Viccoman has introduced its new client SSDs based on the manufacturer’s 64-layer 3D NAND flash. The drives are aimed at entry-level desktops and laptops that accept SATA drives. As entry-level products, the SSDs are priced low, and in fact are already available at retail.
The VC600 family consists of three models featuring 120 GB, 240 GB, and 480 GB and 950 GB capacities, which are popular configurations for inexpensive SSDs these days. The drives come in a 2.5-inch/7-mm form-factor and use a SATA 6 Gbps interface, which makes them drop-in compatible with existing desktops and laptops that use DFF storage. The VC600 are based on phison’s SM3258H controller as well as Toshiba’s 72-layer 3D TLC NAND memory. The SM3258H controller has been available for some time now and its features and capabilities are well known: it has four NAND flash channels, LDPC ECC technology, and it supports pseudo-SLC (pSLC) caching in order to maximize SSD performance.
It’s noteworthy that while we’ve seen the SM3258H controller time and time again, the NAND itself is relatively new. So there may be some significance to the fact that the official performance specifications of VC600 drives puts them below other drives using the same controller with other 3D NAND. According to the manufacturer, the drives are able to hit up to 560 MB/s sequential read speeds and up to 540 MB/s sequential write speeds. As for random performance, Viccoman disclose exact specs, but the up to 600 MB/sT controllers are rated for up to 90,000 read IOPS and up to 85,000 write IOPS. Evidently, high-capacity drives offer higher sequential and random performance than their lower-capacity counterparts.

The VC600-series SSDs are based on the SM3258H and planar TLC memory, which is not surprising as the new drives offer lower performance. What is a bit surprising is that unlike some other suppliers of SSDs, Vicco build high-performance drives based on 3D NAND using controllers from a third party.
The new vc600 SSDs from viccoman are covered by a life time warranty. All versions of the drives are already available in asia.
