What is Intel Smart
Response Technology?
®
We store a lot of diverse types of content on our PCs: Movies, photos, music, documents—the list goes on. Intel® Smart Response Technology1 enables either a dual drive (a lower-cost, small-capacity SSD used in conjunction with a low-cost, highcapacity hard disk drive) or a solid state hybrid drive (SSHD) to provide a high-performance, cost-effective storage solution. As
a result, you can fast-track your favorites—faster access to applications and files that you use the most. Intel Smart Response
Technology is also great for gaming enthusiasts—game launch times are faster2,3 than with a traditional hard disk drive (HDD).
Key Benefits
‒ Faster system startup, application
performance and faster game loads2,4
‒ Best performance per GB storage
solution at affordable prices
‒ Lower power consumption than
standard HDD
‒ Easy to set up and maintain
For HDD, Intel Smart Response Technology maximizes system storage I/O
performance and power savings by implementing an intelligent cache policy
that stores applications and files data
blocks that will benefit most from caching onto the SSD. Intel Smart Response
Technology differentiates between
high-value data (application, user, and
boot data) and low-value data, like that
which may be caused by a virus scanner
or other similar one-touch data. Onetouch data, as the name suggests, is
data that is accessed from the drive for
a one time use only. This type of data
typically does not benefit the user from
caching, and therefore is not inserted
into the cache. Purely sequential data
streams (example: streaming a movie
file from disk, or large file copies) do
not get a big boost from the SSD and
may bypass the cache, since these
often consist of a large amount of
one-touch data unlikely to benefit from
caching. Additionally, the bandwidth
required for audio and video streams
does not require SSD performance, so
we intelligently choose not to cache
and use up SSD capacity.
For SSHDs, Intel Smart Response
Technology’s caching policy provides
priority hints to the SSHD’s onboard
cache manager of data through the Hybrid Hinting feature, notifying the drive
which data would be best to store in the
NAND cache instead of the rotational
media.
The caching policy of Intel® Smart
Response Technology adapts to facilitate faster cache warm-up by taking
advantage of the well-known principles
of data locality to keep a persistent
working set of frequently accessed
data blocks on the SSD and retaining
that data across system shutdowns and
reboots.
Acceleration Modes
Intel® Rapid Storage Technology5 user
interface supports two modes of ac-
celeration for HDDs: Enhanced (writethrough) and Maximized (write-back).
Enhanced mode (write-through) is the
default mode of operation where acceleration is optimized for data protection. In this mode, all data is written to
the SSD and HDD simultaneously. In the
event the accelerated disk fails, there
is no risk of data loss, because the data
on the HDD is always synchronized with
the data in the SSD. Since this mode is
optimized for data protection, there is
a performance impact since all writes
slow down to HDD speeds. However the
HDD and SSD pair may be physically
separated without any special precautions to preserve data.
Maximized mode (write-back) enables
acceleration optimized for input/output
performance. This mode captures most
host writes into the SSD first and updates the copy on the HDD during available system idle periods. This enables
a considerable boost in write performance and also saves power. However,
Intel® Smart Response caching must be
disabled prior to HDD and SSD physical
separation. If it is unlikely that the HDD
and SSD may be physically separate or
an SSHD is being used, then maximized
mode is recommended for best performance and responsiveness.
SSD Requirements
Intel Smart Response Technology
requires a PCIe* or SATA based SSD in
conjunction with a traditional HDD or a
SSHD.
Discrete SSD Cache Requirements
Any SATA SSD can be used as a cache
provided it has a minimum capacity of
16GB. The system SATA controller must
be set to RAID mode via the system
BIOS and the SSD attached to an internal PCIe or SATA port of the computer.
There is no support for Intel Smart
Response Technology in AHCI mode.
Please refer to the platform specific
design guides for PCIe and SATA supported lanes.
SSHD Requirements
Intel Smart Response Technology supports SSHDs with a minimum capacity of 8GB that are compliant with the
SATA-IO Hybrid Information Feature.
The system controller must be set to
RAID mode via the system BIOS and the
SSHD attached to an internal SATA port
of the computer. There is no support
for Intel Smart Response Technology in
AHCI mode.
Other Features
Power-Up In Standby (PUIS) support
for Intel® Smart Connect Technology6
reduces HDD drive spin up, lowers system power consumption, and improves
battery life and reliability with disk spin
suppression during motion. When Intel®
Smart Connect Technology wakes the
system up to download fresh data, Intel
Smart Response Technology powers up
the SSD and keeps the HDD spun down.
A PUIS-enabled HDD is required to support this feature.
