As we speak we’re wanting on the Silicon Energy UD90 4TB SSD. I’ve accomplished a form of unofficial collection on cheap 4TB SSDs, overlaying the Fanxiang S660 and Lexar NM790, which makes this the third drive in that collection. Capability is a vital a part of selecting your SSD, and oftentimes, it would win out over uncooked efficiency. This logic is what prompted us to overview a few of the least costly high-capacity drives out there, and the Silicon Energy UD90 falls into that camp. With basically an identical specs to the Fanxiang S660, we’ll see how the UD90 holds up compared to the competitors.
Silicon Energy UD90 4TB NVMe SSD
Just like the Fanxiang S660, the Silicon Energy UD90 4TB is available in a single-sided M.2 2280 (80mm) type issue.
The UD90 sports activities a Phison PS5021-E21T controller, and the NAND is equipped by Micron and is 176-layer QLC with no DRAM cache. This is the same configuration to the S660.
The rear of the UD90 is barren, as you’d count on from a single-sided drive.
Silicon Energy UD90 SSD Specs
The Silicon Energy UD90 is obtainable between 250GB and 4TB capacities.
My overview mannequin is the 4TB, which is rated for 5000 MB/s learn and 4500 MB/s write. These are usually not high-end specs, however they do clearly exceed what’s able to a PCIe Gen3 drive. Silicon Energy hyperlinks to a separate doc the place they listing endurance, and the 4TB UD90 is rated for 2400 TBW. That is precisely on the road of 600TBW per 1TB of drive capability that I take into account the usual for endurance, so Silicon Energy will get a cross from me right here. Lastly, with the usual 5-year guarantee on the UD90 the general specs for this drive look fairly promising.
CrystalDiskInfo may give us some fundamental details about the SSD and confirms we’re working at PCIe 4.0 x4 speeds utilizing NVMe 1.4.
Take a look at System Configuration
We’re utilizing the next configuration for this check:
- Motherboard: MSI MAG X670E Tomahawk
- CPU: AMD Ryzen 9 7900X (12C/24T)
- RAM: 2x 16GB DDR5-6000 UDIMMs
Our testing makes use of the Silicon Energy UD90 4TB because the boot drive for the system, put in within the M.2_1 slot on the motherboard. This slot helps as much as PCIe Gen 5 x4. The drive is crammed to 85% capability with information, after which some is deleted, leaving round 60% used area on the amount.
Subsequent, we’re going to get into our efficiency testing.
