Overview

Fifteen terabytes of SAS flash in a 2.5in bay: that is the ThinkSystem 4XB7A17056. It is a PM1643a on 12Gb SAS in Lenovo's Entry endurance class, hot-swap, built on Samsung 64-layer TLC V-NAND, and tracked by Lenovo as feature code BC4R.

At 1 DWPD the drive is rated for 28032 TB written. It reads and writes sequentially at 1000 MB/s and handles 230000 random read IOPS and 65000 random write IOPS. Typical power is 9 W reading and 12 W writing. MTBF is 2000000 hours, and there is no encryption.

In a server with only a few SAS bays, a drive of this capacity can hold an entire large data set, which makes it an option for consolidating many older disks. It favors read-dominated work such as archives, media and analytics inputs. Compatible systems are the ThinkSystem SR630, SR650, SR530, SR550, SR570, SR590, SR645, SR665, SR630 V2, SR650 V2, ST650 V2, SR670 V2, SD530, SN550 and SN850.

The 4XB7A17056 is available New, Refurbished and Used. New and Refurbished units carry a choice of 1 year or 3 years of warranty, and Used units carry 90 days.
