Read Intensive SSDs and Mixed Use SSDs have similar read and write IOPS performance, but the key difference between them is their endurance (or lifetime) — that is, how long they can perform write operations because SSDs have a finite number of program/erase (P/E) cycles. Read Intensive SSDs typically have a better cost per read IOPS ratio but lower endurance and performance compared to Mixed Use SSDs. The TBW value assigned to a solid-state device is the total bytes of written data (based on the number of P/E cycles) that a drive can be guaranteed to complete (% of remaining P/E cycles = % of remaining TBW). Reaching this limit does not cause the drive to immediately fail. It simply denotes the maximum number of writes that can be guaranteed. A solid-state device will not fail upon reaching the specified TBW. At some point based on manufacturing variance margin, after surpassing the TBW value, the drive will reach the end-of-life point, at which the drive will go into a read-only mode.
For example, the ER2 480GB drive has an endurance of 870 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 477 GB of writes per day, which is equivalent to 1.0 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 795 GB of writes per day, which is equivalent to 1.7 full drive writes per day.

Warranty
The ER2 M.2 SSDs carry a one-year, customer-replaceable unit (CRU) limited warranty. When the SSDs are installed in a supported server, these drives assume the system’s base warranty and any warranty upgrades.
Solid State Memory cells have an intrinsic, finite number of program/erase cycles that each cell can incur. As a result, each solid state device has a maximum amount of program/erase cycles to which it can be subjected. The warranty for Lenovo solid state drives (SSDs) is limited to drives that have not reached the maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the SSD product. A drive that reaches this limit may fail to operate according to its Specifications.
Physical specifications
The ER2 M.2 SSDs have the following physical specifications:
- Length: 80 mm
- Width: 22 mm
- Thickness: 3.65 mm
- Weight: 10g
Operating environment
The ER2 M.2 SSDs are supported in the following environment:
- Temperature, operating: 0 – 70 °C (32 – 158 °F)
- Temperature, non-operating: -40 to 85 °C (-40 – 185 °F)
- Relative humidity: 5 – 95% (noncondensing)
- Maximum altitude: -300 – 4,572 m (-1,000 to 15,000 feet)
