**Update** After receiving a suspect drive, Home Essentials Direct replaced it with a new drive that has been working well in a home security system. file transfer and video scrubbing moves much faster. I purchased the 4TB Western Digital Red SA500 SSD for a security system install. Once installed, it was buggy and would not write any data. I unplugged it and plugged it into a Linux box to check the partitions. Low and behold, it said it only had 1.64TB available. Be careful with this one.

Answering the unanswered as there are so many forums where this question remains open. I can confirm that the WD RED SSD NAS 1TB (using a 2.5" to 3.5" cheapo chunky-style adapter) totally works in both the MyCloud EX2 and MyCloud EX2 Ultra dual-bay NAS devices. I tried JBOD, Spanning, RAID0, RAID1 and all are functioning as expected depending on your configuration choice. For my final configuration, I am personally using two WD RED SSD NAS 1TB in RAID0 for added performance and then use rotating USB HDD backups for any potential failure/recoveries that might happen. As an aside, I experimented with other brands of SSD without success. If you really want SSDs in your MyCloud EX2 or EX2 Ultra, then I'd recommend you get the official WD RED SSD NAS drives as they are ... MoreAnswering the unanswered as there are so many forums where this question remains open.

Bought this to add storage to an M1 Mac Mini. So far it's reliable and performing well. Files are always accessible right away with no lag or delay. Only had it a few months, so I'll see how it goes and update the review if things change.

I'm using a number of WD Red SA500 4TB NAS drives in a ZFS pool consisting of 6 mirrored vdevs. Overall pool performance is great, though average single disk write speed observed during two resilvering operations is only around 200 MB/s. (I've never seen it go above 380 MB/s.) It's not clear to me whether that's the sustained write speed of this drive or if there's a bottleneck (or deliberate throttling) elsewhere. As mentioned in the headline, it's still early days - the pool has only been in operation for a few months. Within the last few days ZFS started showing checksum errors for one of the Samsung EVO 860s that are also in the pool. I replaced it with an SA500. I'll try to remember to update this review over time to note how the SA500s are faring.

I recently purchased a Synology DS920+ and was intrigued by the prospects of being able to install an M.2 2280 SSD for a pool of fast cache on the device. This particular drive is in the list of “recommended accessories” on the B&H product listing for the DS920+, so I figured “great, I suppose I’ll get that one.” Turns out j should’ve done my research a bit better, because the DS920+ only supports the NVMe protocol for the M.2 2280 form factor, not the SATA protocol of this particular drive. So buyer beware if your purchasing this particular SSD for use in the DS920+, because despite its inclusion as an idea accessory it is not in fact supported.
I purchased this to replace a failing Seagate FireCuda ST2000LX001-1RG174 within a RAID array.For me the most important point was an exact or bigger match on the drive capacity. A smaller capacity, even by only a few MB would have meant that the drive would be unusable for it's intended purpose. Switching to a SSD to improve performance was the other factor.I purchased the 2TB SATA 2.5" form factor (in case this review somehow shows beside other form factors).The raid array sits on a hypervisor running multiple KVM VM's.

These were purchased as additional storage drives for a TrueNAS Core system. I have gone all SSD as I don't need masses of space and the fact that the drives are silent as well as faster is more important. They were detected by the system with no issue at all. The following commanddd if=/dev/zero of=benchfile bs=4k count=250000 && sync; rm benchfilewhen run inside a VM gives the following output1024000000 bytes (1.0 GB, 977 MiB) copied, 6.62751 s, 155 MB/s
Longer Life over performance, I hope! This is WD's answer to the need for an SSD with longer lifespan (5 year warranty) for use in a Network Storage device (NAS). There are faster SSD's out there, but if you want one for a NAS it has to be a SATA device at the moment and these at least offer more Total Terrabytes written than consumer grade devices for your laptop. Yes it is typically 3 or four times the price of a typical Spinning Hard drive of the same capacity, but it has no moving parts to wear out, makes no noise and runs cooler. The future of NAS drives.
I have gone all SSD in my TrueNAS Core system as silent operation and speed are more important than capacity. Drives were detected with no issue at all. When I run the following command on the TrueNAS Core shell.dd if=/dev/zero of=benchfile bs=4k count=250000 && sync; rm benchfileI get the following result.1024000000 bytes transferred in 5.568465 secs, (183892681 bytes/sec)I know you can get NAS SSDs with a better set of specifications but they can be quite a bit more expensive, so for my use case these seemed like a good middle ground.
5 year warranty and priced a bit more than comparable drives by "Brand C" (what I was planning to use). Performance is more than adequate for my needs. No apparent "major issues" with these drives that I could find, unlike the "Brand C" drives. I bought a pair of these SSD for a Raid-1 setup to use in a home system that runs 24x7 and needs to reliably run 24x7 with this Raid-1 storage array (mostly used to read data, not write it). I had a very short list of choices: "Brand S", "Brand C", "Brand I", and WDC. I have used SSD from all 4 of those manufacturers over the past decade or more. I decided on this SSD because it claims to be specifically designed for use in a NAS, and I presume that implies RAID setup, so I am hoping that is not a bunch of "marketing speak". ... More5 year warranty and priced a bit more than comparable drives by "Brand C" (what I was planning to use).
