P23449-B21 is the HPE 16TB SATA 6G Business Critical 7.2K LFF low profile hard drive. It is a helium-filled 512e drive with ISE, made for 3.5-inch large form factor bays in HPE ProLiant servers.
The drive reaches 258 MiB/s sequential throughput. Random 128 KiB performance is 105 IOPS for reads, 115 IOPS for a 70% read and 30% write mix, and 125 IOPS for a 50/50 mix. Power draw is 5.5 W idle, 9.1 W on random reads and writes, 7.8 W on sequential reads and 8.4 W on sequential writes. Helium is one seventh as dense as air, and helium drives tend to use less power and run cooler and quieter.
It is an orderable LFF low profile SATA option for the ProLiant DL380 Gen10 Plus, DL385 Gen10 Plus, DL360 Gen11, DL380 Gen11, DL385 Gen11 and ML350 Gen11. The same SATA low profile line continues with 12TB 881787-B21, 20TB P53554-B21, 24TB P68585-B21 and 26TB P80578-B21. The 16TB SATA drive in a Smart Carrier is P23857-B21, and the 16TB SAS low profile drive is P23608-B21.
The spare numbers are P25244-001 for the low profile 16TB SATA 3.5-inch ISE helium drive and P25246-001 for the Smart Carrier version.
