Areca ARC-1882x 2nd Gen 6Gb/s SAS/SATA RAID Card Review – 4.7GB/s Transfer Performance!

RAID 5 TESTING – AS SSD

Some of the larger demands upon the performance of the controller is when raidsets with parity are introduced. RAID 5 in particular can be a challenging load for any controller, especially with SSDs involved. High throughput and low latency requirements of SSDs can be a big challenge, lets see how a Dual Core ROC fares against its single core equivalent.

In the compressibility tests we can definitely begin to see some differences in the write speeds of both controllers, as RAID 5 always tends to write slower.

CRYSTAL DISK MARK

Again we will go to Crystal Disk Mark for low 4K QD1 results (4K) that are ran outside of cache leverage.

    Need another 8 to 16 SSD’s to fully load RAID card setup. Would also like to see the impact of the 4GB cache and higher IOPS.

      The dropoff you see with the dual setup is just a programming glitch in atto disk benchmark. It used to be the same with transfers above 1GB/sec in earlier versions. Downloadn an older version to test with and you’ll see what I mean.

      Kind regards.

    “After that the results do drop off a cliff with the larger file sizes, as we get away from the stripe limitations of the dynamic disk.”
    What limit is this??? Have you ever considered that the ATTO benchmark uses 32 bit unsigned integers to store the results, so it cannot display numbers bigger than 4294967295 bytes/sec.

    There’s a typo on pg 9 – right top picture is for 1880ix, not 1882ix.

    Does the Crucial m4 drives compatible with the 1882 ?

    I’ve used Areca products for years in the corporate environment and like them quite a bit. The below statement about service, however, is laughable.

    Have you ever tried to get a card serviced? I have. When there is hardware failure you mail off your card and wait 2-3 weeks for it to come back. There is no option to provide a credit card & have another refurbished card cross-shipped to you right away. This means whatever system just failed is down for 2-3 weeks. RAID cards are about reliability, it means you need spare card hanging around if you’re worried about failure. Not exactly a cost effective solution.
