The SKU: YKT0W (or 0YKT0W) is a Dell  900GB 15K RPM SAS 12Gbps 2.5-inch (SFF) hard drive. Based on its technical specifications, its exact functional equivalents, should you require to replace one, depend on the manufacturer and the system it is being installed in.

1. Physical Equivalents (Direct Manufacturer Models)

Dell does not manufacture the drives; they rebrand drives from major manufacturers. The YKT0W is primarily a rebranded Toshiba AL14SXB series drive with the correct Dell proprietary firmware.

These are the same drives without the Dell sticker, these are the equivalents:

• ::Toshiba Model: AL14SXB90ENY
• ::Seagate Model: ST900MP0026 (Enterprise Performance 15K v6)
•  

2. Dell Equivalent Part Numbers

Dell often uses different part numbers (DP/Ns) for the exact same drive spec to track different manufacturing batches or firmware versions. The following are direct functional equivalents within the Dell ecosystem:

• ::400-ATIQ (Marketing/Option Part Number)
• ::400-AUWP
• ::NMJD8 (Alternative Spare Part Number)
• ::XTH17 (Common alternative for 14G/15G servers)
•  

Key Features:-

• :: Always Online: Designed for continuous operation, fulfilling requests from multiple users simultaneously.
• :: Constant Growth: Supports ongoing expansion and maintenance while in operation.
• :: High Performance: Delivers the highest performance needed to meet enterprise demands.
•  

Performance Benefits:-

• :: Accelerated I/O Operations: Completes more transactions faster, even during peak demand.
• :: Increased Capacity: At 900 GB, stores 50% more mission-critical data than other 15K HDDs.
• :: Cost Optimization: Higher capacity at a lower cost compared to high-performance alternatives.
• :: Predictable Performance: Up to 27% faster than previous generations, protecting data from corruption due to unexpected power loss.
• :: Drive Format Support: Supports all formats, including 512 native and a single Fast Format™ model for advanced formats (4Kn and 512e), simplifying HDD management.

A Note on Sector Formats:

These drives, DPN:YKT0W are 512n (512 native) drives. While a 900GB 15K drive with a 512e (Advanced Format) or 4Kn format might look identical, mixing 512n and 512e drives in the same RAID virtual disk can cause array errors or performance issues.

Always check the "512n" vs "512e" label on the drive sticker.
