To address the one star review on this product and my own findings: First, I have a newly purchased Synology 1821+. I wanted to upgrade to an M2 NVME PCIE RAID 1 Read/Write cache for this unit. I tried the Seagate Ironwolf but later found out that the Synology is a Gen 3 device and not a Gen 4, so I returned the Ironwolf as they are Gen 4 and I was paying $110 more for no reason. I went with the WD RED SN700 x2. SanDisk was acquired by hard disk drive manufacturer Western Digital on May 12, 2016. OF COURSE they're going to use In-House technology, controllers, NANDs etc vs. any other company who have to source out controllers and NANDs. The only other exception is Samsung who also do In-House for their SSDs. Who cares that it's done by Sandisk - they've been around for years and the SSD is backed by WD's warranty. Officially, they're currently not supported by Synology - that's a new thing by them. They have their compatibility list of hardware, and guess what? You want a 400GB SSD from them that's been validated, you can buy that one, but it's quadruple the price of this SSD. No thanks. I'll accept the warning that it's not been validated by Synology. Even my WD RED CMR drives that I pulled out of my 1813+(which were compatible) and put into the 1821+ (officially not supported), but still work. I registered my warranty no problem. Not sure what the previous reviewer had issues with. Anyways, it works fine in the Synology 1821+ and even NASCOMPARES website did a review between this and the Ironwolf. Check that out if you're on the fence like I was. I have no complaints about these drives. Read more

First and fore most, it's double sided, the second side, the chips are located at the "end" of the drive, which is the furthest away from the NVME pin connecter. Stays steady at WRITING 1200megaBYTE/s until it maxed out. There's no such thing as cache, but the reads are all over the place, sometimes 2200mbyte/s for a couple of minutes, sometimes stays steady at 1000mbyte/s, sometimes drops to 900mbyte/s. Anyways, the lowest it dropped was 900mbyte/s. These were all tests done by moving large VM containers, smallest are 100GB each, some as big as 1TB. And yes, I use this drive mainly to host my VM containers off of. Creating and destroying VM containers require more "writing" than reading, and the read speed isn't that poor neither. TL;DR, it won't win any drag races, but since it acts like having no cache at all, it will ALWAYS offer STEADY performance even if you smash it over and over again. There is no recovery time for cache, as there IS no cache. (it acts like having no cache) And the speeds are much faster than QLC and TLC when their cache is exhausted. Cons, it still gets toasty like any other NVME drive, so make sure you stick a heatsink on. If you use it as an external drive, make sure you pay the extra $10 with nice metal chassis and includes thermal pads enclosures. This NVME drive costs a lot (with or without discount), so you can't skimp out and buy the cheapest NVME enclosure out there. Also buy the 10Gbps enclosure if you can afford it too. Read more

Bon produit en bonne état. Bien recu le colis Read more

I added two Western Digital 500GB WD Red SN700 NVMe SSDs to my Synology NAS DS1821+, and they've been working flawlessly. Setting them up as an SSD read-write cache has noticeably improved the overall performance and responsiveness of my NAS. One tip I'd like to share is allocating only 75% of the SSDs' capacity for the cache. By not filling them up to 100%, I've found that the SSDs maintain optimal performance and longevity. This prevents potential slowdowns that can occur when drives are fully saturated. Installation was straightforward, and the drives were immediately recognized by the Synology system. These SSDs are specifically designed for NAS devices, ensuring reliable operation under constant read and write demands. If you're looking to enhance your NAS setup, I highly recommend these WD Red SN700 NVMe SSDs. They've exceeded my expectations and have become a valuable part of my storage solution. Five stars!

Works great in my QNAP NAS for caching. No issues at all. Read more

I bought two of these drives, installed them on my NAS DS923+, in less than two months one of the drives failed. Configured an SSD Cache and the NAS is not even heavily used. Very poor experience Read more
