The XPG SX300 has a SATA 6 GB/s interface, and is targeted towards power users who demand the utmost in speed and capacity. Read and write speeds reach an impressive 550 MB/s and 505 MB/sec respectively, with maximum 4K random write of 85,000 IOPs. The SX300 is available in capacities of 64, 128, and 256 GB in a small form factor. The SX300 utilizes a LSI SandForce SF-2281 controller and 25nm Multi-Level Cell (MLC) NAND Flash Memory.
The Premier Pro SP300 has a SATA 3 GB/s interface, and is an economical upgrade option. Read and write speeds reach 280 and 260 MB/sec respectively, with maximum 4K random write of 46,000 IOPs. The SP300 is available in capacities of 24, 32, and 64 GB in a small form factor. The Premier Pro SP300 utilizes a LSI SandForce SF-2141 controller and 25nm Multi-Level Cell (MLC) NAND Flash Memory.
The implementation of optimized firmware in the SX300 and the SP300 results in full utilization of the NAND Flash components, which translates to maximized storage capacity. According to ADATA, that's a 7 percent increase over other solid state drives that use a SandForce controller. This zero percent over-provisioning is implemented with no loss to performance or supported features, and can be realized only by 100 percent screening and sorting of the NAND Flash. Both the SX300 and the SP300 are applicable to Intel Smart Response Technology. With a SSD＋HDD hybrid setup, the mSATA SSD acts as a cache drive instead of main storage. Using this configuration, systems can reach speed boosts comparable to systems with SSDs as primary drive, while still enjoying the larger storage capacities of a mechanical hard drive.
The SX300 and SP300 are compatible with many motherboards on the market that have an mSATA slot, including Z77 series motherboards (Asus Maximus v Gene; Gigabyte G1 Sniper 3, Z77X, and Z77P, Z77, H77, P75, B75; ASRock Z77E-ITX), Z68-series motherboards (Gigabyte Z68XP-UD3, Z68XP-D3, Z68AP-D3, and Z68P-DS3), as well as laptops (Acer TM8481G; MSI GT70).
The SX300 and SP300 comply with ATA/ATAP1-7 standard. Supported features include S.M.A.R.T and NCQ command sets, and TRIM command. A 3-year warranty and a MTBF (mean time between failures) of 1,200,000 hours ensure long term usage free of worries. Pricing and release data have not been announced by ADATA, at this time.
