The Seagate IronWolf 110 is a solid-state drive in the 2.5" form factor, launched in 2019. It is available in capacities ranging from 240 GB to 3.8 TB. This page reports specifications for the 240 GB variant. With the rest of the system, the Seagate IronWolf 110 interfaces using a SATA 6 Gbps connection. The SSD controller is the SF-4500500021768 from Seagate, a DRAM cache chip is available. Seagate has installed 64-layer TLC NAND flash on the IronWolf 110, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The IronWolf 110 is rated for sequential read speeds of up to 560 MB/s and 345 MB/s write; random IO reaches 55K IOPS for read and 30K for writes.
At its launch, the SSD was priced at 80 USD. The warranty length is set to five years, which is an excellent warranty period. Seagate guarantees an endurance rating of 435 TBW, a good value.

Notes

Drive:

Given the SandForce's acquisition, SandForce made this controller marking it as "SF-4500". Furthemore, this drive has a small static SLC cache which shares space with the over-provisioning area.
