Acer has entered the storage market with a range of 2.5″ SATA, M.2 SATA and M.2 PCIe NVMe drives, including the entry-level 2.5in SATA-based SA100 we are looking at here. Using a DRAM-less Maxio MAS0902A-B2C 4-channel controller, has the Acer SA100 got what it takes to mix with the big boys of the SSD market?
The Acer SA100 comes in a range of five capacity's; 120GB, 240GB, 480GB, 960GB and the 1.92TB flagship model we are looking at here. At the heart of the SA100 is a DRAM-less design Maxio MAS0902A-B2C 4-channel controller which looks after, in the case of the 1.92TB drive, four 3D NAND packages.
Sequential read performance is quoted as up to 560MB/s for the 480GB, 960GB and 1.92TB models with the 256GB drive rated at up 549MB/s and the entry-level 120GB drive, 561MB/s. The 1.92TB drive gets a Sequential Write rating of up to 508MB/s swiftly followed by the 960GB model at up 507MB/s. The 480MB drive is rated up to 493MB/s while the 240GB drive has the slowest write performance at up to 449MB/s. The 120GB drive is rated as up to 474MB/s.
When it comes to the official random performance, the 1.92TB drive is rated as up to 76,000 IOPS for reads and up to 77,000 IOPS for writes. The 960GB drive has the fastest random read performance, up to 84,000 IOPS (up to 72,000 IOPS writes while the 240GB drive has the slowest random reads at up to 40,000 IOPS (71,000 IOPS writes).
The 1.92TB drive has an endurance rating of 600TBW and Acer back the drive with a 3-year limited warranty.
