I recently got my hands on a factory recertified Seagate Exos 2x14 Mach 2, Model ST14000NM0121. I couldn't find a datasheet for this exact model. Unfortunately, for this whole class of drives it is hard to get data sheets, manuals or actual drives at a reasonable price. This is a multi actuator drive, which also gets nicely reported by the kernel:

Performance is as expected, which the read/write performance dropping steadily like any hdd, but jumping back to its initial speed after 50% drive capacity and then dropping again.

Please find attached the output of smartctl -x /dev/sdX I will also attach the output of openSeaChest_SMART for reference.

Please find attached the output of smartctl -x /dev/sdX The marketing name is Kingston SSDNow 256GB The controller is a Sandforce SF-2281VB1-SDC, connected to 16 flash chips.

Please find attached the output of smartctl -q noserial -x -a /dev/sdX This seems to be a OEM version of the 840 Pro according to some internet research. The controller inside is a S4LN021X01 8030, connected to 4 flash chips and a DRAM.
