Are they eavesdropping on the Martians’ conversations?
SSD maker Phison recently shared fresh details on the flash that sits inside the Mars Perseverance rover with Reg sister title Blocks & Files, and also talked up the 8TB SSD planned for use in Lonestar Data Holdings' audacious lunar datacenter mission. The manufacturer of the 8GB industrial-grade PSS4A111-8G uSSD that sits …
> space is not a break-and-fix environment. If the SSD fails, then the rover's imaging system stops working.
??? Never heard of RAID? Redundant storage?
I know every milligram is precious when 50M miles away. But loss of a mission for want of a second (or third?) drive seems like an obvious design study. RAID (any flavor you like) has been a 10-cent extra in earthly PCs for a decade.
Remark further along suggesting that "traditional hard disk"s are disfavored seems like blather. Aside from weight and standby power, don't Winchester heads still fly on air-cushion? Mars' 1% air may be too-too thin? Sealed air requires NO-leak pressure chamber? Also most earth-market bearings are not metal but metal oxide where it counts (exposed surface). After a week outgassing in space, metal-on-metal spinners tend to weld, seize.
Sound microphones give data about the very thin air. You can learn a lot by listening. (But not if you rely on a dead drive to relay files back for analysis.)
