Western Digital Black SN850X provides 4TB of storage in an M.2 2280 form factor. It delivers sequential read speeds up to 7300 MBps and sequential write speeds up to 6600 MBps. Random read performance reaches 1,200,000 IOPS.
Form factor and generation interface dictate compatibility and speed. Prioritize drives with DRAM caches for OS boot drives, as DRAM-less drives can slow down significantly during heavy multitasking. Available from $679.
Solid State Drives (SSDs) have no ongoing costs and consume minimal power. Their cost of ownership is entirely the upfront price per gigabyte.
Common Failure Modes
SSDs have no moving parts, making them immune to physical shock. Failures occur through flash memory wear-out from writing massive amounts of data or sudden controller death.
Form factor and generation interface dictate compatibility and speed. Prioritize drives with DRAM caches for OS boot drives, as DRAM-less drives can slow down significantly during heavy multitasking.
SSDs have a finite number of write cycles, usually measured in Terabytes Written (TBW). For average consumers, this limit takes many years to reach.
