SLC-based Seagate Pulsar
Seagate has finally joined the SSD club and unveiled the Pulsar, an SLC-based enterprise class drive.
The Pulsar is a 2.5-inch drive, it's 7mm thick and it will ship in
three capacities ranging from 50GB, through 100GB to 200GB. While most
SSD makers opt for 40GB and 160GB drives, Samsung took the road less
traveled and added a few more chips in the mix. The drives are based on
Samsung's chips and their capacity is, in fact, somewhat higher, but
Samsung reserved 20 percent of it for redundancy.
As the Pulsar series is targeted at business users, reliability is
paramount, hence the redundant chips and the choice of SLC instead of
MLC. However, the drives don't feature a lifetime warranty, just a
Samsung stuck to SATA II on the Pulsar, but once demand for SATA 3.0
picks up, it will probably add support for the new standard. All three
drives offer 240MB/s read speed, and up to 200MB/s sequential write,
but sustained write speeds differ depending on the size.
We're not expecting the Pulsar to come cheap. After all, it's targeted
at the enterprise market, but hopefully Seagate will soon come up with
consumer oriented products as well. In any case, we're glad to see a
major play enter the market, as stronger competition means lower prices.
