studios/storage space in Hackney

is anyone aware of any cheap artist/music studio spaces in Hackney with availability? i need somewhere secure to store approx. 1,000 records and some studio equipment – ideally i’d want 24 hour access and the ability to play music as well but that’s not essential. E5 is preference as that’s home – but E2, E8, E9 or N16 would also suit.
