Corsair is a company best known for their DRAM products, targeted mostly at the enthusiast market. In January, they entered the SSD market with a less than stellar product, but it was an important first step.
Things are improving though this week for Corsair Storage Solutions. The company is shipping a high-performance 256GB MLC SSD using a Samsung controller and 128MB of cache. The hardware involved is very similar to Samsung's own SSD product, which it currently only ships to OEMs. Samsung currently has no plans to sell the PB22-J directly to the channel, according to Samsung SSD Product Manager Brian Beard in an email.
The Corsair P256 delivers maximum read speeds of up to 220 MB/sec and maximum write speeds of up to 200MB/sec. Random read and write speeds were not immediately available.
Anticipation has been high for OCZ Technology's own high-end SSD using Samsung's controller. The company had a preliminary version working in their labs in February, and we were told that the company was targeting a late April launch for its Summit series. Our latest indications are that the Summit series will launch by the end of May, but the company may decide to show it off at Computex in June instead.
However, OCZ isn't too worried, as its best-selling Vertex series is doing very well. So well, in fact, that Intel has had to lower prices repeatedly in order to avoid losing too many sales to the upstart. OCZ recently launched a high capacity SLC Vertex EX series to compete directly against Intel in the enterprise server and workstation markets.
The Corsair Storage Solutions P256 SSD is available immediately from Corsair’s authorized distributors and resellers worldwide along with a two year limited warranty. The street price at most e-tailers at launch is around the $700 mark, with a part number of CMFSSD-256GBG2D.
quote: Why do you need cache on an SSD?
quote: It's used to store page mapping tables and other information that the controller uses to decide where to put a particular chunk of written data
quote: As a side note, the memory on hard drives isn't used as a cache either. It's mostly used as a write buffer and a read-ahead buffer.
quote: I really don't agree with you. You see, the info you are talking about is the most important in flash world. But to write 128MB would take a loooong time. And this information CANNOT be lost. So while they COULD use it to temporary store flash mapping tables, I really don't think it's more that 1/4 of it.
quote: But they can use it as cache and it still makes sense:why write half of a page when in 2 seconds a new write request could come for the 2nd half.
quote: Cache IS a read/write buffer.
