SSD cache acceleration
SSD caching can greatly boost IOPS performance. It is perfect for 
improving the overall workflow of IOPS-demanding applications 
such as File Servers and online transaction processing (OLTP) 
systems. SSD caching allows SSDs to work with HDDs on the 
same NAS to achieve higher random access performance with 
lower cost.
The Turbo NAS business series supports SSDs which can be used 
for caching. The random IOPS performance of storage volumes 
can remarkably boost. It is perfect for improving overall workflow 
of random IOPS demanding applications such as database and 
virtualization. The TS-ECx80 series supports two extra internal 
cache ports to install mSATA flash module (optional purchase). The 
internal cache port design reserves the space of hard drive tray 
for more storage capacity.

When a hard drive fails, a RAID configuration will enter a degraded 
mode that risks data protection. During this time if more hard drives 
fail, depending on the RAID level used, the data stored in the RAID 
group will be risking a data corruption crisis.
It takes time for RAID rebuild no matter by manual or by hot-spare 
drive to replace the failed hard drive(s). The shorter the RAID rebuild 
time, the shorter the RAID configuration will be in degraded mode 
and the less risk for data corruption. Here we will list the common 
RAID rebuild time for comparison.
When using eight 4TB SATA HDD in RAID 6, the RAID rebuild time 
after replacing a failed hard drive is approximately 3-7 days; but 
it takes only 12-24 hours when using SAS hard drives with SSD 
caching. 
Using SAS-enabled NAS systems with SAS hard drives can 
effectively shorten the RAID rebuilt time. Coupled with an SSD 
acceleration cache to share the IO process loading, the RAID rebuild 
time can be significantly shortened, meaning lower risk of data 
corruption to safeguard your important data.

Locate hardware easily
With just a click, IT administrators can easily locate the NAS, RAID 
expansion enclosures, hard drives, and RAID groups in the server 
room by the beep sound or lighting on the NAS. It is especially 
useful when managing a big server room with multiple NAS 
systems.
Missing mode protection                          
When the disconnection of a RAID expansion enclosure is 
detected, the Turbo NAS blocks IO access to protect data. The 
system can recover from the missing mode to the normal state with 
data staying intact.
TS-ECx80 series supports two extra internal cache ports.
