Enterprise Storage Hub
Pro Disk Network stocks 180,000+ enterprise storage SKUs across every form factor (2.5", 3.5", M.2, U.2), every interface (SAS, SATA, NVMe, Fibre Channel), and every capacity from 146GB legacy drives to 30TB modern enterprise SSDs. This hub is the navigation map: pick your topic, browse the dedicated category, read the buying guide, or jump directly to top SKUs. All shipping today from US warehouses.
Storage by Form Factor and Interface
Storage selection starts with form factor (does it physically fit?) and interface (does the controller speak its protocol?). Drives on Pro Disk Network are organized by both:
- Server Hard Drives (SAS, SATA) — 12,000+ enterprise SAS/SATA drives — 10K/15K RPM, 2.5" SFF and 3.5" LFF
- Enterprise SSDs — 4,500+ datacenter SSDs from Samsung PM/SM series, Intel D3/D5/D7, Kioxia, Micron
- Internal Hard Drives — Workstation and entry-server SATA drives
- External Hard Drives — USB / Thunderbolt / eSATA external storage
- Hard Drive Enclosures — JBOD shelves, disk arrays, single-bay enclosures
- SSD/HDD Accessories — Caddies, brackets, mounting hardware, screws
Storage by Brand

Frequently Asked Questions
What's the difference between SAS, SATA, and NVMe drives?
SAS uses the Serial Attached SCSI protocol with dual-port redundancy and higher MTBF — meant for enterprise OLTP/database workloads. SATA is the consumer-derived single-port interface used widely in backup tier and warm storage. NVMe runs directly over PCIe with no SCSI translation layer, delivering 3-7GB/s per drive vs SATA's 550MB/s ceiling — meant for latency-sensitive workloads (databases, VDI, real-time analytics).
How long do enterprise hard drives typically last?
Enterprise SAS drives average 5-7 years MTBF in datacenter conditions. SATA enterprise drives average 4-6 years. NVMe SSDs are limited by TBW (terabytes written) endurance rather than years — typically 3-5 year service life. Annual failure rates above 3% indicate replacement time.
Will any drive work in my server?
Drives need to match: (1) form factor — 2.5" SFF or 3.5" LFF (caddy bay determines), (2) interface — SAS/SATA/NVMe must match controller, (3) capacity — most controllers support all common capacities. Some servers also require validated firmware (Dell PowerEdge with PERC controllers, HP ProLiant with Smart Array). Email sales@prodisknetwork.com with your server model for a fitment check.
Do you offer refurbished enterprise drives?
Yes. All refurbished drives at Pro Disk Network are: (1) cleared with a 7-pass DoD wipe, (2) tested for bad blocks and SMART health, (3) re-warranted under Pro Disk Network's 90-day standard or 1-year B2B warranty. Each drive ships with a fresh firmware load and serial number traceability. Refurbished costs typically run 30-50% of new.
What sizes and speeds do you have?
We stock capacities from 146GB (legacy 15K SAS) through 30TB (modern enterprise SATA). Speeds range from 7.2K RPM (capacity-optimized) through 15K RPM (legacy performance), with most modern enterprise drives in the 10K RPM and SSD tiers. NVMe drives top out at sustained 6-7 GB/s read for PCIe Gen4 enterprise SKUs.
How fast does enterprise storage ship?
Single drives ship same business day on orders placed before 2pm ET. Bulk orders (10+ drives) ship same-day if in inventory; pallet-quantity orders typically dispatch within 24-48 hours. International shipping to 31 countries via FedEx/DHL Express, 3-7 business days.
How to Pick the Right Enterprise Storage for Your Workload
A step-by-step procedure to apply when selecting hardware in this category:
- Classify the workload type: Bulk/archive/backup = SATA. OLTP/database/virtualization = SAS or NVMe. Real-time analytics or VDI = NVMe. Mixed workloads benefit from a tiered approach (NVMe cache + SAS/SATA capacity).
- Calculate IOPS and throughput requirements: Pull metrics from your monitoring tool. Under 200 sustained IOPS = SATA is fine. Above 500 sustained IOPS = SAS or SSD. Throughput above 1GB/s per drive = NVMe only.
- Verify controller compatibility: Match drive interface (SAS/SATA/NVMe) to your RAID controller capabilities. Dell PERC, HP Smart Array, LSI/Broadcom MegaRAID, Adaptec all have specific support matrices.
- Match form factor to chassis: 2.5" SFF requires SFF caddies; 3.5" LFF requires LFF trays. Many servers have a fixed bay mix that determines what you can install.
- Plan capacity with growth headroom: Buy at least 40% above current usage to avoid hot-swap thrashing. Enterprise drives are most cost-efficient at the 1.92TB-4TB sweet spot (best $/TB).
- Order one drive to validate, then bulk-order: Buy a single drive, install it, run a full benchmark and SMART check against your actual workload. Then commit to fleet purchase only after validation.
