Intel's performance-segment mSATA SSDs, the SSD 525 series, started selling in Japan under OEM packaging, although freely available in ground stores (much like bare hard drives). Based on the LSI-SandForce SF-2281 processor and Intel's own 25 nm MLC NAND flash chips, the SSD 525 is available in four capacities: 30 GB, 120 GB, 180 GB, and 240 GB. The 240 GB variant stands out, with speeds of up to 550 MB/s reads with 500 MB/s writes; while the others max out at 500 MB/s reads with 275 MB/s writes. The 30, 120, 180, and 240 GB variants are priced at 5,180¥ ($57), 14,480¥ ($160), 20,800¥ ($228), and 26,980¥ ($295), respectively.
