It was easily the match of the equally bargain Sabrent Rocket 4 as shown in the CrystalDiskMark 6 numbers below. I should mention that second-tier NVMe is still quite good in the grand scheme of things and the norm at the Atom 50's price point. Those benchmarks rate the fastest PCIe 4 NVMe SSDs during sustained transfers at around 7GBps while the Atom 50 was just below 5GBps. The Atom 50 turned in good PCIe 3 numbers and decent second-tier numbers over PCIe 4 in CrystalDiskMark 6, CrystalDiskMark 7, and AS SSD 2. That latter is about average for the price point. The drives are warrantied for five years or 650TBW (TeraBytes Written over the life of the drive) per 1TB of capacity. That's a hair pricy for a bargain PCIe 4 SSD, but it's still in that ballpark and doesn't consider any discounts you might see. The Atom 50 is currently available in 1TB/US$120 (tested) and 2TB/US$250 flavors. Also as mentioned, this is the first time we seen HMB perform up to snuff. As you'll see below in the performance section, it proved very proficient.Īs noted, there's no DRAM cache, Adata instead opting for HMB. Design and specsĪdata's Atom 50 bucks the trend of bargain SSDs based on Phison-based designs by employing a RealTek RTS5766DL to shuttle data to and from the SSD's 176-layer TLC (Triple-Level Cell, 3-bit/state) NAND. Alas, Sony's FAQ says thePS5 doesn't support HMB, which means the Atom 50 may not be quite as fast inside that console. It instead utilizes HMB (Host Memory Bus, aka your computer's RAM) primary caching, a technology we've seen less than stellar results from previously.
It's second-tier over PCIe 4, according to synthetic benchmarks, but it tied for 1st place in our real world 48GB transfers–a eye-opening performance considering the price.Įven more impressive, the Atom 50 managed that feat without a DRAM cache.
The Adata Atom 50 is one of the more affordable PCIe 4 SSDs on the market, which would seemingly make it a nice option for the PlayStation 5.
