SSD Caching no no read & write caching for additional performance
Scalability mostly no eSATA, up to 84TB 6 Gbit SAS up to 240TB
Snapshots no / limited with performance impact yes, block- / pointer based, performance-neutral yes, block- / pointer based, performance-neutral
Storage Provisioning instantaneously, but without protection of
the data during RAID-Setup
instantaneously, data are protected from the
beginning
instantaneously, data is protected from the
beginning, RAID setup is also instantaneous
Volume Expansion no incrementally (disk per disk) yes, instantaneously, across multiple drives
Dedupe no no yes, inline, block-based
Real-Time Antivirus no yes no
Encryption without “backdoor“ no yes no
Replication File-based, Rsync, complex to set up and
manage, extra license
File-based, license included, easy and intuitively to
set up and manage
Block-based for shares and LUNs, highest performance
Snapshot Replication no no yes
Protection against silent data
corruption
no. EXT 4 file-system does not oer
protection
optimised - Copy-on-write with BTRFS
reduces the risk caused by file-system
inconsistency (additional protection by ECC RAM
in higher end ReadyNAS
®
)
ZFS writes data always to non-volatile media before
deleting them on the sender side. Copy-on-write with
self-healing and check-sums guarantees 100% file-
system-consistency
