Samsung winning netbook SSD speed race

Leaves Intel for dust

Samsung is sampling netbook solid state drives (SSD) that consign Intel's UMPC products to tortoise status.

There are three new products about 30 percent of the size of a 2.5-inch hard drive and with capacities of 8, 16 and 32GB, using 2bits per cell multi-layer cell (MLC) technology. They all use a 3Gbit/s SATA interface and have read speeds of 90MB/sec. The write speeds are slower: 25MB/sc for the 8GB product; 45MB/sec for the 16GB one; and 70MB/sec for the 32GB one; that's a feature of MLC chips; as the capacity and so the number of chips rise then writes can be parallelized across chips to increase write speed.

In comparison, Intel's mini-card format 4, 8 and coming 16GB Z-P230 UMPC products use a slower PATA interface, read at a much slower 38MB/sec and write at a stumbling 10MB/sec. It's not that Intel's designers, based in IM Flash Technologies, can't build fast chips. The company will introduce a very fast 2.5-inch SATA product with 240/170 MB/sec sustained read/write performance later this year. It looks as if the company has deliberately built a cheap low-end UMPC product.

Samsung is building NAND flash for the same market but taking a high-speed approach. It could be that someone has mis-read the market. Alternatively it is developing so fast that there are already defined fast and slow netbook types.

Ultra-mobile PCs (UMPCs) or netbooks are handheld small products like the Asus Eee , Acer Aspire and HP Mini-note, which are used for surfing the net, social networking and e-mail. Dell is going to introduce a UMPC soon, one using SSDs with STEC controllers. STEC makes the SSD's for EMC's high-end Symmetrix dri8ve arrays.

The netbook market is growing with Asus saying it will ship 5 million units this year and with 6 million Aspires shipping from Acer's plants. That's trivial compared to desktop and notebook volumes but it's ramping up very fast.
