3.5" Hard Drives
3.5-inch (LFF) SAS and SATA hard drives are the capacity drives of the server world: most spin at 7,200 RPM as NL-SAS or SATA models, and the size also includes 15K RPM SAS performance drives. Check each listing for self-encrypting (SED) and 4Kn or 512e advanced-format builds. Match the server maker's part number and the carrier your LFF bay takes; every drive is tested on arrival and before shipment in our lab, with the warranty term shown on the product page.

3.5-inch drive classes
A 3.5-inch server drive is almost always a 7,200 RPM capacity drive, built as nearline SAS for SAS controllers or as SATA; the 15K class also exists in 3.5-inch, up to 600GB in Seagate's data sheet:
| Class | Interface and ports (Seagate) | Spindle speed | Typical role |
|---|---|---|---|
| Nearline SAS | 12Gb/s SAS, dual-port | 7,200 RPM | High-capacity density RAID storage |
| Enterprise SATA | 6Gb/s SATA, single-port | 7,200 RPM | Capacity storage on SATA ports or behind SAS controllers |
| 15K SAS, 3.5-inch | 6Gb/s SAS | 15,000 RPM | Business and transaction processing |
Many capacity drives come in 512e and 4Kn sector formats as well as 512n. Dell's PERC 11 guide does not allow 512-byte and 4 KB native drives in the same virtual disk, and it supports 4K drives only in UEFI boot mode, so match the format of the drives already in the array.
Which servers take 3.5-inch drives
Dell documents these 3.5-inch bay counts and drive lists by PowerEdge generation:
| PowerEdge generation | 3.5-inch bays Dell documents | 3.5-inch drives in Dell's lists |
|---|---|---|
| 12th | Up to 8 on the standard 2U chassis, 12 on the xd | Hot-swappable 3.5-inch drives |
| 14th | 4 in 1U; 8 or 12 in 2U, plus 2 rear and 4 mid-bay on the xd | 7.2K SATA from 1 to 16TB, 7.2K SAS from 1 to 10TB |
| 15th | 12 in 2U | 7.2K SATA and SAS from 2 to 18TB |
| 16th | 12 in 2U | 7.2K SATA and SAS from 2 to 20TB |
HPE's DL380 Gen10 QuickSpecs give that server an 8-bay or 12-bay LFF front, and the 12-bay chassis can add a 4-bay LFF mid-plane and a 3-bay LFF rear cage.
Carriers for 3.5-inch bays
A 3.5-inch bay takes its drive in a 3.5-inch carrier, and Dell's 3.5-inch drive adapter lets the same carrier hold a 2.5-inch drive when a smaller SSD or SAS drive has to go in a large-form-factor slot. Shop carriers under hard drive caddies and trays, and 2.5-inch drives are on 2.5-inch hard drives. For the difference between the two interfaces, read SAS vs SATA.
