00AJ470 Lenovo S3500 480GB SATA 3.5in MLC Enterprise Value SSD

Lenovo part 00AJ470 is the S3500 480GB SATA 3.5" MLC HS Enterprise Value SSD for System x, feature code A56E. It holds 480GB in a 3.5-inch form factor and ships on a 3.5-inch hot-swap tray.

Lenovo built the S3500 family on Intel 20 nm MLC NAND with a 6 Gbps SATA interface. Feature list: AES-256 encryption, full data path protection, power loss data protection, thermal throttling and S.M.A.R.T.; typical draw is 5 W and read and write latency are 50 and 65 microseconds.

Per the guide's table, the 480GB model reaches 75,000 read IOPS and 11,000 write IOPS (4 KB), streams at 500 MBps read and 410 MBps write (128 KB) and is rated for 275 TB written.

Endurance is the figure to plan around. Lenovo defines TBW as the total bytes of written data the drive is rated to complete, and notes that reaching it does not cause immediate failure, but the drive later goes into read-only mode at end of life.

Server support in the Lenovo guide: the System x3630 M4 (7158), with both the original and E5-2400 v2 processors. Lenovo's Configuration and Options Guide of 17 January 2017 also lists it for the x3500 M5 (5464) and x3550 M5 (5463 and 8869), marked with an asterisk as withdrawn.

Fit check: 00AJ470 needs a 3.5-inch hot-swap bay in a listed server; check feature code A56E on configuration records. Neighbouring options are 00AJ465 and 00AJ475.
