WD Black AN1500 2TB RGB NVMe SSD RAID Card Review – 6.5GB/s, 5-Year Warranty and It Boots!

Take a look at the three SSDs below.  They are as fine of an example as you can get to demonstrate just how far we have come in flash technology.  On the left is the Intel 910 Data Center SSD.  Paul Alcorn posted his review  of this SSD way back in 2012.  It had top speeds of 2GB/s, IOPS up to 180K and way back then it was priced around $4000.  Oh… It wasn’t capable of booting your system.  Next up we have the Kingston DCP1000 Data Center SSD on the right that Sean Webster reviewed not so far back in 2017.  It would get you 7GB/s, 1 mil IOPS, cost thousands, but also also couldn’t boot your. Both of these SSDs were well above reach for even the most demanding of PC enthusiasts, as they should be considering they are data center SSDs. They shouldn’t compare…

Last but not least, we have the WD Black AN1500 NVMe 2TB SSD at center which, like the other two, is built on a RAID configuration and also has an enterprise RAID controller that makes it rather special.  Much different than the other two SSDs is that the AN1500 is a simple plug-and-play SSD that can run as your boot drive in your present PCIe 3.0 system, providing PCIe 4.0 SSD speeds.  It has a 5-year warranty, speeds up to 6.5GB/s, read and write IOPS above 800K, and the 2TB capacity we are reviewing today comes in around $549.99.

blankMost everyone we talk to says this SSD has a hefty price tag but we don’t think so.  By the end of this report we are confident you will see that, at least for the media professional where speed means efficiency, the WD Black AN1500 is an SSD that they simply can’t live without.  It is also the cheapest available for this kind of lightning fast performance, when that upgrade of your present PC system would be necessary for Gen 4.


The Western Digital Black AN1500 is a HHHL (Half height half length) AIC (Add-In card) NVMe 1.3 SSD that contains two M.2 SSDs set into a PCIe 3.0 x8 RAID platform.  The fact that this is a x8 (8-lane) SSD may be one of its only downfalls, but if you want that much power without building an entire new system yet again, that’s the way it is.  The SN1500 is bootable, capable of TRIM, and comes with a 5-year warranty.

It comes in capacities of 1, 2 and 4TB and MSRP pricing is listed at $299.99, $549.99 and $999.99.  A quick check of Amazon shows similar pricing to this with the 4TB not yet available.  The AN1500 comes with a 600TBW (Terabytes Written) per TB rating and performance is listed at 6.6GB/s read and 4.1GB/s write, so you are getting a plug and play SSD for your Gen 3 system that runs at Gen 4 SSD speeds.


When we disassemble the AN1500. we can see that there are two solid aluminum covers that assist in cooling the AN1500.  Once assembled heat is pushed away from the SSD via thermal tape and spreads across the external casing where it dissipates.  Inside, we have the Marvel 88NR2241 Intelligent NVMe Switch which is actually an enterprise level RAID controller intended for server use.


There are also two 1TB WD SN730 M.2 SSDs in a RAID 0 configuration which each contain a WD NVMe SSD controller, WD/KIOXIA BiCS4 96-Layer TLC 3D NAND flash memory and DDR4 DRAM buffers.


The only thing we want to mention about TLC memory is that it uses a SLC cache which is absolutely great for finding that performance reflective of former gen SSDs but, once that buffer fills, you may find performance to drop significantly as it clears.  This is only typical of extremely large media transfers.


Lastly, we wanted to mention that WD also makes available their WD Dashboard and Acronis True Image free of charge to its customers.  The SSD Dashboard is just about the most complete we have seen yet with a Performance Monitor that is truly old school, the ability to TRIM  your An1500 manually or automatically, firmware updates and it also contains a Secure Erase selection which we can just about guarantee cannot be done as this is a RAID configuration.


Something we have yet to mention is that this is a RGB SSD with full control within the WD Dashboard.  Not only are there several combinations that you can try on your own, but also, this SSD is compatible with several 3rd party RGB software applications.

    What if you wanted to swap out the WD 1TBs for a pair of Samsung Pro 980s? Doable?

      It may be doable…wait for it. Wouldn’t it be nice seeing this get 14GB/s performance…

      • blank

        I think the Controller might be the bottleneck in some cases.
        The “Gigabyte Aorus Gen4 AIC” is supposed to push 15Gb/s, but it still hasn’t been released yet, AFAIC.

    Good day!
    How does this card boot:
    – identification via recent chipset UEFI as NVMe
    – on-board Option ROM ? (so to speak X79/C60x-congegration´s wet dream)

    WD support unfortunately classifies this information as “industrial secret”.
    At least, from WD´s reply, this card does not need a motherboard capable of PCIe-bifurcation.

      Simple plug and play on a NVMe mobo… It is recognized as a NVMe SSD imediately.

      • blank

        Boots on C602 non-nvme-bios-chipset.
        Detected as “mass storage device” in BIOS pcie assignment.
        (A highpoint SSD7202 would show as a “pci-bridge”.)
        65°C at idle. No JBOD or RAID1 selectable.

    To boot or not to boot….depends on drive bios no?

    Can one replace the WD SN730 M.2 Nvme SSDs with Samsung M.2 Nvme SSDs like the 970 Evo Plus SSDs ?

    Probably no uptick in performance that would be noticeable but just curious.

      You *can* but you won’t like it very much. Non-WD SSDs on this card don’t do much better than a single NVMe drive, sometimes worse. I’ve tried 2x1TB 960 EVO, max read was only about 3.8GB/s. 2x1TB 970 EVO was even worse, 1.8GB/s read and 1.6GB/s write. I suspect something in the drive controller’s FW is setting an artificial cap when non-WD SSDs are detected.

        Perhaps there are compatibility issues with the Samsung drivers?
        Tried using with your OS´s stock NVME-drivers?

        Highpoint just released their 6200 series NVME PCIe 3.0 RAID cards that use the same Marvel 88NR2241 controller.
        As these cards are Plug & Play, too, maybe Highpoint´s RAID management controller can be used to tweak the WD/Samsung combo — can´t find a dedicated one for the 6200 series tho; don´t know if their 7200/7100 series ones function universally.

        doing that voids warranty?

    I want to use this in a Dell T440 server, because og the long MTBF and the low price. Do you think this will give any problem?

    I own a 2TB version of AN1500 and love it. I want to get another but not sure if it is possible to RAID 0 both the cards together? Thanks guys. It is installed on a 7,1 Mac Pro so I have the PCIe resources so would like to know the answer before a buy another card. Thanks

      I doubt it until one can access the individual drives in the AN1500.
      You would then couple two RAID 0 (one per enclosure) to another RAID 0 on top of that.
