enterprise HDDs for dual-port storage arrays where the controller expects SAS
- SATA enterprise HDDs for the broadest compatibility, in capacities from the 4TB class to 16TB and above
- NVMe enterprise SSDs for flash-backed arrays and high-IOPS workloads
Matching drive interface to your array
- SATA, SAS and NVMe are not interchangeable — the controller has to support the media
- A SAS-only controller cannot attach NVMe, and a tri-mode controller handles all three
- Check the backplane connector and the bay type, not just the drive label
Why enterprise drives rather than consumer drives in a server
- Error correction, vibration tolerance and workload ratings differ from the consumer line
- Consumer drives in a hot, vibration-heavy rack fail far earlier than their rating suggests
- Enterprise drives with the right endurance rating match the workload they are asked to do
How we test and document every drive
- Each unit is checked for surface defects, re-seated and confirmed on the test line before shipment
- We confirm the capacity, the model and the firmware level per unit
- The condition of each unit is stated in the quote, with 90-day warranty from delivery

Frequently Asked Questions
Can you supply enterprise hard drives in wholesale volume?
Yes. Send the model, the capacity and the quantity and we will confirm what we can allocate in a single batch, with batch pricing applied and the condition of each unit stated in the quote. Bulk processing takes additional time and we notify you of the estimated ship date on confirmation.
What is the difference between SAS and SATA enterprise drives?
SAS is the dual-port, full-duplex interface used in data center arrays, and it handles a drive failing without dropping the path. SATA is single-port and half-duplex, and it is the more broadly compatible and less expensive option. The deciding factor is the controller and backplane in your chassis.
Can I use NVMe SSDs with my existing RAID controller?
Only if the controller is tri-mode. A SAS-only controller such as the 9361 cannot attach NVMe drives at all. If the chassis has NVMe bays you need a 9460, 9500 or 9600 class controller, or a dedicated NVMe HBA. Tell us the controller and we will confirm the combination.
Why should I use enterprise drives instead of consumer drives in a server?
Error correction, vibration tolerance, workload rating and the firmware behaviour under sustained multi-drive workloads all differ. A consumer drive in a hot, vibration-heavy rack fails far earlier than its rating suggests, and the failure is often less graceful than a drive designed for the environment.
How do you verify a used enterprise drive?
Each unit is checked for surface defects and confirmed on our own test line, with the capacity, model and firmware level recorded per unit. We state the condition of each unit in the quote, and every unit carries a 90-day warranty from delivery.
Do you supply SSDs as well as HDDs?
Yes, NVMe enterprise SSDs are available alongside the SAS and SATA hard drives, for flash-backed arrays and high-IOPS workloads. Send the model and quantity and we will confirm what we can allocate and quote it per part number.
