-The Input/Output Operations Per Second (IOPS) and throughput limits for Azure Premium solid-state drives (SSD), Standard SSDs, and Standard hard disk drives (HDD) that are 1024 GB and larger can be increased by enabling performance plus. Enabling performance plus improves the experience for workloads that require high IOPS and throughput, such as database and transactional workloads. There's no extra charge for enabling performance plus on a disk.
+The Input/Output Operations Per Second (IOPS) and throughput limits for Azure Premium solid-state drives (SSD), Standard SSDs, and Standard hard disk drives (HDD) that are 513 GiB and larger can be increased by enabling performance plus. Enabling performance plus (preview) improves the experience for workloads that require high IOPS and throughput, such as database and transactional workloads. There's no extra charge for enabling performance plus on a disk.
 
 Once enabled, the IOPS and throughput limits for an eligible disk increase to the higher maximum limits. To see the new IOPS and throughput limits for eligible disks, consult the columns that begin with "*Expanded" in the [Scalability and performance targets for VM disks](disks-scalability-targets.md) article.
 
 ## Limitations
 
-- Can only be enabled on Standard HDD, Standard SSD, and Premium SSD managed disks that are 1024 GiB or larger.
+- Can only be enabled on Standard HDD, Standard SSD, and Premium SSD managed disks that are 513 GiB or larger.
 - Can only be enabled on new disks.
     - To work around this, create a snapshot of your disk, then create a new disk from the snapshot.
 - Not supported for disks recovered with Azure Site Recovery or Azure Backup.
