Inevitably, one has to wonder why smaller drives arenвЂ™t given the same number of memory modules as larger drives. The same is true for mechanical hard disk drives (HDDs), where two drives that are otherwise identical will perform better on the drive with more cache memory. The larger a driveвЂ™s cache is, the faster its performance will be when sustaining large transfers or responding quickly to frequent data requests. Speaking of caches, larger drives may have proportionally larger allocations of cache memory. In other words, an SSDвЂ™s brain matters just as much as its brawn.

The intelligence of the controller when it comes to predicting which data to cache or how to shuffle data around to ensure the drive is always performing well has significant real-world effects. The SSD controller is absolutely crucial to performance as well. This is why SSDs erase memory blocks in the background that have been marked for deletion and do вЂњhousekeepingвЂќ to consolidate data, minimizing partially-filled memory blocks. This adds overhead to the driveвЂ™s operations and slows things down. However, if the block is partially filled, the drive first has to copy the existing data into a cache, erase the block, then write to the new empty block. If all the memory cells are empty, the drive simply writes to the empty space. ThatвЂ™s because an SSD has to erase an entire block of memory cells before writing to it. SSDs are fastest when they are new and relatively empty. This has an additive effect on performance since each independent memory module can send and receive data without affecting Smaller Drives Get Fuller Faster The more clusters you have, the more independent paths there are to move data back and forth.

With more clusters of memory chips, each connected to the controller by a dedicated data bus, the controller can read and write data in parallel. The controller is an intelligent device that decides where to physically store data on the SSD.
