Toshiba Publishes List of Hard Drives With SMR Technology
Following Western Digital's footsteps, Toshiba has posted online the list of the hard drives that are based on the slower shingled magnetic recording (SMR) technology.
Western Digital, Seagate and Toshiba made headlines lately for not being totally transparent about the fact that some of their hard drives were fabricated with SMR.
Western Digital released a list of WD hard drives that leverage the slower technology.
Here is the list of the Toshiba SMR HDD models:
| Model | Capacity | Form Factor |
|---|---|---|
| Toshiba P300 | 6TB | 3.5-inch |
| Toshiba P300 | 4TB | 3.5-inch |
| Toshiba DT02 | 6TB | 3.5-inch |
| Toshiba DT02 | 4TB | 3.5-inch |
| Toshiba DT02-V | 6TB | 3.5-inch |
| Toshiba DT02-V | 4TB | 3.5-inch |
| Toshiba L200 | 2TB | 2.5-inch |
| Toshiba L200 | 1TB | 2.5-inch |
| Toshiba MQ04 | 2TB | 2.5-inch |
| Toshiba MQ04 | 1TB | 2.5-inch |
SMR is typically used to produce hard drives with high densities, although Toshiba is utilizing the technology on 6TB, 4TB and even 1TB and 2TB drives.
According to Toshiba, SMR has opened the doors for hard drive manufacturers to increase the capacity of their conventional platter drives. However, SMR has a negative impact on a hard drive's performance, particularly in workloads that involve continuous random writing.
