Torx Bits

If anyone is looking for the small torx bits for tearing apart hard drives I found this 21 piece screwdriver set at home depot for 4.99

What are the sizes? that would help

it dont say the sizes on the package but the description on the home depot web site says it Includes PH000, PH00, PH0 and PH1 Phillips bits, H1.5, H2, H2.5, H3 and H4 hex bits; SL1.5, SL2, SL3 and SL4 slotted bits and T5, T6, T7, T8, T9, T10, T15 and T20 Torx bits

DJ, Have you taken a lot of hard drives apart? I was wondering if T5 was the smallest I could use or do you or anybody else know if I need a T1-T4, and if anybody even makes them that small. I guess what Im trying to say is that I wonder which torx bit purchase should I go through with? My options are this one or some thing on amazon, ebay, and harbor freight. HF has 100 bit sett for $10.00

I took about 25 of them apart yesterday and the torx bits in that set worked fine
