In September 2025, TrendForce reported a huge jump in nearline hard drive lead times. They went from a few weeks to more than 52 weeks. A year later, the wait hasn't shrunk. If you run Dell PowerEdge or HPE ProLiant servers, that hits close to home. A drive fails. The replacement is backordered. Nobody can say when it will arrive.

As of October 2026, the server hard drive shortage is real, and it won't end soon. Seagate says it has already allocated most of its nearline capacity into 2028. You can still keep your servers healthy. Audit your drives and keep spares. Match part numbers, and use tested pre-owned drives while new ones are scarce.

Why the nearline HDD shortage in 2026 got this bad

Nearline drives are the high-capacity drives that data centers use for bulk storage. AI changed who gets them first.

AI services create and keep huge piles of data. Cloud giants store it on nearline drives, because nothing else is as cheap per terabyte. So they signed long contracts. On its July earnings call, Seagate said it has now allocated the vast majority of its nearline capacity into 2028. Western Digital's CEO said earlier this year that the company was pretty much sold out for 2026. Its long-term deals reach into 2027 and 2028.

Supply can't catch up fast. TrendForce noted that the big makers hadn't expanded capacity in recent years. Seagate says it is keeping its drive count flat and packing more data onto each disk. That adds exabytes. It doesn't add drives.

Toshiba is trying to change that. It is a distant third, with about 11% of the market. Seagate and Western Digital hold about 44% each. Blocks & Files reports that Toshiba is spending about $380 million to catch up. It plans to nearly double its Philippines plant's yearly output in terabytes by fiscal 2027, versus fiscal 2025. That helps, but Toshiba starts far behind.

How long are enterprise HDD lead times right now?

For new nearline drives, published figures run from more than 52 weeks to as long as two years.

Your own wait depends on the part number and your supplier's stock. Some drives are in stock today and gone next week. Quotes can expire fast. Ask for a confirmed date in writing. An estimate isn't a date.

Server makers feel it too. On Dell's May earnings call, COO Jeff Clarke named the top supply limits. They were DRAM, NAND, and CPUs, then hard drives. He also said most of Dell's installed base still runs 14th generation servers or older. Those servers will keep needing drives.

RAM is under the same strain. Our HPE ProLiant Gen11 DDR5 price surge guide covers that side.

Which drives are hardest to find?

The squeeze is worst for large 3.5-inch nearline drives, the kind data centers use by the thousands. But prices are up across the board. Tom's Hardware reported in February that many hard drive models had jumped 46% on average since September 2025.

One 2.5-inch family may be drying up too. An August notice from Advantech, an industrial computer maker, says Seagate discontinued its Exos 10K 2.5-inch drives. The notice lists 600GB, 1.2TB and 2.4TB SAS models. It sets end of life at July 5, 2026, with a final supply window that closes November 30. Many Dell and HPE servers run 2.5-inch 10K SAS drives. Check with your supplier before you plan around them.

What to do when new enterprise drives are backordered

Here is the plan we would follow.

1. Check what you have. Pull a drive list from iDRAC on Dell or iLO on HPE. Note each model, capacity, speed, interface, and firmware. Flag any drive with a predictive failure alert. Those are your first replacements.
2. Count your spares. Keep at least one spare of every drive type you run. If a second failure would take down the array, keep two. Honestly, a spare on the shelf beats any rush hunt.
3. Protect the data first. A rebuild puts stress on every drive in the array. Confirm your backup works before you start. Check the failed bay twice before you pull anything. Pulling a healthy drive from a degraded array can take it offline. Big drives can take a day or more to rebuild. For large arrays, consider RAID 6 or RAID 10.
4. Match the exact part number. Same size is not the same drive. The next section shows what to check on Dell and HPE servers. Not sure if your bays take SAS or SATA? Our SAS vs SATA server hard drives guide explains the difference.
5. Look at tested pre-owned drives. Pre-owned server hard drives come from retired servers or surplus stock. They skip the new-drive queue. Don't expect fire-sale prices while new drives are scarce. Ask any seller for the SMART report, power-on hours, and warranty terms. A drive sold as new should show close to zero hours. Check that the label's model and serial number match what the drive reports.
6. Be flexible on capacity. If the exact size is gone, a larger drive of the same type often works. The array uses only the old drive's size, so the extra space sits idle. That still beats running degraded.
7. Use SSDs where they pay off. Flash makes sense for hot data. It isn't a cheap way to replace bulk capacity. TrendForce expects NAND contract prices to rise 15% to 20% in the fourth quarter. It also says enterprise SSDs are the only memory type where price growth is speeding up. Keep SSDs and hard drives in separate arrays.
8. Free up space and plan early. Archive cold data, clear old snapshots, and turn on compression or dedupe. Then send your supplier a 12-month forecast. Approve two or three alternates, so you can accept a quote the day it arrives.

Dell PowerEdge SAS hard drive vs HPE ProLiant SAS hard drive: what to match

Check these four things before you accept any replacement.

A flagged drive often still runs. You may see warnings, lose some health monitoring, and get no support from Dell or HPE. Before you mix speeds or interfaces in one array, read your controller guide.

Server hard drive shortage Common Questions

When will the server hard drive shortage end?

No one has a firm date. Seagate says it has allocated the vast majority of its nearline capacity into 2028. It also says customers want to plan through 2029 and beyond. Western Digital has deals into 2028. Data Center Dynamics said in March that drives were effectively sold out through 2027. Plan for tight supply through at least 2027.

How long are enterprise HDD lead times?

For new nearline drives, reports range from over 52 weeks to two years. Small quantities depend on the supplier and the part number. Ask for a confirmed date in writing.

Can I replace a failed SAS drive with a bigger one?

Often, yes. The interface, speed, sector format, and carrier must still match. The array uses only the old drive's size, so the extra space sits idle.

Can I use a drive without Dell or HPE firmware?

Often it runs. But the controller may flag it, you can lose some monitoring, and the server maker may not support it. An exact OEM part number avoids the problem.

Are pre-owned server drives safe?

They can be, when tested. Ask for the SMART report, power-on hours, and warranty. Use them in a redundant array with a working backup.

A simple plan for this quarter

Don't wait for the nearline HDD shortage to ease. Seagate has already allocated most of its capacity into 2028. Relief looks far off. This month, list every drive and part number you run. Get one spare of each type. Send your supplier a forecast. And if you want a second pair of eyes on a part number, contact CPU Republic. We carry new and pre-owned storage hardware, including Dell and HPE SAS drives.
