The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
On the Test Bench today is a Yottamaster Y7000 Pro Gen4 4TB SSD and we are certain that you are asking yourselves that same question that we were not three weeks ago? Who the heck is Yottamaster? Yottamaster is a China-based flash storage business that ‘focuses on providing professional-grade storage solutions for a wide range of users, including individuals, gamers and businesses’. Checking Amazon, we can see that Yottamaster provides retail sales for RAID enclosures, SSDs, SSD enclosures, as well as Thunderbolt peripherals. They also have a very good reputation in general, having done a thorough search throughout the internet.
Now…for a bit of a background with respect to SSD manufacturers while we are here as well. There are ‘direct’ SSD manufacturers who ‘own the Fabs’ (semiconductor fabrication plants) and then there are third party resellers. Samsung, Kioxia (formerly Toshiba), SanDisk, Intel, Micron, and SK Hynix are a few you may have heard of who own fabs and manufacture their own SSDs, while Corsair, Patriot, OWC, Acer, PNY, Yottamaster and others pay companies to manufacture their SSDs from components, and then place their branding on that SSD.
Don’t get me wrong. Third-party companies do have input, but for the most part, that has to do with choosing the components and firmware in that SSD. It’s because of this that we sometimes review SSDs from different companies that have the same components with respect to the SSD controller, memory and sometimes even the DRAM buffer chip. The components in those SSDs are still made by the same ‘fabs’ that we had originally spoken of, just in different configurations. Why did we go here? Our review today of the Yottamaster Y7000 Pro will show this to be a DRAM-less SSD, which uses the same SSD controller and memory as that of the Acer FA200 we reviewed not a week ago. In fact, we even believe both SSDs were manufactured by BIWIN which we will get to shortly. Companies won’t confirm this of course…legalities. Check it out…
Now, if you look very carefully at the above Acer (BIWIN manufactured) and Yottamaster SSDs, you will see that the circuitry (and maybe even the memory) differs. It is a bit unusual actually as the early samples of the Y7000 Pro provided to reviewers initially were EXACTLY the same as that top Acer SSD, whereas our sample differs in the circuitry and NAND identification. We still believe this to be YMTC 232-layer 3D QLC NAND. Why? It is 3D QLC NAND on a single-sided PCB with each chip able to accommodate 1TB capacity. We only know of two manufacturers that have this capability at present and this is not Micron NAND. We have sent a detailed e-mail to Yottamaster and will update this report once a return has been received.
Both of these SSDs are single-sided DRAM-less PCIe 4.0 x4 (4-lane) NVMe 2.0 SSDs of the 2280 (22mm wide by 80mm long) form factor and both utilize the Maxio MAP1602a ‘Falcon Lite’ 4-channel NVMe SSD controller based on TSMC’s 12nm process. TSMC stands for Taiwan Semiconductor Manufacturing Company.
Yottamaster lists the Y7000 Pro as being available in 512GB, 1,2 and 4TB capacities with the 2TB capacity having 1200TBW but does not speak to TBW of the rest. As we don’t believe the 512GB would be 1200TBW, we might suggest that the TBW increases with capacity and is set at 300TBW (512GB), 600TBW (1TB), 1200TBW (2TB) and 2400TBW (4TB), as is the norm. As well, specifications are detailed on their website…again for the 2TB as 7000MB/s read and 6500MB/s write but nothing describes other capacity performance. We might suggest this being fair for the 2/4TB capacities but performance dropping somewhat for the 512GB and 1TB capacities, as is the norm.
Included in our packaging was the external box, a user manual, the Y7000 Pro 4TB SSD, a screwdriver, screw and what appears to be a heatsink base and one piece of silicone thermal pad. This differs from their website description as shown here.
We discovered this graphic while searching for specifications on the Yottamaster website. Our package seems to be missing the ‘Increased Cooling Surface’ and a thermal pad. Not really impressive, however we will say this. Gen 4 SSDs of this build are relatively cool running SSDs to start. That is a good thing. Could you get away with not using a cooler. We have…but we might not recommend it for heavy media editing.
The Yottamaster Y7000 Pro SSD comes with a 5-year limited warranty and pricing on their website is listed at $59.99 (512GB), $109.99 (1TB), $159.99 (2TB), and $284.99 (4TB). We find Amazon pricing to be significantly cheaper at $62.99 for the 1TB ($47 savings), $129.99 for the 2TB ($30 savings) and $239.99 for the 4TB ($45 savings). Check Amazon for current pricing now.
Now to some performance testing…
