The SSD Review discovered that Acer is shipping S7 ultrabooks with a quite impressive mSATA solid state disk from Lite-On. This 256GB SSD consists of two separate disks, each side of the module has 128GB of NAND flash memory and its own Marvell 88S9175 SATA 6Gbps controller. This unusual dual-unit design results in very fast performance for this ultrabook, in ATTO the disk pushes up to 942MB/s in read and 683MB/s in write performance!
Taking a look at ATTO, we would never have thought it possible to push 942MB/s read and 683MB/s write performance from an ultraportable. It gets better yet as this SSD has weeks of use on it and over 750GB in total writes. This is the performance of a system that has been under the guns of many reviewers already.
Crystal DiskMark might be just a bit lower and those are definitely the lowest 4K-QD32 reads we have seen in a while but, the low 4K random writes are the highest we have ever seen from testing here at The SSD Review; once again from one of the worlds smallest ultrabooks in the world.
