DOS Utility Limitations
1) The DOS Utility is not compatible with pure SCSI or SATA NVIDIA/LSI/AMD chipset
drivers.
2) AHCI or ATA mode must be enabled in the BIOS during PC boot up.
3) The DOS utility may not work consistently on PCs with chipsets other than the
ones listed above.
4) The DOS Utility may hang if the SSD is removed on PCs that do not support the hot
plug feature (e.g. ICH5/6 chipsets).
5) The DOS Utility will not work with devices attached via SATA 6Gbps (SATA III)
operating in IDE mode.
RAPIDmode Limitations
1) RAPIDmode accelerates only one SSD even though user has several Samsung
SSDs(850 EVO, 850 PRO, 840 EVO, 840 PRO, and 840 EVO mSATA).
2) If there are two identical SSDs connected, RAPIDmode may accelerate the
incorrect SSD.
3) RAID Mode sets is not supported as an accelerated drive.
4) After uninstalling RAPIDmode, if the system is restored to a prior state in which
RAPIDmode was installed, RAPIDmode will be started in a disabled state.
5) NVIDIA Storage controller is not supported.
6) During RAPIDmdoe Enable/Disable operation: Do not disconnect the target SSD,
Do not kill the application.
7) F/W download and Secure Erase is not allowed in case of RAPIDmode enabled SSD.
8) If fast startup is enabled on windows 8 and 8.1 machines, RAPIDmode
enable/disable requires system restart. Shutdown followed by turning-on the
power will not activate RAPIDmode enable/disable. By default fast startup is
enabled.
9) Flush command of operating system and/or application may cause variation in
performance when RAPIDmode is enabled(especially when Write-Cache Buffer
Flushing is On).
10) Sometimes on AMD PC with AMD and ASMedia storage controllers it was found
that the IOs takes a longer time to complete. In such cases if Rapid was
enabled, it may get automatically disabled due to such IO errors. It may
display "Rapid is in inactive state". User has to reboot the PC to enable the
Rapid back.
11) If multiple iterations of Read and Write are performed, RAPIDmode may
become inactive due to system internal errors on some of the AMD /
AsMedia Controller or Driver
.
12) RAPIDmode can't be guaranteed on the target SSD with non-NTFS file
