poofyhairguy Wrote:I do recommend a 7200RPM drive for parity, as it DOES increase the speed of writes.

Given the parity write mechanism of unRAID, the actual speed during writes is dictated by the slowest drive involved.

During the write operation, both parity and data drive need to perform a read before the write, for every single block of data. Since the platter needs to do a full revolution before the write operation, the faster disk will have to wait for the slower one to finish it's write before moving on to the next block.

Using a faster parity drive will result in faster write speed as long as the data drive is also fast. If you have a 7200rpm parity + 5400rpm data drive, the parity drive, although faster, will have to wait for the 5400rpm drive to complete each read-write cycle so the resulting write speed is the same as that of a 5400rpm parity drive.

If, however you have other 7200rpm drives in the tower, a faster parity would help slightly with writes to those particular drives.

If you use a cache drive, you have to know that data on that drive is not protected by parity until the cache transfer scripts kicks in and moves it to the protected array. This usually happens at night (but can be set to whichever time suits you best). A faster parity here would not make any difference in terms of perceived write speeds which is actually the speed of the cache drive itself.
