Benchmark
I will use two Seagate Ironwolf 2TB 3.5 “NAS hard drives-ST2000VN004 (cache 64MB) for the following tests to see how well they will read and write.
So how to test the NAS read and write speed? Well, just map the IP address of this NAS directly on your computer, and then use the hard disk speed measurement software to test the read and write speed of this IP address.
What is RAID? If you’re not sure … you can check out the description on Wikipedia …
RAID (Redundant Array of Inexpensive Disksor Drives, or Redundant Array of Independent Disks) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
RAID 0 consists of striping, but no mirroring or parity. Compared to a spanned volume, the capacity of a RAID 0 volume is the same; it is the sum of the capacities of the disks in the set. But because striping distributes the contents of each file among all disks in the set, the failure of any disk causes all files, the entire RAID 0 volume, to be lost. A broken spanned volume at least preserves the files on the unfailing disks. The benefit of RAID 0 is that the throughput of read and write operations to any file is multiplied by the number of disks because, unlike spanned volumes, reads and writes are done concurrently, and the cost is complete vulnerability to drive failures. Indeed, the average failure rate is worse than that of an equivalent single non-RAID drive.
RAID 1 consists of data mirroring, without parity or striping. Data is written identically to two drives, thereby producing a “mirrored set” of drives. Thus, any read request can be serviced by any drive in the set. If a request is broadcast to every drive in the set, it can be serviced by the drive that accesses the data first (depending on its seek time and rotational latency), improving performance. Sustained read throughput, if the controller or software is optimized for it, approaches the sum of throughputs of every drive in the set, just as for RAID 0. Actual read throughput of most RAID 1 implementations is slower than the fastest drive. Write throughput is always slower because every drive must be updated, and the slowest drive limits the write performance. The array continues to operate as long as at least one drive is functioning.

RAID 0
The following results are taken from the speed test with hard drive type in RAID 0 …
CrystalDiskMark
CrystalDiskMark is a disk benchmark software.It measure sequential reads/writes speed,measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed, select test data (Random, 0Fill, 1Fill), provide theme support and Multi-Language support.
NAS Performance Tester
NAS performance tester is utility benchmark that test the read and write performance in megabytes per second of network attached storage connected through SMB/CIFS network shares.
LAN Speed Test (Lite)
LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB Drive, and Local Area Network (LAN) speeds (wired & wireless).
AJA Video System
AJA System Test Lite is a great way to test a storage system with a real world speed test. Designed with digital video and post production needs in mind, it emulates the writing and reading of video files to and from a hard disk, SSD, RAID, or NAS.
