I completely love world firsts. Much more than that, I really like seeing real technological innovation.
Not way back, we launched the Longsys Gen4 mSSD, and we have been lucky sufficient to obtain the drive instantly from Longsys Chairman Huabo Cai, giving us the chance to publish what turned out to be an sudden world unique. That 1TB SSD, no bigger than 1 / 4, delivered switch speeds of seven.1GB/s, a formidable achievement made potential by its revolutionary SiP (System-in-Bundle) single-package design.
By integrating the complete SSD into one bundle, Longsys eradicated almost 1,000 solder joints sometimes present in a traditional SSD. Fewer solder joints imply fewer alternatives for solder contamination, decreased part interference, and larger resistance to reliability points attributable to warmth and humidity. The method additionally cuts manufacturing defect charges from roughly 1,000 DPPM (Faulty Elements per Million) to simply 100 whereas decreasing manufacturing prices by roughly 10 p.c. In the long run, these financial savings and reliability enhancements translate into actual worth for the buyer.
Effectively… this morning, Longsys has raised the bar as soon as once more, and we’re lucky sufficient to have what will be the solely publicly accessible pattern in hand.
Introducing the Longsys Gen5 2TB mSSD, a drive able to exceeding 12GB/s switch speeds, with designs scaling to an unbelievable 8TB of storage, all packed into a tool no bigger than a 25-cent piece and only a bit smaller than a typical SD card.
As a lot as we’d prefer to suppose the totally built-in SiP (System-in-Bundle) single-chip SSD is a brand-new idea, it actually isn’t. In truth, whereas getting ready this report, we have been reminded of our personal overview of the Toshiba BG4 1TB SSD again in July 2019.
Because the beneath photograph reveals, the BG4 was remarkably related in that it additionally employed a single-chip design. The distinction, nonetheless, is simply how far the know-how has developed in only some years. Again then, a 1TB SiP SSD delivering as much as 2GB/s was thought-about a formidable achievement. As we speak, Longsys’ Gen5 mSSD pushes a really related idea to a wholly completely different stage, delivering as much as 13GB/s whereas scaling to capacities as massive as 8TB, all inside a single chip bundle the dimensions of 1 / 4.
The evolution is exceptional. Check out how these two drives examine…
We first caught a glimpse of the Longsys Gen5 x4 mSSD at Computex final month, the place we shared a quick look on the firm’s newest design. This latest iteration could be configured as a compact 2230 kind issue (22mm × 30mm), making it appropriate for space-constrained gadgets similar to handheld gaming methods and ultrathin laptops.
Our overview pattern arrived mounted in a gold-colored aluminum heatsink that includes an built-in copper vapor chamber. This design is meant to attract warmth away from the single-chip mSSD effectively whereas distributing it evenly all through the heatsink, serving to to take care of constant working temperatures underneath sustained workloads.
Extra particularly, in an effort to overcome the thermal challenges related to PCIe Gen5 mSSDs working in a particularly small kind issue, Longsys has developed a devoted high-efficiency cooling resolution that comes with VC (vapor chamber) phase-change liquid cooling know-how for speedy warmth switch and environment friendly dissipation.
The cooling system combines a number of thermal elements, together with TIM1 thermal gel, a graphene warmth spreader, a VC vapor chamber, and an aluminum alloy thermal enlargement card. In keeping with Longsys, testing demonstrated a big enchancment over standard cooling designs, extending peak 11GB/s efficiency from simply seconds to 181 seconds whereas permitting as much as 1,991GB of steady learn knowledge to be transferred earlier than thermal throttling happens, almost 2.5 occasions the sustained throughput of an ordinary PCBA SSD thermal resolution.
Designed particularly for the demanding KV Cache workloads present in AI PCs, this thermal resolution allows sustained PCIe Gen5 efficiency whereas sustaining the ultra-thin profile required by next-generation AI notebooks, successfully balancing most efficiency with compact system design.
mSSD stands for Micro SSD, and on this case, the complete storage resolution is contained inside a single System-in-Bundle (SiP). At its coronary heart is the Maxio MAP1802, a DRAMless PCIe Gen5 x4 NVMe SSD controller manufactured on a 6nm course of. The controller helps capacities of as much as 8TB and NAND interface speeds of 4,800MT/s, making it effectively fitted to the most recent technology of high-performance, compact SSDs.
Longsys has not said the precise NAND product used for the Gen5 mSSD. Reaching each an 8TB capability and 12GB/s-class efficiency from a single-chip design would nearly definitely require the most recent high-density, high-speed 3D NAND moderately than an older technology of flash reminiscence.
Longsys operates with a multi-brand portfolio and plans to broaden international distribution throughout its model lineup: FORESEE, Lexar and Zilia. The Longsys mSSD is now reaching month-to-month manufacturing capability of over 1 million items to instantly provide AI PCs and is optimized for KV Cache workloads.
