For more than twice the market value since it has sticker on that says Synology. I get wanting to ensure hardware compatibility, but there's no reason to double the price. Synology recently (seemingly) learned their lesson about vendor locking drives, but I don't see them letting go of this. So let's do something about the stupid markup... Other than that it's RAM and it works. PLEX navigates faster on my 1522+ (not night and day). VMs will be happier. Install was simple. The rub just is the price... Review: Too expensive - I purchased this before I realized how crazy the price was when compared to non-Synology brands. Fortunately I discovered this before installing it, and I returned the product. Instead I purchased equivalent memory from OWC. It cost 1/8th as much, and works great! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09JNR33G6 | | Additional Features | Built and designed for maximum performance and reliability in Synology devices | | Best Sellers Rank | #27,803 in Computers ( See Top 100 in Computers ) #170 in Computer Memory | | Brand | Synology | | Column Address Strobe Latency | CL11 | | Compatible Devices | Devices Synology | | Compatible devices | Devices Synology | | Computer memory size | 16 GB | | Customer Reviews | 4.7 out of 5 stars 26 Reviews | | EU Spare Part Availability Duration | 5 Years | | Form Factor | SO-DIMM | | Item Weight | 0.05 Pounds | | Manufacturer | Synology | | Memory Form Factor | SODIMM | | Memory Generation | DDR4 | | Memory Speed | 3200 MT/s | | Memory speed | 3200 MT/s | | Mfr Part Number | D4ES01-16G | | Model Name | D4ES01-16G | | Model Number | D4ES01-16G | | Number of Items | 1 | | Number of Pins | 240 | | RAM Memory Technology | DDR4 | | RAM Size | 16 GB | | Ram memory technology | DDR4 | | UPC | 846504004409 | | Voltage | 1.2 Volts | ## Product Details - **Brand:** Synology - **Computer memory size:** 16 GB - **Ram memory technology:** DDR4 - **Memory speed:** 3200 MT/s - **Compatible devices:** Synology Device ## Images ![Synology RAM DDR4 ECC Unbuffered SODIMM 16GB (D4ES01-16G) Black - Image 1](https://m.media-amazon.com/images/I/51hPa3kNXDL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐ It's RAM for how much? *by D***X on 27 October 2025* What can I say... it's RAM. For more than twice the market value since it has sticker on that says Synology. I get wanting to ensure hardware compatibility, but there's no reason to double the price. Synology recently (seemingly) learned their lesson about vendor locking drives, but I don't see them letting go of this. So let's do something about the stupid markup... Other than that it's RAM and it works. PLEX navigates faster on my 1522+ (not night and day). VMs will be happier. Install was simple. The rub just is the price... ### ⭐⭐ Too expensive *by J***O on 30 May 2024* I purchased this before I realized how crazy the price was when compared to non-Synology brands. Fortunately I discovered this before installing it, and I returned the product. Instead I purchased equivalent memory from OWC. It cost 1/8th as much, and works great! ### ⭐⭐⭐⭐ Didn't really need it *by F***G on 30 August 2024* My first NAS, figured I'd also get more memory than the default. A little (more) reseach would have led me to realize that it was overkill for my situation. And so far it is has been, though perhaps I will use more of it as I get a chance to do some other things with the NAS. If I had it to do over again, I wouldn't have messed with the memory until later when I knew more about what I was doing. ## Frequently Bought Together - Synology RAM DDR4 ECC Unbuffered SODIMM 16GB (D4ES01-16G) Black - Synology SNV3410 400GB M.2 2280 NVMe PCIe 3x4 SSD - Synology 4-Bay DiskStation DS923+ (Diskless) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/386265646-synology-ram-ddr4-ecc-unbuffered-sodimm-16gb-d4es01-16g-black](https://www.desertcart.sg/products/386265646-synology-ram-ddr4-ecc-unbuffered-sodimm-16gb-d4es01-16g-black) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-19*
