Try go-memcached - memcache server written in Go. It persists cached data to disk out of the box. Go-memcached is compatible with memcache clients. It has the following features missing in the original memcached:

• Cached data survive server crashes and/or restarts.
• Cache size may exceed available RAM size by multiple orders of magnitude.
• There is no 250 byte limit on key size.
• There is no 1Mb limit on value size. Value size is actually limited by 2Gb.
• It is faster than the original memcached. It also uses less CPU when serving incoming requests.

Here are performance numbers obtained via go-memcached-bench:

-----------------------------------------------------
|            |  go-memcached   | original memcached |
|            |      v1         |      v1.4.13       |
| workerMode ----------------------------------------
|            | Kqps | cpu time |  Kqps  | cpu time  |
|----------------------------------------------------
| GetMiss    | 648  |    17    |  468   |   33      |
| GetHit     | 195  |    16    |  180   |   17      |
| Set        | 204  |    14    |  182   |   25      |
| GetSetRand | 164  |    16    |  157   |   20      |
