Understanding Uint8Array Memory Blocks Usage: 3 Bytes Data Consuming 3 Blocks (14 bytes per block)

Thank you for the detailed explanation; it all makes sense now! I've included my code below where I store data in the "compressedData = []" array. Is there a way to save this data with fewer storage blocks or space?

var lastTimestamp = 1692048524472;
var lastElevation = 0;
var compressedData = [];


function compressData(sample) {
  // Split sample into timestamp and elevation
  var parts = sample.split("/");
  var timestamp = parts[0];
  var elevation = Math.round(parseFloat(parts[1]) * 100);

  // Calculate deltas
  var deltaTimestamp = (timestamp - lastTimestamp) / 10; // Time difference in tenths of milliseconds
  var deltaElevation = elevation - lastElevation;

  // Mask values
  deltaTimestamp &= 0xff;
  deltaElevation &= 0xffff;

  // Create buffer with 1 byte for timestamp delta and 2 bytes for elevation delta
  var buffer = new Uint8Array(3);
  buffer[0] = deltaTimestamp;
  buffer[1] = (deltaElevation >> 8) & 0xff;
  buffer[2] = deltaElevation & 0xff;

	console.log("size = " + E.getSizeOf(buffer));
	console.log("remaining blocks = " +process.memory().free);
  // Update last values
  lastTimestamp = timestamp;
  lastElevation = elevation;
  compressedData.push.apply(compressedData­, buffer);
}

setInterval(function(){
compressData("1692048525472/294.35")
},500);




//the output is this:

size = 3
remaining blocks = 11820
size = 3
remaining blocks = 11817
size = 3
remaining blocks = 11814
size = 3
remaining blocks = 11811
size = 3
remaining blocks = 11808
size = 3
remaining blocks = 11805
size = 3
remaining blocks = 11802
