    1111To determine which formats support which capabilities, use the ''--formats'' switch with pretty much any GDAL utility. Each driver will include either '''r''' (read-only), '''rw''' (read or sequential write) or '''rw+''' (read, sequential write or random write).

     15Briefly: use the warp memory and config cachemax settings. For example `gdalwarp --config GDAL_CACHEMAX 500 -wm 500`  uses 500MB of RAM for read/write caching, and 500MB of RAM for working buffers during the warp.
