Context:

NASCompares incorrectly claims these use SMR. In reality, they’re basically the same as the SkyHawk ST4000VX007 and IronWolf ST4000VN008 minus the « enhancements » those two have.

This was before BarraCuda Compute got its SMR upheaval from the likes of the ST2000DM008, ST4000DM004, etc., which effectively butchered the series. These 4 TB drives are based on the V9 platform, whereas lower capacity multi-platters (ST2000DM006 and ST3000DM008) used a refreshed version of the Grenada platform, which Seagate aptly named Grenada BP2 Refresh. The ST500DM009 and ST1000DM010 on the other hand, which remained in data sheets until very late, were based on Pharaoh Oasis, the last platform Seagate produced that still used the then-ancient contact start stop (CSS) head parking tech. What all of these drives have in common is they use CMR, as compared to newer « hot air » BarraCudas that all screw you over with SMR.

Conventionally enough, this ST4000DM005 also came from a Dell machine, as indicated by the presence of « DP/N » and ‘DS/N » as well as the usual Dell-esque « info box » and a matrix barcode.
