Using X-Bench, we saw the 128GB model—the APPLE SSD TS128C—give the following numbers:

Seq Uncached Write: 134MB/sec (4k blocks) Seq Uncached Write: 158MB/sec (256k blocks) Seq Uncached Read: 68.5MB/sec (4k blocks) Seq Uncached Read: 165.8 MB/sec (256k blocks)

Random Uncached Write: 32.18MB/sec (4k) Random Uncached Write: 116.5 (256k) Random Uncached Read: 8.27 (4k) Random Uncached Read: 108.56 (256k)
