ATA IV
These disks cannot operate reliably at ATA 100 on RCC/ServerWorks IDE controllers.
The drivers of these controllers blacklist the disks and limit their operation to ATA 66.
(S)ATA V (Plus)
The SATA models have many problems including random data loss (such as disappearing partitions).
These disks cannot work with some Silicon Image SATA controllers.
The drivers of these controllers blacklist the disks and limit the maximum sectors of each transaction below 8KB (15 sectors).
That workaround has a large performance impact.
7200.7 (Plus)
The NCQ capable SATA models do not have NCQ even though their product manual and firmware claim to support it
7200.10
The SATA models of this family with firmware 3.AAK[codename GALAXY] or older
(e.g. 3.AAE[codename TONKA]) have introduced a firmware (microcode) bug:
There is a performance anomaly using hdparm with NCQ queue depth 31 in AHCI mode.
Speed test measures only 55~64 MB/s (expected: >70~75MB/s).
7200.11
Disks may not show and utilize all the cache.
FLUSH_CACHE commands may timeout when NCQ is used.
There is a performance anomaly using hdparm with NCQ queue depth 31 in AHCI mode.
Speed test measures only 45~50 MB/s (expected: >100~110 MB/s).
Disks may be inaccessible at power on.[
