Question

I\'m getting ready to release a tool that is only effective with regular hard drives, not SSD (solid state drive). In fact, it shouldn\'t be used with SSD\'s because it will

Answer 1

write text file
read text file

repeat 10000 times...

10000/elapsed

for an ssd will be much higher, python3:

def ssd_test():

    doc = 'ssd_test.txt'
    start = time.time()
    for i in range(10000):
        with open(doc, 'w+') as f:
            f.write('ssd test')
            f.close()
        with open(doc, 'r') as f:
            ret = f.read()
            f.close()
    stop = time.time()
    elapsed = stop - start
    ios = int(10000/elapsed)
    hd = 'HDD'
    if ios > 6000: # ssd>8000; hdd <4000
        hd = 'SSD'
    print('detecting hard drive type by read/write speed')
    print('ios', ios, 'hard drive type', hd)
    return hd
