Toshiba Joins 24 Tb CMR And 28 TB SMR Disk Drive Club
Blocks&Files, Tuesday, September 10th, 2024
Toshiba has caught up - again - with Seagate and Western Digital by announcing sample shipping of Mx11 family 24 TB conventional magnetic recording (CMR) and 28 TB shingled magnetic recording (SMR) disk drives.
Seagate first announced its 24 TB CMR drive, the Exos X24, in October last year. It later added the Exos X28 SMR drive, which was slightly overshadowed by its Exos HAMR announcement in January that highlighted conventional 24 and 30 TB HAMR drives and a 32 TB shingled drive. These are not actually shipping, being in the customer qualification stage.
Western Digital started shipping Ultrastar DC HC580 24 TB CMR and DC HC680 28 TB SMR disk drives in November last year. Up until now, Toshiba's maximum capacity drive has been the MG10F 22 TB CMR, announced in September 2023. There was previously no Toshiba SMR drive in this nearline, mass-capacity class of product.
